Mission Summary – Crew 223

Mission Summary – Crew 223

Our mission could be summed up in one word: adaptability. During those two weeks, we had to adapt to a whole different planet. The way we fed ourselves was different, our daily routines changed, the landscapes we saw were completely foreign. We had spent the entire year preparing for this mission with the previous crew (Crew 222), but it still was very different from all our expectations. We have learned a lot about how to live on Mars, science and friendship. We have learned how to evolve in an environment that we did not know and was sometimes dangerous. We got used to the Hab and this incredible station that we discovered on our first day.

Team members: (From top to bottom) Clément Plagne (Journalist), Aurélien Mure (Commander), Luc Fortin (Engineer), Blandine Gorce (Health and Safety Officer), Florian Delpech (Astronomer), Valentin Bellemin-Laponnaz (GreenHab Officer) and Marion Lebrun (Crew scientist)

We are a crew of students coming from ISAE-SUPAERO, an engineering school in France, and we prepared this mission with the second crew of our school, the Crew 222.

Food and plantations:

Food is a key aspect of Martian life and not only because it is a bare necessity for humankind. It has an important influence on human physical and psychological health. During the two weeks we spent in the MDRS, we exploited at best the production that could be harvested from the GreenHab. And it gave us a huge improvement on our daily habits:

  • Since most of Martian food is dry, having to harvest some fresh herbs and vegetables was a relief for most of us. It was essential to be able to gather some lettuce for a fresh salad or some zucchini flowers for an original meal. Having a place to grow crops is essential to the good mood of the crew and the well-being of their digestive system.
  • The GreenHab is the secret garden of our station, it looks like no other place. Supervised by our GreenHab Officer, we were able to grow crops such as wild rocket, spinach, cucumbers, sweet pepper, radishes, tomatoes, swiss chard… We also had an experiment testing the influence of music on plants. In fact, if we need a lot of crops to grow with few resources on Mars, it is essential to enhance the growth rate of the plants. Valentin experimented on radish to see if some precise noise sequence would enhance the production of proteins inside the plant.
  • We also tested a new type of plantation. Thanks to the Aerospring tower, we tested a vertical plantation and grew lettuce into foam. It allows to cultivate out of soil with a circular system of water and it is all lightened by LEDs. It was efficient to grow lettuce, but it is hard to quantify its efficiency because our two weeks mission was too short to see a significant different.

Daily routine and protocol:

Martian life is sequenced by strict protocol that must be the best for the health of the astronauts and the procedures of the experiences.

  • Our daily routine started with sports, then EVAs according to the weather and in the afternoon, we had a lot of time for experiments in the science dome or in the Hab. Having a day timed precisely helped us to get used to this different lifestyle. The protocols for EVAS are timed due to the depressurization and pressurization and because of the danger of going out on Mars.
  • On Mars resources are limited. We had to be aware of every kind of resource we were using and how we were using it. We changed the way we used water, not consuming it for showers or dish washing. Water is used daily but more than ever it must be preserved because it is limited and so hard to get on Mars. We preserved it so well that we only used only 7 Liters per person and per day. Aurélien and Benjamin, the commander of the crew 222 worked together to simplify the way we count water and give a visual signification of water use.

Human factors and teamwork experience:

Living as a crew is not always easy, but it is a key point for the success of the mission. During the two weeks, we learned a lot about each other, about cohesion and about communication.

  • Marion held two different experiments on communication. The first one consisted to test our communication in a foreign language by building LEGOs. And the second one consisted in testing our communication in situation of stress.
  • We worked a lot on team building through relaxation and positive psychology. It helped calm the stress of the crew members when they were having a hard time. It also helped understanding the dynamic of the Crew. We had a functional yoga program to get rid of the cramps after the EVAs. The conclusion on this experiment is that creating a safe space where everyone feels good helps a lot the efficiency of the mission.

Necessity on Mars and future exploration:

Although it is very exciting to go and explore Mars, this is the most dangerous part of going on another planet. You can become very aware of the danger and the fragility of your own life, when being in a suit in the middle of a desert with no communication.

  • During EVAs, we realized that having a functional life support was essential, so Aurélien and Luc spend a lot of time making sure that our life support would be functioning under any circumstances. They also worked our own life support that was supposed to be tested during the mission. Unfortunately, it was still a bit unsafe to test it, even after two weeks of improvements. We also tested the efficiency of communication in these dangerous situations. In fact, after an EVA where one of the Crew members had lost her earplug, we created a protocol only using sign language. We were able to test its efficiency during two EVAs and concluded on the necessity of having a coded language in case of emergency.
  • During our exploration, we realized that the shapes of Mars can be anything but what was expected so it is essential to understand the environment around the station. We had to experience working on a better understanding of our environment. The LOAC is a system that measure the particles in the air in order to better understand the climate. And the MegaARES measures the electrical field on the ground. The results will be analyzed by the the laboratory Laboraton and the scientist Jean-Baptiste Renard back in France.
  • Last but not least, discovering the universe on Mars is perspective that gives a new exploration point of view. Studying the sky would be useful for further space exploration to be able to observe the sun and be aware of any solar storm. Florian was able to observe the sun and searched for supernovas during the nights. He was able to make all the observations and he will analyze the results back at ISAE-SUPAERO with Eishi, the Astronomer of the Crew 222.

As a conclusion, I would say that we grew up and realized that no matter where you are in the galaxy, it feels good to have a place one can call home.

Final Mission Summary – Crew 222

Authors : Auzou Benjamin, Bochard Marie, Bourdeaud Nicolas, Kim Eishi, Prudhomme Valentin, Roiron Bleuenn, Sedbon Nina

The mission 222 is the sixth mission of ISAE-SUPAERO students in the MDRS. This mission is combined with the crew 223, also composed of students from ISAE-SUPAERO. Indeed, the two crews share the science, and prepared these missions together.

 

I. General Summary

As students, this mission has for us a pedagogic dimension. The preparation of those two weeks has been intense for one whole year and taught us to work as a group, to make decisions, but also to manage an association and a budget. Then here in the MDRS we learned to lead experiments on a very specific field, with the constraints that come with it. Furthermore, we evolved with six other people during two weeks and learned a lot on ourselves and on the others.

As a matter of fact, our crew was marked by a good cohesive spirit. During this mission we shared a lot of moments together, in the Hab and on EVAs. We talked a lot and shared our feelings during those moments. For example, at the end of each day, we had a moment called the “Word of the day”, where each crew member chooses a word to describe his/her day and explains it to the others. It was interesting to see that everyone had a different perception of the same sol.

After those two weeks, each of us has found answers to his own objectives of the mission, and as a crew we also tackled the group objectives, from a scientific and a human point of view.

The crew transition with crew 223 is ready, and we look forward to exploiting the results of all the experiments we deployed here.

Moreover, in 2021 a new crew of students from ISAE-SUPAERO will come here to continue the work we are doing for now six years in our association, the Club MARS of ISAE-SUPAERO. The strength of our crews is the cohesion, as we are preparing this mission together, and the fact that year after year we have a database of experiments and we share the experience as the veterans of the previous missions.

 

II. Science Status

During the past two weeks a lot of projects have started in the MDRS. We wanted to work on different aspects of a future sedentary life on Mars.

 

Martian food

Concerning plants and food we started several experiments that will continue with the second crew of ISAE-SUPAERO (Crew 223).

We grew Spirullina which would enable future humans on Mars to eat very nutritive algae. Today the Spirulina is growing in the aquarium and we hope that the next crew will taste it (it grew about 0,5 cm at the top of the aquarium). We also started the Aerospring moss garden. This garden can be placed in different environments and different temperatures. We are currently observing the development of roots (herbs and vegetables) in the garden with a highly controlled amount of ater (max 75L of water in the garden with every nutriments inside). Besides, we also wanted to compare this vertical garden with the same seeds in gelatin. At this moment we can’t observe any change inside gelatin but we can’t make any conclusion yet.

 

Martian environment

When we first arrived in the station we noticed the heavy and bulky equipment a human has to put on itself before going outside. That is why we wanted to test the Backpack combined with the LCVG for an EVA. Unfortunately we did not have time to test this outside the RAM because it was not sufficiently efficient and we did not want to take the risk to go outside with a dysfunctional equipment. At this moment everything should be working well and the next crew will be able to test it during an EVA.

We also put two experiments in place, taking measurements continuously during the day. The LOAC is sorting the air particules present in the air of the Utah Desert surrounding the MDRS. The results will be analyzed after the mission, by the researcher responsible for this experiment. The MegaAres is studying the electromagnetic field of Earth (before Mars …). It will be very interesting to measure the difference between day and night and depending on the hour of the day.

 

Martian house

We know that water is an essential ressource here on Earth and moreover on Mars. That is why we put in place a water consumption device in the HAB in order to know where the water is used to live on Mars. Today every cables are plugged and the next crew will be able to know precisely how they use their daily water.

 

A Human Civilization on Mars

The Human Factors experiments went very well. It was a special moment, every day for 13 days. Everybody participated willingly, it helped the crew be more bonded. We can’t disclose the purpose of the experiments now because the members of Crew 223 will undertake the same experiments.

 

 

III. Astronomy projects

Both astronomy projects have progressed with several gigabytes of raw data gathered and expected to be processed back at my school (ISAE-SUPAERO). Regarding the supernovae research project, nearly half of the target galaxies has already been imaged twice as part of the weekly observations, with the other half pending the run of the MDRS-14 telescope in the coming days. The astrophotography project has yielded beautiful images of the select deep sky objects. A couple of targets could not be imaged as planned because they were not visible for long enough after sunset. I am still looking forward to keeping on with both projects after the mission, in close collaboration with the Crew 223 Astronomer Florian Delpech and the astronomy club of ISAE-SUPAERO. I hope the raw data collected during the mission will be a valuable resource for scientific and training purposes.

CREW NARRATIVES

Commander Shawna Pandya, MD. – Callsign “Night Owl”

The MAU 001-MDRS 220 mission rep resented the first-ever “station-to-station” mission at the Mars Desert Research Station, and I feel honored and privileged to have served as a co-Commander during this historical mission. With it came a lot of firsts and learning lessons. I appreciated the opportunity to lead my crews with “military” and “consensus” governance models, although I must admit that in truth, there is a great degree of overlap between the models. No military commander can simply order their men into the line of fire – the team must agree to do so, which in and of itself is a form of consensus. As such, I did not notice any great degree of difficulty moving between the two governance models. This was also partially helped by the fact that the MAU Station crew, which operated on a consensus model, was always relatively small (2-3 crew including the Commander), therefore, it was very easy to build a consensus. Co-commanding was also a novel experience, and I enjoyed evolving with, growing with and learning from my co-Commander. Morning and night-time briefings helped us develop a shared mental model of our daily plans, and one lesson I learned was that it is best to err on the side of repeated-briefings to ensure the build-up of a shared mental model for both crew and commanders.

With regards to mission planning, in aviation, we talk about “staying ahead of the aircraft,” and the same is probably true of missions. This mission was task-saturated in nearly all categories – medical, arts and wellness, science and logistics – and in the future, I would work with my science and Executive officers to list all our “nice to have” versus “need to have” objectives well ahead of the mission itself, prioritize accordingly, and draft a mission schedule 2 to 4 weeks ahead of time. This crew in particular was good at stepping up and cleaning, cooking and doing dishes as needed, and made my job very easy, regardless of the station. One is not always so lucky, and future Commanders may need to plan to assign these tasks.

As the mission went on, the crew learned to work as a well-oiled machine, particularly when in small groups, and it is my observation that small groups tend to be productive groups. Spending more time at each station, developing more days with station-specific programming, and observing the station-specific culture that develops would be interesting, both to see how each station develops through the course of the mission, and also to observe how different-sized groups worked together.

I particularly enjoyed teaching, demonstrating and drilling the medical protocols during this mission, and would continue to emphasize this education and its application to EVA in future missions.

As I told my crew today, I learned and grew from my interactions with each and every single one of them, and while this may be the end of one adventure, from the bonds and friendships formed here, it is merely the beginning of the next.

Commander John Hanacek, MA – Callsign “Hummer”

What is power? I have studied this question academically, and now on Mars I have experienced a new level of immediacy and directness to this question. Personal power was the deep running theme of this mission for me. I was forced by circumstance to claim my personal power and my mandate as a leader in the face of strong personalities. I came here prepared to let go of my programming and tap into the inner permission to love myself enough to let go of doubts, fears and limitations – and to fully accept the leader within myself to emerge though this experience.

Establishing power was a running theme both on an operational level as well as metaphysical. I began my commander rotation at the Mars Academy USA (MAU) station, and I felt forced to quickly become comfortable with the freezing Martian nights in the austere habitat without consistent electrical power and just some small propane heaters as we worked to establish electrical systems for the MAU station. At the same time, I was establishing my power as a commander and leader.

The two stations operated on different governance models, MAU on consensus and MDRS in a more traditional hierarchical way. This became a source of growth for me, as I found myself feeling out in the cold when interacting with the MDRS commander, having to constantly ask for briefs and finding myself being talked over and what I felt as subtle undermining in the first few days. I have come to realize that it was a gift –begging me to step into my own personal power and speak for myself. In addressing these challenges directly with my Co- Command during Sol 11-12, I felt I better understood how to manage using Command and Control without being overbearing.  My MAU station mandate was immediately more comfortable as it fit my personality – facilitating consensus and creating time and space for decisions to emerge from the crew.

The first week went by in a strange kind of fast eternity where every night was a new challenge, and emotions often ran raw as I refused to back down, and embraced being my authentic self in always vocalizing concerns and truths, even when it did prove unpopular. Before I switched stations to command MDRS, I first took a three-day trip back to San Francisco, CA, Earth to work on a business project. This was surreal to say the least. I found that the Earth looked different and yet I recognized it more clearly. I reflected on how the station-to-station scenario seemed a smaller microcosm of what goes on every day on Earth: power shifting, jostling for authority and negotiation of sovereignty.

When I returned to MDRS I found myself able to interpret the command hierarchy style of leadership and within it, to communicate with authority not domination. I felt that also shifted my relationship with the MAU Commander – we synergistically seemed to reach an equitable distribution of power, authority and sovereignty. The commander who had acted in my place changed the paradigm and brought an entirely new level of operational order and mental transparency to authentical daily plans and intentions. I enlisted her as my XO and we continued a trend of what I see as the golden age of the station-to-station mission, where clear communication, visible plans and balanced power and empathy reigned.

In all, I enjoyed my time at MDRS and MAU – even when it hurt. I feel transformed from my time on Mars, and I feel like this full crew and the stations themselves will always be in my heart. I found my power here on Mars -my ability to stand tall on shifting ground and feel safe – to give orders, to take criticism and to grow with a crew made up of very different personalities. More than the exploration of Mars, this mission was an exploration of myself and the nature of power. I feel I now have been gifted with a secret to share as my final words – within me is the entirety of the all one and also the specificity of a unique authenticity I refer to as myself. The ability to accept both the light and the dark equally yet choose which one I want to express. I accept my shadow as I shine my light. I remember that everyone is me and I am everyone, and I accept that I have preferences and specifics. The ultimate power is in choice itself, in meeting all happenings and interactions with full awareness and complete memory. What will I express as I embrace the complete unity of myself? How will I be with myself in my many faces? The choice is mine if I make it so, and that is where power truly lives.

Commander Connie Delisle, PhD. – Callsign “Coyote”

Space and time have always been a fascination. Prior to MDRS, that meant introspection and personal discovery of boundaries to set and borders to let go. In in Mars flow of time I feel it’s bigger than that – and non-random. Rather, an intricate design to clear the inner space and for all to share insights as a collective wisdom for those going back to Earth or headed for other far away planets and galaxies.  This first ever-Station-to-Station mission has answered some questions but ultimately more so challenged my theories and conviction. It was a completely unexpected honor to serve as MDRS Commander for Sol 8-11, leading me to affirm that even on Mars my true calling is of service and support to leadership. As Commander, the following three insights are offered: First, self-monitoring and day-to-day crew checks for wellness, adjustments to operational tempo and re-alignment with Mission Objectives requires extreme and ongoing vigilance. Second, Mars is a team sport. I found that delegation and follow up worked equally well on Mars and it does on Earth; the main difference is in the cycle times being very short. Third, crew diversity and culture are powerful. In seeing and feeling through other’s perspective, then patience and understanding transformed hurt to healing.  On a personal note, it was entirely freeing that Crewmate and Astrological Researcher Marufa Akhter Bhuiyan validated for me, the realness of living in imaginary time- something I’ve been doing on Earth without knowing what it meant. Even though current time was short as MDRS Commander, teachings and reflections from MAU and MDRS Crew along with MDRS Director and her team will live on through time immortal.

Morgan Kainu – Callsign “Grass Snake”

This mission was a complete success with respect to teamwork and spiritual growth together and has paved the path for future endeavors together. I would be happy to do a future mission or research with any one of the crew in the future.

Matt Wise – Callsign “Fox”

This was a unique opportunity to practice innovation and group problem-solving in an isolated environment.

Johannes Nordsteien Svensøy  M.D., M.Sc.EMDM -Callsign “Raven”

This was an opportunity to solve real-life challenges in a simulation, which is critical if you are going to push the boundaries in austere environments and extreme medicine.

Project Reports

Johannes Svensøy MD callsign “Raven”

Butterfly iQ Ultrasound tele-guidance, Butterfly Network.

The Butterfly iQ was brought onboard the current mission with much appreciated help and guidance from the Butterfly Network. The Butterfly iQ is a revolutionary handheld Ultrasound System integrating the most commonly used probes in medical ultrasound imaging into only one probe. The device is operated from small-screen devices such as mobile phones or tablets, making this the perfect tool for ICE (Isolated, Confined and Extreme) environments such as this MAU-MDRS Mission. The Butterfly was integrated into teaching and training of both medical and non-medical personnel, particularly into trauma scenarios in the field. The objectives of the training were device familiarization, and to get a hands-on idea of POCUS (point-of-care ultrasound) and FAST (Fast Assessment for Sonography for Trauma) protocols. The Butterfly Ultrasound was also used during simulation for assessment of an injured astronaut after evacuation and decompression into the station. The Butterfly Ultrasound and the program is easy to operate, and with the tele-guidance tool, a medical expert can guide, analyze, and explain the findings to the operator. This project was met with an overwhelmingly positive response from both medically and non-medically trained personnel, and all were able to appreciate its use case for future missions and simulations. My recommendation is to further integrate the Butterfly and its multiple capabilities into more simulations in future missions. Appreciation and thanks to Butterfly Network for the possibility to test this tool in austere environments such as here on Mars.

John Hanacek MA

Virtual Reality and Spatial Computing Demos

Objectives: Give the crew access to cutting edge Virtual Reality (VR) and Spatial Computing/ Mixed Reality headset technologies.

What was done: Brought an Oculus Quest VR headset and a Magic Leap Spatial Computing headset, both loaded with applications.

Did not achieve objectives, only one member of the crew experienced just one device.

Needed to schedule dedicated time for the activity, yet this mission had so many activities that it often got bumped due to other projects taking immediate precedence as being more mission relevant.

Future plans are to once again bring the devices, yet firmly establish a time window of at least an hour to demonstrate them. Next time I will need to get into the schedule much earlier and stay persistent that it is mission relevant to have the crew experience these next generation technologies.

AvatarMEDIC HoloTRIAGE ™ Application Testing

Objectives: Conduct user testing on the newly developed prototype HoloTRIAGE mobile phone AR application for multi victim trauma scenario training. Develop survey for said testing.

What was done: Brought application loaded on a mobile phone, had any interested participants sign MNDA with AvatarMEDIC company

Achieve Objectives? Partially. Did not find time to conduct any tests but we develop a survey which can be used for subsequent tests.

Why not achieve? Application was only completed within the last four Sols of the Mission, not leaving adequate time to slot in a testing time period into the already crowded schedule.

Future plans are to test the application on Earth and further refine the application and the survey methods. Additionally, utilizing the training from this MDRS/MAU mission to inform additional curriculum modules for the application and enhance the quality of the training.

Teleanesthesia “Vapojet” Simulation Training

For pre-simulation training, telepresence was proposed to train the crew members in basics surgical interventions such as Debridement and Suturing using simulation tissues. During the sim, the crew learnt and conducted the teleanesthesia protocols using the 3D Printed VAPOJET TM

Mars Governance Models

Designing future strategies for implementing a form of governance model in isolated and remote groups to include ethics, rules and regulations. What infrastructure model is needed to ensure optimum health, wellbeing, increase productivity and collaboration for crews.

The implementation of two different governance models for each station was an interesting experiment for the crew teams. The MAU station adopted the consensus model and MDRS station adopted the “military hierarchical” model. Both crew teams experienced the two models with positive outcomes and was able to live and work together and quickly adapting to the station environments and the limitations and restrictions imposed during the mission.

FOLDABLE MICROSCOPE PROJECT:   

Paper foldable microscope was assembled by crew and used to detect microorganisms and potential bacteria and contamination in the soil samples collected during the geological EVAs.

Meals for Mars Project – PI: Sian Proctor PhD

The Elements  meals used freeze-dried “meals”  specifically designed for long duration spaceflight missions for astronauts and crews in austere I.C.E was implemented in the mission for several days with selected crew participants.

Station to Station Data Link

Objective- Create a wireless data link between MDRS habitat and MAU station

We emplaced mesh network access points between MAU and MDRS to create a station to station localized network for sharing files and operational data.  Lack of solar panels and batteries forced us to run power cables to each access point, however the data was relayed very effectively via wireless signal.

Result- The concept was proven, but full point to point connectivity failed due to insufficient access points to span the distance between stations.

Future- In the future having more access points for the mesh network will alleviate connectivity gaps.  I’ve designed a one-piece wireless repeater which solves this issue.  Teams will be able to deploy a modular mesh network to effectively expand station connectivity

Mars’-bucha Bacterial Production Study

Digestive health and, more specifically, the gut bacteria biome are critical considerations for long-term habitation off world.  Complex solutions requiring resource intensive production will be less than optimal from both a transport and operation standpoint.  Kombucha can be easily produced and requires only tea, sugar, and water.  The bacterial culture is extremely resilient and not only reusable but self-replicating after only 7-14 days in ideal conditions.  Producing such a beverage is both healthy and has a positive effect on morale.  While a number of sugar sources are available this study assumes sugar cane grown in the greenhab as well as various types of tea which will also provide excellent oxygen production and a good cellulose fiber source for production of other materials.  The bacterial culture can be easily transported from earth or carefully isolated in the hab.

In our study we began with a 3 gram sample of isolated bacteria, mixed with 1 gallon of brewed tea and sugar, and allowed to propagate in a warm, dark container.  After 8 days the bacteria colony had formed a thin layer in the liquid.  These bacteria consumed most of the sugar and caffeine in the liquid and reproduced large quantities of beneficial bacteria.  75% of the liquid was drained from the container, bottled, and mixed with approximately 2oz of sweetened fruit, tea, and/or spices depending on the taste of each crewmember.  After 3 days of second fermentation the carbon dioxide expelled by the bacteria consuming sugar gave the beverage a slight carbonated kick and the color had changed to deep reds and golds depending on the ingredients added.  They were also delicious!  The remaining liquid was enriched with sugar and left to sustain the bacteria colony until we’re ready to produce the next batch of Kombucha.  As of this writing a second bacterial layer has formed from the original colony.  This layer could be separated and used to begin an entirely new container of Kombucha.

The health benefits of Kombucha are far reaching, as is the simple enjoyment of a tasty beverage.  Additionally, the fermentation process produces CO2 which would be beneficial to plants growing in the green hab. The greenhab, in turn, is a warm environment, a perfect location from producing Kombucha.  Production is non-resource intensive and the yield is high. This is a perfect option for a Mars habitat.

GOLDEN BUBBLE

Objective- Use the Golden Bubble medevac device in an analog Martian environment and successfully deploy, load, and transport a mock-casualty to higher medical care.

The Golden Bubble is a pressurized emergency medevac device comprised of a backboard, inflatable transparent membrane, and life-support systems. The Golden Bubble is designed to be used in emergencies to provide a pressurized, clean-air environment during a medical emergency.  The casualty is strapped onto the backboard and then the membrane is inflated around them creating a protective bubble.  Access points along each side allow first responders to assess and stabilize the victim without exposing them to toxic or low-pressure, low-oxygen environments.  The inside pressure is regulated to a specific atmosphere and excess C02, fumes, dust, and other contaminates are vented to the outside.  The purpose of this device is to extend the Golden Hour and give first responders more time to move a casualty to higher care.

In this case we used the Golden Bubble as a medical scenario training aid.  A mannequin was used as a mock-casualty and was subsequently put inside the Golden Bubble, assessed for injuries, and transported by foot, then by rover, to the nearest airlock for higher medical care.

Result- The test was highly successful, and the Golden Bubble performed better than expected in many ways.  It was relatively easy for any individual crewmember to carry and deploy.  A longer version will, however, need to be constructed for patients taller than 72” and improved air tank capacity will be necessary for a production version.

Future Plans- Going forward I will continue to improve the functionality and ergonomics (particularly for patients wearing EVA suits) of this design and create a more streamlined and functional production version.

ISANSYS Sensors

The ISANSYS Lifetouch 20g sensors, blood pressure cuff and pulse oximeter were deployed on this machine to see how they would fare in an ICE environment. The sensors are capable of measuring heart rate, respiration rate, heart rate variability, one-lead EKG and accelerometry. When paired with the other two devices via Bluetooth, the system is capable of measuring blood pressure and pulse oximetry as well. In this mission, 4 patches were deployed on 4 crew members (2 male, 2 female), as a test of both longevity over a 2 week mission, and as a test of hardiness, as all 4 crew members spent one week at the MDRS Hab, and one week in the MAU Station, in tents in a winter desert environment. The Lifetouch Patches have been previously deployed in parajumper and military field exercises, the Cleveland Clinic, in Antarctica with the NASA Johnson Space Center Exploration Medical Capability team in drysuits, underwater in wetsuits, and in parabolic flight. In this demonstration, the patches were both used to collect biometrics, as well as make notes of how the patches reacted when used continuously over a two-week mission, with intermittent battery replacement as needed, as well as with continuous exposure in the cold desert environment. Subjectively it seemed that sensor battery life diminished in the tent environment. There were some issues with QR code reading, initially with pairing the blood pressure cuff to the ISANSYS tablet, and later on with the pairing of the tablet to the LifeTouch patches. These eventually resolved, but from previous experience, it seemed like the patches required a new session to be started every time a session was transferred, rather than transferring back to a previous user. Of note, the tablet’s ability to read QR codes seemed to behave better once the tablet was connected to the Internet. By the end of the mission, most batteries had failed, and sessions were either intentionally ended after catching up on all data, or ended prematurely with batteries dying, resulting in the loss of some data. Early on in the mission, the ISANSYS/Stark team confirmed that they were able to view uploaded data on the secure server. This ultimately represented a successful demonstration of the Lifetouch system in an extreme environment. In the future, to minimize data loss, it may make sense to schedule “maintenance” Bluetooth catch-up sessions at 3-4 day intervals. With future deployments of the Lifetouch Patch, it may be interesting to have the subjects keep a journal of particularly notable physical, physiological or emotionally events, and later correlate those events to sensor readings. As a final point, the timestamp on the table is 2 hours ahead, and this was not corrected so as to not interfere with the tablet settings.

EVA Biometrics Study

The EVA biometrics study looked at crew wellness parameters pre and post-EVA. Parameters measured include blood pressure, heart rate, pulse oximetry, weight, and questions assessing hydration status and subjective notes pre-EVA, and questions regarding subjective assessment of physical exertion, mental exertion and emotional distress. The study succeeded in acquiring some data points, but there is room for improvement as to how the study is conducted in the future. Firstly, the vital sign measuring equipment was only available at MDRS station, hence only EVA teams leaving from MDRS station could be consistently assessed. In addition, given the large size of the crew, the number of times a single individual was assessed was limited, usually ranging between 0 to 3 times over the course of the entire mission. Lastly, there were moments, when, either due to time constraints or simply forgetting, that pre or both pre- and post- data point collection was missed, limiting the value of the results. Future studies would do well to regularly collect pre- and post- EVA data. From the data points collected, however, most crew members seemed well-hydrated pre-EVA, no crew members lost weight from dehydration based on the data, and no vital signs were grossly abnormal.

Psychological Resilience in ICE Environments Study

The psychological resilience in ICE environments study was conducted in partnership with Dr. Nathan Smith of the University of Manchester, and this study was initiated in partnership with NASA as an evaluation of psychological resilience of astronauts, and later expanded to adults on expeditions of >10 days in other expedition and isolated and confinement environments. The study consists of both pre and post-mission surveys, as well as twice daily mission diaries. There were difficulties with obtaining data due to the initial state of emergency at the start of the mission, and accessing the digital surveys, which put those partaking in data behind from the outset. In addition, the study data may be affected by the highly dynamic nature of crew members moving in and out of “quarantine,” affecting the data. Ultimately, because of the limited internet, nearly all surveys were completed in retrospect, also possibly affecting the data. These notations will be made when the final data is sent back to the primary investigator. If incorporating this study into future missions, it would make sense both print paper copies ahead of time, so as not to be hindered by technology lapses, and also to schedule time pre, post and in-mission to ensure that data is captured daily.

MAU Ambassadors Program

The MAU Ambassadors Program was started during the second week of the MAU Command under Commander Pandya, with one Officer from MDRS coming to spend a night and part of the next day with the MAU crew to foster cross-station professional competencies, relationships and cultural exchanges. During its initial run, 3 MDRS officers, including the MDRS Journalist, Engineer and GreenHab Officer spent one night each at the MAU station, and all expressed positive sentiments about their stay, commenting on either the view from MAU station, the time spent with the MAU crew and/or discussing mission logistics. All in all, this initial trial run of the program was promising, and may be worth incorporating into future missions.

Mission Summary – Crew 219

ARES Mars Desert Research Station Mission Summary

ARES MDRS Scientific Research and Engineering Testing

Astrobiological Research and Education Society (ARES)

 

Mission Overview:

            The exploration of Mars has a myriad of physical and technical challenges that will demand the greatest ingenuity and moxie ever displayed by human explorers. To meet these challenges, STEM professionals use Mars Analogs like the Mars Desert Research Station (MDRS) to evaluate their procedures and technologies in a setting where challenges occur in real time. This provides feedback that permits space agencies to conduct safe and effective missions to Mars.

The Astrobiological Research and Education Society (ARES) was established to unite astrobiology scholars in the search for life and the study of Earth-born organisms that leave Earth. ARES engages in Mars analog studies for two justifications: to define the methods that which might detect life on Mars and to study biological sustainability techniques that facilitate long-duration habitation. Crew 219 came to MDRS with a variety of scientific and engineering-related challenges to expand on this work.

Overview of Research

EVA Operations:

Crew 219 executed eighteen Extra-Vehicular Activities (EVAs), serving five of our seven projects. These projects collected data and we will begin post-mission analysis after our return. EVA’s consisted of geologic sampling for both mineralogical analysis and biological viability. We implemented Standard Operating Procedures (SOPs), which are available as separate appendices.  After each EVA, biometrics data were collected for evaluation by the HSO.

 

Biometrics and Neurobehavioral Research Pertaining to Cardiovascular Health during EVAs

This was a two-series data collection taken concurrently: Series I focused on collection of biological metrics and Series II focused on collection of neurobehavioral metrics on varying schedules. Data collection for this research is nearly complete.  It should be noted that some metrics were skipped or eliminated at the discretion of the HSO:

  • Respiratory Rate (B4)
  • Modified DAN OSNE (N3)
  • Lower Extremity Measurements (B2)

Data collected was compiled in individual folders and broken down by Average (AVG) of individual metrics minus the Preliminary Collected Individual Metrics, Minimum Value (MIN), Maximum Value (MAX), Variation between MIN and MAX, and Variation from AVG and Preliminary Collected Individual Metrics.  The latter values were recorded on a master spreadsheet to compare crew metrics by averaging each and deriving the deviation from the average for each crewmember at each metric.  These will be combined with EVA data (time, duration, difficulty) and Sleep Logs to determine if the variations in and between crew members for each EVA were indicative of correlation between EVA and cardiovascular health decrement due to the high stress (physical and neurological) of long duration EVAs.

Further research would utilize in-situ recording devices during EVA, allowing for persistent data collection.  One could then derive EVA duration and cardiovascular workload within simulated environments such as MDRS and extend into real-world off-planet science.

 

UAV Transport and Deployment

The objective of this project was to flight test a specialized quad-rotor UAV developed at Florida Tech. This preliminary phase of development is focused on the transportation, assembly, and deployment in a field environment. While later phases will focus on the more specialized performance aspects of the UAV, this mission sought to evaluate challenges involved in transport, deployment, and flight testing.

The UAV was assembled, and its camera assembly tested. During initial power-on, motors 1 and 2 tested successfully, but motors 3 and 4 failed to turn. Computerized diagnostics reflected the presence of the failing motors, so it was determined that further testing should be postponed in favor of fault isolation.

Fault isolation continued through the duration of the mission and revealed mechanical and electrical quality control issues that were not apparent when the UAV was collapsed into transport configuration. Due to a thorough investigation by the Engineer and his documentation of discovered issues, the UAV’s design team will have an evaluated list of repairs and improvements to make before it returns with next year’s mission.

 

Dust Mitigation for Optical Mirrors

Many telescopes rely on the detection of light after being reflected by mirrors. Environmental dust on these mirrors can cause obstructions or distortions of captured imagery. Removing it without damaging the mirror is time consuming. In this project, we tested known cleaning methods for optical mirrors in a Mars-like environment. We brought two 135 mm mirrors and a mount which were set up outside the Hab for 4 Sols. This served as a baseline for the effects of weather on an open optical mount. The mirrors were brought inside and given several days to remain undisturbed. Dust was introduced to the mirrors manually and 4 cleaning methods were tested. These methods are listed from most to least effective:

  • Contact method (no cleaning solution): Optical brushes and cotton fiber swab
  • Contact method (non-alcoholic): Lens tissue with optical screen cleaner (altura)
  • Contact method (alcoholic): Cotton swabs and balls with rubbing alcohol
  • Non-contact method: Blower

Methods were evaluated for time, simplicity, and effectiveness. Overall, the optical mirror brush proved the simplest and most effective for dust mitigation on Mars.

 

Astrophotography of Celestial Bodies

Using the MDRS-14 telescope, we observed celestial bodies to investigate the effect of various filters. Calibration and stacking of images was performed with AstroImageJ. Procedures were implemented to account for weather and atmospheric distortion. These methods include choosing the best fits file for each filter prior to calibrating and stacking as well as repeating observations for celestial bodies. The Discovery object observations planned were scrapped due to weather.

Observations conducted at MDRS included:

  • M32
  • NGC 7318
  • NGC 1068
  • Little Dumbbell Nebula
  • Whirlpool Galaxy
  • M40
  • NGC 4258

Celestial bodies observed had two images generated: one composed of the Johnson-Cousins filter set (B, V, R) and the other composed of a generic filter set (Generic R, Generic V, Generic B). In addition to filters used, the noticeable differences in both images depended on the size and brightness of the object. An example is provided:

                Whirlpool Galaxy (Color Image and Generic Color Image)

Using a set of generic filters alters the appearance of a celestial body from its color as the filters are not a single color. Generic filters made images brighter as opposed to the Johnson-Cousin set, but generic images tend to skew the quality of the image. Future work will test a wider range of celestial bodies with distinct characteristics and a wider variety of filters.

 

Remediation of Mars Regolith

This investigation consisted of regolith samples inoculated by cyanobacteria to examine mineralogical changes through primary and auto-succession. The intent was to take biologically inert regolith and transform it into substrate for food production. Regolith characteristics of interest were clumping, wettability, and chemical and textural changes. Four samples of regolith were collected during EVA missions. The cyanobacteria used in this study was Anabaena cylindrica.

Daily measurements of cellular density were taken to measure population variations. Initial density was 1.78 x 105 cells/mL, an order of magnitude less than laboratory cellular density values. There was a significant change in algal color during transportation, which indicated a decrease in chlorophyll a and cell death. Low cell count and color change likely occurred due to lack of light and low temperature exposure. Cellular revitalization would have exceeded mission duration, so initial counts were taken and regolith samples were immediately inoculated. Three groups for each regolith sample were tested:

9 mL of regolith, 3 mL of media, and 1 mL of A. cylindrica

9 mL of regolith and 1 mL of A. cylindrica

9 mL of regolith (control)

After four days, no viable A. cylindrica were viewed in the samples. A. cylindrica did not survive the inoculation process, due to low initial cell count and continued exposure to temperatures below 15°C.

Upon completion of the Mars analog mission, follow up assessments will be made by using Electron Dispersive Spectroscopy (EDS) and Scanning Electron Microscopy (SEM) to identify changes in the regolith. We investigated the properties of the regolith as compared to controls to observe the effects of A. cylindrica. Though this study did not result in an observable growth or decay in cyanobacteria population, we were able to investigate the regolith’s clumping, texture, and dryness. Further analysis will be completed back at Florida Tech.

 

Chemical and Mineralogical Composition of the MDRS Site

This research used collected samples from the MDRS region to determine chemical and mineralogical compositions of regolith using X-Ray Diffraction (XRD) and X-Ray Fluorescence (XRF) analysis. Through small samples of regolith, we can infer the mineralogy, composition, and grade of the surrounding region.

The following steps have been completed for Crew 219’s mission:

  • Collected samples at 13 sites in the greater MDRS region and marked with GPS points.
  • Dried in an oven at 100 C0 and cleaned of impurities and plant roots. The samples were then sifted to two different sizes: 60m and 5m.
  • The samples were placed in special containers for shipment.
  • Run XRD and XRF analysis. This will take place in the geochemistry labs at Florida Tech and Ball State University.
  • Generation of a GIS map of the mineralogical composition of the site for future crews to use.

 

Protocols for the Discovery of Life on Mars

Crewed expeditions to Mars will need methods to identify and characterize extraterrestrial biology. Given the persistence of water on Mars, it is possible that life has or may exist on the surface. Our research focused on three categories of samples collected:

  • Known sources of microbial life (i.e. standing water, lichen, etc.)
  • Fossilized invertebrates (i.e. gryphea) as a proxy for extinct life
  • Random samples

Samples were photographed and collected for further study using fractal analysis, a possible method in the identification of extraterrestrial life. Previous work has demonstrated that fractals are an indicator of life on a microscopic and macroscopic scale. Using fractal patterns instead of chemical signatures allows us to identify non-standard biology on other planets. We took macroscopic and microscopic images of the types of samples listed above. Using FrAn, a Python program, we will analyze images for their fractal dimension or “D” value (Azua-Bustos and Vega-Martinez 2013).  This analysis will be performed upon return.

Future work will use images taken by our UAV and processed in FrAn. Using a UAV to identify areas with a greater “D” value can prioritize EVA sites as potential habitats, allowing astronauts to focus on the most promising locations.

 

Recommended Standard Operating Procedures and Inventories

Crew 219 tested procedures and checklists developed by Crew 205 (IESL), designed to improve crew efficacy. These procedures focused on improved performance for EVAs, tasks for Crew Engineers, HSOs, and team leaders. These task sheets were printed and laminated prior to rotation and will be handed to the assistant director upon completion of the mission. They will also be available digitally as a collection of appendices.

 

Recommended Update to Pre-Mission HSO Checklist Rationale

Crew 219’s HSO used his extensive safety and human-factors background to make a pointed re-evaluation of the HSO Pre-Mission Checklist, as included in the mission appendices.  The rationale behind these suggestions are based on efficiency and ergonomics of safety systems inspection and inventories, and bolster risk analysis and mitigation.

Mission description and outcome:

MDRS 218 “The Next Giant Leap” is the third all-Purdue crew at MDRS. This mission encountered different challenges than my previous two experiences, with snow and cold keeping the crew indoors for the first 5 sols and making EVAs much more difficult. The logistics of mission preparation were also different, with two crewmembers being unable to participate to preliminary meetings in person. However, the crew reacted very positively to the adversities, creating strong bonds and always giving each other support in every aspect of the mission. Despite the difficulties, all crewmembers performed to very high standards and provided good work on their research projects, as well as support to projects of the other crewmembers. The morale was always high and is visible throughout our mission pictures, up to the very last day. Even challenges like frozen pipes who forced us to use an alternative pump and carry water upstairs in a chain of pots and containers was experienced like a bonding activity. The research described below touched many aspects of human exploration of Mars, including analysis of outdoor features such as underground structure, weather, and radio emissions, and studies of human factors and the importance of environmental and operational comfort. The crew was also involved in astronomy and outreach through social media, and one of their sol was filmed to be featured in inspirational videos.

As commander, I am extremely proud of this crew, which faced adversities with flexibility and patience, and was capable to keep the highest level of fidelity and realism. The crew properly followed safety and research protocols, performed as a tight group, and found an appropriate mix of research activities and personal time, especially when the weather conditions forced us to review some of our goals. The pace kept throughout the mission was also challenging, ranging from slow days in the beginning, where our research activities were limited by the lack of EVAs which were necessary for many of our projects, to days with double EVAs, where the crew performed at very high level of quality and effort. As described in the rest of this summary, the crew collected useful and interesting data during their time at MDRS and has plans for use of the data after the completion of the mission, as well as ideas for laying foundations for further collaboration of Purdue crews with the MDRS program.

 

Summary of Extra Vehicular Activities (EVA)

After being trained in the use of rovers and in the safety protocols for EVA, the crew had twelve excursions during rotation 218, two of which being traditional short EVA to Marble Ritual, and the others being mainly along Cow Dung Rd because of the situation of the roads when covered in snow. Therefore, the EVAs were in areas in the Morrison Formation and Dakota Sandstone. The EVA served seven research projects: seismometric analysis of subsurface, radio measurements, collection of geological samples, autonomy for crew EVA, analysis of biometrics, meteorological observation and evaluation of EMU suits. The crew optimized the time on the field, limiting the driving time to less than 15-30% of the entire EVA duration.

Summary of GreenHab Activities

Crew GreenHab Officer: Dr. Jonathan R. Buzan

The state of the GreenHab is in excellent condition. Snow peas have struggled during rotation, and the strawberries were eaten by a Martian Field Rodent (caught and released). However, the tomato plants, and cucumber have grown considerably, and the cucumber has flowered. We had nearly daily harvests, regular rosemary bread (until we ran out of flour), spices for sauces and curries, and a large salad for 8 people on December 25th. The GreenHab was multi-functional, providing not only food, but a sense of calm and peace in a small habitat building surrounded by a sea of red and snow-white landscape. Overall, the GreenHab was a great place to learn about taking care of multiple plants and is an excellent opportunity to harvest fresh vegetables.

 

Science Summary

We had 12 separate projects that covered a range of topics. The vast majority were EVA related and were not started until after the first week due to weather related EVA cancellations. The major indoor project evaluated the temperature in a single stateroom for stressful conditions. The EVA projects measured spatial satellite radio strength, rock sampling of surface and seismic mapping of subsurface stratigraphy, real-time measurements of human bio-physiology, EVA suit stressors, field maintenance, decision making, and weather observations. Overall, each project uniquely highlighted each crewmember’s strengths, and brought light to necessity of bringing humans to the surface of Mars for both scientific and engineering related research.

 

Research Projects:

Title: Decision Making in support of autonomy for crew EVAs

Author(s): Cesare Guariniello

Description, activities, and results: Continuing a research project started last year, during EVAs events have been suggested to the crew, which had to decide how to act following disruptions or injuries, loss of communication, or environmental difficulties. The crew had to decide whether to continue the EVA, modify the primary objective, proceed to secondary objective, or abort the excursion based on safety of the crew, current status of the mission, achieved partial goals, and potential further acquisition of data. Due to the weather conditions, most EVAs had similar destinations, length, and objectives, therefore only a couple of scenarios have been analyzed. While most situations have an obvious “right answer”, such as major injuries, some of the grey areas are more difficult. Even a small disruption when three astronauts are in EVA with two rovers might require two of them to separate from the third one, which can cause safety issues.

Title: Mars surface weather

Author(s): Jonathan Buzan

Description, activities, and results: Martian weather observation and prediction are crucial components for evaluating evolving EVA conditions and overall mission safety for a human crew on the surface of the planet. This project took regular measurements during EVAs. 1) Dr. Jonathan Buzan trained crew members in three critical observations for Martian weather prediction: 1) Observe visibility in the four cardinal directions, determining viewing distance; 2) Vertical observations of cloud cover, type, cloud deck height, and visibility; 3) In-situ temperature, humidity, luminosity, and wind measurements were taken. All of these observations become the baseline for the development of weather station instrumentation, and eventually, localized weather predictions. Most notable aspect of field operations was that the weather changed regularly and quickly, which highlights the importance of trained EVA observations and prediction of weather on Mars.

Title: Subsurface structure on Mars

Author(s): Pat Pesa

Description, activities, and results: The goal of the project was to demonstrate the use of instrumentation for structural analysis of potential locations for building on Mars. Several sites in the MDRS area were chosen based on having different stratigraphic layers and were analyzed using seismometric measurements to determine shallow subsurface rock structure. In-situ procedure was setting out a line of geophones to record data after small impacts gathering information on how vibration waves travel through the sub-surface. After the mission concludes the data will be further analyzed at Purdue with professor Dr. Doug Schmidtt. Applications of this data will be better understanding of non-invasive structural testing of Martian surface for building and development for a sustained human presence.

Figure 3. Commander Cesare Guariniello and Crew Journalist Ben Durkee stand on the side of the seismometric sensors, while Crew Geologist Pat Pesa is ready to hit a metal plate with a hammer to generate seismic waves for his experiment of structural analysis of subsurface.

Title: Detecting radio signal strength

Author(s): Ben Durkee

Description, activities, and results: Radiological data was collected on the band of 436 MHz to 438 MHz. Surveys were done in various areas, including directly around the Hab, Cow Dung Rd, Galileo Rd, Kissing Camel Ridge, near White Moon, and more. Preliminary data processing has occurred, and more work is necessary to create the final heatmap of radio signal strength around MDRS

Title: EVA workload analysis

Author(s): Shefali Rana

Description, activities, and results: Feedback was collected from crew for long and short duration EVAs. Variation in score was observed for the exploratory EVAs conducted over a shorter distance versus ones for longer duration where heavier equipment was used for conducting the experiment. Different indicators will be analyzed to identify areas of larger discomfort.

Title: EMU (Extravehicular Mobility Unit) ergonomic assessment

Author(s): Shefali Rana

Description, activities, and results: EMU comfort parameters were scored by the crew for the two suits. There was a difference in score of comfort and ease of egress/ ingress between the two suits (light exploration suit and heavy two-piece suits). Scores also varied among the crew for what concerns ergonomics and ease of use.

Figure 4. Crew Engineer Luz Ma Agudelo is taking weather observations, while commander Cesare Guariniello points towards North. The ease of donning and using EVA suits was evaluated by the crew after each EVA

Title: Environmental Stresses over MDRS habitat and Crew Members and projection over Martian Terrain Author(s): LuzMa Agudelo

Description, activities, and results: Intending to understand the environmental conditions over Mars Terrain and design habitat structures and instruments that increase the human physical and mental capability, weather observations were performed, and data was collected over the MDRS terrain during Extra-Vehicular Activity (project no. 2). Data was also collected inside the habitat regarding temperature, humidity, wind, and radiation. Preliminary results on the crew engineer bedroom showed the nighttime temperatures with the door close surpassing the threshold of 26.6°C, considered the lower limit for human thermal heat stress, and a nighttime temperature average of 17°C with the door open.

Title: Messier and other space objects for outreach

Author(s): Cesare Guariniello

Description, activities, and results: The rotation saw only two days of clear skies. I managed to perform one day of Solar observations at the Elon Musk observatory, where the Sun did not show any spot or prominence, and one night where M42 (Orion Nebula) and M31 (Andromeda Galaxy) were observed and imaged in the robotic observatory. More observations have been submitted and will be processed after the end of the mission.

Title: Reliability and maintenance

Author(s): Shefali Rana

Description, activities, and results: Reliability of both the habitat structure and the EVA equipment is essential for safety. All equipment has to be installed, maintained and repaired on Mars by the crew and they have to be self-sufficient. For example, the habitat had a failure of the water pump pumping up the water to the tank for daily use. Repair procedure was initiated by crew Engineer. In this project, we simulated failure modes / malfunction of radio and rover during EVAs. Response of affected crew member and adherence / success of repair procedure was studied. This will be used to suggest operational protocols for failure scenarios.

Title: Medical readings in preparation for future crew-wide project

Author(s): Cesare Guariniello

Description, activities, and results: Crew commander wore a Zephyr sensor to monitor heart rate, breathing rate, body temperature, and level of activity 24/7 for three days during the mission. Data will be downloaded and analyzed after the mission, to evaluate areas and times of intense effort, and level of comfort and rest at night. The research project, in collaboration with prof. Barrett Caldwell at Purdue, will be extended to full crews in the future.

Title: Collection of clay and shale samples

Author(s): Cesare Guariniello

Description, activities, and results: Six samples have been collected for study in laboratory at Purdue. The samples will be evaluated for water content and geotechnical properties. Snow coverage did not allow for further collection.

Title: Media and outreach

Author(s): Ben Durkee

Description, activities, and results: @PurdueMDRS on Facebook & Instagram have been updated with pictures and progress updates every other sol. The posts and pictures are unique from each other and from the journalist reports and photos to make sure the audience is not receiving repeat content from all media. Video of Christmas celebrations needs final editing touches before being uploaded once back in regions of more reliable wi-fi.

In-situ Fluorescent Mineral Prospecting in a Martian Environment – Mike Lawson

Martian colonists will have to exploit local resources to survive and thrive on Mars.  UV searches can identify possible sources of rare-earth ores, radioactive ores and other useful minerals, such as industrial gemstones for cutting, polishing and abrasive processes.

Traditional rock sampling, either by chipping rock faces or cone and quartering (alluvial gravel) would net only small samples (kilogram or smaller scale).  A large scale survey would take many EVAs.  An in-situ UV search of a rock-face or a gravel deposit can rapidly scan many tons of material in a matter of minutes.  If a target “lights up,” it could then be sampled for further analysis in the Hab.

 

For this project, a portable 6 watt Analytikea Model UVL-48 ultraviolet light source in shortwave UV mode was utilized.  Two key terrain types were favored for the UV survey:  rock faces in cliffs or canyons and alluvial gravel deposits.  The former present an opportunity to rapidly scan multiple layers of rock and identify target-rich epochs in the Martian geologic history.  The alluvial deposit survey capitalizes on Martian erosive forces self-selecting out “harder” materials of interest (in Mohs scale context), such as industrial gemstones.  Four target areas were planned to be selected based on imagery reconnaissance, two rock faces, and two alluvial deposits.  Target priority was to be for ease of access to minimize travel risk during the EVAs.

 

To reduce the risk factor, only two EVAs were conducted for this project.  A morning EVA identified a safe travel route and potential survey site at Robert’s Rock Garden.  That evening, a second EVA was undertaken in partial sim (flight suits only) with permission of the Mission Director for safer nighttime operation.

 

Project status: Samples collected in the field were analyzed in the Science Dome, and a paper detailing the results of the UV survey will be written and submitted to the Mars Society after the completion of the mission.

 

Documentary Film – Evgenia Alexandrova

This project was to capture footage for a one-hour film in the style of a “poetic documentary.”  It was not to be a pure factual coverage of the crew’s MDRS experience with a linear narration.  Rather, questions to be explored included:  What is behind our dream for space?  What are we trying to learn through learning about space? Our future?  Or actually is it about our past, and are we looking for understanding about where we come from and where do we belong?

 

The first years of Mars colonization will hardly be easy for humans: confined space, dehydrated food, heavy spacesuits, no green color of nature, and missing home.  There will be not much intimacy, but there may be solitude.  Still we are driven by some dream, instinct, or curiosity to explore beyond.  One aspect of the film is to capture the evolution of the emotional state of the crew members.

 

Filming was undertaken every day during working hours, meals, spare time, and evenings, as one could never predict when something interesting was going to happen.  Several EVAs also captured the landscape and activities of team members.  Those who agreed to be filmed during an EVA were equipped with a small microphone inside their spacesuit.  Additionally, each crew member participated in a 40-minutes interview, and release forms were obtained from all crew members who were filmed.

 

Project status: All desired film footage was captured. 

 

Human Performance & Analog Mission Evaluation of Environmental Stressors via Behavioral Health Scales – Rich Whittle

Mars analog astronauts undergo a rigorous selection and training process to ensure crew cohesion and mission success.  However, even the healthiest, strongest individuals may face psychological challenges due to various stressors in extreme or abnormal environments. Examples of these stressors include isolation, confinement, close living quarters, monotony of food, delayed communication with ground control, time pressure, scientific or engineering failures, sleep difficulties, fatigue, etc.  In our effort to further human space exploration in a safe and effective way, we must thoroughly understand and protect the psychological and physiological well-being of crew, before, during, and after the space analog mission.

 

This project aimed to study crew member behavioral traits, including anxiety and depression levels, before, during, and after the mission using standard questionnaires at several intervals. This would allow us to better understand psychological well-being in response to known and unknown environmental stressors. This project further aimed to study the correlation between crew anxiety and depression levels and the possibility of a “third quarter phenomena” (TQP), whereby the first quarter of the mission may be characterized by crew excitement or anxiety, the second quarter by boredom and depression, and the third quarter by increased emotional outbursts. An addition to the study was to examine basic physiological changes in subjects over the course of the short duration analog mission to explore transient changes.

 

Five surveys were administered at Sol 1, 5, 10, and mission conclusion prior to departure from MDRS.  These surveys included PANAS (Positive and Negative Affect Schedule), POMS (Profile of Mood States), Sleep Quality Survey, ICE-Q (Isolated and Confined Environments Questionnaire), and PsychScale.

 

All crew members were contacted prior to mission to receive information and confirm if they would agree to participate.  Once on station, all crew members signed a form detailing the process of the research, any risks, and their consent to participate.  Note: This research was not for clinical findings, but for research only, with the research approved by the Texas A & M University Office of Research and Compliance.

 

Project status:  As of this summary, three-quarters of the surveys were collected, with the final one to be collected prior to departure.  The surveys will then be analyzed once they have returned to Texas A & M University.  

 

Mars Society and MDRS Educational Materials – Michael Ho

This project was to gather material to spread awareness of The Mars Society objectives and the Mars Desert Research Station by developing materials for a public presentation.  Activities included filming crew member self-introductions; recording the experience of maintaining physical and mental well-being living in a confined space with strangers for 14 days; an introduction to the physical structure and utilities of MDRS; a description of meals, water and energy resources, and waste conservation practices at MDRS; EVA procedures; and capturing drone video footage of MDRS, surrounding desert features, and EVAs on rovers.  Each crew member signed a written consent to be filmed for this project.  Additionally, taking pictures and observing celestial objects through telescopes in the Musk Observatory was undertaken in the role of Crew Astronomer, as was maintaining the GreenHab as the GreenHab Officer.

 

Project status: All desired material was gathered. Crew Astronomer and GreenHab Officer duties completed.

 

In-situ Resource Utilization for Medical Applications – Rich Whittle and Andrew Kennedy

This was a continuation of a Crew 215 project to collect gypsum samples to produce Plaster of Paris for application in medical interventions stemming from splinting to preliminary dental impressions.  This project required EVAs to collect and return materials from the field.  Three different ratios of water-to-gypsum were tested to conduct strength tests on the samples.

 

Project status: Using the best ratio of two parts gypsum to one part water, a plaster splint was created as proof of concept.

 

MDRS Communications – Marc Levesque

The current MDRS radio communication system of GMRS (UHF) handheld radios with an output of 2 watts limits how far EVA teams can communicate with the Hab.  A system utilizing VHF frequencies would greatly expand the range of radio communications.  Such a system would include handheld radios with 5 watt output and a solar-powered repeater with antenna located at an optimal site.  The design of this system would be a test bed for similar systems that could be deployed on Mars.

 

Viewshed analyses of various high points around the MDRS using geographic information system (GIS) software were undertaken, followed by EVAs to confirm the effectiveness and accessibility of these sites.  From these, it was determined that the summit of the North Ridge provided the widest radio coverage for those areas potentially explored by MDRS crews.  During an EVA, a team found an excellent site on the summit for a repeater location with direct line of sight to the Hab and confirmed the potential wide area radio coverage.  The team also mapped an accessible route, so that a future EVA (or non-sim work party) could carry the necessary components to the repeater site for installation.

An additional communications project attempted an amateur radio contact with the International Space Station (ISS) when its orbit passed directly over the MDRS.  This utilized a mobile radio in the Crew Commander’s personal vehicle set up in cross-band mode to allow the contact attempt to be accomplished from inside the Hab via a handheld radio.  The project required two short EVAs to set up and turn off the vehicle’s radio.  Crew members Levesque (W5MTS) and Lawson (KN4WOK), FCC licensed amateur radio operators, undertook the contact attempt.

 

Project status:  An optimal radio repeater site was identified for an expanded communications system.  If such a system is desired by The Mars Society, further research could be undertaken to determine the most suitable components for the repeater and handheld radios.  Should the project be implemented, The Mars Society would obtain an FCC license for VHF/UHF commercial frequencies that is available for non-profit and educational organizations and would provide the MDRS with its own unique frequencies. 

 

Contact with ISS was not made, most likely due to no astronaut operating the onboard amateur radio at the time the ISS was passing MDRS overhead.

 

Media visit

A production crew from Al Roker Entertainment spent a mid-mission sol with our crew to film one episode of a planned six-part science series to be aired in 2020.  During their visit, they filmed the area around the MDRS and its facilities inside and out, interviewed the crew as a group and a few individually, and filmed an EVA.  Our crew accommodated their requests in good spirits while maintaining sim.

 

Crew Commander Supplemental Note:

The selection of Crew 216 composition is to be commended, as the team worked extremely well together.  All members adapted in good form to conditions at MDRS and went above and beyond to complete station tasks and support other crew member’s projects, tasks, and activities.  As Crew Commander, I could not have asked for a better complement of bright, talented, creative, and enthusiastic individuals.  Given the steep learning curve that all members, including the Crew Commander, faced in their initial experience with station operations and protocols, I feel all performed exceptionally during the MDRS mission and are to be commended for their efforts.

Mission Status: Active
Sol Activity Summary: After ascertaining that Curiosity rover was operational (it was) our approved EVA for this Sol saw us returning to the micrometeorite sample grid in the stream wash at MM5 (518462E 4248949N). There, Guy, Larissa and Steve collected 30 samples before returning to the hab for lunch. 40% of the plots have now been sampled. During this time, gypsum samples collected from the White Moon location (517724E 4254500N) were begun to be cleaned and weighed in preparation for experimentation. This continued through the afternoon where samples from the micrometeorite grid were added to those being processed and packaged. Despite a rehearsal, construction in the hab caused a postponement of the disabled Marstronaut evacuation during the evening engineering EVA and, consequently, a ‘picnic’ dinner was held in the Green Hab.
Look Ahead Plan: Planning an EVA to MM5 (518462E 4248949N) to resume collection of micrometeorite samples and a demonstration of returning a disabled astronaut into the hab during the afternoon engineering EVA that had been postponed from the previous sol. See EVA requests. Continue monitoring of psycho-social stressors.

Crew 213 Mission Summary 24-May-2019

Crew 213 Mission Summary 24-May-2019

This course was our largest and most extensive iteration of our combined medicine and engineering education program. It went extremely well. Our crew enjoyed the simulations and clearly learned a lot about medicine and engineering as it relates to spaceflight.We continue to be grateful to the Mars Society for the opportunity to use this facility and all the resources it offers in our educational efforts. The major challenges we encountered were unpredictability with weather and managing a larger than normal number of students. The media team was an asset to our course and assisted us with arranging lighting and effects for our simulations.

As has been typical of our missions the daily EVA scenarios were handled safely and effectively and the emergency simulations were coupled with debriefs to ensure effective transfer of each learning objective. The feedback received from the crew both informally and through our own feedback process indicated a high level of enjoyment, respect for the facility, the course, and the challenges of a mission to Mars.

Our experience teaching doctors in previous versions of this course have lead us to a robust didactic, simulation, and discussion based curriculum. The landscape and the difficulties of living in the habitat are well known to us so there were few additional surprises. However, the weather was uncommonly rainy which forced us to amend our day to day operations on a near continuous basis. In the future, we will plan for back up activities to keep students engaged even when the weather precludes outside activities.

As this is the third time we’ve incorporated research projects into our curriculum, it has become a relatively routine part of our instruction. The crew was very receptive as were outside parties and we are looking forward to expanding this work in future missions. Our research is primarily focused on habitability, rapid iterative design, and feedback from task saturated personnel. We hope to present this at future meetings and continue to solicit more projects that can benefit from our unique population of medical professionals. Our projects for this year included a training and testing session of just in time training for ultrasound guided nerve blocks.

As always the realism of the EVA landscape is the most impressive feature of the MDRS site. The habitat facilities, EVA suits, and food supplies are well suited to the experience, however we have noticed a need for maintenance in both the habitat and space suits. Thank you for the continued opportunity to work with you on this project, we look forward to our continued collaboration.

Scientific Program           

 Cubelanders swarm (Carl-Henrik Dahlqvist)

Mars presents a dynamical environment that cannot be fully described by measures taken by a small number of probes. In order to get a more comprehensive view of Mars climate evolution, we proposed to rely on miniaturized landers, called CubeLanders that could be deployed on large strand of Mars surface via drones. Those landers would include several scientific instruments to characterize the environment and provide new insights into its evolution. In contrast with CubeSats which could deploy large solar panels and antennas, CubeLanders have a single solar panel covering one of their sides. We, therefore, have to limit as much as possible power consumption especially regarding the information transfer. We relied on an ultra-low power RF transceiver for short range communication and on the creation of a lander communication network to transfer the information to the deployment unit using only nearest neighbors.

The proposed concept has been tested during this rotation 211. The CubeLanders structure has been 3D printed while we used the Arduino platform for the electronic system. An algorithm has been developed in order to transmit the information via the CubeLanders network. It has been successfully tested in the Science Dome before a field experiment near the MDRS campus. The deployment of the Cubelanders have been made via drone using a new fully mechanical capture system composed of a fork attached to the drone and a rail system on the sides of each Cubelanders. The field experiment was a success even if the iron rich soil challenged the communication system.

 

Simultaneous location and mapping algorithm using a depth camera (Julien Amalaberque)

On Mars, the lack of a global positioning system and the unreliability of the magnetic north means that other solutions needs to be found to provide positioning and orientation. To do this for our drones, rovers and EVA suits, we decided to use an innovative algorithm called Simultaneous Location And Mapping, also already used with autonomous cars, with a depth camera (Intel RealSense D435i, released earlier this year). The basis used was RTabmap, an open-source implementation of the algorithm maintained by the University of Sherbrooke (Quebec, Canada). It works by creating a cloud of 3D points by extracting features from the image, and then by statistically computing the difference in position from the previous result.

The first step needed to be tweaked in order to allow feature extraction to work on a red, deserted environment which is very different from the classic urban use cases usually described in literature.

Once this was working well, another problem was that computing differences in position between images is an intensive task for a computer. Different image resolutions and frame-per-second settings had to be thoroughly tested to guarantee a reliable service. As a conclusion, the algorithm and the camera now work very well both inside the station and outside in the field. Its positioning ability can be used to automate the movements any kind of unmanned vehicle or as a tool for astronauts.

 

Study of Brownian motion of colloidale particles (Eléonore Lieffrig)

The Brownian motion of colloidal particles is the motion of tiny particles in a fluid at rest. Several experiences regarding to that field are currently running in the International Space Station, which offers the unique property of microgravity. The interest in studying the behavior of colloidal particles is that it finds applications in sectors such as environmental sciences, petrochemistry, chemistry and so on, including daily life. For example, we could be able to create a kind of plastics with better possibilities of recycling, or, a bit funnier, a vinaigrette that we would never have to shake for the components to be blended.

We first built hermetic enclosures containing colloidal particles in water. The chosen colloids had the property to absorb light at 540 nm et reemit it at 560 nm. Therefore, a fluorescence microscopy technology allowed us to observe the reemitted light by placing a camera on the trajectory of the beam. That way, we were able to get the course of many particles on camera and then track them one by one to verify certain properties we were expecting. For example, the motion of the colloids is independent with regards to gravity and the position distribution around the initial point is a gaussian curve.

Regarding the Musk observatory, the sun was very calm during our rotation, but we could observe little prominences on SOL 3. It was such a great opportunity to use this telescope.

 

Muon telescope (Maxime Bernard)

This project is based on the upgrading of a compact telescope based on small and gastight Glass Resistive Gas Chambers (“minigRPC”) build last year by Sophie Wuyckens and is aimed at performing a feasibility study of possible research on Mars geology. The first part of the project will be an improvement of the software used to to collect and analyse the data. The second part will be the eventual refinements we could perform on different parts of the detector to make sure the data we get are the most reliable possible. The third part will consist of the collection of in-field data at the MDRS, and its analysis. The goal will then be to make a study of the muon flux generated by interactions of primary cosmic rays and, if time allows to proceed to a radiography or tomography (3D) of the landscape (mountains, hills, etc.) of the Utah desert with “muography”. This technique is very interesting for planets exploration. For instance, we could radiograph Mars and characterize its interior and tell about the planet evolutionary state and history as well as even finding some places geologically well-adapted places for future colony implantation.

The idea of this year experiment was to compare the data I acquired right before coming to Mars with a brand new gaz mix in order to see if I could see a difference in the Muon count and therefore establish the efficiency of each detector to compare them and see if any modification were to be planed. Unfortunately, it appeared a problem occurred with the gaz mixed as I had way less Muons than expected. Despite a lot of effort to find the source of the problem, I could not find one.
It led me to the fact that it must be the gaz mix that was not efficient enough.

 

Martian constitution (Nathan Pechon)

Our research consisted in the drafting of a Martian constitution. As of today, no rules or legislation apply to Mars. However, law is necessary to organize the human society, as Martian missions are going to grow in scope.

We drafted it together with the crew because a text of such importance needs to gather all different opinions in order to be as democratic as possible. Nevertheless, Nathan played a central role in it. His project consisted in writing articles and submitting them to the crew for a vote. Of course, he took into consideration the crew’s opinions and he was very thankful for every idea coming from them.

Finally, we adopted 20 articles which are applicable on Mars. The Crew was very enthusiastic about debating them.

 

Geolocation with UWB antennas (Simon Collignon)

Here on Earth, GPS technology brought various tools to our society in a wide tech area. Up there on Mars, it might be as useful to implement GPS-like devices and keeping track of what’s going on in our new Martian civilization. Nowadays, there are different geolocation technologies for different purposes. In regard of the relatively small size of our facilities and the precise experiments undertaken, the most relevant setup is the one which maximize accuracy at the expense of the detection range. Using this configuration, we will be able to monitor near EVA, conducted by our astronauts and rovers.

The system required to meet those specifications is based on the emerging UWB (Ultra Wide Band) technology, brought by the IoT field. It will help us to develop an accurate geolocation system capable of tracking multiple devices of interest on our experiment site. In a further stage, the system could be extended for a wider UWB coverage.

 

In conclusion we achieved good results for tracking items in the science dome and in an outdoor environment. We collected a large amount of tracking data which will be further analyzed with more advanced post-processing technics. Moreover, we were able to visualize in real time the location of our tracked item during our experiments.

 

Sleep study (Benjamin Flasse)

A correct and regular sleep is essential for the recuperative power of the crew. For a long-term mission, the recuperative power is crucial for the preservation of the reflexes, the cognitive functions and the general health of the members of the crew. The harsh conditions of such a mission which are among others the stress, the confinement, the lack of privacy,  the seclusion and the closeness with the team 24 hours a day, could have a serious impact on the quality of the sleep and of the health of the members of the team.

This is why I analyzed the quality of sleep and the general health condition of the crew, through complete polysomnography (DREAM from MEDATEC), actimetry (E-tact from Bodycap), Critical Flicker Fusion Frequency (B-checkers), neuropsychometric tests (physiopad + MARES) and body parameters analysis (BiodyXpert).

Each morning and each night, each member of the crew went through a quick poll of tests enumerated here above, and 2 crew members were analyzed at night with a DREAM monitoring device. This machine allows to perform a complete polysomnography, they were wearing it every two nights. Since the DREAM analysis will be scored by a doctor in Belgium, I am not able to give any conclusion yet concerning the sleep quality. The other tests will continue in the few days following the mission, but some preliminary observations can be noted.

Firstly, every member of the crew can witness of an increasing fatigue during the mission, even so that naps had to be taken by some members. The weight and the measurements of the crew members does show a loose of body mass during the mission, even though this last one was probably affected by the unusual diet. The percentage of fat mass decreased while the percentage of muscle mass appeared to stay constant. Unsurprisingly, the stress and the brain fatigue appeared to be higher than in normal conditions. Some crew member experienced a water retention a few day after the beginning of the mission. No noticeable change was monitored concerning the cerebral arousal.

 

Spirulina as space food (Chloé Peduzzi)

As water is a limiting factor on Mars, lots of questions related to how to grow food on the Red Planet remain unsolved. On this purpose, current scientific researches focus on developing technologies to grow highly nutritive food requiring small amount of water. One possible option is spirulina! Indeed, those cyanobacteria are highly prospective for astronauts’ alimentation during future martian explorations. Not only can it be taken as a dietary supplement enriched in proteins, but it has also therapeutic properties. In that sense, we propose to establish a spirulina culture during our mission. The experiment will study the effect of space mission conditions on the culture system, including the small amount of space, materials and water available, the monitoring of the system and finally considering alternatives to improve the culture in such conditions.

10 spirulina cultures were prepared in 10 cell culture flasks. An artificial lightening made by white led was placed behind those culture flasks according to 2 different treatments (24h of light/day and 12h of light/day). The spirulina cultures were agitated manually each day. Cells were checked regularly using a microscope at various cultures’ stages. The cultures were observed at magnification 40X, 100X and 400X. Those observations confirmed the spiral shape of the spirulina’s trichomes. Resulting from HCO3 depletion through photosynthesis, the culture pH tended to rise continuously throughout the 2 weeks of simulation. This rise is positively correlated with the photosynthetic efficiency of the spirulina strain in the operational conditions of the experiment. The temperature variations throughout the 2 weeks of simulation were monitored continuously in the Science dome. The optimum temperature for spirulina growth is around 26°C-32°C (79F-90F) and should not exceed 38°C (100F). The contamination of the culture was monitored using axenicity tests in petri dishes. At the end of the 2 weeks of simulation, all spirulina cultures were harvested. Harvest occurred in the morning as temperature is the coolest and the proteins content (%) in the spirulina is the highest at this time of day. The filtration of spirulina cultures was easily accomplished by passing the culture through a PVC and polypropylene screen (40 microns in mesh size), using gravity as the driving force. The harvested spirulina was then washed with distilled water several times. Spirulina was carefully collected with a sterile spatula and stored on filter papers in petri dishes and was dried at 45°C during 5h. Finally, the wet and dry weight were measured for each of the 10 spirulina cultures. Further analyses will enable us to measure the protein content of the harvested spirulina.

 

Enhancing leguminous plant nutrition via mycorrhiza symbiosis in a Martian simulated environment ( Chloé Peduzzi)

As a one-way trip to Mars is estimated at 6 months at the shortest, a round-trip mission to the Red planet could last years. Therefore, setting up technologies to grow food in complete autonomy seems crucial. One main issue remains enhancing plant nutrition and increasing their resistance to stress and drought.

To elucidate that point, we propose to study beneficial mycorrhizal fungi connecting with plant roots and forming a network of fungal fibres, bringing water and nutrients to the plant. They support the plant for its entire life and improve yield. On one hand, we will study how this network develops in a Martian simulated soil. On the other hand, we will measure the effectiveness of the symbiosis with a leguminous plant in such conditions. Through this research, we aim to expand scientific knowledges on how Martian conditions affect symbiotic relationships between terrestrial organisms.

Seeds (bean + tomato) were soaked into water for 24h. Soil samples were collected in the Utah desert and were sieved. 16 treatments were repeated 4 times and placed into the GreenHab. The treatments were the followings: Irrigation (dry – Wet), Treatment (control – mycorrhiza – hydrogel – mycorrhiza + hydrogel) and Soil (50% Martian soil + 50% Compost – Compost). This part lasted 10 days. Then plants were harvested. Several crucial measures were taken. Further analyses with the harvested plants will enable us to quantify the mycorrhizal colonisation of the roots.

Mission Overview

Crew 211 is the 9th crew of the UCL to Mars project. UCL to Mars is a non-profit organization that sends researchers and students from the Université de Louvain to the Mars Desert Research Station. The objective of UCL to Mars is twofold, organize annual research stay at the MDRS and promote science to a younger audience through publication in the press and on social media as well as conferences in universities and schools. Both objectives have been fulfilled during this rotation 211, as we have had the opportunity to welcome schoolchildren on the 24th of April and a PBS crew on the 29th of April to increase awareness of the MDRS and its mission and more broadly to promote Science.  Beyond these visits, we conducted successfully nine scientific experiments in various fields of Sciences to answer concrete problems that future space travelers may encounter. Thanks to the variety of profiles we had in our team this year, we adopted an interdisciplinary approach to many problems, bringing added values for several experiments.
