Crew 185’s First EVA
David Murray
Mission Status:
Sol Activity Summary: The crew woke up, ate breakfast together, and attached our patches to our flight suits. Then, with the help of the entire crew, Tibo donned the X-1 space suit and headed out with Arno and I, in EVA suits, to complete the daily engineering check. Immediately following this, Tibo changed into the EVA suit to join Ilaria and I for our first EVA. We walked for about 3 km and explored the surrounding terrain. When we returned, we continued our custom of eating meals as a team and sat down for lunch. Following our meal, I gave the crew a quick tour and summary of my research and work in the Greenhab. We then returned to the Hab to take part in John’s anesthesia training where we learned how to identify and anesthetize the sciatic nerve on a gel block with the help of ultrasound imaging.
Look Ahead Plan: We plan to go on our second EVA tomorrow. It should be the same as the first EVA but with different crew members.
Anomalies in work:  None
Weather: Sunny, warm
Crew Physical Status: Healthy
EVA: 3 km EVA with no vehicles to explore the surrounding terrain and get used to the EVA suits.
Reports to be file: None
Support Requested: None

Journalist Report – December 20th

[Sol 2]
The least we can say is that Crew 185 had a busy day at MDRS! We woke up this morning at 7am, had a breakfast of cereales and homemade bread and then, we put on our spacesuits to do our daily engineering check. For the occasion, Arno wore a simulation spacesuit from the Association Planète Mars (the French chapter of the Mars Society) and Thibault wore the X-1 spacesuit prototype. We filled the water tank and verified that the station is doing well. It is!
Then Thibault, David and Ilaria did a walking EVA around the hab, in the region of Pooh’s Corner. They evaluated the geological potential in the area for future experiments and they hid two objects for an orientation experiment that we will do tomorrow. They walked about two kilometers. The weather was pretty warm but they achieved all their objectives on time.
After a nice lunch (salad with an apple cider dressing and pasta with small bites of saussage with tomato sauce), we visited the Greenhab for David to explain us how it works and what experiements he runs there. Then, John explained us how to use an ultrasound machine to make an anesthisia of the popliteal area (the region behind the knee). We practiced on a gel model and we will try to do it again (on model) without his help in few days. He will monitor how successful we will be.
The weather changed during the afternoon. It is now very windy outside. Mars might be white tomorrow according to weather forecast. We will see!
Greetings from the Red Planet,
Thibault, ExO and spacesuit engineer for the Crew 185

Non-nominal systems:
– Spacesuit 3 : The ventilation system of spacesuit N°3 (mine) stopped during the engineering EVA. Back to the EVA room at 11:36am, I plugged the backpack but the DEL of the charger was still turned off. I meticulously moved the plug of the charger and the red DEL of the charger switched on.  At 2:30pm, I turned the ventilation system on and it was working properly. There is thus a faulty connection. I will open the backpack this evening to see whether or not a wire is badly connected to the outlet of the spacesuit.
– Spacesuit 4 : Back from the EVA at 1:25pm, while undressing her spacesuit, Ilaria pulled out the right ventilation tube of her backpack. I just had to plug it back into the spacesuit.

Our team started out as strangers, thrown together with nothing in common except a love for space and desire to test ourselves on the surface of Mars.  After months of intense long distance preparation and now, completing our two week mission together face to face, we have bonded as a team both personally and professionally to advance our shared love and drive of advancing the cause of human space exploration.


During our mission preparation, we assembled a set of research objectives playing off our respective strengths and keeping present the goal of simulating a Martian Mission as accurately as possible.  We faced numerous challenges and failures during our mission that threatened the successful completion of our goals, but through hard-work, troubleshooting and flexibility we completed our objectives and can return home with a successful mission behind us.


We hope that through this mission and future efforts we can move forward the goal of human exploration of space, and will now begin the next phase of our mission in taking our research and data back to external parties and in continuing the outreach process to utilize our experience to inspire greater enthusiasm for the possibilities of space travel in the general public and the next generation.

Summary of Research Completed:

Matryoshka EVAs

Evaluating the past habitability of Mars is a key science objective for the near future. Meeting this goal will involve innovation, exploration, and scientific enquiry across all levels of observations. At the MDRS, features analogous to those on Mars were characterized and utilized to further develop identification techniques of geological points of interest. Dunes and channel structures provided a test-bed for investigation of the geomorphological bodies found in Martian terrains


During our stay at MDRS, we highlighted the value of using four modes of geologic survey operating at increasingly fine scales. Analogous to the gradual down-scaling of a Matryoshka (Russian) doll, the four-phase sequence of study provides observations at a progressively smaller scale: satellite, drone, rover, and human (hand scale).


Under the expertise of the Department of Earth Science at the University of Oxford, eight sites were chosen for sample collection and return to Oxford for further geomorphological and geochemical analysis. This work was proposed by a team of undergraduate and research students with goals to not only conduct scientific research activity on the collections, but also use them for outreach purposes to inspire the next generation of analogue astronauts!

Fatigue Sleep Study

The crew underwent a two week fatigue study by following the Martian day, 40 minutes longer than an Earth day. For two weeks, they completed multiple surveys daily on their sleep, fatigue, and general wellbeing while shifting their sleep and wake times by 40 minutes each day.  The crew was able to manage the stresses associated with a Martian day despite the difficulties that are inherent in analogous missions.  There was an increase in short naps towards the end of the mission in order to satisfy the mission and scientific objectives.  This completes the crews MDRS portion of the Martian Circadian Study successfully.

In addition to surveys and sleep shifting, the crew had to complete multiple tests throughout the mission to measure their psychomotor vigilance, called a PVT (psychomotor vigilance test).  The tests are administered via an iPad so participants can access the test easily and complete it three times a daily (see photo).

(Figure 4: Commander Tom Horn starting his PVT test)



Crew 184 completed an important anesthesia task during the mission looking at the ability of astronauts to complete a nerve block of the lower leg. They used gel models created at the University of California, San Diego to place a needle above and below the simulated nerve located behind a knee.  The simulation looks at the ability of participants’ time to complete tasks in an emergency scenario.

Mars is an environment that requires strength training to keep astronauts healthy with minimal up-mass.  John Sczepaniak MD created an 18 pound medicine ball on Mars with minimal up mass (~600g).   A cycling machine was assembled at the station by crew 184 for health and fitness.  The cycle was donated to the Mars Society for use by future crews.

Communication Study

The question of how to effectively operate a human crewed mission with a lengthy time delay is a significant unsolved question in human spaceflight, and is one that analog space missions are uniquely suited to answer.  Previous human spaceflight experience has entailed close coordination and direction between the crew and Mission Control, future missions to Mars and other destinations will necessarily entail a whole new operations structure including new communication guidelines and devolving significant power away from Mission Control and to the crews themselves.  In order to simulate this our crew worked with an offsite scheduling team to direct our activities and with who we experimented with different communication methods, feedback techniques, and email time delays.

We experimented with various communication methods internally to the team via our ‘Bricks’ experiment.  With this we took symmetric sets of building blocks and experimented with building various structures with different crew teams and different time delays, from 0 to 15 minutes in 3 minute intervals.  Via trial and error our team learned how effective communication tools which were put in place throughout our mission.  They proved particularly effective during EVA where communication over VOX is difficult and several techniques were immediately applicable to aid in EVA coordination among the team.  Our team agreed that of all the lessons learned five in particular were critical, which are described below.

Five Takeaways:

  1. Give an overview of what task is trying to accomplish. This allows crew to fill in missing details and help connect the dots themselves
  2. Give an inventory of all supplies to be used during the task up front, and what each thing is being used for. This allows easy identification of mistakes if supplies are left over, and also allows crew to better understand their instructions.
  3. Agree on common descriptors for entire supply list to ensure accurate description, i.e. “4 pronged short rectangle”
  4. Establish a common orientation for the entire task at the beginning, then stick to it. This ensures proper placement of materials.
  5. Repeat all instructions twice. With unreliable radios this ensures momentary communication dropouts does not prevent critical information being relayed.  This is especially important for longer time delays where a missed word could result in a 30 minute delay.


(Figure 8: Josh Hunt listening to instructions to build a structure with a communication time delay.)


 CPR Techniques

The low gravity environment of Mars is likely to pose unusual challenges to a human settlement.  An example of this was posed to our crew as a challenge for us to solve during our mission.  How do you exert enough force on a patient to perform effective CPR when you have a significantly reduced body weight?  In order to simulate this in an Earth environment our crew was given our friendly CPR helper ‘Max’, a scale, and force targets in excess of their body weight that they had to achieve.  Each crewmember performed trial runs and various techniques under the supervision of our crew doctor, recording their results.  Of the various methods tried the three most effective were, 1)  Placing weights on the patient’s chest to effectively raise caregiver body weight during compressions, 2)  Having another crewmember assist in chest compressions, and 3)  Bracing crewmember on an overhead beam to provide additional resistance for compressions.

This is just one example of an esoteric problem presented by low gravity conditions, and there are sure to be more.  We found it interesting to discuss these scenarios and envision the challenges to be confronted by a Martian colony, many of which are sure to only be discovered once humans are already on Mars.
