Non-nominal systems: Power system, toilet, cabinet door under sink in Hab Action taken for non-nominal systems: See notes below for toilet and power system. The cabinet door might not be replaceable and if it isn’t we will go forage through the storage and see if there is an extra one in the cabinets for the ScienceDome Generator: Running from about 8 pm to 8 am. The generator was repaired on Thursday. The problem was the governor, which had lost a small plastic pin and as a result was unstable and the vibration of the engine was causing the surging. How crazy! We also needed the oil pressure sensor changed as it was faulty and we had the bushings replaced because they would have needed it soon. The technician was great and spent a lot of time showing us what things were that would commonly need replaced and how to replace them. I am very grateful to not have to worry every night about losing power! The oil pressure sensor will be mailed to us, but it is easy to replace. He did not have one with him. Solar— Nominal but we have had some cloudy days and since the generator currently won’t charge the batteries, we have had to use the generator more hours than normal. Solar— SOC Last 24 hours: Max 100 Min 44 Avg 65.9 Power system notes: I reprogramed the router so SOC can again be monitored remotely. Yay, me! Propane Reading, station tank – 73 % (all propane tanks were filled on Tuesday, the 27th, in anticipation of the storm Propane Reading, director tank— 83 % Propane Reading, intern tank— 81 % Propane Reading, generator— 73 % Ethanol Free Gasoline – 0 gallons Water (static tank) – 550 gallons Water in GreenHab – not noted gallons Water in ScienceDome: 0 gallons Water (Outpost tank) – 400 gallons Hab toilet tank emptied: See crew operations reports. On the 31st, I did flush the tank three times: 1. Filled it up and emptied what was left from the crew. It smelled. 2. Added a bottle of dishsoap and 5 gallons of hot water and emptied. 3. Filled it with fresh water and emptied, then added water and digester so it is usable. Each time I emptied it I still heard the glub, glub, meaning something is still wrong (how do you think my very professional words?) Sojourner rover used: yes Hours: not noted Beginning charge: 100 Ending charge: 100 Currently charging: yes Notes on rovers: nothing to report ATV’s Used: (Honda, 350.1, 350.2, 300): none Reason for use: n/a Oil Added? no ATV Fuel Used: 0 Gals # Hours the ATVs were Used today: 0 Notes on ATVs: Nothing to report HabCar used and why, where? Yes, to town CrewCar used and why, where? Yes, to town and to Grand Junction Luna used and why, where? No General notes and comments: Nothing to note Summary of internet: Nominal. HughesNet is being moved from my trailer and will be reinstalled in the Hab for crew use during simulation. Summary of suits and radios: See crew operations reports. EVA COMMS: Further changes to the COMMS system did not improve signal. They were: all radios with larger antenna, a rover mounted unit, and extending the repeater antenna by an additional eight feet. The decision was made to reinstall the system on the North Ridge, which was where it was when we tested it last season. Crew 271 did find a route to the top of the ridge, but it is going to take a huge effort to move it. We will do this as soon as we can, but it may be awhile before everything comes together. Campus wide inspection, if action taken, what and why? RAM exterior needs some repainting. Summary of general operations: It was so strange to have two external people on site in one week to work on systems. The crew mentioned this and I hadn’t thought about it, but I think I’m so lucky to have found people who can help when we really need it. We had the generator technician and then the electrician and the off-grid guy. Summary of Hab operations: One of the bean bag chairs broke and the crew threw it away although I had planned to send it back. One of the two doors on the kitchen cabinet under the sink boke and is scheduled to be repaired tomorrow. We noted several things needing attention during the two week period at the end of January when we have no crew. The electrician was also briefed on where and what we wanted done with outlets, etc. He will determine where electrical rewiring needs to be done. The off-grid guy studied the power system and we shall see if he can solve the mystery of why the generator and the inverters won’t get along. Summary of Outpost operations: General cleanup in preparation for upgrading deck. Summary of GreenHab operations: Supplemental light 10-2 pm. Summary of ScienceDome operations: Standing desk was returned from the Hab. ScienceDome Dual Split: on at 65 degrees overnight (when I remember). Summary of RAM operations: We have a lot of used oil to recycle. Summary of any observatory issues: Both observatories were used by Crew 271 and some issues were reported to Peter. Summary of health and safety issues: Nothing to report Questions, concerns, supplies needed and requests: Happy New Year and welcome to Donald Jacques, our new Site Manager, who arrived at MDRS this evening in his big black bus! Crew 271 Operations Report 26-12-2022 SOL: 8 Name of person filing report: Sergii Iakymov Non-nominal systems: Kitchen sink cabinet hinge, headset #3 Notes on non-nominal systems: 1) We inspected the malfunctioned sink hinge and found out that the hinge came off because wood around it was softened by moisture. We will have to put it back and use a small amount of silicon to compensate for the increased size of a hole due to softening. Please advise if this will be acceptable? 2) We also have found a root cause for moisture under the sink. There is no silicone between sink and countertop and water goes underneath if it accidently dropped on the countertop. We do recommend silicon after the mission is finished, so it has time to dry.

Action taken for non-nominal systems: We will be investigating tomorrow Generator: Running from about 8 pm to 8 am. We looked into some of the issues surrounding the autostart last weekend and as usual, the power system decided to seek revenge. The router is showing as SOC connect for the generator but the online data is only showing VDC. Sooooo…. We need to figure out which parts of the system need reprogrammed. ScienceDome Dual Split: on at 65 degrees overnight Solar— Nominal (see generator notes for some issues with the power system as a whole) Solar— SOC Last 24 hours: Max Min Avg not showing the way it is currently operating Propane Reading, station tank – filled Friday % Propane Reading, director tank— filled Friday % Propane Reading, intern tank— Filled Friday % Propane Reading, generator— Filled Friday % Ethanol Free Gasoline – 0 gallons Water (static tank) – 550 gallons Water in GreenHab – 200 gallons Water in ScienceDome: 0 gallons Water (Outpost tank) – 550 gallons Hab toilet tank emptied: Yes, it has been emptied every two days this week as there is a blockage.

Summary of suits and radios: See crew operations reports. Campus wide inspection, if action taken, what and why? Nothing to report Summary of general operations: Conduit work delayed Summary of Hab operations: As noted above the toilet has a problem that we need to investigate. I ordered a new humidifier for the upper deck. The one we had was not operational nor was it one I purchased. Summary of Outpost operations: I broke one half of the handle to the output on my trailer’s wastewater pipes because it was frozen. It is still usable. Sergii’s hot water to the bathroom froze last night. It’s been very cold for this early in the season. I’m also using my wall unit to supplement the heat in my house. Summary of GreenHab operations: Shade cloth was removed. Supplemental light 10-2 pm. Tomatoes all moved to the bed frame. We transplanted the ones from the herb garden into pots as they were not thriving. We removed some of the snow peas to do this, and I replanted snow peas in the herb garden. I thinned the carrots and we replanted microgreens in one of the two raised beds. We also replanted cilantro in clay pot bottoms as they grow better than way. Tomorrow I will clear out the cilantro pot and plant another microgreen. Summary of ScienceDome operations: Used all week for SWBU. I will be removing the broken microscopes and taking them to WA for replace. One of the teachers who was here for SWBU has donated a new microscope that I will pick up in SLC as soon as possible. Summary of RAM operations: Added a spark plug gap measuring device and a new ratchet handle to the tools.

Challenge Resolution Mechanisms in Isolated and Confined Space Analog
Mission Through Ethnographic Methods (Study 2)
Crew member: Andres Käosaar
Overall, the data gathering for the projects well very well – the members of Crew 271
patiently filled in my surveys and there seems to be no missing data points. Due to the
high cohesion and professionalism of the crew, there haven't been too many overtly
observable coping strategies or team challenge resolution mechanisms executed (don't
get me wrong – not that expressing those aspects is unprofessional, but we just haven't
had many problems to deal with), but there have been some instances that I've been
able to note down for further analysis. On the other hand, due to the individual profiles
of the Crew 271 members and the overall resemblance to a potential real long-duration
space exploration team (i.e., culturally and professionally diverse crew very interested in
human spaceflight), the data are good and the sample has high validity. Since I'm not
able to access all the data (the survey answers and post-mission interviews) before
leaving the station, I can't make any further conclusions, but I'm quite hopeful and
optimistic regarding the potential findings and conclusions from the studies.
Crew member: Helen Eifert
A location was selected north of the Hab for an experiment to measure drying trends of
a clay-rich and Mars-like surface over the course of the MDRS mission. The experiment
is supplemental to a series of desert field campaigns that assessed thermophysical
properties of different Mars-like environments and their associated drying trends. The
goal for this particular experiment was to observe the drying trends of a clay-rich
surface for a longer period of time following controlled wetting of the surface to
understand chemically bound water trends better. This contributes to the overall
understanding of how water may be retained, persevered, and detected on Mars.
The initial wetting of the experiment was conducted on Sol 4, 22 Dec 2022. The
immediate drying trends were measured for an additional two hours following saturation
of the surface on this first EVA using an ASD FieldSpec3. This data shows visible near-
infrared surface reflectance in order to better understand water molecules that may
become trapped in the chemical structure of clays and how long it can be retained.
Return EVAs were conducted on Sol 5, Sol 6, and Sol 9 for an additional two
measurements each day. On the last day of measurement, a dry sample was collected
from a nearby site to get initial water content and an additional sample was collected
from the experiment site, which still appeared damper than its surroundings. Due to
incoming rain, the observation period needed to end on Sol 9. The two samples
collected were returned to the Science Dome for loss on ignition analysis. Here, they
were baked at just over 100C to burn off any water. Weights were recorded before and
after to understand the water content of the samples and how close the experiment site
got to equilibrium with the dry sample. The spectral data was post processed and will be
plotted and analyzed upon return from MDRS to be used to supplement the findings of
prior field campaigns. This work is in preparation for publication in the late spring 2023.
Crew member: Cesare Guariniello
Three long-distance EVAs covered regions not visited before by Guariniello. Samples
were collected in the area of Barrainca Butte (black vesicular igneous rocks,
conglomerates, and light-colored mudstone), Candor Chasma (Summerville formation:
red mudstone and sandstone with cross-cutting gypsum veins), and Skyline Rim
(Dakota conglomeratic sandstone and Mancos Shale samples). Samples were weighted
and processed in the oven in the Science Dome, then weighted again to ascertain water
content. The samples will be shipped to Purdue University for further spectroscopic
analysis to identify geotechnical properties for ISRU via remote sensing. In particular,
spectra will be studied for indicators of water content and bulk size.
Crew member: Cesare Guariniello
Robotic Observatory: After adjusting the MDRS-14 telescope, multiple observations
were taken when the sky was clear. The most notable was M42 (Orion Nebula). Other
objects that were sampled are M1 (Crab Nebula), M3, M31 (Andromeda Galaxy), M97,
M101 (Pinwheel Nebula), Rosette Nebula, Barnard 33 (Horsehead Nebula). The
Astronomy Support will further work on the telescope focus.
Musk Observatory: The sky was hazy or cloudy on most sols. One observation of the
Sun was performed towards the end of the mission. This allowed the whole crew to
participate in a solar observation. One photo of a group of sunspots with visible umbrae
and penumbrae was captured and processed.
Module
Crew member: Alicyn Grete
The purpose of this project was to verify whether Martian analog crew members could
use an offline, self-assessed module, and locally reproducible 3D printed bone
simulation models to become confident and competent in performing external fixation
procedures to manage open tibial fractures in an austere environment without access to
specialist support from Mission Control. I hypothesized that the Tibial Fracture Fixation
Training Module would provide analog space crew members with the confidence and
competence necessary to teach themselves a new surgical skill. To test this hypothesis,
I conducted an observational study with participants from a Mars Society Desert
Research Station analog crew.
I began by obtaining consent from all participants at the beginning of the mission. The
first two days were spent having participants take a pre-learning confidence survey and
complete the training materials and video. Over the next four days, each participant
successfully completed a skills test, achieving a go ahead on each competence
objective and verifying their work with self-assessment photos. Afterwards, each
participant completed a post-learning survey and received a certificate and Medical
Makers memorabilia to commemorate their accomplishment.
From the surveys, all eight confidence variables showed a statistically significant
increase following simulation-based training (p values < 0.0290 and a change on the
Likert scale of 1 point or greater at the 95% confidence level). All procedure steps for
uniplanar external fixation were completed to standard by all six crew members, five of
them on the first try without practice on the equipment. These results suggest that my
hypothesis was correct: the Tibial Fracture Fixation Training Module can provide analog
space crew members with the confidence and competence necessary to teach
themselves a new surgical skill.
I will be submitting an abstract to present this research at the West African College of
Surgeons Conference in Togo this spring, and I am halfway done with an article draft to
submit to the Aerospace Medicine and Human Performance journal, the most used and
cited journal in the field of Aerospace Medicine. Additionally, I made a film
commemorating our experience at MDRS with tibial fracture fixation that depicted how a
Martian crew would respond to a tibial fracture occurring during an EVA.

During this season MDRS teams have encountered some issues with power systems of
the EVA suits. During Crew 271 all 11 EVA suits were inspected for their power
systems, and especially wiring connections, charging hardware, and rechargeable
batteries. The results of this inspection revealed the following:
1) All wiring was in working condition.
2) All charging hardware was in working condition and operating nominally.
3) There was a problem with the station generator, and there is a possibility it was
causing the previous problems with the suit batteries. After the generator was
fixed, no further problems were observed.
4) Four EVA suits were plugged into a power strip that had a loose connection with
the chargers. As a result, these suits were not charging to the top level of the
battery capacity. The power strip was replaced with a new one which provided a
solid connection with the chargers. This change allowed the suits to be charged
to the maximum battery capacity.
5) In order to measure battery level charge, crews have needed to use a multimeter
to measure voltage via charging ports or open backpacks. These actions are
wearing down suits components and increasing the risk for parts to be broken by
inexperienced crews. In order to avoid this happening it is recommended to
include into the suit systems a battery charge indicator next to the charging ports.
A second project evaluated MDRS power consumption at the request of Mission
Support by evaluating active station electrical devices. A spreadsheet of the station
components and power consumption was created and sent to Mission Support during
the last communications window.
Crew member: Marc Levesque
A new radio repeater for MDRS was installed in October 2022 west of the station on
Hab Ridge. Based on radio propagation analysis, this site was believed to provide radio
coverage between the Hab and EVAs teams throughout all the areas teams would
travel. During the first few missions this season, this turned out to not be the case, as
several communication gaps were discovered. Some of this was believed to result from
the numerous hills in the area that blocked receptions, while some were also likely due
to a lack of proper radio operation on the part of crew members.
To determine the major cause for the lack of communication in some areas, the project
undertook several steps. The first was to check the repeater’s battery status and overall
operation by opening the repeater shelter and conduct a visual inspection of the
equipment, all of which were in working order. The second step raised the repeater
antenna by attaching it to a six meter mast, which was then secured by new guy wires.
Communication checks were conducted during EVAs to determine the effectiveness of
the heightened antenna, but no significant improvement in reception to and from the
field was noted. A mag mount antenna was also used on a rover during one EVA to test
its effectiveness, but this was also found to be ineffective. A further task monitored the
battery drain on the handheld radios during EVAs to determine an appropriate
recharging interval.
Based on the results of this project, the following recommendations are made:
1. Move the repeater to a permanent site on North Ridge. This was the site of a test
project during Crew 265, during which a small repeater was established and
provided excellent radio communications between the Hab and most all EVA
areas. Permission to establish a permanent repeater on North Ridge will likely
require BLM approval, and if granted, would also require an arduous equipment
move during the fall 2023 work party, including the building of a new repeater
housing or enhancing the existing shelter, along with erecting a robust tower
structure for the antenna. Note: At the end of the mission, a possible route for
transporting the repeater equipment to a North Ridge site was located though a
field trip.
2. Consider re-establishing Communications Officer duties on each MDRS crew,
with those duties most likely assigned to the Crew Engineer. These tasks would
include instructing all crew members on the proper operation and care of the
handheld radios, monitoring radio battery consumption, and monitoring
recharging status to insure they are removed when they reach charged status.
This is important because batteries that are fully recharged and left on the
charger will cause rapid battery decline. Assigning a Communications Officer will
help ensure that this procedure is followed.Supplemental Operations Report 31-DEC 2022
