Sol Summary – February 20th

Crew 293 Sol Summary Report 20-02-2024

Sol: 2

Summary Title: Slowly Settling Down

Author’s name: Marie Delaroche, Crew Commander

Mission Status: Nominal

Sol Activity Summary:

No EVAs were planned today, in order to continue setting up experiments in the Hab and other modules. After breakfast and a workout session prepared by our HSO, everyone got to work on their different tasks and experiments. The EchoFinder experiment has been set up in the Science Dome, and all location tracking anchors and most environmental sensors are in place. The crew has started taking cognitive assessments in different locations around the station; the data will then be correlated to environmental, location and physiological data as part of the Orbital Architecture study. Atmospheric instruments are also ready in the RAM, and have collected data during the night between Sol 1 and Sol 2.

Unfortunately, the solar observatory is still unusable, for the broken part of the telescope could not be replaced. This is a hard blow for our Crew Astronomer, but she is not letting herself be brought down, and is admirably contributing to other experiments she is responsible for.

Look Ahead Plan:

We are hoping for good weather conditions on Sol 3 to deploy the LOAC (Light Optical Aerosol Counter), MegaAres (designed for electric field measurements) at the location chosen during the first training EVA. We are also planning to do an EVA on Sol 4 to deploy a weather station and the Field Mill near the Hab.

Apart from Observatory operations, everything is looking good science-wise, which has given rise to the question of possibly having to deal with downtime in the next few Sols before other studies are launched (starting , something which had not been anticipated. I am confident that the crew will keep very busy, making the most of our time in this unique environment.

Anomalies in work: Solar observatory offline

Weather: Cloudy, light rain in the morning. High 56°F, Low

Crew Physical Status: Nominal

EVA: None

Reports to be filed: Sol Summary, Journalist’s Report, GreenHab Report, Operations Report, Photos (6-8 pics), EVA Request (1)

Support Requested:

As a way to reinforce the simulation, we would like to ask that Ben not specify the reason for his leaving the outpost (e.g. Going on a hike with Jules) if it is not necessary for the crew to know. We understand that for security reasons, the crew must know if Ben is not at the outpost, but we would like to keep communications between the crew and Mission Support as ‘in sim’ as possible.

Crew 293 Sol Summary Report 22-02-2024

Sol: 4

Summary Title: First clouds upon the Crew

Author’s name: Marie Delaroche, Crew Commander

Mission Status: Nominal

Sol Activity Summary:

This morning, the second EVA team tasked with installing the remaining atmospheric devices (the Field Mill and a weather station) left the station at 9:15. The team successfully installed a weather station which is now synchronized with a tablet inside the Hab. The data collected by the weather station will be used to determine how the measurements taken by the atmospheric instruments are influenced by wind speed, wind direction, humidity, etc.The rest of the EVA went smoothly, apart from a malfunction with the Field Mill.

One EVA crewmember started noticing an issue with the airflow of their suit as the EVA crew was approaching the airlock. Once inside, they felt their suit was no longer ventilated, and quickly asked the crew to take off their helmet, which they did immediately; sim was broken for safety purposes. The crewmember sat down and had difficulty breathing, as they had been breathing accumulated CO2. The entire crew reacted to the situation perfectly; we called Mission Support, and provided all the correct first aid elements. Mathurin checked their oximetry level, which was back to normal after they went back to the Hab. Once the situation was under control, Leo and Marie performed measurements on the ventilation battery and noticed that the battery level had dropped below 8V, after 3h30mins of use.

After re-reading previous emails between Mission Support and Crew 292, we realized the faulty suit (suit 6) was also reported to have battery issues, and that the battery had already been replaced before. We will make sure that the problem does not occur again by testing every suit (see Operations Report for details on the tests) to identify the ones that might be faulty.

The Crew spent the early afternoon resting after an eventful morning; we then spent time training with the AMI interface, and troubleshooting sensors.

Look Ahead Plan:

Tomorrow will be dedicated to various activities, most notably preparing videos for the schools linked to our outreach program, continuing the EchoFinder experiment, and troubleshooting hardware for Orbital Architecture.

An EVA to retrieve and fix the malfunctioning Field Mill is scheduled on Sol 6.

Journalist Report – February 22nd

SOL 4: First clouds upon the Crew

“Well, I must endure the presence of two or three caterpillars if I wish to become acquainted with the butterflies. It seems that they are very beautiful.” – The Little Prince, Antoine de Saint-Exupéry

Each morning when we wake up, we take what we call “Core Data”. These measurements are diverse: we weigh ourselves with an impedance meter, which records a large data spectrum such as weight, the detail of muscular weight and fat weight, an electrocardiogram, and others. We also record our tension and corporal temperature. Oximetry data are taken with an oximeter, placed at the finger’s tip. While we take a turn on each measurement device, we fill sleep questionnaires and time perception tests on our computers. The aim is to record these Core data all along the mission, to then provide them to researchers who conduct human factor studies. There are seven of us in the station, and we all must take all the measurements, so the recording takes a little bit of time. But, at this point, we are starting to get used to the procedure and to be very efficient: we managed to take all the measurements and to fill our questionnaires in less than 20 minutes!

After that, what’s better than another deployment EVA for the atmospheric instruments? Leo and Léa went on the EVA with Lise to deploy the last two instruments: a weather station and a field mill. Combined to LOAC and Mega Ares, deployed yesterday, these instruments will provide complete and precise data regarding the atmosphere and electric field. As part of the study, the CNRS researchers are interested in the earth’s desert. For us, participating in this study is interesting both for the scientific purpose and for the Martian life simulation, giving us opportunities to perform EVAs. This atmospheric physics’ experiment was brought to the station for several years by other ISAE-SUPAERO MDRS Crews, so researchers can record a large amount of data, necessary to their scientific publications. The deployment did not go as well as yesterday… Indeed, due to strong rays from the Sun on Mars, some of the devices’ electric cables melted… After three and a half hours of EVA, our astronauts came back to the station, even though the problem wasn’t solved.

Just before the end of re-pressurization of the airlock, one of the EVA team members noticed that their ventilation system was not working nominally. They quickly asked to take off their helmet, and the sim was broken for safety purposes. The accumulation of expired CO2 in their helmet caused them difficulty to breathe. The entire crew reacted to the situation perfectly; we called Mission Support and provided all the correct first aid. Mathurin checked their oximetry level, which was back to normal after their difficulties. Once the situation was under control, Leo and Marie performed measurements on the ventilation battery and noticed that the battery level had dropped below 9V… We will make sure that the problem does not occur again by testing every suit to identify the ones that might be faulty. Everything is back to normal, even though we were all a bit shaken, and the affected EVA team member felt much better during the afternoon.

During the afternoon, each Crew member worked on their experiments, Mathurin took care of the GreenHab and three astronauts performed the “Tilt” experiment, provided by the Neuroergonomy department of our school. The objective is to test the way we control a little shuttle which must pass obstacles, whether we are seated or laid down. We are testing two different points of view: third or first person. The aim is to study our perception and our orientation. Every Crew member will participate in this experiment, with one session per week and per person during the entire mission.

Questions, concerns and requests to Mission Support:

1) We were wondering if the water consumption sheet was functioning well. The sheet says that we used 3.8 gallons of water today, but after our calculations it should be a lot more (8L for dishes, at least 2L for hygiene, 10L at least for drinking so it should be at least 5 gallons…) I know that the sheet is not precise especially in the first few inches because of the geometry of the water tank, but isn’t this difference too big?

2) About yesterday’s question: what is an UPS? Is there a particular charging port that we should use in the science dome in order to not lose power during the power source switch? Could you explain more about how we could fix this problem? Thank you!
