Journalist Report – March 14th

SOL 26: This Is Not the End.

04:20 PM: Last day in the station. The entire crew is dismantling the final experiments, tidying up the station, and cleaning the modules… Robin, Erin, and I went out for the last EVA of the mission, which was partly organized by students from Mirepoix, to take down the atmospheric instruments. Everything went as planned—if not better—since we managed to pack up and bring back all the instruments in less than an hour!

Once everything was stored away, we found ourselves in a different station. Suitcases were scattered across the floor, and Célyan asked everyone to return the sensors from the Orbital Architecture experiment, as we wouldn’t be wearing them today. This morning, Meddi and Somaya tried once again to get the SUPAEROMOON rover to move, but without success. Still, the little machine’s wheels had touched the ground of our very own "Mars."

We completed our final cognitive tests and last questionnaires. In less than an hour, at 5:00 PM, we will break the simulation. In less than an hour, we will be free to run through the Utah desert—no longer Mars—to breathe fresh air, to see each other’s faces without the glass visors of our EVA suits.

Of course, the mission is not over. We still have a lot of data to transmit to researchers, documents to write explaining our experiments, and some experiments are still ongoing! This mission has been a scientific experience that we hope will prove useful, but one thing I am sure of is that it has been an incredibly enriching human experience.

It’s time. It is 5:00 PM, the time to open the door leading back to Earth.

7:17 PM : We stepped out, we ran, then we walked, then we climbed a mountain we had been seeing in the distance. It feels good to be free, to go wherever we want, without the constraints of space or time, without the limitations of our rovers’ batteries or our spacesuits’ oxygen supply.

The mission is not over, because we expect results to emerge, because we intend to pass on our experience to the next crew, because we plan to take it even further.

Supplemental Operations Report – 08Mar2025

[title Supplemental Operations Report -March 8th]
[category operations-report]

Date: 3/8/2025
Name of person filing report: David Steinhour
Reason for Report: Routine
Non-Nominal Systems:
Non-Nominal Systems: Crew car. Power system battery, invertors, generator. Robotic observatory. HAB outer shell.

Power system: "Solar: The battery bank does not hold charge when the sun is down and low on the horizon. Inverter Slave 1 and 2 went offline and did not restart, which limits us to 5kW when on solar.
Main generator has been monitored for oil leaks; minor leaks observed, need to add oil every 2-3 days. Generator is limited to 8kW, see previous reports for details.
Main generator:
1) Oil, oil filter changed on 2/26/2025.
2) Current hours – 8772.8"

Propane Readings: "Refilled 2/26/2025
Station Tank: 62%
Director Tank: 58%
Intern Tank: 79%
Generator Tank: 53%"

Water: "Hab Static Tank – 241.4 gallons
GreenHab – 121.5 gallons
Outpost tank – 390 gallons"

Rovers: "Sojourner rover used: No
Hours: 209.5
Beginning Charge: 100 %
Ending Charge: 100 %
Currently Charging: Yes
Notes on Rovers: None"

Cars: "Hab Car used and why, where: To Hanksville for supplies.
Crew Car used and why, where: No.
General notes and comments: Crew car driver’s side front ball joint is bad. Low oil pressure is most likely caused by a bad sensor (it does not change due to RPM or temperature like it should)."

Summary of Internet: Nominal
EVA suits and radios: "Suits: Nominal.
Comms: Nominal.
T-Echo EVA-link: Astro8 is malfunctioning and needs to be replaced."
Campus wide inspection, if action taken, what and why: Tunnel tarp was patched today 3/8 by crew on a mock-emergency EVA. Repair looks good.
Summary of Hab Operations: Small cracks in the wall of the Hab in the loft area are allowing cold air intrusion.
Summary of GreenHab Operations: Nominal
Summary of SciDome Operations: Nominal

EVA Report – March 11th

EVA #: 14

Author: Robin GORIUS (Crew engineer, EVA Leader)

Kissing camel study and remapping with a drone due to mistakes made today. Custom small robotic exploration rover photo shoot in front of the hab at the end of the EVA. ESA radar altimeter calibration device inspection as asked by mission support.

Start time: 09:33 AM

End time: 12:45 AM

Narrative: The crew drove to KCR W where we performed the photogrammetry nominally. We drove back to the station and arrived at 12:34AM. We had an issue with perseverance parking brake which didn’t hold the rover when parked at the station. We blocked the rover with rocks before mission support could fix the brake. After we took out a custom built exploration rover out of the airlock to take a picture of it. We quickly took pictures of the ESA radar altimeter calibration device before entering the airlock at 12:45AM and entered the station safely at 12:50AM

Destination: Kissing Camel Ridge W

Coordinates 518000 E, 4249500 N

EVA Participants: Célyan Ferret (HSO), Quentin Berlemont (Astronomer), Somaya Bennani (scientist) , Robin Gorius (Crew engineer and EVA leader)

Road(s) and routes per MDRS Map: Hwy 1575

Mode of travel: Driving to Kissing Camel Ridge W, walking in the area. Coming back to the station using the rovers.

Vehicles used: Curiosity and Perseverance

Curiosity: Start 100%, 300,5h/ End 89%, 300.7h

Perseverance: Start 100%, 310.0h/ End 86%, 310.4h

Sol Summary – March 11th

Crew 311 Sol Summary Report 11-03-2025

Sol: 23

Summary Title: The rover has landed

Author’s name: Erin Pougheon, Crew Commander

Mission Status: Nominal

Sol Activity Summary: This morning, 4 crew members performed an EVA at Kissing Camel Ridge. The aim was to find all checkpoints placed here the day before thanks to a 2D map. They were successful and while they were searching, Crew Scientist was taking pictures again of the area to retry to create the 3D map for tomorrow’s EVA. Meanwhile, in the station, we started to organize how to uninstall and pack the experiments for the end of the week.

In the afternoon, we prepared the 3D map and continued working on the experiments, knowing that only a few sessions remained!

Look Ahead Plan: Tomorrow will be the last EVA of photogrammetry of the mission, in the morning. In the afternoon, we’ll have our last session of brainstorming to bring up optimization solutions for the station. On Sol 25, no EVA is planned, and we’ll start to uninstall and pack experiments. On Sol 26 in the morning, we plan the last EVA of the mission to pick up the atmospheric instrument, and we’ll spend the rest of the day cleaning and packing, before breaking the simulation by the end of Sol 26.

Anomalies in work: None

Weather: Sunny, Temperature 35 F / 70 F

Crew Physical Status: Nominal

EVA: None

Reports to be filed: Sol Summary, EVA Report #14, EVA Request #15, Operations Report, GreenHab Report, Journalist Report, Crew Photos.
