Sol Summary – February 25th

Crew #: 330

Position: Crew Commander

Report prepared by: Gaspard THIEULIN

Date: 25/02/2026

Sol: 10

Summary Title: A productive day

Mission Status: Going great

Sol Activity Summary:
This morning we woke up with a dance session prepared by Adèle and Lou. We all had a good night of sleep and feel quite rested. At breakfast, we tasted some chocolate paste cooked by Lou from the cooking ingredients we have left in the station. She asked our onboard AI (AMAIA) for the recipe, and it turned quite well.
The planning of the day was again lighter than our first week, with a load that we can sustain for the rest of the mission, while our experiments are set up and running without too much work. In the morning we conducted another exploration EVA, dedicated to taking lots of pictures and videos, with the help of our drone.
This afternoon we kept on working on our experiments, and got the time to troubleshoot some of the station’s issues, with some success.
We got a crucial little resupply from mission support which should suffice until our full resupply at the end of the week, thank you !

Look Ahead Plan:
We will keep on gathering scientific data from our experiment, and fixing some of the issues we encountered in the station during the last few days. The next EVAs will be dedicated to the Photogrammetry experiment and keeping on maintaining our atmospheric experiments outside on the field.
Two more sols until the second rest day and the half of the mission !

Anomalies in work:
– Issues with EVA radios headsets (not yet troubleshot, but healthy radios sets have been identified)
– Issue with the Musk Observatory Dome: solving in progress with Peter
– Battery of backpack #4 replaced.

Weather: Clear

Crew Physical Status: Physically fit and well, rested

EVA:
– EVA #09 Conducted with success
– EVA #10 to be planned, for maintenance of the atmospheric experiments and Photogrammetry

Reports to be filed:
– EVA #09 Report
– Journalist Report
– GreenHab report
– Operations report
– Astronomy report

Mission Status: Going great, rest day tomorrow

Sol Activity Summary:
Concluding a successful week, today went great and we conducted all our experiments without any issue. As mentioned in the previous report, we will publish a video during our mission, to showcase everything we have been doing in the first half of the mission. Today we filmed a lot of scenes to illustrate our mission as best as possible, and we should have enough material to keep assembling the video. Tonight everyone feels relaxed, as we are planning an evening of fun activities before our second rest day.
Some of the crew is also working hard on writing abstracts and articles for upcoming scientific congresses, namely SSEA and IAC, as the submission deadlines are tomorrow.

Look Ahead Plan:
Rest day tomorrow, and then the start of the second half of our mission ! We will publish our mid-mission scientific summary on Sol 13.

Journalist Report – February 26th

Report title: Journalist Report

Crew #: 330

Position: Journalist

Report prepared by: Adrien Saugnac

Journalist Report Title (if applicable) : Finding the North without magnetic field

Last night, Félix organized an activity in the GreenHab. Everyone was able to plant flower seeds in their pots. If everything goes well, they will sprout out of the ground in 2 days and will have grown in 15 days.

This morning, Adèle organized a cardio session. After that, it was EVA orienteering for the team with the 2D map: Adèle and Gaspard. I went with them to organize the race, take photos and videos with the drone. Before leaving, they had a preparation time to preview the positions of the beacons on the 2D map. Then, we moved by rover to Compass Rock and we went to the starting point of the race by foot. We started the stopwatch and Gaspard and Adèle were able to begin the race. In 30 minutes, they found 5 beacons out of 8, which gave them 5 letters that form a word. They managed to guess it. The outing was very physical, it was very hot, and we returned exhausted. Tomorrow, the team with the 3D map will do the same race and we will compare their results.

Meanwhile, Julien, Célia, and Félix worked on writing abstracts and an article. An abstract is a summary that allows proposing a scientific publication on an experiment or aspect of our mission at the occasion of a conference. Célia and Félix started writing an abstract about the Lab’Ex experiment for the IAC. Julien almost finished writing an article on our scientific mediation activities he will present at the SSEA conference in Munich in April.

This afternoon, Félix worked on his botanist project. He prepared the pots that will host micro sprouts of watercress. His Raspberry is programmed to automatically take measurements of temperature, humidity, and light.

Gaspard, Lou, and Célia continued working on the repair of the opening mechanism of the observatory and started building a new limit mechanism. They were almost able to install it, and Célia will be able to make solar observations tomorrow!

Sol: 11

EVA #: 10

Purpose of EVA: Orienteering for photogrammetry experiment

The photogrammetry experiment aims to create 3D maps of the terrain around the MDRS. The quality and usefulness of the map will be assessed by other EVAs, using the map to orient themselves. This maps are created using Drone imagery, and this first EVA aims to map out a first point of interest outside of the station.

Start time: 10 : 30 AM

End time: 12 : 15 AM

Narrative: We went to Compass Rock with Curiosity and Opportunity. Once we were on site, we started an orienteering activity. Gaspard and Adèle searched the points we chose during EVA #7. The activity lasted 30 minutes and then we started using the drone for videos. We gathered interesting datas for the photogrammetry experiment. We couldn’t take a shot while driving the rovers due to a configuration issue but we fixed it after coming back to the station.

Destination per MDRS Map: Compass Rock

Destination Coordinates (use UTM WGS 84): 520000 E, 4252000 N

EVA Participants:

– EVA Leader : Adrien, Journalist
– Gaspard, Commander
– Adèle, HSO

Road(s) and routes per MDRS Map: Cow Dung Road towards North, Galileo Road 1104

Mode of travel: driving and walking
