Report title: Sol Summary Report

Crew #: 330

Position: Crew Commander

Report prepared by: Gaspard THIEULIN

Date: 24/02/2026

Sol: 9

Summary Title: Another great day on Mars

Mission Status: Going great

Sol Activity Summary:
Today feels like our mission is finally going smoothly, and some kind of routine is setting up. Maybe opposite from what we seek on Earth, this routine actually feels great and relaxing during an intense mission so far.
We got the time to conduct some maintenance and repairing in the station, and we keep on conducting our experiments without major difficulties.
Our first exploration EVA in the morning was a success, and the team was in awe during their walk on the beautiful surface.
Our HSO organized a crew meeting in the afternoon, so that we could all take the time to express our feelings of the first third of our mission. It was really well received, and everyone felt good and closer to the entire crew at the end.

Look Ahead Plan:
We are still working on the Photogrammetry experiment and should conduct the following EVA Thursday and Friday. Our planning feels nicely set up, with a nice balance between advancing our scientific experiments, maintaining the station and taking the time to rest and relax.
We are looking towards our big resupply at the end of the week, as we are beginning to lack the best ingredients of our food supplies.

Anomalies in work:
– Issues with EVA radios headsets (not yet troubleshot, but healthy radios sets have been identified)
– Issue with the Musk Observatory Dome.

Weather: Sunny

Crew Physical Status: Physically fit and well

EVA:
– EVA 08 Conducted with success
– EVA 09 to be planned, for exploration

Reports to be filed:
– EVA 08 Report
– Journalist Report
– Greenhab report
– Operations report
– Astronomy report

Support Requested: If possible, we would like to have a resupply of the following in advance :
– Dehydrated milk
– Handsoap
– Burger Mix and/or Ground Beef
Please find attached the current inventory of our food supply.

Journalist Report – February 23rd

Report title: Journalist Report

Crew #: 330

Position: Journalist

Report prepared by: Adrien Saugnac

Date: (23-02-2026)

Sol: 8

Journalist Report Title (if applicable) : First step far from the station

Soon after waking up, we started the day with an upper body strengthening session organized by Adèle. Then, it was time for Célia, Lou and I to leave for a photogrammetry EVA. The objective was to head to Compass Rock to set up way points and take pictures with the ANAFI AI drone from Parrot. These pictures will allow us to create a 3D map of the site. We will then organize orienteering EVAs, where two teams will have to look for checkpoints, after going through a different training. One team will have access to the 3D map, while the other team will only use a 2D map. We will compare their efficiency. The first team will be composed of Adèle and Gaspard, studying the 2D map, while Félix and Julien will have access to the 3D map. It was the first time that we could go as far and we were amazed by the views offered to us. We really felt like we were exploring a new world !

During this time, Felix was acting as CapCom of the EVA and continued working on his botanist project with Gaspard. He set up the webcam and prepared the python script for the Raspberry Pi. Julien is working on a paper for a conference in Munich that will take place in April : the SSEA. It is about the scientific mediation that we have done in primary, middle and high schools during our year of preparation and our mission.

Today, Adèle has also started to do interview with Gaspard, Félix, Julien and Lou. As an HSO (Health and Safety Officer), she makes sure that everyone feels good. These moments allow us to have a one-on-one discussion, which is rare in such a small space. Our rooms are 4 m² and the HAB (our main habitat) is 8m in diameter and is divided into 2 floors and a mezzanine. So we spend most of our time in a small space, and being able to meet in small numbers is critical to be able to confide in each other.

This afternoon, Gaspard tried to make distilled water for the GreenHab but the
equipment was not suitable. Célia went to the observatory but the dome had a
problem and no longer opened.

Felix, Celia and Lou had a session of the NeuroErgonomics experiment and Adèle and I had a session for Orbital Architecture. These are two human factors experiments where the tasks we have to perform are similar. In both cases, the objective is to study how confinement impacts our cognitive skills and it is therefore interesting to carry them out during analog missions.

Tomorrow, Adèle, Félix and Julien will go even farther on the Red Planet.

Summary Title: Troubleshooting day

Mission Status: Going great, solving problems on all fronts

Sol Activity Summary:
Today seemed to be dedicated to troubleshooting, more or less on purpose. The EVA this morning was the first session of orienteering for the Photogrammetry experiment. We got interesting data with the 2D map, with some ideas for the next session. The drone however was locked in a small geographic area, and we couldn’t do the shots we wanted. Back in the station we had a look at the options of the Drone and found the issue with a Geo-locking function.
We also had better result with the 3D printing today, after switching the PLA filament and heating the printing bed a bit, after lots of trials and frustrating botched prints.
In the afternoon, we could troubleshoot the faulty radio sets. We identified at least one of them to be faulty, with a connector pin seemingly disconnected (more info in the Operations Report). The others seem to be alright but we will keep a close eye / ear on it.
Later in the day, Lou, Célia and I worked on the Observatory, following the green light from Peter. We found several issues with the setup, and we will continue working on it with a close collaboration with Peter.
Our experiments are still running and gathering data. The crew feels great and motivated towards our next rest day and the mid-point of our mission. We keep working on our video which will be published next week.

Look Ahead Plan:
The 3D map orienteering Photogrammetry session will be conducted tomorrow. We are finishing the week with great scientific results, and a great morale among the crew. We are still feeling tired from the isolation and confinement in the station, and are very much looking forward for our rest day on sol 13.

Anomalies in work:
– Issues with EVA radios headsets (troubleshot, one is faulty)
– Issue with the Musk Observatory Dome (solving in progress with Peter).

Weather: Sunny, a bit windy in the afternoon

Crew Physical Status: Physically fit and well

EVA:
– EVA 10 Conducted with success
– EVA 11 to be planned, for Photogrammetry

Reports to be filed:

Journalist Report Title (if applicable) : Mars as far as the eye can see

We woke up with a dance session prepared by Adèle and Lou. We started with 20 minutes of Just Dance and then we followed a Bachata class from Lou.

Today, we kept on exploring ! This time, Lou, Célia and Gaspard went in the direction of Kissing Camel Ridge. They were able to bring the PARROT drone to take some beautiful videos from the base, the rovers and their exploration by foot. Once again, they discovered new landscapes before their amazed eyes. Coming back from the EVA, Gaspard told us : “You can witness Mars as far as the eye can see, there is no sign of life there”.

Meanwhile, Julien went to the Science Dome to perform an Orbital Architecture session and Félix planted the radishes and worked on his RaspBerry Pi. Adèle prepared her next HSO briefs: we will keep on practicing with the tools that can help and guide us for our introspection and relationship with others. In the context of isolation, our social interactions are limited to those we have inside the crew. It is very important to keep working and informing ourselves on Non Violent Communication. Whether it is in our everyday life, but even more while we are on a mission like this one, having tools that allow us to learn more about ourselves strengthens our connexion with others. This guarantees a healthy climate in the station, where the needs and limits of everyone are fully respected.

In the beginning of the afternoon, we did a team brief for the preparation of the mid-mission video. We are going to film a short movie about what we are living and the experiments we are conducting.

Adèle then went to the Science Dome to install the NeuroErgo experiment, so that Julien and Gaspard could then perform their sessions. With Célia, we went to the observatory to identify why the roof refuses to open, preventing any solar observation for the last 3 sols. After testing the voltage of the batteries, we detected an issue on a mechanical stop for the opening mechanism.

In the end of the afternoon, Lou and I finalized the preparation of the Photogrammetry experiment. Tomorrow, a first team will leave with the 2D version of the map to do the orienteering race we prepared on Sol 9.
