EVA Report – February 23rd

Report title: EVA Report

Crew #: 330

Position: Journalist

Report prepared by: Adrien Saugnac

Date: (23-02-2026)

Sol: 8

EVA #: 07

Purpose of EVA: Exploration and 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: 9 : 55 AM

End time: 11 : 35 AM

Narrative: We took 18 minutes with Curiosity and Opportunity to go to Compass Rock because we had trouble finding the entry of Galileo Road 1104. Once we were on site, we started the drone and took pictures of the site, and we decided where the checkpoint of the orienteering race will be. The goal will be to evaluate the quality and usefulness of the 3D map.

At 11:10 AM, we headed back to the station and the EVA stopped at 11:35 AM without issues.

Destination per MDRS Map: Compass Rock

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

EVA Participants:

– EVA Leader : Adrien, Journalist
– Célia, Astronomer
– Lou, Engineer

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

Mode of travel: driving and walking

MDRS ROBOTIC OBSERVATORY

Robotic Telescope Requested (choose one MDRS-14 or MDRS-WF): MDRS-WF

Objects to be Imaged this Evening: messier 42

Images submitted with this report: None

Problems Encountered: N/A

MUSK OBSERVATORY

Solar Features Observed: N/A

Images submitted with this report: N/A

Problems Encountered: The dome shutter didn’t open. Nothing happened when I switched on the dome shutter and maintained the "Open" position. When I arrived, the black box was on OFF so I’m pretty sure I didn’t drain the battery. And when I put the switch on the "Close" position, the dome made its moving sound for one second and stopped, as if it was working in the closing way but stopping because it is already closed. It seems as if the Open position only doesn’t work.

Summary Title: Finding our rhythm

Mission Status: Going great

Sol Activity Summary:
We all got to sleep quite early last night and got up rested, but still feeling a bit sleepy. This morning’s physical activity got us working our core and upper body, which woke us up nicely. We again made progress today, and most of our experiments are running and gathering scientific data. This morning’s EVA allowed us to start conducting the Photogrammetry experiment, and it went perfectly. Félix is making great progress with the set up of his botanic experiment, the Supaeromoon rover is printing slowly but surely and Julien got the time to work on his research paper for the SSEA in Munich.
Only the observatory got in our way today, as the dome refused to open all day.
The planning was meant to be lighter to day, and we followed it quite nicely, even taking the time for a little nap in the beginning of the afternoon.

Look Ahead Plan:
We are beginning the hardest part of our mission, and are getting prepared to ride it smoothly with the least difficulties possible. The rest of this week’s EVA will be dedicated to maintaining the atmospheric experiments, exploring and conducting the rest of the Photogrammetry experiment.

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 07 Conducted with success
– EVA 08 to be planned, for maintenance of the atmospheric experiments and exploration

Reports to be filed:
– EVA 07 Report
– Journalist Report
– Greenhab report
– Operations report
– Astronomy report

Support Requested: None

Journalist Report – February 22nd

Crew #: 330

Position: Journalist

Journalist Report Title (if applicable) : Full throttle toward the second week !

Today’s program : two extravehicular activities. Julien, Adèle and I went outside the station this morning, while Lou was acting as CapCom. The goal was to change the batteries of the atmospheric instruments and to explore an area located farther from the station, called Compass Rock. In the first few minutes, we faced a communication issue as Adèle’s radio was not functioning properly. It took us time to identify a false contact between her headset and her radio and to find a solution, making us lose 30 minutes. My radio also broke halfway through the EVA for the exact same reason, but we were able to react faster. We didn’t have time to explore but we could successfully replace the batteries. When entering our spacesuit, we really feel like we are on Mars. We see through a window, our movements are restrained and we don’t hear any sound other than the words of our crewmates over the radio. When exiting the station, we immediately have a tunnel vision and must therefore be even more vigilant, because this is when mistakes can arise. Our radio is the only way to communicate and when it breaks down, on the Red planet, far from the station, we felt particularly lonely.

In the meantime, Célia could make her first observations using the solar telescope ! Until today, it was too windy to open the dome protecting it, but the weather conditions are finally ideal !

Félix worked with Gaspard on his botany project. The objectiive is to study the potential use of the resources coming from a confined space to improve the soil fertility. He uses a Rasperry Pi to monitor humidity, temperature and take pictures of the plants growing in the GreenHab.

This afternoon, Gaspard, Félix and Lou performed an EVA to move the atmospheric instruments west of Marble Ritual, where they will be more protected. Adèle acted as CapCom and we could test a new EVA protocol that we wrote after the morning EVA. The EVA team could exit and enter the station again without any problem.

Later in the afternoon, Félix, Célia and I went to the GreenHab to water the plants and Félix showed us hier his germinating broccoli microgreens. Adèle, Gaspard and Julien went to the Science Dome to complete sessions for the Orbital Architecture and NeuroErgonomics experiments. Lou kept 3D printing components of the SupaeroMoon rover.

We are waiting for the communication window, completing our daily questionnaires. Tomorrow, if the weather is favorable, we will use the Parrot drone to start building a 3D map of the Red planet.
