Journalist Report – April 27th

Crew #: 335
Position: Crew Journalist
Report prepared by: Matteo Calore
Date: 27APR2026
Sol: Day 8

Report Title: Windy Focus

Today was a long day. We woke up, as usual, between six and seven, and had a quick breakfast before moving into our regular morning meeting, pleased to see that we are managing our resources well. The challenge of living in a space with limited resources is always interesting, but for some of us it is not new, so it comes quite naturally.

As the days go by, each of us is increasingly focused on completing our own projects, so interactions have become fewer. From the initial desire to get to know one another, we now feel the pressure of time and the need to bring to completion what we started. Overall, we are all making good progress, and aside from a few interruptions, we remain well organized.

The desert and the isolation help us stay more focused, even though some of us are finding it more difficult, especially due to trouble sleeping at night. Some are particularly affected by the dry desert air. Still, we are gradually adapting to this way of life, and being surrounded by the beauty of these hills—where red and white dominate, touched by the intense sunlight—helps us stay concentrated.

Sol Summary – April 27th

Sol Summary Report

Crew #: 335
Position: Crew Artist
Report prepared by: Lot Brugge
Date: 27APR2026
Sol: Day 8
Summary Title: Windy
Mission Status: Towards the end

Sol Activity Summary
We woke up around 07:00 and had a quick breakfast. One crew member continued to rest due to an accident the previous day and is not yet in good condition, so additional recovery time is needed to continue the final days of work.

The rest of the crew began the day with the usual morning meeting to review activities and overall status. Water consumption remains stable. Some crew members completed reports that had been delayed, as the previous day’s schedule was interrupted by a visiting crew of journalists from England, preventing us from fully carrying out planned simulation activities.

After the meeting, each crew member focused on their individual projects. Charlotte continued working on her clay project, while the film crew documented activities and organized interviews with each crew member.

In the afternoon, the film crew conducted an interview with the Commander and later performed a short EVA around the station to document MDRS at sunset. The rest of the crew remained inside: Charlotte continued her work, and the Commander rested in the living area.

Anomalies in Work
The planned EVA destination was changed and postponed to the following day due to strong wind conditions and the health status of one crew member.

Weather
The morning was sunny and mild. In the afternoon, wind increased significantly, and light rain occurred around sunset.

Crew Physical Status
One crew member continues to experience a persistent cough. Another is recovering from an accident and requires rest.

EVA
The filmmakers conducted a short EVA to capture footage of MDRS at sunset.

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
