Journalist’s report.
Author: Batoul Tani

Today was marked by extreme weather conditions. However, in the morning, an EVA was carried out, specifically the one dedicated to retrieving Antoine’s equipment. Later on, rain and lightning around the station and in the Utah desert made any outdoor activity in the afternoon impossible, making this day particularly memorable in terms of weather. As a result, no EVA will be conducted tomorrow either.
Taking advantage of this forced break, the crew dedicated more time to video documentation, filming longer sequences on the various ongoing experiments.
On the science side, the laboratory work for the microbiology experiment led by Batoul, the crew journalist, was completed today.
Tonight, the final emergency medical simulation was conducted under the supervision of Health and Safety Officer Odile. This time, the scenario involved an imagined smoke-filled Greenhab, adding an extra level of difficulty to the drill.
The physical activity remains intense, especially with the upcoming completion of Béa and Arnaud’s study on the impact of physical exercise on attention. The final questionnaires will be distributed to the crew tomorrow to conclude the experiment, as the last pedal strokes are approaching!
Bérengère, the Greenhab Officer, is now in the final stretch of her experiment, continuing her efforts to meet her objectives before the end of the mission.

Crew 314 Operations Report 17-04-2025

SOL: 11

Name of person filing report: Antoine Dubois (Engineer)

Non-nominal systems :

Tunnel inspection and some damage due to wind.

Suit #3 has been repaired.

Notes on non-nominal systems :

A tunnel inspection was conducted in the early afternoon, and all coverings were found to be in good condition. A second check was carried out at 6:30 PM, during which one tarp near the RAM was found to be damaged. It was reattached, but should be monitored closely in the coming days due to ongoing wind conditions. Approximately 15 zip ties were used to secure other sections of the tunnel, and no additional damage was observed.

Suit #3 : The missing part was hidden at the top of the shelf. The part has been attached to the suit. The suit is operational.

Summary of Hab operations: Over the past 24 hours, we participated in our final medical emergency simulation. The scenario began at midnight, when we were woken by an alarm in the Hab and directed to the GreenHab, where the simulation took place. After completing the exercise, we returned to the Hab for a debriefing session and were back in bed by 1:00 AM.

Later in the day, we spent time cooking, socializing, advancing our experiments, and working on individual reports. We also engaged in physical exercise to maintain our fitness. To conclude the day, we held our regular team meeting to review our progress and plan the tasks ahead.

Summary of RAM operations:

Around 15 Zip ties were used to repair the tarps that had been damaged by the wind.

Summary of any observatory issues: No observation today due to bad weather.

Summary of health and safety issues: Everyone was in good health today, with no issues reported. There were no safety concerns to note.

Questions, concerns and requests to Mission Support: None

Today, two Extra-Vehicular Activities (EVAs) were conducted.

The first EVA took place in Condor Chasma and was primarily aimed at collecting soil samples for Bérengère (GreenHab Officer) as part of her ongoing microbiological experiment. The mission went smoothly under favorable weather conditions.

The second EVA, conducted at Skyline Rim, proved to be more challenging due to strong winds which significantly hindered movement and visibility. Despite the adverse conditions, the crew managed to achieve the primary objective: exploring and assessing new terrain that could be suitable for future EVAs.

Meanwhile, in the Science Dome, Batoul (Journalist) analyzed the results of the Bacillus thuringiensis experiment. The initial outcomes appear promising and will undergo further analysis for interpretation. In addition, several other experiments reached completion today, with samples either archived or disposed of in accordance with the established protocols.

In the main habitat, the end of the mission is beginning to be felt. Louis (Astronomer) has started analyzing the data from his observations, and several crew members have begun working on their End of Mission Reports.

In the lab, Bérengère carried out a staining procedure on fungal samples using violet dye to assess germination. The dye improved visibility of the spores under the microscope, and preliminary observations indicate successful germination in some samples.

Despite the difficult weather conditions encountered during the second EVA, the day was productive both in the field and in the laboratory.
