Journalist Report – April 10th

Crew 314 – Journalist report – 10 apr 2025
Author: Batoul Tani

This morning, Béatrice (commandant), Antoine (engineer), and Arnaud (executive officer) headed out on an EVA. After a quick check of Antoine’s equipment, the crew took Galileo Road toward Candor Chasma, a stunning canyon with striking Martian-like scenery. Dressed in their space suits, they may have felt (just for a few moments) like true explorers on Mars. The EVA went smoothly and offered breathtaking views throughout.
Back at the MDRS, the afternoon was more relaxed, focused on scientific work. Arnaud and Béatrice continued data collection for their joint experiment, which tracks heart rate, heart rate variability, sleep quality and duration, as well as responses to a supplementation protocol (either a placebo or a combination of Lactobacillus helveticus and glycine). Each participant also carries out a daily five-minute cardiac coherence session, a breathing technique known to support stress management.
Meanwhile, our journalist, Batoul continued her research by placing bacterial cultures outside to observe how extreme temperature variations affect their growth, an experiment that may offer insights into the effects of climate change. Bérengère, the greenhab officer, spent the whole day sterilizing spores for her experiment.
To wrap up the day, some crew members took time to unwind or get active. Arnaud finished his afternoon with a high-intensity bike session, a powerful way to cap off a day of exploration, research, and physical challenge.

Sol Summary – April 9th

Crew 314 Sol Summary Report 09-04-2025

Sol: 09-04-2025

Summary Title: Getting into a rhythm

Author’s name: Arnaud de Wergifosse (crew executive officer)

Mission Status: ongoing

Sol Activity Summary:

The day began with breakfast prepared by Odile, our Health & Safety Officer. A few crew members then headed out on an EVA focused on fossil hunting. Although no fossils were found, the outing allowed for team photos and a check of previously deployed equipment, all of which remained in place and fully functional.

Back at the habitat, Arnaud began data collection for the ongoing experiment with Béatrice, who took over later in the day after returning from the EVA. Antoine confirmed that the dust collectors in the field were still working properly.

On the science part:

Bérengère, our GreenHab Officer, checked that all equipment for applying environmental stress to arbuscular mycorrhizal fungi (AMF) was functioning properly. She also prepared the culture pots for a multi-day experiment launching later that evening and completed the GreenHab report.

Batoul continued her microbiological experiments by inoculating Bacillus thuringiensis (with and without soil) on Petri dishes, and Escherichia coli in a 96-well plate. Both were exposed to UV-C light as part of her research.

Meanwhile, Arnaud communicated with an academic collaborator to refine the experimental protocol and obtain necessary labeling materials. He also contributed to outreach efforts by sending photos and videos to one of the project sponsors.

On the technical and logistical side, Arnaud assisted Antoine with repairing a toilet leak and fixing a bicycle handlebar.

In the afternoon, several crew members took part in a Crew Resource Management (CRM) simulation led by Odile. Béatrice acted in the scenario, and Louis also participated.

Physical activity was a big part of the day: Louis completed a demanding 1-hour-and-20-minute cycling session, while Béatrice, Odile, and others joined in a group workout.

Despite some end-of-day fatigue, everyone contributed to writing the daily reports. A final highlight: Bérengère finished crafting scoubidous for each member of the crew.

Look Ahead Plan: One EVA is scheduled in the morning to carry out Antoine’s experiment. Throughout the day, we will continue working on our individual experiments, including full participation in Louis’ experiment, which focuses on user experience measurement of a portable communication device in an ICE (Isolated, Confined, and Extreme) environment. Béatrice and Arnaud will also continue their research while collecting data using their wearable devices.

Anomalies in work : No problem was discussed today. All experiments went well.

Weather: Sunny without clouds during the morning and the afternoon (Temperature between 39° and 83°F during the night and the day respectively)

Crew Physical Status: All crew members were feeling fine today, no health issue.

EVA : The crew departed from the station at 9:10 AM with two rovers: Opportunity (Driver: Louis, Passenger: Antoine) and Perseverance (Driver: Odile, Passenger: Béatrice), as Spirit had not fully charged overnight.

Their mission was to inspect equipment located at the intersection of Galileo Road and Cow Dung Road. En route, they made a brief stop to observe a group of deer crossing nearby.

The crew continued along Cow Dung Road to reach the Special Region, where they assessed the area as a potential site for future equipment installation. During their exploration, they stayed within 500 meters of the rovers.

After completing the inspection, they retrieved the rover at 10:10 AM on Cow Dung Road and proceeded to the intersection with Brahe Highway 1572, a location they had not been able to visit during EVA #4 where they used the drone to conduct a reconnaissance of the area.

Today, everyone was busy on Mars!
During sol 2, we carried out two EVAs with different objectives:
Morning: We collected soil samples for our journalist’s Batoul experiment.

Afternoon: The goal was to find a suitable location to place our engineer’s, Antoine, equipment.

We also had our first medical emergency simulation, followed by a valuable learning debrief of our Health and Safety Officer and the impression of the crew.
In the lab, Bérengère put her fungi to the test by exposing them to microgravity and UV light, while Batoul received her bacteria and was able to perform her first inoculations.
Finally, 5 members of the crew did the same strength training. They had the opportunity to have a great time exercising.
