Crew 311 Mission Science Report
MDRS, Friday 13 March 2025
Name of person filing report: Somaya Bennani – bennani.somaya311
Crew 311 has been in the MDRS for four weeks now, conducting experiments while simulating life on Mars. We have done everything we could to make this simulation as accurate and relevant as possible. The current report aims to give the reader an understanding of what has been achieved and what is yet to come.
This report is organized as follows: overview of all the experiments conducted during our mission, as found in the Mission Plan sent on Sol 1, reminded here for clarity, and updated with the experiments’ current status.
Name: LOAC / MegaAres / Field mill / Cosmic watch / Weather station
Type: Atmospheric physics
Crew: Robin (Crew Engineer) & Quentin (Crew Astronomer)
Description:
LOAC / MegaAres: These experiments, conducted since 2019, originates from the French National Center of Scientific Research (CNRS). It involves EVA operations and includes two key instruments: LOAC, an optical aerosol counter that measures and classifies airborne particles by size, and Mega-Ares, a sensor that precisely measures the electric field and air conductivity.
Field mill / Cosmic watch / Weather station: The experiment involves several measurement instruments to analyze environmental and space weather conditions. The field mill is used to measure the local electric field, providing insights into atmospheric electrical activity. The cosmic watch consists of two particle detectors that quantify the number of cosmic particles reaching the Earth’s surface. The collected data is analyzed in correlation with solar eruptions and coronal mass ejections (CMEs) to study their impact on Earth’s environment. Additionally, a weather station records precise atmospheric parameters at the observation site, contributing to a comprehensive understanding of local weather conditions.
Status:
All instruments have been deployed 400m away from the station on sol 3. The batteries have been charged and changed every two to three days and the data collected after each swap.
A significant amount of data was collected, but the Mega-Ares interface proved to be overly complex and did not match the outdated manual provided. The LOAC was returned to the base on SOL 18. A bug in the Mega-Ares interface prevented data collection. However, the other four experiments proceeded without any issues.

Name: AMAIA
Type: Technology
Crew: Isolde (Crew Journalist)
Description: The AMAIA system is integrated with station sensors, including environmental sensors and monitoring devices, enabling seamless data exchange. This integration allows AMAIA to estimate stress levels and provide data-driven responses to astronaut queries. Its capabilities support astronauts in their daily tasks by assisting with environmental measurements, voice recognition, and emergency exercises, enhancing both efficiency and safety in the station.
Status:
The computer LLM part of this experiment is working perfectly, we are currently using the AI assistant to translate report to English and also to have some recipes for our lyophilised food.
We tested the PIE code of ISAE Supaero, and while it functioned, it was not perfect. Various bugs appeared throughout the test, but due to communication delays, they couldn’t be resolved. The Amaia watches were not used by the crew because of these persistent issues.
