Sol Summary – February 20th

Crew 311 Sol Summary Report 20-02-2025
Sol: 4
Summary Title: The wind blows in the sails of Crew 311
Author’s name: Erin Pougheon, Crew Commander
Mission Status: Nominal
Sol Activity Summary: Sol 4 allowed Crew 311 to continue installing some experiments, and to start some sessions of the HUMANISE experiment. Crew Engineer started teaching 3D printing to other crew members. We tried to debug AMAIA, our AI assistant, and it works but not perfectly. We also launched for the first time all the measurements for the Orbital Architecture experiment (heart rate sensor, location tracking,…).
Crew Astronomer and GreenHab Officer thought about how to organize the EVA that will take place during Sol 6. The objective will be to take some drone pictures for the stratigraphy experiment.
During the afternoon, Crew continued their activities and finished installing the lights in the Lower Deck for the Lattal experiment.
Look Ahead Plan: Tomorrow will be dedicated to the installation of some experiments. Some crew members will create a sign to place near the atmospheric instruments during the next EVA and other features to monitor the battery. We’ll also start to count the water used and for which usage. GreenHab Officer will also train some other crew members on how to use the drone.

Weather: Cloudy, Temperature 35 F / 45 F

Sol Summary – February 19th

Crew 311 Sol Summary Report 19-02-2025
Sol: 3
Summary Title: A break to freshly restart the day!
Author’s name: Erin Pougheon, Crew Commander
Mission Status: Nominal
Sol Activity Summary: This morning, three crew members went on EVA to install 4 atmospheric instruments: LOAC, which analyze the atmosphere and aerosols, MegaAres and the Field Mill, which analyze the electric field and a weather station. The EVA went very well, and they even finished earlier than planned. While the EVA was going on, Crew Scientist started the HUMANISE experiment by teleoperating a rover.
After a delicious lunch prepared by Crew HSO and Crew Scientist, the whole crew took a well-deserved break. The afternoon was quite calm but productive: GreenHab Officer finished planting the micropouss and took photos for our outreach activities!
As every day, the end of the afternoon is fully dedicated to filling in questionnaires and preparing the communication window!
Look Ahead Plan: Tomorrow will be dedicated to continuing the installation of the experiments we started, such as testing that all the data from the Orbital Architecture experiment is well collected. We also want to start working on new experiments, such as for example the building of a rover from scratch with a 3D printer.
Anomalies in work: None
Weather: Cloudy, Temperature 30 F / 50 F

Journalist Report – March 11th

SOL 23: The rover has landed

04:17 PM: This morning was a bit different from the others. We struggled to create the map of Kissing Camel Ridge yesterday, despite the 800 photos that Somaya had taken. The schedule was rearranged at the last minute because Robin and Quentin were unable to study the 2D map last night. Everyone was also very tired, so this morning, the crew woke up a bit later than usual, and Robin and Quentin studied the map during the 45 minutes preceding their EVA. They then left with Célyan, who was in charge of observing their performance, and Somaya, who took more drone photos of the area. EVAs with four crew members are rare, and the HAB was quite calm in the morning. Meddi and Erin took advantage of this to plan the organization of our bags to lose as little time as possible on the last day of the mission when we will leave.

At the end of their exit, the EVA crew members returned to the base to take out the rover from SUPAEROMOON, which was ready for this moment. The ISAE-SUPAERO club could not provide us with a robotic arm for the rover, so we won’t be able to test it fully, but this mechanism leaves a perfectly adapted space for… Didier, our mascot!

After taking refuge in the station and taking a well-deserved break, Quentin went to the observatory. I then heard from my room a message coming from the mission support walkie-talkie. It informs us that one of our rovers, which we use to move during EVAs, is no longer operational for the rest of the mission. This rover was really useful as its battery allowed us to reach distant regions of the station, like the Sea of Shells area. Fortunately, this week, we will stay in spaces near the base, and the remaining three rovers will be more than enough. Suddenly, Quentin also called the HAB from a walkie-talkie and informed us that the tunnels are being damaged again. Meddi and Robin went to rescue our movement spaces to prevent their condition from deteriorating, which would cause another emergency EVA rather unwelcome at this busy time.
