Journalist Report Title: SOL-1

This morning, Adèle organized a yoga session for us upon waking up. After that, we were ready to begin our last full day of simulation. Tomorrow in the late afternoon, our mission will come to an end, and we will be able to go out without a suit.

Julien, Lou, and Gaspard worked on the SupaeroMoon rover because we had planned to retest it this afternoon. Yesterday, Julien, Lou, and I did an EVA to try to launch its functionalities, but we did not succeed in connecting it with the computer. This morning, we finally succeeded in making it work in the station and decided to take it in the afternoon on an EVA. It was Célia, Adèle, Félix, and Julien who participated in the last extravehicular outing of our mission. The first step of the EVA was to go get the atmospheric instruments that we had installed at SOL 4. After that, they were able to connect the rover and, for its functionalities, we succeeded in making it move, move its robotic arm, and weigh rocks. It is therefore a real success and we thank the SupaeroMoon team for entrusting us for two years with their entirely 3D-printable rover project.

Lou prepared a 3D printer which will be useful for next year’s MDRS crew.

Adèle and Gaspard continued to do the assessment of the mission. It is an important report to present what we have done during these 26 sols of simulation. It reviews our mission objectives and what we succeeded in accomplishing.

All day long, we continued to film our activities in the station. We did the interview with Lou, presented our management of water and resources. Félix made a vlog of the use of the greenhouse by presenting what he grows there and his botanist project. In the late afternoon, Célia presented how a solar observation takes place.

In the late afternoon, we were able to play chess with the set that the students of the high school of Prades in the specialization of 3D modeling and prototyping designed for us. We were also able to use a sound amplifier that they also modeled. We thank them for their investment in our mission!

Tomorrow will already ring the end of our mission, and we have a busy schedule of tidying and cleaning of the whole station where many emotions will mix.

Sol Summary – March 12th

Summary Title: Wrapping up

Mission Status: Going great, 1 sol left

Sol Activity Summary: We were again quite busy today, as the objective was to wrap up the bulk of most of our experiments. In the morning, we continued to work hard on the SupaeroMoon rover, to fix some of the issues encountered yesterday before our final EVA in the afternoon. We kept progressing on our end of mission reports and assessments, and we filmed as much as possible for the mission’s documentary.

In the afternoon, we conducted our last EVA. It was emotional for the EVA team, as they recalled all the good times spent discovering beautiful landscapes around the station and thought about wearing the suit one last (perhaps not so !) time. The team successfully disassembled the atmospheric experiments and could test the SupaeroMoon rover in the field again. It behaved better this time around, and we have tons of feedback for the team back in France.

We are spending our last evening in simulation in the MDRS and we are getting kind of emotional. It has been such a wonderful experience these past few weeks, and we look back with so much feelings.

Look Ahead Plan: Tomorrow will be our last sol in simulation, which we will end at 17:00. We will thoroughly clean the station in the morning, wrap up every last experiment and publish our end of mission reports in the afternoon. We look forward to coming back to Earth, not without some nostalgia about the time we spent on our simulated Mars.
