Journalist Report – February 24th

Sol 3 – Botanic emergency

Author : Nicolas WATTELLE

Definitely, a day without any complication on Mars, that may not exist…

Nevertheless, the day began quite well, I would even say that it was a very efficient work morning. One of the biggest challenges was setting up the antenna which we could not set the day before… The four martionauts chosen to do so were Valentine (she was wearing the Hololens during the whole outing today), Marine, Cerise and Léa. And, even if the task was not easy on paper, they appeared to manage very well: only one hour of the EVA was dedicated to achieve the tricky task.

This antenna is made of two big triangles (6 meters high), one in front of the other, directed towards France. It is called a Delta Loop, and ours was generously built by the radio club of Toulouse (REF 31), we were thus proud to see it set up in front of the Hab. We tested it, and the performances were encouraging, so that is good news for the future of our mission! A huge shout out to the four girls who made a perfect shot in EVA!

And then, the first unforeseen happened. Léa lost contact with her buddy beginning the last part of the EVA: her radio earphone and microphone had been unplugged while she was moving. So, writing on a paper to the three others, they decided to come back in the airlock, and the EVA was shortened. But this was nothing compared to what happened in the early afternoon…

We received a call from mission control. They discovered during the day that our GreenHab was compromised: white flies had contaminated the whole room so the future of all crops was at risk. The given instructions were clear: each Crew Member had to stop their activity and go to the GreenHab for a “big and fast gardening session”. We had to remove all the plants that were contaminated and assess the state of what can be salvaged and what was not.

First, we were worried for our disturbed schedule, but it turned out to be a great moment where we all had to work at the same place, at the same time. On top of this, the GreenHab atmosphere is always warm and really bright. Let’s say it, it was a pleasure doing it. But the result was quite sad: only few crops could had been saved, the GreenHab will not be usable for the next days. Currently, we do not know if we will be able to see fresh plants growing before the mission ends. The only kind we kept in our responsibility is the gravistropism experiment, which we are doing with school students back in France, which we moved to the ScienceDome.

At the end of the day, Elena the GreenHab officer had to write her last GreenHab report, and she will say goodbye to this special part of the station, that she had taken care of for the past four days…

Finally, we came back to our activities left uncompleted. And by the time I am writing these words, almost all the crew is helping to find ideas on how to cook the (big) harvest of the day: our lasts fresh vegetables of the mission.

EVA Report – February 24th

Crew 263 EVA Report 24-02-2022

EVA # 3

Author: Léa Rouverand

Purpose of EVA: battery change for atmospheric experiment, installation of antenna and geology field campaign with LIBS

Start time: 9:00

End time: 10:40

Narrative: Rover batteries were checked just in case. The atmospheric experiment batteries were changed per the usual routine. The installation of the antenna for the HF wave propagation experiment was performed without any issues. One of the crew members lost their earplug at the beginning of the LIBS analysis so the EVA team leader decided to return to base by communicating through a notebook.

Destination: Atmospheric experience site (at intersection between Cow Dung Road and Entrance Road), around the Hab (antenna installation).

Coordinates (use UTM NAD27 CONUS): 518288 E, 4250586 N

Participants: Cerise Cuny, Léa Rouverand, Valentine Bourgeois, Marine Prunier

Road(s) and routes per MDRS Map: Entrance Road.

Mode of travel: Foot

Sol Summary – February 24th

Crew 263 Sol Summary Report 24-02-2022

Sol: 3

Summary Title: Critical Alert in GreenHab

Author’s name: Cerise Cuny

Mission Status: Nominal

Sol Activity Summary: The morning EVA went pretty well, until one of the participants lost her mic, so we headed back to the Hab. The setup of the antenna was a great success and we were soon able to listen our first signals.

Just after lunch we were contacted by Shannon for an emergency in the GreenHab: we had to act right away to get rid of a fly contamination, all hands on deck. Sadly we had to get rid of all the plants, harvesting everything we could. There probably won’t be enough time to grow any new plants before the end of our sim. On the bright side, this evening, diner is going to be made of fresh vegetables.

This emergency prevented Elena and Mathéo from doing their afternoon EVA that should be postponed to Sol 5.

Look Ahead Plan: In the next days we are going to try to catch up with the missed experiments of this afternoon.

Anomalies in work: GreenHab emergency.

Weather: Mostly sunny.

Crew Physical Status: Good.

EVA: Two EVA’s. The morning EVA went well. The afternoon EVA was cancelled.

Reports to be filed: Sol Summary, two EVA Request, EVA Report, Operations Report, Journalist Report, HSO Report.

Support Requested: We found a tool holder in the RAM which would fit perfectly our LIBS analyser for EVAs and would also allow us to carry it in a safer manner. Could we use it during our EVAs? We would put it in the RAM immediately after use.
