Today was a bit special: Simon as health and safety officer declared it a rest day. We woke up 2 hours and a half later than usual, didn’t do our morning sport session, and had a brunch at 10 a.m. The EVA that was planned for the afternoon was also supposed to be special, as 5 people would take part to it, led by Simon and Xavier, to prepare us for emergency situations.

We all went downstairs for the EVA briefing at 1:30, where Simon and Xavier showed us how to react in case of emergency outside the station. In case of a medical emergency, the first thing to do is to notify the hab, and to put the victim in a safe posture: sitting down or in recovery position. It is not very difficult in everyday life as long as you know what to do, but with a spacesuit on yourself and on the victim, it clearly becomes a lot more complicated. Then, we must transfer the injured marsonaut. It is possible to give him oxygen, coming from another spacesuit, to increase the duration of the EVA, but he cannot stay outside forever. Here comes the second problem: transport the victim by foot to a vehicle, load him, and take him back to the station.

The reason why we only leave the hab being three, is because one has to stay with a potential victim, while the third one may have to leave to look for help or at least move to establish a radio contact. We also need to be minimum two inside the hab, in order to watch each other, such as EVA members that have to go at least by pairs. Mars is dangerous, and this is why we always have to be able to rescue each other.

Going back to our story, Xavier and Simon briefed the whole crew about all this, then, they left with Mouâdh, Louis and Arthur to repeat it on the outside, letting Victoria and I in the hab. Victoria was habcom, writing the report as the scenes were played outside, me working on the mission video.

Tomorrow will also be very special: a whole journalist crew from the BBC will visit us, to film the final part of a documentary on private exploration of Mars. Brian Cox, the reporter, will spend a whole day with us, following the simulation rules, while his team will try not to interfere with it. We are pretty lucky to have this opportunity, and the experience seems like it’s going to be very enjoyable!
