EVA # 2
Author: Aurélien Mure (Commander)
Purpose of EVA: Change batteries of LOAC and MegaAres, and then first
exploration for Marion, Florian and Valentin.
Start time: 9:05 AM
End time: 11:05 AM
Narrative: First, we went out to check all the rovers and the water in
teams of two. We took then the two rovers to go on our experiments site
to change
batteries. We have had a serious problem with SpaceSuit 10 as it stoped
definitively. We reacted to this ermergency issue. We tried to restart
it and quickly we realised that we have to come back to the hab to save
me (SpaceSuit 10 user).
The EVA team worked well to make me survive! I came back to the Hab at
09:35 and I came out at 09:43 with a brand new Spacesuit. We respected
the 5min pressurisation protocol. We went back to the MegaAres location
to change the battery.
Today we needed to extract data from the instrument. We took out 2,4GB
of electric field measurement, great news for our partners from CNRS
(french national center for scientific research).
The data processing were long and after our issue with backpack 10 we
had not much time left but we went to Kissing Camel to explore during
half an hour.
We came back to the Hab at 11:00am.

EVA # 2
Author: Aurélien Mure (Commander) and Blandine Gorce (XO)
Purpose of EVA: Change batteries of LOAC and MegaAres, and then first exploration for the crew 223
Start time: 9:14 AM
End time: 10:57 AM
Narrative: First, we went out to check all the rovers and the water in teams of two. We took then the two rovers to go on our experiments site to change
batteries. Everything went fine so we moved a few meters to go to our site of exploration: the Marble’s Ritual. We arrived there at 09:43 to start our exploration, Curiosity was at 96% of charge, and Deimos was at 100%.
All of us were very excited for that. We walked for approximately one hour between Marble’s Ritual and Phobo’s Peak. Landscapes were really beautiful and we were amazed to see so many different types and rocks. We walked around to appreciate the landscape. Then we came back to the hab around 10:45. We entered the airlock again at 10:52 AM for our 5 minutes pressurization.

EVA # 13

Author: Marie BOCHARD (Journalist)

Purpose of EVA: Change batteries of LOAC and MegaARES, and then exploration of the Copernicus area

Start time: 9:15 AM

End time: 12:20 PM

Narrative: First, we checked all the rovers and the water level. We then took the ATVs to the experiments site and changed the batteries for the LOAC and the MegaARES in teams of two. Once that was all done, two of us we went back to the Hab with the batteries and left them in front of the Ram, because carrying them by ATV would have been dangerous. Once they were back, we headed up North to the Moons and Copernicus. We rode the ATVs on Brahe Hwy, but stopped soon after because the terrain was too rough for me to feel comfortable using an ATV. We stayed in Copernicus about 2 hours, exploring the area and enjoying our last EVA. Suit n°7 stopped working in the middle of the EVA, but this problem was solved by our Engineer once we were back (battery unplugged). At about 11:50 AM, we were back at the ATVs and headed back to the Hab. The Honda ATV had trouble restarting but worked in the end. We entered the station at 12:20 PM.

Destination: Copernicus Hwy

EVA #12
Author: Benjamin Auzou (CO)
Purpose of EVA: Replacement of the batteries of MegaAres and LOAC. Then
exploration from Galileo road to Candor Chasma.
Start time: 9:08am
End time: 12:30am

Narrative: We quickly replaced the batteries of MegaAres and LOAC. We
then headed towards Galileo road with 3 ATVs and Deimos. On the road, we
met a group of antelopes that crossed the road in front of us, we
managed to drive slowly and tried to disturb them as less as possible.
We stopped at the end of the road and then walked toward the canyon. We
walked along it and stopped at 11am to turn back. The road back to the
Hab was nominal. Near the Hab we took five minutes to take portraits for
the communication of our mission.

Purpose of EVA: Replacement of the battery of MegaAres, Setting up the
LOAC and exploration of the reservoir.
Start time: 10:00am
End time: 12:12pm

Narrative: Everything went just fine. We rapidly changed the battery and

EVA # 7
Author: Benjamin Auzou (CO)

Purpose of EVA: Replacement of the battery of MegaAres. The goal is to have a full battery before the rain episode so that the experiment can stay alive, even if no EVA is possible due to the rain or the mud on Sunday.

Start time: 9:31pm
End time: 10:04pm

Narrative: Everything went just fine. We rapidly changed the battery and assure the waterproofness of the experiment.

EVA # 5
Author: Nina SEDBON (Scientist)
Purpose of EVA: Change the Batteries if the LOAC and the MegaAres. Explore the white Moon site.
Start time: 9:15
End time: 11:16

Narrative: Everything went just fine. It was very cold on the rovers to go the exploration site. We changed the batteries rapidly because we gain efficiency day after day.
After that we drove to the white moon. There, we reached a little panorama on a hill. It was amazing to look quietly at the landscape. It was as if we were actually on another planet. The colorful traces of mud were very artistic. It appeased us to feel the outside, although we were wearing our flight suits.
The rovers lost their batteries quite rapidly, so we had to be careful about that.
