Crew 222 EVA Report 28FEB2020

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.

Summary Title: Last martian day

Author’s name: Benjamin Auzou

Mission Status: Sim ended, ready to receive crew 223

Sol Activity Summary: In the morning, the crew woke up with the last matinal workout session. Then four of us went on the last EVA, exploring the area of Copernicus. The day was very similar to our other sols, but it was the last !

In the afternoon, we cleaning the Hab in order to prepare the crew transition. At 6pm, we opened the airlock that we closed at the same hour two weeks ago. We all took a deep breath, we are back on Earth after two wonderful weeks on Mars that taught us a lot.

Look Ahead Plan:

Tomorrow, we will wake up very early to enjoy the sunrise from the ridge. Then we will prepare the arrival of crew 223, prepare them a nice martian lunch, get water and food for their rotation. This day will be intense.

Anomalies in work: none

Weather: sunny

Crew Physical Status: all members safe and sound

EVA: Exploration of Hab Ridge

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.

Destination: Experiments site and Candor Chasma
Coordinates (use UTM NAD27 CONUS): 12S 0518494-4250679 and 12S
0519900-4251500
Participants: Benjamin Auzou (CO, EVA leader), Bleuenn Roiron (GHO),
Marie Bochard (Journalist), Nicolas Bourdeaud (HSO)

Title: Candor Chasma’s Charisma

For this morning’s EVA, we headed out towards Candor Chasma and the surrounding area by ATV. As scary as it is driving these beasts, the drive was fun and we all arrived safely at the end of the road. We even saw some antelopes that crossed the path in front of us! There were about 7 of them fleeing from the noisy quads. It’s strange seeing another form of life here, in this region considered to be so hostile to life! We walked down to the canyon, with the high snowy mountains in the background.

It was a beautiful walk through the canyon. We could see layers of history on either side of us, layers of colored stone forged by the ages. Red, white, green, all the colors were visible one after the other. We walked until the time forced us to stop, soaking in the beautiful canyon walls and the traces of antelopes on the path.

The walk back was rather exhausting as we had to climb back the way we came down, so we were glad to be back in the Hab. Riding the ATVs was definitely a fun part of the stay here.

This afternoon, Nina finished setting up the AeroSpring tower. The seeds planted last week in the moss grew enough to be transferred in the culture tower. What an exciting day. We filled the water tank below the tower with water, so that the pump can spray water inside the tower and water the plants. Lots of water involved. We turned the power on and hurray! It works. She will now come twice a day to turn on the pump that waters the plants, in hope that they will grow big enough to be harvested by the next crew!

Before dinner, we decided to play cards for our last evening together in the sim. We discovered new games and new rules, and had a lot of fun. Tonight, for dinner, the menu is red bean burger with chili and homemade bread! Spicy and delicious.
