Purpose of EVA: Changing the atmospheric equipment battery and exploration of Compass Rock

Start time: 11:20

End time: 12:47

Narrative:

The goal was to change the atmospheric equipment battery near East of Marble Ritual and then continue to the North and then East to Compass rock to explore the area.

We had several issues during the EVA. First, we forgot to take the battery when we left the airlock, so we had to do another 5 min of decompression. Then, when we arrived at Cow Dung Road, we had a communication problem. The radio of the HSO stopped working, it was a false contact, it took us 30 min to solve the problem. Because of this time loss, we decided to just change the battery and to cancel the exploration to Compass Rock. The operation went well, there was just a lot of dust and mud so It was difficult to walk. When we handed back to the station and to the airlock, we figured that we forgot the Safety Kit and the Battery in the rovers so we had to go outside again and do another decompression. After the EVA, we decided to make a clear procedure for the EVA preparation and the equipment so that we won’t forget anything for the following EVAs. It was a little bit frustrating because we didn’t have time to do everything but it was a good experience so that we can improve during the mission !

EVA #: 06

Purpose of EVA: Displacing the atmospheric instruments

Start time: 14:15

End time: 15:30

Narrative:
The installation of the atmospheric instruments during EVA #04 was overall a success. However, we couldn’t monitor the experiments from the Hab as planned. We decided to conduct a short EVA to move the instruments to a new location, closer to the Had West of Marble Ritual to keep some visual contact.
The distance to cover was very short, and we initially planned to conduct everything by foot. However, the ground is still muddy here, so we decided to use the rovers to get to the Marble Ritual site to increase the overall safety of the EVA.
We used the manual cart to move the cumbersome instruments, which proved very useful, especially on muddy grounds, allowing us to keep our balance while walking. We also studied the terrain before choosing our path on each side of the road, to avoid the muddy parts as much as possible (by staying on high ground mainly).
Another goal of the EVA was to gather the first piece of data from both experiments, which was done successfully. We successfully moved both experiments, along with their new battery to a location visible from the Hab, North West from Marble Road. We were able to restart the LOAC experiment, but we missed a piece of equipment to restart the Field Mill. Being short on time, we decided to come back to the station, and the next EVA will bring the right equipment to start the experiment again (it only requires to press one button at this point of the setup).
Every system was nominal during the EVA, even radios and no incident happened.

EVA #: 07

Purpose of EVA: Exploration and Photogrammetry experiment

The photogrammetry experiment aims to create 3D maps of the terrain around the MDRS. The quality and usefulness of the map will be assessed by other EVAs, using the map to orient themselves. This maps are created using Drone imagery, and this first EVA aims to map out a first point of interest outside of the station.

Start time: 9 : 55 AM

End time: 11 : 35 AM

Narrative: We took 18 minutes with Curiosity and Opportunity to go to Compass Rock because we had trouble finding the entry of Galileo Road 1104. Once we were on site, we started the drone and took pictures of the site, and we decided where the checkpoint of the orienteering race will be. The goal will be to evaluate the quality and usefulness of the 3D map.

At 11:10 AM, we headed back to the station and the EVA stopped at 11:35 AM without issues.

EVA #: 08

Purpose of EVA: Exploration and Atmospheric experiments

Maintenance of atmospheric experiments : gathering the data, swapping batteries and restarting the Field Mill. Then exploration from Cowboy corner to Tharsis Montes.

Start time: 9 : 56 AM

End time: 12 : 29 AM

Narrative: We took 2 minutes with Percy and Spirit to go to Marble Ritual. We stopped for the maintenance of the atmospheric instruments, we followed the procedure strictly and without any issue. Afterwards, we took the rover toward Cowboy Corner for 12 minutes. We explored a bit toward the SW. We took a lot of photos and we walked on prominent features.

At 12:06 AM, we headed back to the station and the EVA stopped at 12:29 AM without issues.

EVA #: 09

Purpose of EVA:

Exploration of the Kissing Camel zone. We will start with Robert’s Rock Garden and the West side of the feature. If we still have the time, we will survey the East side but staying in sight of Cow Dung Road.

Start time: 9:51

End time: 11:39

Narrative: We went to Robert’s Rock Garden with the rovers and we started exploring Kissing Camel Ridge W. We walked a lot in the canyon, and took a lot of pictures. We used the drone to take panoramic pictures of the zone. The area was really breathtaking. We also took panoramic view of the station with the drone.

Purpose of EVA: Orienteering for photogrammetry experiment

This maps are created using Drone imagery, and this first EVA aims to map out a first point of interest outside of the station.

Start time: 10 : 30 AM

End time: 12 : 15 AM

Narrative: We went to Compass Rock with Curiosity and Opportunity. Once we were on site, we started an orienteering activity. Gaspard and Adèle searched the points we chose during EVA #7. The activity lasted 30 minutes and then we started using the drone for videos. We gathered interesting datas for the photogrammetry experiment. We couldn’t take a shot while driving the rovers due to a configuration issue but we fixed it after coming back to the station.

EVA #: 12

Purpose of EVA: Maintenance of atmospheric experiments, west of marble ritual

Start time: 9:37

End time: 10:15

Narrative:
Today we got our food resupply dropped in front of the Hab thanks to Mission Support. We began the EVA by picking it up and placing it in the airlock before closing it. We then went to the location of our atmospheric experiments and changed the battery as usual. Because of a small defect on the alimentation system, we have to restart the experiments each time we swap batteries, but it went without any issue.
This EVA was very short on purpose, so that we could focus on the rest of our work in the station.
