Crew 311 EVA Report 10-03-2025

EVA #: 13

Author: Erin POUGHEON (Crew Commander, EVA Leader)

Purpose of EVA: Pick up the salt in front of the Hab. Atmospheric experiments battery change then 3D mapping of Kissing Camel Ridge W with a drone. Before going to Kissing Camel Ridge W, we want to go to Sea of Shells, where we had EVAs last week because we forgot the EVA Emergency Kit over there. We’ll have with us another emergency kit (so we have one with us before picking up the official one), and ropes.

Start time: 09:01 AM

End time: 01:00 PM

Narrative: The EVA started with the Crew going to the atmospheric instruments to change batteries. Everything was nominal. Then, we went to Sea of Shells and picked up the emergency EVA kit that was exactly where we thought we forgot it. The Crew Commander had a problem with her suit, the air flow was stopped. But Crew Scientist and Crew HSO managed to open the suit and fix the problem, it was just one of the cables of the battery that disconnected. We chose to continue the EVA and not abort as the problem was solved, and easy to solve again. We drove back to the station without any problems. We decided to switch rovers as the ones we had were low battery. Then, we drove to KCR W where we performed the photogrammetry nominally. We drove back to the station, entered the airlock at 12:55 AM and entered the station safely at 01:00 PM.

Destination: Marble Rituals, Sea of Shells and then Kissing Camel Ridge W

Coordinates (use UTM WSG 84): 518250 E, 4250750 N then 516500E, 425550 N then 518000 E, 4249500 N

EVA #: 14

Author: Robin GORIUS (Crew engineer, EVA Leader)

Kissing camel study and remapping with a drone due to mistakes made today. Custom small robotic exploration rover photo shoot in front of the hab at the end of the EVA. ESA radar altimeter calibration device inspection as asked by mission support.

Start time: 09:33 AM

End time: 12:45 AM

Narrative: The crew drove to KCR W where we performed the photogrammetry nominally. We drove back to the station and arrived at 12:34AM. We had an issue with perseverance parking brake which didn’t hold the rover when parked at the station. We blocked the rover with rocks before mission support could fix the brake. After we took out a custom built exploration rover out of the airlock to take a picture of it. We quickly took pictures of the ESA radar altimeter calibration device before entering the airlock at 12:45AM and entered the station safely at 12:50AM
