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.
