EVA Report – March 13th

Crew 293 EVA Report 13Mar2024

EVA #016

Author: Erin Pougheon (Leader)

Purpose of EVA: Changing batteries of atmospheric instruments and retrieving data, go to Kissing Camel Ridge to search checkpoints with a 3D map, generated with photogrammetry. Pictures will be taken from a drone, put outside by the EVA team

Start time: 8:50

End time: 12:30

Narrative: The EVA started well with the change of batteries at the atmospheric instruments. Meanwhile, a drone pilot took drone pictures of the EVA team and of the station during the first 30 minutes of the EVA, from inside. The EVA team then went to Kissing Camel Ridge and started to search for the checkpoints. One hour into the EVA, one crewmember had a problem with their suit (Suit 5), it turned off. The problem was not identified during the EVA, it seemed to be a circuit issue, not a battery one. The EVA team chose to go on with the EVA with the suit on, but without the helmet, for said crewmember. The EVA team chose to put safety and science first and go on with the photogrammetry experiment, because either way, the helmet had to be taken off to come back to campus, thus simulation was already broken. The EVA team continued to search for checkpoints and came back alright to campus.

Once the EVA Crew was back at the Hab, the Crew Engineer could figure out what the problem was. See Operations report for details.
