EVA #009

Author: Lise Lefauconnier (Leader)

Purpose of EVA: Searching for checkpoints at NorthRidge with a 2D map generated by photogrammetry.

Start time: 8:58

End time: 11:45

Narrative: The goal for this EVA was for a team (Lise and Marie), supervised by Mathurin, to search for checkpoints at North Ridge with a 2D map. The goal was to do it under 3h00, they were done in 1h40. They spent some time taking pictures at the end, and stopped near the atmospheric instruments’ site to put back up the sign that had fallen because of the wind. The wind was higher than expected during the EVA but conditions were still stable to go on with the EVA.
