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
