Purpose of EVA: Changing batteries of the atmospheric instruments and protecting them from the wind

Start time: 7:58

Narrative: The goal for this EVA was to change batteries of the atmospheric instruments near Marble Ritual. We had difficulties retrieving some data from the instruments but in the end, we succeeded. We turned off LOAC to bring it back to the station due to the weather. We turned off and protected the field mill with protective foams. The wind started to blow hard when we decided to go back to the station because our goals were achieved.

EVA #007

Author: Lise Lefauconnier (Habcom)

Purpose of EVA: Changing the batteries of the atmospheric instruments, searching for checkpoints at NorthRidge with a 3D map generated by photogrammetry. Taking pictures with a drone controlled by a Crew member in the Science Dome for our “Proximars” experiment.

Start time: 8:59

End time: 12:52

Narrative: The EVA team first retrieved data from the atmospheric instruments and changed the batteries. They discovered problems on the atmospheric instruments that they will try to solve in the following EVA. Then they went to North Ridge where the team had to try and find checkpoints with a 3D map generated by photogrammetry, thanks to the previous EVA. The EVA team also set down a drone in front of the Science Dome, it was piloted during the first 30 min of the EVA by a Crew member inside the Science Dome.

Road(s) and routes per MDRS Map: Cow Dung Road, North direction

Modes of travel: Curiosity Rover and Opportunity Rover and walking

Additional notes: Perseverance’s battery was again low so we decided not to take it. Spirit was not at 100% either. Erin’s radio (number 2) died at the end of the EVA (in the airlock). We will check it to see if there is a problem with the radio or if it was just a charging mistake on our side. The team came back at 12:45 and it was sunny outside, so we decided to plug the rovers.
