EVA Report – February 22nd

Crew 263 EVA Report 22-02-2022

EVA # 1

Author: Cerise Cuny

Purpose of EVA: Initiation EVA, batteries replacement of atmospheric experiments, mapping of station with Augmented Reality, location search for future set up of antenna.

Start time: 9:39

End time: 10:39

Narrative: We checked the rover batteries (all full), and left with Opportunity and Curiosity towards Marble Ritual. We arrived at 9:43, we walked a bit, to see how comfortable we were with the EVA suits, and to get used to them. We took time to admire the Martian landscape. We left Marble Ritual with the rovers at 10:00 to join the atmospheric experiment site. We removed the LOAC because it does not bear snow storms well. We plugged a battery to PurpleAir and re-oriented the anemometer to the North. We had forgotten to bring a garbage bag to protect the battery from the rain ; as it is absolutely necessary to protect it before tonight’s snow storm, we asked our HabCom to put a garbage bag in the air lock. Elena (my buddy) and I went to fetch it while the other two stayed near the weather station to fix some things. We did not lose sight of the other pair and we stayed within the radio range.

When we were done with the atmospheric experiment we went back to the station with the rovers (10:29) and left them there to walk around the station. Nicolas was not able to test the augmented reality to map the MDRS because the HoloLens fell around his neck during the first part of the EVA. We found a nice spot for the communication antenna: far enough from the Science Dome so that it can’t fall on it even in case of extreme winds, but close enough for us to plug its 20m electric cable in the Dome. At 10:39 we were back in the air lock to end the EVA.
