EVA Report – March 1th

Crew 275 EVA Report 01Mar2023

EVA # 14

Author: Adrien Tison, EVA Leader and Crew Botanist

Purpose of EVA: The purpose of the EVA is to perform the photogrammetry experiments with the 3D map

First, as it is on the way to Candor Chasma, we will change the batteries and collect the data of MegaAres, LOAC, Purple Air, METEO and the Field Mill.

We will then go to Candor Chasma where the two subjects of the experiment will try to find some specific checkpoints, while the operator of the experiment onsite will take time measurements and draw their trajectory on a map. In addition, the two subjects will be equipped with a step counter.

Due to the bad weather conditions (snow), the purpose of the EVA was modified, in agreement with Mission Support, so that very urgent operations could be conducted with our atmospheric instruments.

New purpose of the EVA: Change the batteries and retrieve data from our atmospheric instruments (LOAC, MegaAres, the Weather station, Purple air, and the Field Mill), repatriate LOAC to the Hab.
