EVA Report #4 – April 15th

Crew 245 EVA Report 15-04-2021

EVA #4

Author: Shayna Hume, Executive Officer

Purpose of EVA: Science & Operations EVA. Firstly, we wanted to take soil samples at a ridge geological location, and we wanted to identify an emergency shelter location at the same.

Start time: 09:30 nominal.

End time: 12:30 nominal, 11:30 actual after a return from inclement weather.

Narrative: We left for the EVA promptly, Hume and Hariharan on rover and Hernandez on ATV 1. After a brief time, Hume identified a honk behind us, and we were able to pull to the side of the road and notice a “breaking sim” Truck behind us, trying to pass us. They did so. We continued and quickly arrived at the stopping coordinates on the road. We found a smooth path down to what seemed a streambed adjacent to the ridge we were targeting. We immediately identified an emergency shelter location and took notes on it. After that, we found three soil locations on the ridge itself. Upon seeing darker clouds, we immediately began to head back. By the time we were at the vehicles, the wind was extremely high. When we got back into radio range, we found out that the Habcomm had already been asked to emergency return us to shelter. We were back and done with the 5-min airlock duration by approx 11:30.
