EVA Report – November 20th

EVA # 8
Author: Izabela Shopova
Purpose of EVA: Searching for hydrous minerals — clays, sulfates, silica — and/or carbonate salts. Obtaining additional rocks for engineering demonstration (for use with mechanical anchor prototype). Exploring area nearby habitat under alternate lighting.
Start time: 2:45 PM
End time: 4:00 PM
The crew went to explore the area around the Hab and the top of Hab Ridge to search for hydrous minerals. We followed a dried river bed for the first part of the expedition, then turned west and climbed up the side of the ridge. We were able to identify and collect all 3 of the minerals we were searching for. And in addition, we came across a big deposit of seashells at the top of the ridge. After taking photos of the locations of our discoveries, we turned around and walked back to the Hab, taking a longer route to the east. We ended the EVA with a walk around the base and a visual check, confirming that the tunnels and external walls don’t show any new damage, before entering the airlock and completing the EVA.
