Crew 280 EVA Report 25-04-2023
Author: Ariadna Farres (HSO & Scientist)
The EVA had the following goal:
Collect some iron-containing rock samples to evaluate its use for Martian batteries by Neus Sabate.
Start time: 2:35 PM
End time: 5:10 PM
Narrative: Before starting the EVA, we received a call from mission support advising us of the possibility of rain in the next few hours. During the whole EVA the astronauts checked the weather, which ended up being windy but with no signs of rain and the mission could be completed.
After performing 5 minutes of depressurization in the front airlock, the EVA team took Spirit rovers and headed White Rock Canyon and Barrainca Butte area to collect iron-containing rocks as suggested by Mission Support Dr. Shannon Rupert.
The EVA team drove very slowly along Cow Dung Road to decrease the discharging rate of the battery rovers. Once they reached the selected area they observed a larger amount of rocks around Barainca Butte. They spent about an hour exploring the area and collecting rocks. At 4:30PM the crew decided to head back to the base, which they reached at 5:10PM. Before entering the Hab, they followed the 5-minutes pressurization protocol.
