EVA Report – February 10th

Crew 221 EVA Report 10FEB-2020

EVA # 9

Author: Jessica Todd (GreenHab Officer)

Purpose of EVA: We performed a duplicate EVA of this morning’s EVA, trekking over to the North Ridge and up along Hab Ridge to collect 8 samples for microbiology studies. We attempted to follow instructions based on landmarks located by EVA team 1, and follow a designated path from the terrain map. We will be comparing the results of the efficiency, traversing and science of the two EVAs.

Start time: 2:50 pm

End time: 5:09 pm

Narrative: Our EVA team set off from the Hab heading north towards North Ridge. We were aiming for the metal pole marker, indicating the Hab Ridge Rd. We got a little lost at the marker, trying to locate the path, but after a bit of exploring we found the ATV trail that indicated the start of the path up the ridge. We hiked up Hab Ridge, taking samples on the way up, however progress was slow due to one of the EVA team members having a sore knee. Once we reached the top of the ridge, the wind started to pick up, so we turned around and headed back down, taking some more samples on the descent. On the way back to the Hab, one of our radios ran out of charge, so we communicated with hand signals to navigate the path back. We had caught a mouse in the Hab earlier that day, and so with the permission of the mission support team, two EVA members retrieved the trapped mouse from the airlock, swapped out the faulty comms, and headed back out on two rovers. The team member with an injured knee remained behind and finished up their EVA. We drove the two rovers out to Cowboy Corner, let loose Kim the Mouse and returned to the Hab.
