Crew 305 EVA Report 16-12-2024
EVA # 08
Author: Ian Pamerleau
Purpose of EVA: Obtain samples on Hab Ridge, take a stream measurement east of Hab Ridge Road, obtain samples near Zubrin’s Head, take two stream measurements east of Zubrin’s Head.
Start time: 12:00 hr
End time: 15:25 hr
Narrative: Ian led the EVA accompanied by Hunter and Spruha. We had planned on testing Hermes around the Hab and in the field, but he was not operational for EVA 08. Instead, we proceeded with the other plans for the EVA. We began by walking north of the Hab along route 1103. Crossing over the flatter lands before the climb to Hab Ridge, Spruha noted that it would be a good place to test her rover on a later EVA. We walked the slope up to Hab Ridge to get some pictures of Factory Butte and the large Mancos Shale exposure to the west. Hunter took some samples of a bleached paleosol that had peculiar red/brown dots throughout the unit along the climb. We then headed east to take a stream measurement of a small flow that was less than 400 m upstream from where we took our first measurement and eventually flows into Candor Chasma. We then walked back to the Hab and loaded our gear into Perseverance and Spirit. Each rover was at 100% battery and had 257.9 hr and 295.8 hr, respectively. We drove the rovers to Zubrin’s Head and parked the rovers where we did for EVA 07. Hunter finished taking paleosol samples from EVA 07. After the samples were done, we walked to the main ephemeral stream east of Zubrin’s Head and took a measurement of a tributary to the north and of the main channel. We then walked back to the rovers and returned to the Hab, noting where we would return for the EVA on Wednesday to Spruha. At the end of the EVA, Perseverance had 88% battery and 258.3 hrs, and Spirit had 88% battery and 296.2 hrs.
