EVA Report – January 11th



Crew 272 EVA Report 11-01-2023

EVA # 8

Author: Arly Black

Purpose of EVA: Exploratory EVA to Hab Ridge, initial scouting of geologic setting.

Start time: 2:00 PM

End time: 4:15 PM

Narrative: Due to unpredictability in the weather and rover charging mishaps, today’s EVA reverted to Plan B: hike to Hab Ridge and explore the area without any preconceptions of what to expect. This time, no rovers were harmed in the making of the EVA. The crew walked from the Hab along road 1103 towards North Ridge. They took a left and walked towards Hab Ridge Road. Along the way, the curious traveler stopped to collect samples and examine their surroundings. They then continued on towards Hab Ridge Road, which runs north and south and lies to the west of the Hab, where they found a ridiculous amount of “devil’s toenails” (a genus of extinct oysters, also known as Gryphaea). They walked until they reached the repeater (it’s still standing!) and were able to see our glorious Hab off in the distance. This was the goal of the mission and therefore mission success was achieved! The crew did note that this EVA required more skillful map reading than any other EVA so far.

As this was an exploratory mission, the crew used the experiences from this EVA to brainstorm ideas for future EVAs (but only two days of EVAs left ☹!!!). Adriana examined the geological environment and tried to see how well defined the strata were in that location and what kinds of fossils were present. She was not expecting to see that many toenails which is indicative of an ancient marine environment in that area (or many giants with nail clippers). She is interested in investigating what they have been preserved in. The strata are not well defined along Hab Ridge Road, and it is difficult to see the contact between formations.

On their way back to the Hab, Adriana did some more digging, as one does, and was excited to find even MORE toenails – who wouldn’t be?! Many photos were taken to document the area and they trundled on back to the Hab along the same route. Well done explorers! But leave those toe clippings off the kitchen table, would ya?
