Crew 238 EVA Report 10Jan2022
EVA #10
Author: HSO Robert T. Turner
Purpose of EVA: To collect geologic, bacterial and radiation samples.
Start time:12.20
End time: 14.40
Narrative: The MDRS Crew 238 Sol 8 extra-vehicular activity (EVA) went to the region designated Moon Overlook using the Brahe Highway 1575. The surface EVA participants were: Artist Agnieszka Pokrywka, Engineer Simon Werner, and Health / Safety Officer Robert T. Turner.
These utilized rovers Curiosity and Opportunity to transition to
this geological site. EVA objectives were: geological sampling,
survey, and possible radiation measurements; and, a second object was obtaining stream bed samples for possible bacteriological culturing.
This EVA team was designated EVA Team One. Travel to the previously mapped site was completed without incident. Once the two rovers were stationary, exploration was initiated on foot.
This region possessed an appearance quite like luna with gray,
finely-powdered soil, starkly contrasting with an absence of surface stones as had been noted in other EVA sites. This site featured an enormous crater-like structural depression overlaid with a second impact marking. Small stony ejecta was noted in the vicinity of the upper crater rim that was being explored. Several possible evacuation dry stream beds were noted.
Steep gray angular walls descended to smaller chasma-like structures. Samples initially thought to be shock quartz were first noted on this exploration with samples obtained for further study. Extensive surface photography was completed with a more Mars-like demarcation noted on the panoramic views of the vista horizon, including a presumed possible volcanic butte.
Crew member Agnieszka Pokrywka obtained stream bed soil samples for biological investigation. This site had fewer examples of lichen-like lifeforms as noted in the photographic sampling.
Crew members Agnieszka Pokrywka and Simon Werner conducted a walking descent of the crater rim wall into the depth of the crater-like structure, noted changes in the presentation of presumed multiple drainage ravines. Additional surface rock samples were obtained at the descent site, along with supplemental photography. Following completion of an ascent out of this area, all crew members returned to the twin rovers and completed a successful return to the Hab. This ended the planned EVA for MDRS Crew 238, Sol 8, EVA Team One.
