EVA Report – January 12th

Crew 290 EVA Report 12-01-2024

EVA # 06

Author: Madelyn Hoying

Purpose of EVA:

Start time: 1230

End time: 1630

Narrative: After a late start to finish piecing together the necessary science equipment, the EVA crew ventured out for the furthest expedition yet with an ambitious goal to reach Lith Canyon. Unfortunately, the rover batteries reached their limit at about halfway, necessitating a turn-around point near Tharsis Montes. Two diverse sample sites were investigated, with one in a valley between two Morrison Formation hills and another in a dried riverbed heading east into the Tharsis Montes region. Field tests gave clear indications of microbial life at the riverbed site, so the crew is excited to begin lab testing and compare those results to the smectite regions! We successfully used our new method of loading and transporting REMI in the rovers which reduces time spent prepping the robot at our field sites. REMI collected data at 10 different sites, focusing mostly on very aerated red soil and hard sandy riverbeds. REMI burned through both of her batteries during the 4-hour EVA.

Destination: Intended for the southern edge of Lith Canyon; the rover batteries reached 55% (the cutoff) when we were approximately halfway there, so we reached approximately the Tharsis Montes region.
