Crew 217 EVA Report 11 Dec 2019 Ann Rockett EVA Date: Sol 2, 12-11-19 Start time for EVA: 9:00 am End time for EVA: 12:30 pm Weather was clear and sunny. Purpose of EVA: To investigate the presence of life in water found in potholes study. Green bands sample collection to bring back to lab for analysis and identification. Destination: Lith Canyon Cow dung road Dino quarry at Lith Canyon traveling by rover and on foot EVA Participants: Cynthia, Teresa, Kevin, Ann Narrative: EVA One (Ann, Cynthia, Kevin, Teresa) journeyed to Lith Canyon. One of MDRS’s absolute rules is that one stops when the Rovers’ battery reaches 60%. Do not pass go. Do not collect $200. Do not take the Rover further afield when the battery reads 60%. About two-thirds the way to Lith Canyon, Spirit’s battery read 60%. Not to be deterred, the astronauts continued with their mission, one Rover down. Failure was not an option. They successfully collected water samples from three separate potholes. They also took measured pH and temperature and took salinity readings They also scaped rock samples from four samples from the green sediment in the Morrison strata: one from above the green layer, one from the green layer, one from under the green layer, and one from a group of crystalline structures in the layer above the green layer. Finding themselves with over 60 minutes left in their EVA allotment of time, the group also collected gypsum samples at the Cow Dung Road/Moon Overlook Road junction.
