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.
