Purpose:
Measure VNIR reflectance from various lithologic and soil types within
pre-planned survey grid. Return samples from each site for in-Hab
spectral analysis.
Narrative:
Completed engineering EVA (propane, diesel, water checks) prior to science EVA.
Biologist Yususke Murakami and Engineer Victor Luo managed HabCOM.
All EVA crew mobilized on foot to survey grid located 300 meters south of Hab
along Cow Dung Road. XO Heidi Beemer rolled a wheel barrow carrying
survey supplies and equipment,
Scientist Juho Vehviläinen carried sensor and computer, and I
navigated by GPS to the survey grid site.
HSO / Journalist Susan Jewell documented the science EVA with photos and video.
Radio check with HabCOM was established upon arrival at survey grid,
and thereafter on 30 minute regular intervals.
The science survey grid is 60 x 120 meters, and consists of 28 sites
on 20 meter centers established
in 4 rows (A to D, north to south) by 7 columns (1 to 7, east to west).
Survey equipment was first set-up in northeast corner of grid (site A7).
The field team remained together for all survey sites visited today,
first proceeding westward
along row A, back eastward for row B, and westward again to survey
three sites on row C.
Navigating was controlled by pre-selected GPS waypoints.
At all stations geophysical parameters were recorded prior to
systematic VNIR spectroradiometric measurements of in-situ rock and
soil. Rock and soil samples were collected in pre-labeled cloth bags;
samples
are approximately 0.5 kg each. The survey grid is bisected by Cow Dung
Road; therefore the wheel barrow was parked roadside where collected
samples were stowed at each time of road re-crossing, reducing
necessity to carry accumulating samples. 17 of 28 primary sites were
completed before returning again by foot to the Hab.
Upon return to the Hab a final water tank measurement was completed,
and garbage bags placed in
engineering airlock were disposed.
All equipment performed well and radio comms were generally good. We
were reminded by HabCOM to inform them when departing the Hab site for
the field. Some on the EVA team experienced sweating and helmet
fogging.
These conditions were anticipated and manageable. Despite wearing a
tight headband, my glasses rolled down my nose, and I figured a way to
re-prop them by lightly nudging them against the protruding helmet air
vent. XO Beemer’s radio earpiece popped out, due to snagging the loose
radio cord. A reminder to fasten or stow cords appropriately for EVA.
