Polar Trek to Mars - Pascal Lee (SETI Talks)
Δημοσιεύτηκε στις 6 Φεβ 2015
Pressurized
rovers are airtight all-terrain motorhomes in which future planetary
explorers will live, work, sleep, and drive during multiple-day
excursions far away from their home base. Although pressurized rovers
are commonly featured in science-fiction lore and technical studies on
paper, there is still very little practical experience with the use of
such vehicles in terrestrial field exploration. Since 2003, the NASA
Haughton-Mars Project (HMP) has begun leading a series of field
simulations of planetary pressurized rover traverses on Devon Island,
High Arctic, a bleak and barren polar analog often described as Mars On
Earth. As stand-ins for pressurized rovers, the HMP uses specially
modified Humvees equipped with living quarters, satellite comms &
nav systems, robotic arms, and spacesuit ports. Rover traverses at HMP
are also set in a true field exploration operations environment in which
dangers, while not as unforgiving as on Mars, are nevertheless real and
relevant.
This talk summarizes the HMP’s experience with
simulated pressurized rover treks to date, and lessons learned for
planning future road trips on the Moon or Mars. Focus is placed on the
HMP’s Northwest Passage Drive Expedition (2009-2011), an epic rover
journey from the continental United States to Mars On Earth, across
hundreds of kilometers of sea-ice along the fabled Northwest Passage.
During the voyage, the expedition crew encountered conditions and
challenges analogous in basic ways to those awaiting future pressurized
rover crews on Mars: hostile environment, dust storm-like blizzards,
uncertain route, treacherous terrain, equipment failure, tight crew
quarters, limited resources, remoteness, and isolation.
While
pressurized rover treks will dramatically expand the range and
productivity of human planetary exploration, they will remain
expeditions within an expedition. If not planned and implemented with
care, they will quickly spell doom for their crews.
