Scientists Emerge After Eight-Month ‘Trip to Mars’

2 minute read

Six scientists tasked with simulating life on Mars emerged on Saturday after eight months living under a dome located 8,000 feet above sea level in a dormant Hawaii volcano.

The six were part of a human performance study funded by NASA and had not left the dome without a spacesuit on since entering the study almost a year ago. Operating in complete isolation, the scientists were monitored by surveillance cameras, body-movement trackers and electronic surveys to track how they worked as a team.

Rover tracks disappear toward the horizon like the wake of a ship across the desolate sea of sand between the craters Endurance and Victoria on the Meridiani Plains.

A false-color image of Endurance Crater. In this image, tendrils of sand less than 3.3 ft (1 m) high extend from the main dune field toward the rover. Dunes are a common feature across the surface of Mars. Before the rover headed down to the dunes, mission managers first established whether the slippery slope that led to them was firm enough to ensure a successful drive back out of the crater. Otherwise, the dune field would become a sand trap. NASA—JPL-Caltech / Cornell University

Nicknamed "blueberries" by mission scientists, the little pellets are actually hematites, an iron oxide typically formed in standing water—of which Mars once had plenty.NASA—JPL-Caltech / Cornell / USGS / Cathy Weitz

The piece of metal with the American flag on it is made of aluminum recovered from the site of the World Trade Center towers in New York City. It serves as a cable guard for Spirit’s rock abrasion tool as well as a memorial to the victims of the September 11, 2001, terrorist attacks. Opportunity has an identical piece.Image Number: PIA05221Credit: NASA/JPL-Caltech/Cornell University

“Astronauts are very stoic people, very level-headed, and there’s a certain hesitancy to report problems,” University of Hawaii professor Kim Binsted, principal investigator for the study, told the AP. “So this is a way for people on the ground to detect cohesion-related problems before they become a real issue.”

To release stress, the crew members could use a treadmill or stationary bike–only on sunny afternoons, however, because both were solar powered. Their diet consisted mainly of freeze-dried chili.

Mauna Loa was a prime site for the study because of its terrain and silence. When looking out the dome’s porthole windows, the scientists could only see lava fields and mountains.
