The New Yorker has an interesting feature on what it would take to successful man a mission to Mars. The piece focuses on a University of Hawaii computer-science professor named Kim Binsted and the Hawaii Space Exploration Analog and Simulation, or HI-SEAS program. A dome is set up near the Mauna Loa volcano in Hawaii:
The dome has a porthole, looking across the saddle at Mauna Kea—a legacy of the first study there, during which the benefit of a windowless exterior (protection from radiation) was found to be less significant than the drawback (the crew hated it). For our visit, the porthole had been covered over to keep the crew’s isolation complete. Quiet as parents on Christmas Eve, we ferried tubs of rice cakes and wet wipes from Costco into a back entry porch. Menus had been worked up during two previous missions in the dome, lasting four months each, during which food cooked ad libitum, even from reconstituted ingredients, rated much higher than the kind of meals-in-a-pouch necessary during zero-gravity travel. Back into the truck went black plastic bags of trash and boxes of saltines that had passed their shelf date. “ ‘Principal investigator’ sounds pretty glamorous,” Binsted said, as she climbed behind the wheel. “But a lot of what I do is space janitor.”
The portions describing their exercise routines caught my attention:
Exercise is built into their routine, as it would be for astronauts trying to maintain muscle mass in low gravity (Mars has three-eighths the gravity of Earth), and the chatty exhortations of Tony Horton, the self-described “fitness clown” who devised the P90X workout routine, permeate their conversations. The communication lag means no surfing the Internet, but Zak Wilson, who is twenty-eight, speculated that e-mail, even if it’s time-delayed, will help astronauts feel less isolated than old-time sailors trapped in the Antarctic ice. Wilson brought a 3-D printer, and as he finds himself casting about for useful items to make—iPad wall mounts, a Scotch-tape dispenser—he concedes that watching the extruder swing back and forth, depositing tiny bits of material with each pass, is “maybe not a terrible analogy for our stay here.”
The team even made a video of them doing p90x:
