Out-of-This-World Sex Could Jeopardize Missions

Sex and romantic entanglements among astronauts could derail missions to Mars and should therefore be studied by NASA, warns a top-level panel of US researchers.

NASA plans to return astronauts to the Moon by 2018 and later on to Mars. But a round-trip mission to the Red Planet would probably last at least 30 months and carry six to eight people. That would be a hotbed for intense crew relationships, says a report by the US National Academy of Sciences (NAS).

"With the prospect of a very long-term mission, it's hard to ignore the question of sexuality," says Lawrence Palinkas, a medical anthropologist at the University of Southern California in Los Angeles, an author of the report. It reviewed NASA's plans for research to keep astronauts safe and healthy in space – but the plans make no mention of sexual issues in spaceflight.

Palinkas says long-term space missions may be similar to extended periods in the isolated and confined environments of Antarctic research stations. He says crews in those stations often pair up in "bachelor marriages" that last the length of their stay – or less. "If there are instances of sexual conflict or infidelity, that may lead to a breakdown in crew functioning," he told New Scientist.

"Breakups can lead to violence and all kinds of things," agrees Carol Rinkleib Ellison, a psychologist specialising in sexuality and intimacy. "People are very primitive in their emotions around partnering and sex."

Palinkas says such problems may be minimised by training astronauts ahead of time in how to deal with stressful situations or by having them speak with psychologists on the ground in group therapy sessions. "You'd deal with it basically the same way you would with any potential crew tension and conflict," he says.

But he says sex may also benefit missions by creating "a sense of stability or normalization." Ellison agrees, saying sex or masturbation could help alleviate boredom and anxiety on the long, lonely journeys through space.

Ellison says NASA should study the likely effects of taking couples up on long missions, as well as issues of sexual orientation and fertility. She suggests individual differences in sex drive could also be used to choose crews for Mars missions.

"One could perhaps select for people who seem to have less need for sex, or at least don't use sex as a form of self-validation," Ellison says.

Beyond that, she adds, NASA should consider the practical issues of out-of-this world sex. "How do you have sex in weightlessness?" she ask. "And there's a lack of privacy – often they're monitoring pulse rate and temperature. I don't know how that would be handled."
