Sex and Death in Zero-Gravity: NASA Confronts Mission Ethics

With NASA planning to land on Mars 30 years from now, and with the recent discovery of the most "Earth-like" planet ever seen outside the solar system, the space agency has begun to ponder some of the thorny practical and ethical questions posed by deep space exploration.

Some of these who-gets-thrown-from-the-lifeboat questions are outlined in a NASA document on crew health obtained by The Associated Press through a Freedom of Information Act request.

NASA doctors and scientists, with help from outside bioethicists and medical experts, hope to answer many of these questions over the next several years.

"As you can imagine, it's a thing that people aren't really comfortable talking about," said Dr. Richard Williams, NASA's chief health and medical officer. "We're trying to develop the ethical framework to equip commanders and mission managers to make some of those difficult decisions should they arrive in the future."

One topic that is evidently too hot to handle: How do you cope with sexual desire among healthy young men and women during a mission years long?

Sex is not mentioned in the document and has long been almost a taboo topic at NASA. Williams said the question of sex in space is not a matter of crew health but a behavioral issue that will have to be taken up by others at NASA.
