Truthfully, I do find it improbable that Kelly (and all the other pre-menopausal astronauts) wouldn't be on birth control -- especially this long into a co-ed space program. Menstruating in zero gravity seems logistically complex.

And yeah, even if that contraception failed, an abortion seems like the only safe solution?

On the other hand, I listen to the score from Kelly's rescue at least once a week.
