Missionary position “simply not possible” in zero gravity, says NASA study |
Must admit I’ve never thought of the problems presented by having sex in space, but thankfully the brains at NASA have already done the calculations. We can’t figure out world peace, but we can figure out how let astronauts make love in space.

NASA studied sex in space over 11 years ago according to an article in the guardian.co.uk:
Twenty positions were tested by computer simulation to obtain the best 10, he says. “Two guinea pigs then tested them in real zero-gravity conditions. The results were videotaped but are considered so sensitive that even NASA was only given a censored version.”
Doesn’t sound like we’ll be seeing the instructional Astronauts Do It On The Moon hitting store shelves any time soon. Now if only Paris Hilton had been on the moon, we’d know all about this stuff. Forget the mile high club, that’s for amateurs.
Seriously, I wonder if in my lifetime I’ll have the opportunity to travel into space? Sex would be one of the last things on my mind up there but I can understand how astronauts having to be up there for weeks and months would think about these things.
Where am I going with this post? I’m ejecting now, Houston.




This reeks of a hoax, TD. Since there is no up or down, or top or bottom, on a space ship without artificial gravity, there could be no missionary position, by definition, and it wouldn’t be necessary to go to space to prove it.;-)

Could be. If you locate something that refutes the study let me know. Guardian is a somewhat reliable source. Says they need to have “machines” simulate part of the act.

So many puns to make … so little time …
I don’t see how it would be impossible, the two people would just have to anchor themselves to a wall or floor before getting busy.
Who knew NASA was full of Kama Sutra experts?
I wonder how much someone would pay for a leak of the video of hamsters having sex in zero gravity? I know I’d pay a heck of a lot to see it ..

I won’t be surprised if they actually did that test
because they do test about how life and growth in space
sex should have been covered sometime

For any serious excursions beyond our solar system in the future, reproduction will be a necessary component. More convenient (and fun) if that doesn’t have to be of the test-tube baby variety.
