The original claim seems to have been based on an internet hoax.
> All in all, it now looks pretty much indisputable, eight years on and despite his many protestations to the contrary, that Kohler (and by extension, me, and, by further extension, all those who have read and giggled at this story -- written, I hasten to say, by a person in an office in a country which at the time barely knew what the internet was, let alone having reliable access to it or knowing how to use it) have all fallen victim to a particularly fine hoax. The admirable mythbusting Snopes and Urbanlegends websites certainly reckon so, and to prove it supply the fake Nasa document on which the relevant chapter in Kohler's book is based.
There was once a married couple, Jan Davis and Mark Lee who both flew on STS-47, a 7 day mission to Spacelab in 1992.
Not saying sex did happen, but this would be the incident with the highest probability.
My money would actually be on sexual intercourse having happened on Mir, if it happened in space at all. Smaller crew size, and being under the supervision of the slowly failing Soviet Union followed by early Russia surely made it much easier to ignore certain orders than it is on the ISS.
But if it ever happened it hasn't been made public. Not that that's saying much.
I know people who work in mission operations, where they're basically on a Skype call with the ISS all day. Several years ago, there was one astronaut in particular who had to be frequently reminded to cover up. Once they're up there, no one can prevent them from doing what they want, especially if it's their last flight. They're professional in the sense of completing the mission, but they're humans with pilot personalities and nearly zero privacy to begin with.
There was an article in Playboy many years ago that I read (and the search results in that domain are now far too polluted - and yes, I did read the articles) that basically said "either you're going to need a lot of velcro or assistants.
The problem being that every action has an equal and opposite reaction makes certain activities more likely to result in new force vectors which in turn results in velocity that may lead to bumping into things you'd rather not bump while trying to bump uglies.
If the two of you are weightless in the middle of a room shouldn't you remain in the middle of the room so long as you don't throw anything?
Like if you wiggle your arms you won't start to swim through space so as long as your bodies are wiggling then you also shouldn't start to swim? As long as you kick your shoes after before not during it seems to me that there shouldn't be an issue.
You're working on a one body problem there. This is a two body problem where some force applied will cause a transfer of momentum from one body to another. Without something to tether the two bodies together, it is quite likely they'll move apart.
