There are questions about existence beyond the planet earth that many people have: Is there life on other planets? What is dark matter made of? Seriously, what is up with that face on Mars?
But none of these hold the mystery, the wonder, the true wonder of discovery as that one age-old question: how will zero-gravity affect the sexytime?
Unfortunately, this will remain unanswered (at least officially), according to NASA Commander Alan Poindexter. In a recent interview, he shot down a reporter's question about potential interstellar hook-ups.
"We treat each other with respect and we have a great working relationship. Personal relationships are not ... an issue," said a serious-faced Mr Poindexter. "We don't have them and we won't."
Now, being a government agency, of course NASA has to show its employees as proper men and women of science and all that. And it's not like there's a whole lot of free room in the International Space Station.
But let's face it, anyone willing to strap themselves into a large piece of metal sitting on top of a bunch of missiles and get fired out past the earth's atmosphere to go hang out in another piece of metal before plunging back to the surface has way more pioneer spirit than the rest of us. And when they need to unwind... well, I'm sure they're not the kind of people to let one Poindexter get in the way.
