I'm sure a lot of people know this, but I only discovered it today watching Deligracy's newest video...Sims can "listen to Space Woo Hoo" which I guess is their sneaky way of putting in..erm, adult entertainment :s lol that was hard to type out!

Idk if you have to actually have Sims go into space and Woo Hoo first or not, but Deligracy's LP does have an astronaut in the family (there's also one in the household pictured) so you may have to, I'm gonna have to try it next time I fire up the game.
