How exactly does someone have sex in space? For years, scientists have wondered if it would be possible to fool around in microgravity. According to VICE, little research has been performed on the subject, nor does NASA have an “official policy on space sex.” Meanwhile, writer Mary Roach reports rumors that it can be done—although since it’s difficult to “stay together,” it helps to involve a third party.  

Turns out, the rest of the world is curious, too. A fan of Neil deGrasse Tyson’s TV show StarTalk asked the famous astrophysicist and science personality if getting it on in space is any different than on Earth. He answers the question in the National Geographic Channel video above—and advises adventurous astronauts to “bring a lot of leather belts” if they want to stay attached while doing the deed.
