Space travel is a lonely business, and zooming through the cosmos for years at a time takes a huge emotional toll on the body. Astronauts have to sacrifice life’s most simple pleasures while in orbit, like fresh food, hot showers, and, unless Yuri the cosmonaut is feeling particularly frisky, one of the most basic human needs: s-e-x.
Even if you’re lucky enough to be traveling with a willing participant, the logistics of actually doing the deed get complicated. Newton’s law of motion is amplified by zero gravity. For those of you who didn’t pay attention in science class, that means an object in motion will stay in motion unless an external force is applied to it. In terms of space sex, partners bouncing off and away from each other is a serious concern.

The gist? With some very comical hand gestures, deGrasse Tyson explains that ultimately, straps are your friends.
