If you've ever wondered things like this, we're here to help. Below, check out a list of 20 astronauts to follow on Twitter (in no particular order). Veteran commanders and trainees alike, they have a unique perspective on the world—and since they've been in orbit, we mean that literally!
From behind-the-scenes pictures inside the International Space Station to thoughtful answers to your spaceflight questions, these astronauts are a wellspring of insight. It's a shame that so few astronauts tweet regularly—where else can you hear about the final frontier first-hand?
If you have a favorite astronaut on Twitter we've missed, let us know in the comments.
