Photo of astronaut Reid Wiseman taken by fellow ISS crewmember Barry E. Wilmore.

Here's one for the photo album.

Astronaut Reid Wiseman spent much of the day yesterday on a spacewalk performing maintenance on the International Space Station. His crewmate Barry E. Wilmore snapped this photo. 

Wiseman's amazing Twitter account features daily updates of everything he's seeing up there, including plenty of photos and Vines. I've added some below but he's definitely worth a follow (@astro_reid) if you're of the tweeting disposition.

I don't think I'll ever get over how amazingly cool it is to have astronauts tweeting from space.
