Satoshi Furukawa, an astronaut with the Japan Aerospace Exploration Agency, played a one-man game of baseball at the International Space Station a few weeks ago. He only managed two outs, but to be fair, he was pitching, batting, and fielding in outer space at the time.
Furukawa, along with two other astronauts, landed safely in Kazakhstan yesterday, where gravity unfortunately makes this kind of baseball impossible.
Note: The video's a little choppy. It was shot in outer space. Also note: Furukawa did not add the Star Trek theme song to his game. That's on us.
