Being an astronaut I'm sure is a very rewarding and difficult job. You have to be the best of the best to be an astronaut. Sometimes being up in space for long periods can get a little slow and boring. What do you do if you are alone in space to pass the time? How about play a rousing game of baseball which this Japanese astronaut did.....by himself!! Pretty cool as you can see for yourself. Lack of gravity really opens up possibilities for entertainment.
