“I’m going to put my spacesuit on, next stop: Earth Orbit!!” he tweeted just yesterday.

Today however, NASA astronaut Mike Massimino, has officially become the first man to Tweet from outer space.

Massimino is one of five astronauts making spacewalks over the span of 11 days to upgrade the Hubble Space Telescope.

NASA has thankfully not placed any limits on what Massimino can Tweet about.  Should be an exciting few days for us all, make sure you’re following him.
