First tweet from space

Expedition 22 flight engineer T.J. Creamer posts the first unassisted tweet from the International Space Station. Before this point, all astronauts must email their tweets to Earth before they can be posted. The tweet is made possible by an upgrade that allows the International Space Station to access the World Wide Web.
