Astronaut makes first tweet from space

NASA flight engineer T.J. Creamer on Friday made the first ever Twitter post from outer space.

While aboard the International Space Station, Creamer tweeted:

Hello Twitterverse! We r now LIVE tweeting from the International Space Station -- the 1st live tweet from Space! :) More soon, send your ?s

Tweets had been indirectly sent from space before but they had to be e-mailed to ground control before being posted on Twitter. 

House Science and Technology Space subcommittee chairwoman Gabrielle Giffords (D-Ariz.) was proud, retweeting Creamer's message on Friday.

You could say that's one giant leap for mankind.
