A NASA astronaut made history on Friday by sending the first tweet from outer space. Flight Engineer broadcast directly from the International Space Station:

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

Take that, Neil Armstrong.

The first tweet from space happened thanks to a software upgrade rolled out by NASA this week. The upgrade gave Space Station astronauts direct personal access to the Web -- something never before possible -- using what NASA calls "the ultimate wireless connection." Previously, tweets from astronauts had to be e-mailed down to Earth, then later posted to Twitter by ground-based workers.
