It's not as memorable as "one small step for man" or "space, the final frontier," but NASA says the first tweet was sent from space today.

From the International Space Station, astronaut T. J. Creamer (@Astro_TJ) wrote:

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

So far, many of the tweets in reply have been along the times of "way too cool dude!"

But here's a question many of us may have wondered about:

rfwhyte: @Astro_TJ I have a simple question. Is weightlessness as fun as I always dreamed it would be? Do you have free time to just PLAY with it?

You can also follow the tweets from space here, NASA says. The space agency says this is all part of a new upgrade that has given astronauts on the space station access to the Web.

CNET News notes, by the way, that:

To be fair, astronauts had tweeted before, but previously they had to e-mail their updates to colleagues on the ground who would then enter them into Twitter. Additionally, messages from unmanned spacecraft have been pushed out onto the microblogging service for some time now. In the summer of 2008, the Mars Phoenix Lander -- for a time, one of the most-followed accounts on Twitter -- triumphantly announced the discovery of ice on Mars.
