STS-125 Mike Massimino points to a friend as he leaves the Operations and Checkout Building with fellow crew mates at the Kennedy Space Center in Cape Canaveral, Fla.
That's one small tweet for a man ... one pretty cool leap for communications.
Astronaut Mike Massimino broke ground Wednesday when he used Twitter to send the first tweet from space.
Checking in as Astro_Mike, he said: "Launch was awesome!! I am feeling great, working hard, & enjoying the magnificent views, the adventure of a lifetime has begun! "
Perhaps the weirdest tweet from Astro Mike came May 10, before he left Earth's terra firma: "Enjoyed my last day on the planet for a couple of weeks with some study, practice, and last minute prep, but mostly trying to relax."
Before Monday's liftoff of Space Shuttle Atlantis to the Hubble Space Telescope, Massimino posted regular updates on his training to the micro-blogging site. He started tweeting in April and by Wednesday, he had about 260,000 followers.
Massimino, who hails from Long Island, New York, said he'll send Twitter updates as time allows during his busy schedule in orbit. He's set to do two of the five spacewalks to repair and upgrade the telescope.
Astronauts can send E-mails from aboard the shuttle but do not have access to the Internet.
So, even if you're "twittered out," you have to admit, these tweets are out of this world.
