In space, perhaps, no one can hear you Twitter. But on earth, a Tweet from space can have plenty of followers.
NASA astronaut Mike Massimino certainly does – 273,676 of them, in fact – and they follow all his Tweets from space under the name Astro Mike. He’s been sending them since April, transmitted through a radio link from his current home in the space shuttle Atlantis to the Johnson Space Center in Houston, according to Vnunet.
NASA has plans to expand its Twitter use, and Mark Polansky, captain of the next shuttle mission, has already signed up for the service as Astro_127.
