NASA mission specialist Michael Massimino is tweeting as he prepares to board space shuttle Atlantis on Monday.
“Putting notes in my flight notebook, making phone calls and trying my best to relax, adrenaline is starting to flow,” Massimino posted 20 hours ago.
One of seven astronauts set to rocket into space to service the Hubble Space Telescope, Massimino is the first spacewalker to use Twitter, giving the world unprecedented personal access into his life before blast off.
With five scheduled spacewalks, the task of fixing defunct science instruments (equipment, which according to NASA wasn’t meant for handling in orbit) and an increased danger to the crew from space junk because of Hubble's extremely high and littered orbit 350 miles up -- Massimino may not have time to micro-blog about his mission. However, for the 193,890 people currently following “Astro_Mike,” receiving the first tweet from outer space would be an experience that’s (pun intended) out of this world.
