To boldly go… 

Twitter’s world domination shows no sign of abating so what’s next?  Outer-space?  Well yes actually!

Well, let’s keep this strictly accurate, its inner-space (only 200 miles or so up) and although mission STS 125 may mean little to most people its an important mission for NASA and the space shuttle for a number of reasons.

Firstly, it will be the last mission to service the Hubble Space Telescope (HST).  Hubble has been sending incredible images from the depths of the universe since 1994 (thanks to STS-61), and although it has lasted longer than planned, it is due to be replaced, presumably when the credit-crunch has stopped causing so many problems for us earthlings.

Secondly,  this will be the first shuttle flight which will carry a tweeting astronaut!  Yes thats right!  Twitter is boldly going where no other social networking app has gone before!  @Astro_Mike (Mike Massimino) is keeping us in the loop with updates such as ‘just got out of the motion simulator after a morning of shuttle re-entry simulations, we are 19 days from launch’ and Getting ready to put on my white spacesuit, get in the big pool, and practice my first spacewalk with my crewmate Mike Good (nickname Bueno)

I’m quite sure that he’ll have enough buttons to press without having to tap away on his BlackBerry to keep us up to speed, however Mike’s detailed and frequent updates do allow us a real-time peak at one of the most exciting jobs in the world. Godspeed to Mike and all the crew of STS-125.

Mike Massimino (@Astro_Mike) is a NASA astronaut who will be visiting Hubble for the second time, previously flying on board STS-109 in 2002.
