I am currently sitting here in Canada watching Nasa TV live on the internet. Space Shuttle Discovery is set to launch tonight to carry out STS 119. The mission, which is scheduled to last 14 days is Discoverys 36th mission and is set to deliver the final set of solar arrays to the International Space Station (ISS). Once the arrays are installed and operational the ISS will be running at 100% of it’s total power.

The launch is scheduled for 7.43pm EDT  (01.43 GMT) which I know for most of you is too late to watch but if you can stay up then do because a night launch is always a special thing to see.
