NASA video of space shuttle Discovery final launch
A last minute computer glitch almost derailed the thirty-ninth and final launch of the space shuttle Discovery. The ship and its 6 crew did manage to blast off successfully from the Kennedy Space Centre, but with just 3 seconds remaining in its critical launch window. The launch had been delayed for 3 and a half months due to cracks in an external tank. Discovery's final mission will be to deliver supplies and a module to the international space station.
