Discovery’s launch has been rescheduled for Friday 28 August at 12.22am EDT (5.22am BST). Wednesday’s launch was postponed after a valve in the shuttle’s main propulsion system failed to perform as expected during fueling of the shuttle’s external fuel tank.
Discovery’s 13-day STS-128 flight to the International Space Station will deliver storage racks; materials and fluids science racks; a freezer to store research samples; a new sleeping compartment; an air purification system; and a treadmill named after comedian Stephen Colbert.
The space shuttle Discover is due to launch on Tuesday 25 August 2009 at 6.35am BST. The fueling of the external tank has started and is a 3 hour process and will provide the fuel required for the 8½ minute journey to orbit.
