STS-128 To Launch Friday |
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.
