CAPE CANAVERAL, Fla., Aug. 29 (UPI) -- Space Shuttle Discovery left the launch pad just before midnight Friday -- four days behind schedule -- for its trip to the International Space Station.
The shuttle is on a 13-day mission to the International Space Station, where it will deliver supplies, research equipment and a new flight engineer, Nicole Stott, The New York Times reported. She will replace Army Col. Timothy Kopra.
Discovery launched at 11:59 p.m. from the Kennedy Space Station at Cape Canaveral. Weather and problems with a liquid hydrogen valve delayed the launch, originally scheduled for Tuesday.
The shuttle, under the command of Marine Col. Frederick W. Sturckow, is scheduled to dock with the space station about 9 p.m. Sunday. Undocking is scheduled Sept. 8 and landing two days later.
The payload includes a new carbon dioxide removal system and sleep crew station for the space station, an ammonia coolant system tank and a treadmill named after Steven Colbert of "The Colbert Report."
