NASA's space shuttle Discovery, with seven-astronaut crew, successfully landed at Edwards Air Force Base in California amid sunny sky after bad weather prevented its return to the Kennedy Space Center in Florida.

NASA wanted the shuttle to land in Florida in a bid to save the trouble and expense of ferrying them back to the Kennedy Space Center.

The mission completed its 13 day-mission to the International Space Station designed to equip ISS with latest equipments including life support gear and scientific gadgets costing around 18,000 pounds.

The crew members conducted three spacewalks during their mission concluding some repair work and adding new equipments like external cooling system. It also collected some material helpful for developing future spacecraft.

Shuttle communicator Eric Boe said from the mission control, "Welcome home, Discovery. Congratulations on an extremely successful mission."

American astronaut Tim Kopra, who spent 58 days abroad the ISS, has termed the experience as absolutely phenomenal in his life. All astronauts including five Russian, European and Canadian members will remain under doctor's observation until late November.
