The space supply mission closed successfully with space shuttle Discovery landing safely in California.
The weather concerns had prevented its scheduled landing in Florida on Thursday.
The 5.53 p.m. landing at Edwards Air Force base in Southern California marked the end of the two-week mission that brought supplies and equipment to the International Space Station.
The touchdown was originally scheduled for Thursday night at Kennedy Space Centre in Florida, but NASA had to cancel two provisional landing times. The space agency said that the shuttle also had to avoid a piece of space junk on its flight to Earth.
NASA in total had to plan four landing times between Friday night and Saturday afternoon.
NASA generally tries to avoid landing at the site in the California desert because of the high transportation costs to bring the shuttle back to the Kennedy Space Centre.
The ISS crew member Tim Kopra returned back to Earth after 58 days in space with the shuttle Discovery.
The crew of six US and a Swedish astronaut delivered to the ISS a new sleeping compartment and a treadmill, two racks for scientific experiments and a freezer to store experiments set to be sent back to Earth.
One of the racks will be used to conduct research on metals, semiconductors, crystal, glass and other materials in microgravity. The other will be used to study liquids and gels in space.
The astronauts replaced an empty ammonia tank and made other repairs during their three spacewalks.
