HOUSTON - The space shuttle Atlantis landed back on Earth with its crew of seven astronauts Friday to cap an 11-day mission to the International Space Station.

Atlantis commander Charlie Hobaugh and pilot Barry Wilmore touched down as scheduled at 9:44 am (1444 GMT) at the Kennedy Space Center in Cape Canaveral, Florida amid clear blue skies.

During their successful voyage, the Atlantis crew delivered nearly 30,000 pounds (13,608 kilograms) of spare parts to the orbiting space station, including a pair of gyroscopes, thermal control system components and robot arm gear.
