X 37B Spacecraft Returns After 7-Month Trip

X 37B Spacecraft Returns After 7-Month Trip:VANDENBERG AIR FORCE BASE, Calif. — The U.S. Air Force's secrecy-shrouded X-37B unmanned spaceplane returned to Earth early Friday after more than seven months in orbit on a classified mission, officials said.

The winged craft autonomously landed at at Vandenberg Air Force Base on the California coast 130 miles northwest of Los Angeles, Vandenburg spokesman Jeremy Eggers said.

"It's very exciting," Eggers said of the 1:16 a.m. PST landing.

The X-37B was launched by an Atlas 5 rocket from Cape Canaveral, Fla., on April 22, 2010, with a maximum mission duration of 270 days.

Also known as the Orbital Test Vehicle, the Boeing-built spacecraft was originally a NASA project before being taken over by the military.

The Air Force has not said whether it carried anything in its cargo bay, but insists the primary purpose of the mission was to test the craft itself.

"We are very pleased that the program completed all the on-orbit objectives for the first mission," program manager Lt. Col. Troy Giese said in a statement.

"Today's landing culminates a successful mission based on close teamwork between the 30th Space Wing, Boeing and the Air Force Rapid Capabilities Office," Giese said.

Eggers said the craft is expected to return to space next year.
