CAPE CANAVERAL, Fla. (AP) — Space shuttle Endeavour and its crew of six left the International Space Station and headed home to close out NASA’s next-to-last shuttle flight, pausing just long enough Monday to perform a victory lap and test equipment for a future interplanetary ship.

Endeavour looks real nice out there,” space station resident Ronald Garan Jr. called out.

The space station crew beamed down video of the departing shuttle, the last-ever shot of Endeavour in orbit. It was a dark, solitary image against the blue, cloud-covered Earth and grew increasingly smaller.

NASA’s youngest shuttle — the baby of the fleet with just 25 space voyages — is due back in Florida early Wednesday. Its next stop after that will be a museum in Los Angeles for what some consider to be an early retirement.

Endeavour undocked close to midnight Sunday, ending 11½ days of joint flight. The two spacecraft were soaring more than 200 miles above Bolivia when they parted.

By the time they were over Eastern Europe, the shuttle astronauts could see the $2 billion cosmic ray detector they installed on the space station, as well as the new platform holding spare parts.

“We’re the ones that get to see this incredible view, but you’re all with us in spirit, and this is really a new day for science aboard the space station,” Navy Capt. Mark Kelly, the shuttle’s commander, told Mission Control.

Endeavour and its crew left behind a space station that now has a mass of 905,000 pounds and is 100 percent complete, at least as far as NASA’s share of the 12-year project. On the fourth and final spacewalk of the mission Friday, the astronauts attached an extension pole and declared the construction effort over.

The Russian Space Agency still intends to add another compartment or two, but the other partners have all the major items they need already up there for the decade ahead.

Atlantis will make one last supply run to the space station this summer to close out the 30-year shuttle program.

Endeavour’s final job in orbit was to provide a platform for a navigation experiment, designed to assist future spacecraft that may fly to an asteroid or Mars one day. The shuttle and its astronauts hung around a few extra hours to accomplish the task after photographing the station from all sides.

“We’re closing another chapter on the flight,” astronaut Andrew Feustel radioed when the experiment ended. He asked if flight controllers got enough data.

“We’ve got a roomful of happy people down here,” Mission Control replied.

The lead shuttle flight director, Gary Horlacher, praised Capt. Kelly and his crew for their “absolutely flawless” 16-day mission. He wished them “a safe voyage” and said he’d meet them on the runway at Kennedy Space Center.

Capt. Kelly promised to see him there, although he noted that stiff crosswind might postpone the touchdown.
