WASHINGTON, July 28 (Xinhua) -- After 11 days together in orbit, U.S. space shuttle Endeavour undocked from the International Space Station (ISS) on Tuesday, with all of the docked mission's objectives complete, NASA said.
Endeavour separated from the ISS at 1:26 p.m. EDT (1726 GMT), according to NASA.
"It was just a wonderful, wonderful experience to be part of the first crew of 13 people up here and to have representatives from all the international partners, which made it a very special event," shuttle commander Mark Polansky said before the hatches were closed.
"We will miss you," replied the station's skipper, Russian Gennady Padalka. "Have a safe trip."
Endeavour lifts off on July 15 from Kennedy Space Center in Florida after five delays, on a track to the ISS. Landing is set for July 31. Its 11-day mission featured five spacewalks and completed construction of the Japan Aerospace Exploration Agency's Kibo laboratory.
Astronauts also replaced six batteries for the ISS and performed a number of "get ahead" tasks, including tying down some cables and installing handrails and a portable foot restraint to aid future spacewalkers.
Seven more shuttle flights are planned over the coming year to complete the construction of the ISS. The launch of the next shuttle, Discovery, to the ISS is scheduled for the end of next month.
