HOUSTON (PTI): Indian-American astronaut Sunita Williams has taken over the command of the International Space Station (ISS), becoming the second woman in history to do so, even as a three-member crew of the Expedition 32 returned safely to earth, wrapping up a mission lasting more than four months.

The three-man crew onboard a Russian-made Soyuz capsule touched down successfully in central Kazakhstan steppe on Monday morning after spending 123 days at the Space Station.

Just after the Soyuz spacecraft separated from the space station Sunday, NASA astronaut Sunita Williams took over command of Expedition 33 at the station from Commander Gennady Padalka, becoming the second woman in history to do so.

Williams will be sharing the orbital outpost with veteran Russia cosmonaut Yuri Malenchenko and Japanese astronaut Akihiko Hoshide until mid-October, when three more astronauts, including NASA astronaut Kevin Ford, will arrive and round out the full crew of Expedition 33.

"I would like to thank our (Expedition) 32 crew mates here who have taught us how to live and work in space, and of course to have a lot of fun up in space," Williams told Padalka during a change of command ceremony.

Flight Engineer Joe Acaba of NASA, Padalka and Flight Engineer Sergei Revin of the Russian Federal Space Agency, landed in the north of Arkalyk, Kazakhstan on Monday morning.

They arrived at the station on May 17 and spent 125 days in space, 123 of which were aboard the orbiting laboratory.

The trio is expected to have a difficult time readjusting to life on Earth, especially Revin and Acaba, who are coming off their first long-term stay aboard the orbiting international space lab, NASA sources said.

"The goal is to get their strength and all their function back to their preflight baseline," said NASA flight medical officer Steve Gilmore of the rehabilitation programmes the three will undergo. "In 45 days, with folks working hard, typically we get people to where they were before they launched."

Acaba, Padalka and Revin orbited earth 2,000 times and traveled 52,906,428 miles.

Padalka now ranks fourth for the most days spent in space, a total of 711 days during four flights.
