DZHEZKAZGAN, Kazakhstan — Two NASA astronauts and a Russian cosmonaut returned to Earth on Wednesday, rounding off a mission of more than five months aboard the International Space Station.

Alexander Misurkin of Russia’s Roscosmos space agency and NASA’s Mark Vande Hei and Joe Acaba touched down on steppe land southeast of the town of Dzhezkazgan in central Kazakhstan at the expected time of 0231 GMT.

Misurkin, 40, who handed over command of the International Space Station to compatriot Anton Shkaplerov Tuesday and took charge of the Soyuz descent module carrying the trio down to Earth has spent 334 days in space over two flights.

Acaba, 50, is completing his third mission having racked up some 10 months in orbit, while 51-year-old colleague Vande Hei was in space for the first time.

Both NASA astronauts were active on Twitter while aboard the ISS, while Misurkin eschewed the micro-blogging platform.

Puerto Rican native Acaba on Sunday tweeted a photo of his hands framing the Earth as viewed from the ISS’s famous “Cupola” observation module.

“The future of our home is in all of our hands. May we all care for #Earth and practice good stewardship,” he wrote.

Ex-military man Vande Hei shared his love of sports, taking in both the American football Superbowl and the Pyeongchang Winter Olympics while aboard the orbital lab.

NASA stopped its own manned launches to the ISS in 2011 but recently moved to increase its crew complement aboard the ISS as the Russians cut theirs in a cost-saving measure announced last year.

Roscosmos will replenish its crew once a new, multi-purpose space module called Nauka docks at the ISS, but the launch of the module has been delayed several times and is now not expected to take place before 2019.

The ISS laboratory, a rare example of American and Russian international cooperation, has been orbiting Earth at about 28,000 kilometres per hour (17,000 miles per hour) since 1998. — AFP
