Jornal Do Brasilia - Russian, US ISS record-holders return to Earth

"The crew of Roscosmos cosmonauts Anton Shkaplerov and Pyotr Dubrov, as well as NASA astronaut Mark Vande Hei, has returned to Earth," Russia's space agency Roscosmos said in a statement.

Footage broadcast from the landing site in Kazakhstan showed the Soyuz descent module touching down at the expected time of 1128 GMT in bright conditions before the crew emerged from the vehicle that had blown onto its side.

"Tasty!" said Shkaplerov, the first man out of the descent module, as he sat sipping a tea provided by recovery staff.

NASA's Mark Vande Hei emerged from the vehicle last, after setting a new record for the single longest spaceflight by a NASA astronaut, clocking 355 days aboard the International Space Station.

Cosmonaut Dubrov, with whom he blasted off from Baikonur in April last year, now holds the record for the longest mission by a Russian at the ISS, although four cosmonauts clocked longer stints at the now-defunct Mir space station, which was the world's first continuously inhabited orbital lab.

Shkaplerov was rounding off a standard six-month mission.

- US, Russia relations in tatters -

Relations between Moscow and Washington have been in tatters since the Kremlin launched an invasion of Ukraine last month, killing thousands and forcing four million people to flee the country.

Space was one of the few areas of cooperation between Russia and the West untouched by the fallout of Russia's annexation of Crimea in 2014, but here, too, tensions are growing.

The ISS, a collaboration between the US, Canada, Japan, the European Space Agency and Russia, is expected to be wound up in the next decade.

Last month, Roscosmos chief Dmitry Rogozin, an avid supporter of what Moscow has called a "special military operation" in Ukraine, suggested that Western sanctions targeting Russia in response had put the orbital lab in jeopardy.

"If you block cooperation with us, who will save the ISS from uncontrolled deorbiting and falling on US or European territory?" Rogozin wrote in a tweet last month -- noting that the station does not fly over much of Russia.

At present, the ISS depends on a Russian propulsion system to maintain its orbit, some 250 miles (400 kilometres) above sea level, with the US segment responsible for electricity and life support systems -- interdependencies that were woven into the project from its inception in the 1990s.

- War opposition -

ISS astronauts and cosmonauts traditionally steer clear of politics, stressing the need for cooperation to further humanity's goals in space.

But at least two retired heavyweights of the space world, US astronaut Scott Kelly and Russia's Gennady Padalka have responded to the invasion with criticism.

Kelly, who held the NASA spaceflight record before it was broken by Vande Hei earlier this month, said he had returned a medal awarded to him by the Russian government in 2011.

"Please, give (the medal) to Russian mothers whose sons have been killed in this unjust war," Kelly said in a tweet addressed to Russia's former president and current deputy security council chairman Dmitry Medvedev earlier this month.

Kelly's former ISS commander Gennady Padalka, also appeared to criticise the invasion in an interview with private Russian media this month.

"One thing is clear to me: authorities, regimes, ideologies come and go, but Russia and Ukraine will always be next to each other. We cannot be separated onto different planets," Padalka told liberal newspaper Novaya Gazeta.

Padalka, 63, holds the world record for cumulative days spent in space -- 879 -- and is a Hero of the Russian Federation.

NASA on Wednesday hailed its own record-breaker, Vande Hei, with the agency's administrator Bill Nelson noting in a statement that his mission was "paving the way for future human explorers on the Moon, Mars, and beyond."
