A NASA astronaut has caught a Russian ride back to Earth after a US record 355 days at the International Space Station, returning with two cosmonauts to a world torn apart by war.

Mark Vande Hei on Wednesday landed in a Soyuz capsule in Kazakhstan alongside the Russian Space Agency’s Anton Shkaplerov and Pyotr Dubrov, who also spent the past year in space.

Despite escalating tensions between the US and Russia over Vladimir Putin’s war with Ukraine, Vande Hei’s return followed customary procedures.

A small NASA team of doctors and other staff was on hand for the touchdown and planned to return immediately to Houston with the 55-year-old astronaut.

Even before Russia’s February 24 invasion of Ukraine, Vande Hei said he was avoiding the subject with his two Russian crewmates. Despite getting along “fantastically … I’m not sure we really want to go there,” he said.

Doubled the length of their stay

It was the first taste of gravity for Vande Hei and Dubrov since their Soyuz launch on April 9 last year. Shkaplerov joined them at the orbiting lab in October, escorting a Russian film crew up for a brief stay. To accommodate that visit, Vande Hei and Dubrov doubled the length of their stay.

Before departing the space station, Shkaplerov embraced his fellow astronauts as “my space brothers and space sister.”

“People have problem on Earth. On orbit … we are one crew,” Shkaplerov said in a live NASA TV broadcast on Tuesday. The space station is a symbol of “friendship and cooperation and … future of exploration of space.”

The war tensions bubbled over in other areas of space with the suspension of European satellite launches on Russian rockets and the Europe-Russia Mars rover stuck on Earth for another two years.

Vande Hei surpassed NASA’s previous record for the longest single spaceflight by 15 days. Dubrov moved into Russia’s top five, well short of the 437-day, 17-hour marathon by a cosmonaut-physician aboard the 1990s Mir space station that remains the world record.

“Broken records mean we’re making progress,” said NASA’s previous space endurance champ, retired astronaut Scott Kelly, whose 340-day mission ended in 2016.

Like Kelly, Vande Hei underwent medical testing during his long stay to further NASA’s quest to get astronauts back to the moon and on to Mars. He said daily meditation helped him cope during the mission, twice as long as his first station stint four years earlier.

“I’ve had an indoor job 24-7 for almost a year so I am looking forward to being outside no matter what kind of weather,” Vande Hei said in a recent series of NASA videos.
