Three astronauts return to Earth after a year in space. NASA's Frank Rubio sets US space record

A NASA astronaut and two Russian cosmonauts returned to Earth after being stuck in space for just over a year. American Frank Rubio set a record for the longest U.S. spaceflight — a result of the extended stay

A NASA astronaut and two Russian cosmonauts returned to Earth on Wednesday after being stuck in space for just over a year. American Frank Rubio set a record for the longest U.S. spaceflight — a result of the extended stay.

The trio landed in a remote area of Kazakhstan, descending in a Soyuz capsule that was rushed up as a replacement after their original ride was hit by space junk and lost all its coolant while docked to the International Space Station.

What should have been a 180-day mission turned into a 371-day stay. Rubio spent more than two weeks longer in space than Mark Vande Hei, who held NASA's previous endurance record for a single spaceflight.

Russia holds the world record of 437 days, set in the mid-1990s.

The Soyuz capsule that brought Rubio and cosmonauts Sergey Prokopyev and Dmitri Petelin back was a replacement launched in February. Russian engineers suspect a piece of space junk pierced the radiator of their original capsule late last year, midway through what should have been a six-month mission. Engineers worried that without cooling, the capsule’s electronics and any occupants could overheat to dangerous levels, so the craft returned empty.

There wasn’t another Soyuz to launch a fresh crew until this month. Their replacements finally arrived nearly two weeks ago.
