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.

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