What was originally meant to be a six-month visit aboard the International Space Station turned into a record breaking extended stay for NASA’s Frank Rubio.
After 371 days, he has now safely returned to Earth, setting a new record for the longest amount of time spent in space by a US astronaut. Russia’s Valeri Polyakov holds the all-time record at 437 continuous days.
Rubio recently told CNN that if he knew his time in microgravity would be twice as long as initially expected, it’s possible he would’ve declined the mission.
