US astronaut breaks record for longest time in space.

Astronaut Frank Rubio will break the US record for the longest time spent in space, staying in orbit for at least 371 days aboard the International Space Station. Rubio's return trip had been slated for this spring, but the spacecraft that carried him and two Russian colleagues sprang a coolant leak in December. Rubio traveled to the space station on a Russian spacecraft as part of a crew-swapping agreement between NASA and Roscosmos. Despite geopolitical tensions, NASA has repeatedly said its partnership with Roscosmos is vital to continuing the space station’s operations and valuable scientific research carried out on board.
