Jeffrey Williams breaks US record as he logs 521 days in orbit

Earlier this year, Scott Kelly launched into the record books after spending the most cumulative days in space for any US astronaut, with 520 days 10 hours and 33 minutes. But as of Wednesday, the torch has been passed to International Space Station commander Jeffrey Williams, who just logged his 521st day in orbit. Williams is the second American to break the record this past year, and he will have spent a total of 534 days away from the planet by the time he returns to Earth.
