CAPE CANAVERAL, Fla.—Astronaut Jeffrey Williams has a new record for NASA under his space belt.

The commander of the International Space Station marked a U.S. recording-breaking 521st day in orbit Wednesday, a number accumulated over four flights. That surpasses the 520-day record set by Scott Kelly, whose one-year space station mission ended in March.

By the time Williams returns to Earth in two weeks to close out his latest half-year trip, he will have logged 534 days off the planet for NASA.

His record won’t last long. Space station veteran Peggy Whitson will top that after she flies up in November for another six-month stay. She’s already at the 377-day mark for total space time, a record for a woman. And even that won’t come close to the world record of 879 days held by Russian cosmonaut Gennady Padalka—a total of 2 ½ years.
