Astronaut Jeff Williams, International Space Station (ISS) Expedition 48 commander, recently surpassed former astronaut Scott Kelly for the all-time U.S. endurance record in space – more than 520 days as of Aug. 24. By the time he returns home on Sept. 6, he will have accumulated more than 534 days above Earth over four missions.

Williams surpassed Kelly, who himself took the record from Mike Fincke back in October 2015. Additionally, Williams’ record is expected to be smashed by Peggy Whitson, who is scheduled to stay some 180 days aboard the ISS as part of Expeditions 50 and 51.

Whitson will launch in Soyuz MS-03 in mid-November. She will eclipse Williams’ record sometime in early April. By the time she lands in May 2017, her total will be some 556 days, placing her in the top 10 all-time of any person.

Earlier in the week, Kelly stopped by Mission Control, Houston, to congratulate Williams on surpassing endurance record.

“It’s great to see another record broken, especially by a Sardine,” Kelly said, referencing the fact they are part of the same 1996 NASA class of astronauts. “But I do have one question for you. And my question is, do you have another 190 days in you?”

While Williams broke the all-time endurance record, Kelly holds the U.S. single spaceflight record at 340 days.

Laughing at the question, Williams said that question was not for him.

“That question is for my wife,” Williams said.

In an Aug. 10 in-flight interview, Williams told CBS News he didn’t pay much attention to records, but he reflects about his experience a lot.

“What comes to mind is just the honor of being part of the International Space Station from the beginning all the way through the assembly to now, and working with this great team,” Williams said. “It occurred to me yesterday, I haven’t seen [the ISS] this productive. We’re doing very significant work since we were assembling this thing with a visiting shuttle crew.”

Williams, along with Russian cosmonauts Alexey Ovchinin and Oleg Skripochka, is expected to return to Earth on Sept. 6 (Sept. 7, Kazakhstan time) in Soyuz TMA-20M to finish their 172-day mission. At that time, Williams will move to number 14 on the space endurance list. Number one on that list is Russian cosmonaut Gennady Padalka at 878 days.

Williams’ first mission was aboard Space Shuttle Atlantis in 2000. That was followed by two long-duration flights to the ISS in 2006 and 2010. He launched into space on his current mission back on March 18.
