NASA astronaut Peggy Whitson returns to Earth after completing a record-breaking 288-day long mission, the US space agency said on Sunday. Whitson, along with fellow Expedition 52 Flight Engineer Jack Fischer of NASA and Commander Fyodor Yurchikhin of the Russian space agency Roscosmos undocked their Soyuz MS-04 spacecraft from the International Space Station and landed in Kazakhstan at 9:22 pm EDT.
On Friday, Yurchikhin handed over station command to NASA’s Randy Bresnik.
Whitson completed a 288-day mission that began in November 2016, spanning 122.2 million miles and 4,623 orbits of Earth her third long-duration stay on the outpost. At the time of their landing, she has accrued a total of 665 days in space over the course of her career, more than any American astronaut, placing her eighth on the all- time space endurance list.
Yurchikhin and Fischer, who launched in April, completed 136 days in space. Yurchikhin returned to Earth with a total of 673 days in space on his five flights, putting him in seventh place on the all-time endurance list.
As a result of the impacts of Hurricane Harvey, NASA is reviewing return plans to Houston of Whitson, Fischer and the science samples landing in the Soyuz spacecraft.
The crew will participate in standard post-flight medical evaluations.
At the time of undocking, Expedition 53 will begin aboard the station under the command of Randy Bresnik.
Along with his crewmates Sergey Ryazanskiy of Roscosmos and Paolo Nespoli of ESA (European Space Agency), the three- person crew will operate the station until the arrival of three new crew members.
Mark Vande Hei and Joe Acaba of NASA and Alexander Misurkin of Roscosmos, are scheduled to launch on September 12 from Kazakhstan.
