At least 60 search and rescue members volunteered their time to search with dogs for those who had fallen, Buhr said. One had a Korean passport and the others were Korean Canadians. "They didn't do anything wrong", he said.
Shane Kimbrough said during the command ceremony aired on NASA TV that Whitson will also be the first two-time female commander of the ISS. It's just one of many records Whitson is breaking during her mission.
"Up here we don't wear shoes, but Shane is leaving some really big socks for me to fill", replied Whitson.
On April 5, NASA revealed that Whitson was poised to break the record for the cumulative time spent in space by an American astronaut.
Former commander Shane Kimbrough and Flight Engineer Peggy Whitson had the mission to install the thermal shield, but they lost it. NASA didn't explain how this happened, but the piece is indeed gone. During their stay, Kimbrough performed three spacewalks to swap out batteries and fix the outside of the ISS - bringing his total number of career spacewalks to six. MS-02 finally touched Earth at 11:21 UTC near Dzheskazgan town.
Along the way, the astronauts on the space station completed 2,768 orbits of the planet - a voyage of some 73.2 million miles.
"Touchdown! Exp 50 crew lands in Kazakhstan at 7:20am ET after 173 days in space", NASA's page for updates from the International Space Station said in a tweet. 'We get the ability up here to interact with things that actually benefit all of humanity.
