NASA astronauts Suni Williams and Butch Wilmore were on the International Space Station more than nine months, despite launching into space in June for what was expected to be an eight-day mission.

Reaching orbit from NASA’s Kennedy Space Center, the newest crew includes NASA’s Anne McClain and Nichole Ayers, both military pilots; and Japan’s Takuya Onishi and Russia’s Kirill Peskov, both former airline pilots. They will spend the next six months at the space station, considered the normal stint, after springing Wilmore and Williams free.
