The Boeing Starliner spacecraft successfully completed its uncrewed flight back to Earth, NASA announced overnight. The return ended the Starliner’s most recent flight test months later than intended and leaves its original crew, NASA astronauts Barry “Butch” Wilmore and Suni Williams, aboard the International Space Station until next year.

The Falcon 9 rocket lifted off at 7:03 p.m. local time (2303GMT) from NASA’s Kennedy Space Center in Florida, carrying NASA astronauts Anne McClain and Nichole Ayers, Japan’s Takuya Onishi, and Russian cosmonaut Kirill Peskov to the ISS.
