Suni Williams, one of two Nasa astronauts whose 10-day test flight mission turned into a nine-month odyssey on the International Space Station (ISS), has retired from the US space agency.

The 60-year-old former navy captain left in December after 27 years with Nasa, according to a press release from the agency on Tuesday. Jared Isaacman, the agency’s new administrator, praised her as “a trailblazer in human spaceflight”.
