Born 19 September 1965 · United States

First woman to fly on a flight test of an orbital spacecraft during the 2024 Boeing Crew Flight Test.

Sunita Lyn Williams is a retired United States Navy captain and former NASA astronaut. Williams served aboard the International Space Station as a flight engineer for Expedition 14, Expedition 15, Expedition 32, and Expedition 71 and commander of Expedition 33 and Expedition 72. A member of NASA’s Commercial Crew program, she became the first woman to fly on a flight test of an orbital spacecraft during the 2024 Boeing Crew Flight Test and had her stay extended by technical problems aboard the ISS for more than nine months. She is one of the most experienced spacewalkers: her nine spacewalks are second-most by a woman, and her total spacewalk time of 62 hours and 6 minutes is fourth overall and the most by a woman.

The Story

1
🚀 In December 2006, Sunita Williams ( @Astro_Suni ) blasted off aboard the Space Shuttle Discovery on mission STS-116, beginning a 192-day stay on the International Space Station that set a new record for women’s time in space at that moment.

In 2012, she commanded Expedition 33 on the ISS, spending 127 days in orbit and completing three spacewalks, each pushing the boundaries of human endurance with nearly 62 hours total spacewalking time accumulated across her career.
3🛠️ Williams piloted Boeing’s Starliner spacecraft on its first crewed flight test in June 2024, a mission that encountered five thruster failures and helium leaks, forcing an extended stay on the ISS that lasted over nine months before safely returning on a SpaceX Crew Dragon capsule.
4She holds the female record for total spacewalk time at 62 hours and 6 minutes, ranking fourth overall among all NASA astronauts, achieved across nine separate spacewalks spanning multiple expeditions.
