Sunita Williams
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.
🔔 Add birthday reminderSunita 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.
✨ A detail that surprised us
In 2007, Sunita Williams became the first person to run a full marathon in space, completing the Boston Marathon on a treadmill aboard the ISS while her sister ran the race on Earth simultaneously.
1. 🚀 In December 2006, Sunita Williams 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.
2. 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.
4. She 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.
5. 🌍 Born in 1965 in Ohio to an Indian neuroanatomist father and a Slovenian-American mother, Sunita carried a samosa and Carniolan sausage into space, celebrating her multicultural roots in an orbiting microcosm far from Earth.
6. Before becoming an astronaut, Williams was a U.S. Navy helicopter pilot, flying H-46 Sea Knight helicopters in Operation Desert Shield and Hurricane Andrew relief, and later became an instructor at the Naval Test Pilot School by 1995.
7. 🏃 While aboard the ISS in 2007, she ran the Boston Marathon on a treadmill in zero gravity, finishing in 4 hours and 24 minutes, synchronizing with her sister running the same race back on Earth.
8. ❓ How did Sunita Williams’ extended stays on the ISS, including her survival through spacecraft technical failures, influence NASA’s approach to long-duration space missions and commercial crew safety protocols?
