NASA astronaut Sunita Williams, a trailblazer for women in STEM and Indian-American space explorers, has retired from the agency after a stellar 27-year career. Her retirement comes while she is currently serving aboard the International Space Station (ISS) as part of Boeing’s historic first crewed Starliner mission.
A Record-Setting Career
Selected as an astronaut in 1998, Williams flew on two long-duration ISS missions. She amassed a total of 322 days in space, setting the record for the most cumulative spacewalk time by a woman—an incredible 50 hours and 40 minutes across seven spacewalks.
“Sunita Williams is a distinguished veteran of two long-duration spaceflights and a former commander of the International Space Station. She is a trailblazer for women in STEM and for American astronauts of Indian heritage. I wish her all the best in her next endeavour,” said NASA Administrator Bill Nelson.
Historic Missions and Command
Williams served as a flight engineer on Expedition 14/15 in 2006. She later returned to the ISS in 2012, serving as a flight engineer on Expedition 32 and taking command of Expedition 33. Her career highlights the growing role of women in commanding complex space missions.
The Starliner Mission
Marking a new chapter in her career, Williams launched on June 5, 2024, as the flight engineer for the first crewed flight test of Boeing’s Starliner spacecraft. She is currently aboard the ISS for Expedition 71, wrapping up her service as the spacecraft remains docked.
Early Life and Naval Career
Born in Euclid, Ohio, Williams is a graduate of the US Naval Academy. She was commissioned into the US Navy in 1987, where she trained as a helicopter pilot and later a test pilot before retiring from naval service in 2007. She also holds a Master’s degree in Engineering Management.
Following in the footsteps of Kalpana Chawla, Sunita Williams’ retirement closes a major chapter in human spaceflight, leaving a legacy of endurance, leadership, and inspiration.
