Sunita Williams Bids Farewell to NASA After a Pioneering Career

Veteran astronaut Sunita Williams has officially retired from NASA after an illustrious 27-year career, bringing to a close one of the most remarkable journeys in modern human spaceflight. Her retirement, effective December 27, 2025, followed a demanding nine-month mission aboard the International Space Station , underscoring her reputation for resilience, leadership, and scientific contribution.

A Trailblazer in Space Exploration

Announcing her retirement, NASA Administrator Jared Isaacman praised Williams as a trailblazer whose leadership aboard the ISS helped shape the future of exploration. Over nearly three decades, she played a pivotal role in advancing space science, station operations, and human endurance in orbit. Her work has been instrumental in strengthening capabilities relevant to the Artemis programme and long-duration missions planned for the Moon and Mars.

Roots, Background and Personal Journey

Born in Euclid, Ohio, Williams identifies Needham, Massachusetts, as her hometown. Her father, a neuroanatomist, hailed from Jhulasan in Gujarat’s Mehsana district before settling in the United States, while her mother, Bonnie Pandya, is of Slovenian origin. Outside spaceflight, Williams is known for her passion for fitness, outdoor activities, home improvement projects, and time spent with her husband Michael and their dogs.

Defining Missions and Historic Records

Williams first flew into space on December 9, 2006, aboard Space Shuttle Discovery on the STS-116 mission, later returning on STS-117 aboard Atlantis. During Expeditions 14 and 15, she served as a flight engineer and set records with multiple spacewalks. In 2012, she launched from the Baikonur Cosmodrome as part of Expeditions 32 and 33 and went on to command Expedition 33, becoming one of the few women to lead the ISS. Her final mission began in June 2024 aboard Boeing’s Starliner for NASA’s Crew Flight Test, which extended unexpectedly to nine months before her return in March 2025.
