Sunita Williams is a highly accomplished Indian-American astronaut who has made history in space exploration.
Born on September 19, 1965, in Euclid, Ohio, Williams’s parents are from India, and her mother’s family is from Slovenia.
Williams’ impressive career in space began when she was selected as a NASA astronaut in 1998. She holds the record for the most spacewalks performed by a female astronaut, with four spacewalks during her first mission to the International Space Station (ISS) in 2006.
In 2012, Williams became the first person to complete a triathlon in space, and she also ran the Boston Marathon in space. Her remarkable achievements have earned her numerous awards and recognition, including the NASA Distinguished Service Medal.
Her Latest Mission Aboard Boeing’s Starliner
Williams’ most recent mission was aboard Boeing’s Starliner spacecraft, which launched on June 5, 2024. Initially planned as a short eight-day mission, technical issues forced Williams and her crewmate, Butch Wilmore, to extend their stay on the ISS.

Her Return to Earth
Sunita Williams finally returned to Earth on March 19, 2025, after spending over nine months in space. Her return was initially scheduled for February 2025, but due to delays in launching her replacements, her mission was extended.

Williams, along with fellow astronaut Butch Wilmore, was launched to the ISS aboard Boeing’s Starliner spacecraft on June 5, 2024, for what was supposed to be an eight-day mission. However, technical issues with the spacecraft forced them to stay longer.
Her return was highly anticipated, as she holds the record for the most spacewalks performed by a female astronaut.
Health Challenges Post-Mission
Upon her return, Williams will undergo comprehensive rehabilitation to address the physiological changes caused by prolonged exposure to microgravity. Some of the health challenges she may face include:
- Muscle Atrophy and Weakness: Prolonged microgravity exposure can cause muscle loss and weakness.
- Bone Loss: Microgravity can also lead to bone loss and osteoporosis.
- Vision Impairment: Some astronauts experience vision impairment due to microgravity’s effects on the eye.
