NASA astronaut Sunita Williams flew to space for the third time aboard Boeing's Starliner spacecraft but remains in space due to propulsion problems. All eyes are now on their return. Here's everything you need to know about Williams' space timeline and updates:
On December 9, 2006, Sunita Williams flew aboard the space shuttle Discovery on the STS-116 mission to the International Space Station (ISS).
During her stay, she served as a flight engineer for Expeditions 14 and 15.
Williams performed four spacewalks, totaling more than 29 hours, setting a record for women in space at the time.
She spent over 195 days in space during her first mission, a record she held until 2015.
Williams ran the Boston Marathon on the ISS treadmill, covering 42.2 km (26.2 miles).
She was the second American astronaut of Indian heritage to go into space, following Kalpana Chawla.
Williams and the crew of STS-117 landed at Edwards Air Force Base in California on June 22, 2007.
On July 15, 2012, she flew to the ISS again as part of the Soyuz TMA-05M crew.
During her second mission, she completed three more spacewalks, bringing her total to over 50 hours.
Williams completed a triathlon in orbit using a treadmill, stationary bicycle, and weightlifting machine.
In 2015, Williams was selected to make the first test flights in NASA’s Commercial Crew program.
She was chosen for the first crewed test flight of Boeing’s CST-100 Starliner, which launched on June 5, 2024.
Sunita Williams and Butch Wilmore launched on the Starliner capsule on June 5 and were expected back by June 14. However, they are still in space due to propulsion system issues.
Sunita Williams and Butch Wilmore could return by the end of July, according to NASA's commercial crew program director.
