Suni was commissioned as an Ensign in the United States Navy in May 1987 and served with the US Navy until being selected by NASA in June 1998.

As a member of the Expedition 14 crew, Suni served as Flight Engineer. While onboard, she established a world record for females with four spacewalks totaling 29 hours and 17 minutes of Extravehicular Activity (EVA). Williams concluded her tour of duty as a member of the Expedition 15 crew returning to Earth with the STS-117 crew to land at Edwards Air Force Base, California on June 22, 2007. From July 14 to November 18, 2012, Suni participated in Expedition 32/33. She spent four months conducting research and exploration aboard the orbiting laboratory. She served as Flight Engineer for Expeditions 32 and International Space Station Commander for Expedition 33.

Suni has spent a total of 322 days in space on two missions; ranks sixth on the all-time US endurance list and second all-time for a female. With 50 hours 40 minutes, she also holds the record total cumulative spacewalk time by a female astronaut.
