Sunita Lyn "Suni" Williams née Pandya(born September 19, 1965) is an Indian American astronaut and a United States Navy officer who holds the record for longest space flight by a woman 321 days 17 hours 15 minutes. She was assigned to the International Space Station as a member of Expedition 14 and Expedition 15. In 2012, she served as a flight engineer on Expedition 32 and then commander of Expedition 33. In addition to holding the record for the longest single space flight by a woman she holds the record for number of spacewalks for a woman, and most spacewalk time for a woman. Williams broke the latter two records, then held by Kathryn Thornton, during Expedition 14/15 in 2007, but both records were surpassed by Peggy Whitson during Expedition 16. Williams regained both records during her sixth spacewalk, on September 5, 2012, and currently has 50 hours and 40 minutes of spacewalk time (seven walks).
