Astronaut Sunita L. Williams, STS-116 mission specialist, participates in the mission's third planned session of extravehicular activity (EVA)
Sunita Williams began her Astronaut Candidate training at the Johnson Space Center in August 1998.Following are the space mission undertaken by Sunita Williams[4]
STS-116Edit
Williams was launched to the International Space Station (ISS) with STS-116, aboard the Space Shuttle Discovery, on December 9, 2006, to join the Expedition 14 crew. In April 2007, the Russian members of the crew rotated, changing to Expedition 15. Among the personal items Williams took with her to the ISS were a copy of the Bhagavad Gita, a small figurine of the Hindu deity Ganesha, and some samosas.[9]
Expeditions 14 and 15Edit

Williams became the first person to run a marathon from the space station on April 16, 2007
After launching aboard the Shuttle Discovery, Williams arranged to donate her pony tail to Locks of Love. Fellow astronaut Joan Higginbotham cut her hair aboard the International Space Station and the ponytail was brought back to Earth by the STS-116 crew.[10] Williams performed her first extra-vehicular activity on the eighth day of the STS-116 mission. On January 31, February 4, and February 9, 2007, she completed three spacewalks from the ISS with Michael López-Alegría. During one of these walks, a camera became untethered, probably because the attaching device failed, and floated off to space before Williams could react.[11]

Sunita L. Williams and Joan E. Higginbotham refer to a checklist as they work the controls of the Canadarm2 in the International Space Station's Destiny laboratory
On the third spacewalk, Williams was outside the station for 6 hours and 40 minutes to complete three spacewalks in nine days. She has logged 29 hours and 17 minutes in four spacewalks, eclipsing the record held by Kathryn C. Thornton for most spacewalk time by a woman.[4][6] On December 18, 2007, during the fourth spacewalk of Expedition 16, Peggy Whitson surpassed Williams, with a cumulative EVA time of 32 hours, 36 minutes.[12][13] In early March 2007, she received a tube of wasabi in a Progress spacecraft resupply mission in response to her request for more spicy food. When she opened the tube, which was packaged at one atmospheric pressure, the gel-like paste was forced out in the lower pressure of the ISS. In the free-fall environment, the spicy geyser was difficult to contain.[14]
On April 26, 2007, NASA decided to bring Williams back to Earth on the STS-117 mission aboard Atlantis. She did not break the U.S. single spaceflight record that was recently broken by former crew member Commander Michael López-Alegría, but did break the record for longest single spaceflight by a woman.[4][15][16] Williams served as a mission specialist and returned to Earth on June 22, 2007, at the end of the STS-117 mission. Poor weather at the Kennedy Space Center in Cape Canaveral forced mission managers to skip three landing attempts there over previous 24 hours. They then diverted Atlantis to Edwards Air Force Base in California, where the shuttle touched down at 3:49 p.m. EDT, returning Williams home after a record 192-day stay in space.
