His second and final flight was aboard Endeavour (STS-118) as mission specialist to the International Space Station in August 2007. He performed three EVAs with fellow astronauts Richard Mastracchio and Clayton Anderson for almost 18 hours total.
Tracy Caldwell Dyson, born August 14, 1969 in Arcadia, California, is a veteran of two missions into space. She studied atmospheric chemistry at the University of California, Irvine.
Her first mission was aboard Endeavour (STS-118) as mission specialist in August 2007 to the International Space Station. She celebrated her 38th birthday during the flight.
Her second flight was aboard Soyuz TMA-18 as flight engineer in April 2010. She participated in Expeditions 23 and 24. She returned to Earth in September 2010.
Richard "Rick" Mastracchio, born February 11, 1960 in Waterbury, Connecticut, is a veteran of three space shuttle flights and one trip on a Soyuz spacecraft to the International Space Station.
His first flight into space was aboard Atlantis (STS-106) as mission specialist in September 2000 to the ISS. He operated the Canadarm to move fellow astronauts Ed Lu and Yuri Malenchenko as they performed assembly work on the station.
His second flight was aboard Endeavour (STS-118) as mission specialist in August 2007 to the International Space Station. During the mission he conducted three EVAs, totaling over 18 hours.
Mastracchio's third flight was aboard Discovery (STS-131) as mission specialist in April 2010 to the ISS. He conducted 3 EVAs with fellow astronaut Clayton Anderson totaling around 20 1/2 hours.
His fourth and final flight was aboard Soyuz TMA-11M which launched in November 2013 as part of Expeditions 38 and 39. He performed three EVAs (must be his lucky number!) and returned to Earth in May 2014.
Barbara Morgan, born November 28, 1951 in Fresno, California, went into space aboard Endeavour (STS-118) in August 2007. She had trained as a backup to Christa McAuliffe as NASA's Teacher In Space. She was listed as mission specialist for the mission to the International Space Station.
While in space, she participated in an education event with students at the Challenger Center for Space Education in Alexandria, Virginia (I used to live there!). A few days later, she talked to students at a school in L Ronge, Saskatchewan.
Alvin Drew, born November 5, 1962 in Washington, DC, is a veteran of two space shuttle flights and during his last shuttle mission became the 200th person to walk in space.
His first mission into space was aboard Endeavour (STS-118) as mission specialist in August 2007 to the International Space Station. It was the first flight of the Endeavour after the Columbia disaster. Drew and fellow astronaut Barbara Morgan participated in an education event on August 16 (Day 9) with students in Alexandria, Virginia.
His wake-up songs are two songs I really like: Outa-space by Billy Preston and Learn to Fly by the Foo Fighters.
Drew's second mission into space was aboard Discovery (STS-133) in February-March 2011 to the International Space Station. It was the 39th and final mission of Discovery. It completed a cumulative total of 365 days in space. Drew performed the mission's first EVA on Day 5 with fellow astronaut Steve Bowen. That is when Drew became the 200th person to walk in space.

Mission patch
Space Shuttle Endeavour (STS-118), launched August 8, 2007 to the International Space Station, was the first flight of Endeavour since the Columbia disaster in 2003. Its crew consisted of Commander Scott Kelly, Pilot Charles Hobaugh, Tracy Caldwell, Richard Mastracchio, Dafydd Williams, Barbara Morgan and Alvin Drew.
Barbara Morgan had trained as a backup to Christa McAuliffe as NASA's Teacher in Space, but that ended with the Challenger disaster. However, when Morgan flew on STS-118, she was not considered a Mission Specialist Educator, but rather a Mission Specialist who had once been a teacher. During the mission, she spoke to school children on Earth.
Four EVAs were conducted by Rick Mastracchio, Dafydd Williams and Clayton Anderson, who had arrived on the ISS with STS-117.
Twins Mark Edward Kelly and Scott Joseph Kelly, born February 21, 1964 in Orange, New Jersey, are both astronauts, who were selected by NASA in 1986 and have logged many hours in space.
Mark Kelly is a veteran of four space shuttle flights. His first trip into space was aboard Endeavour (STS-108) to the International Space Station in December 2001 as pilot. His second missin was aboard Discovery (STS-121) also to the ISS as pilot in July 2006. He served as commander on his third flight back on Discovery (STS-124) May-June 2006. His fourth and final flight was on Endeavour (STS-134) as commander May-June 2011. He retired from NASA June 21, 2011 to help his wife, Arizona Congresswoman Gabrielle Giffords, who was critically wounded in an assassination attempt, recover from her injuries.
Scott Kelly has flown two space shuttle missions and set a record in 2015 for the total number of accumulated days. This record was broken the following year by Jeff Williams, and the year after by Peggy Whitson.
His first flight was aboard Discovery (STS-103) as pilot in December 1999, a servicing mission to the Hubble Space Telescope. His second mission was on Endeavour (STS-118) as commander to the ISS in August 2007. He flew to the ISS aboard Soyuz TMA-01M to the ISS with Commander Aleksandr Kaleri and Oleg Skripochka in October 7, 2010. He first served as flight engineer on Expedition 25, beginning the second part of the expedition. He became commander of Expedition 26 which began on November 10, 2010. He returned to Earth March 16, 2011.
His fourth and final mission was on Soyuz TMA-16M launched March 27, 2015 with Mikhail Kornienko, when he began a year-long mission aboard the ISS. He spent 11 months inspace, conducting 3 EVAs before he returned to Earth March 2016 on Soyuz TMA-18M. He was aboard the ISS for Expeditions 43-46. Upon his return, he retired from NASA in April 2016.
He published a book last year Endurance about his time in space.
Charles Owen Hobaugh, born November 5, 1961 in Bar Harbor, Maine, is a veteran of three space shuttle flights. His first flight was on Atlantis (STS-104) in July 2001, when he served as pilot.
He served as pilot on Endeavour (STS-118) in August 2007.
