Astronaut dutiesEdit

Selected as an astronaut candidate by NASA in June 1998, he reported for training in August of that year. Training included orientation briefings and tours, numerous scientific and technical briefings, intensive instruction in Shuttle and International Space Station (ISS) systems, physiological training, ground school to prepare for T-38 flight training, as well as learning water and wilderness survival techniques.[2]

Prior to being assigned to a spaceflight, Anderson served as the lead for the Enhanced Caution and Warning (ECW) System development effort within the Space Shuttle Cockpit Avionics Upgrade (CAU) Project. Previously, he was the Crew Support Astronaut for ISS Expedition 4, providing ground support on technical issues in addition to supporting the crew families. Anderson also served as an ISS Capsule Communicator (CAPCOM) and as the Astronaut Office crew representative for the Station's electrical power system. In November 2002, Anderson completed training in the Extravehicular Activity (EVA) Skills program. He was back-up flight engineer for Expedition 12, Expedition 13 and Expedition 14 to the International Space Station.

Anderson served as an astronaut family escort for the STS-107 mission at the request of Rick Husband.[3]

In June 2003, Anderson served as an aquanaut during the NEEMO 5 mission aboard the Aquarius underwater laboratory, living and working underwater for fourteen days.[4] During a NEEMO 5 underwater EVA, Anderson cut his thumb with a knife. The wound was stitched up by hand surgeon and extreme medicine specialist Kenneth Kamler, who was observing the NEEMO project and dove to Aquarius to perform the procedure.[5]

He was a Mission Specialist on STS-131, launched in April 2010. The primary payload of this mission was a Multi-Purpose Logistics Module loaded with supplies and equipment for the International Space Station.

International Space StationEdit

Anderson was a member of the Expedition 15 crew and spent 152 days on board the International Space Station. He launched to the station aboard Shuttle Atlantis as Mission Specialist 5 for the STS-117 mission on June 8, 2007,[6] and remained on board as a member of the Expedition 16 crew before returning to earth aboard Discovery on mission STS-120 on November 7, 2007. On return his official title was Mission Specialist 5.[7] Two of the photos that he took during his July and August 2007 spacewalks were listed on Popular Science's photo gallery of the best astronaut selfies.[8]

Anderson continued a tradition aboard the International Space Station, started by Michael Lopez-Alegria, of conducting daily "trivia" contests with mission control team members on the ground.[9] During Alegria's seven-month stay on the station he would routinely call down movie quotes and challenge the team members to determine the movie the quote was from. Towards the end of his mission he changed to music trivia playing a portion of a song and challenging the team to complete the line. Anderson has taken this tradition and put his own personal twist on it, using the "Book of Answers: The New York Public Library Telephone Reference Service's Most Unusual and Entertaining Questions". Anderson often played song clips for the ground control team, or specific individuals, most notably when he played the song "(Everything I Do) I Do It for You" by Bryan Adams for his wife on her birthday.


Anderson was born in Omaha, but considers Ashland, Nebraska to be his hometown. Married to Susan Jane Anderson (née Harreld) of Elkhart, Indiana. They have two children; a son, Clayton “Cole” and a daughter, Sutton Marie. His mother, Alice J. Anderson, died in December 2007, shortly after his return to earth. His father, John T. Anderson, is deceased.

Like many of the other astronauts and cosmonauts he is a licensed amateur radio operator having passed the technician class license exam in 2001 and was issued the call sign KD5PLA by the Federal Communications Commission on August 13, 2001.[10] During his stay on the ISS in September 2007, he used one of the two amateur radio stations on board to talk with school children.[11]

Anderson is the first and only astronaut from Nebraska and was widely reported in news media as the astronaut rejected fifteen times by NASA before being accepted in 1998. Anderson eventually retired from NASA in January 2013 after serving fifteen years and is now in education.[12]
