Hadfield was selected to become one of four new Canadian astronauts from a field of 5,330 applicants in June 1992. Three of those four (
Dafydd Williams,
Julie Payette and Hadfield) have flown in space. The fourth candidate,
Michael McKay, resigned as an astronaut in 1995. Hadfield was assigned by the CSA to the
NASA Johnson Space Center in
Houston, Texas in August, where he addressed technical and safety issues for Shuttle Operations Development, contributed to the development of the
glass shuttle cockpit, and supported shuttle launches at the
Kennedy Space Center, in Florida. In addition, Hadfield was NASA's chief
CAPCOM (capsule communicator
), the voice of mission control to astronauts in orbit, for 25
Space Shuttle missions. From 1996 to 2000, he represented CSA astronauts and coordinated their activities as the chief astronaut for the CSA. In May 2010, Hadfield served as the commander of the
NEEMO 14 mission aboard the
Aquarius underwater laboratory, living and working underwater for fourteen days. NASA announced in 2010 that Hadfield would become the first Canadian commander of the International Space Station, leading
Expedition 35 after its launch on December 19, 2012. His craft docked with the station on December 21. He remained on the station for five months, transferring control to
Pavel Vinogradov and departing on May 13, 2013. In June 2013, one month after completing his third trip to space, Hadfield announced his retirement from the Canadian Space Agency, effective July 3, 2013. Hadfield stated that after living primarily in the United States since the 1980s for his career, he would be moving back to Canada, "making good on a promise I made my wife nearly 30 years ago—that yes, eventually, we would be moving back to Canada."
STS-74 Hadfield served as mission specialist 1 on STS-74 in November 1995. It was NASA's second space shuttle mission to rendezvous and dock with the Russian Space Station
Mir. During the flight, the crew of
Space Shuttle Atlantis attached a five-tonne docking module to
Mir and transferred over 1,000 kg of food, water, and scientific supplies to the cosmonauts. Hadfield flew as the first Canadian to operate the
Canadarm in orbit, and the only Canadian ever to board
Mir.

Expedition 35 on April 30, 2013. He unveiled the $10 banknote on the same day. On December 19, 2012, Hadfield launched in the Soyuz TMA-07M flight for a long-duration stay on board the ISS as part of Expedition 35. He arrived at the station two days later, as scheduled, and became the first Canadian to command the ISS when the crew of Expedition 34 departed in March 2013. He received significant media exposure during his time on the ISS, and ended his time on the station by paying tribute to
David Bowie with a rendition of "
Space Oddity". == Social media ==
