Chris Austin Hadfield (born August 29, 1959) is a retired Royal Canadian Air Force colonel, test pilot, and CSA astronaut. As the first Canadian to perform extravehicular activity in outer space, he has flown two Space Shuttle missions and also served as commander of the International Space Station (ISS). Prior to his career as an astronaut, he served in the Canadian Armed Forces for 25 years as an Air Command fighter pilot.

Hadfield has cited part of his career inspiration to have come to him as a child, when he watched the first crewed Moon landing by American spaceflight Apollo 11 on television. He attended high school in Oakville and Milton in southern Ontario, and earned his glider pilot licence as a member of the Royal Canadian Air Cadets. After enlisting in the Canadian Armed Forces, he earned an engineering degree at the Royal Military College in Kingston, Ontario. Hadfield learned to fly various types of aircraft in the military and eventually became a test pilot, flying several experimental planes. As part of an exchange program with the United States Navy and United States Air Force, he obtained a master's degree in aviation systems at the University of Tennessee Space Institute.

In 1992, Hadfield was accepted into the Canadian astronaut program by the Canadian Space Agency. He first flew in space in November 1995 as a mission specialist aboard , visiting the Russian space station Mir. He flew again in April 2001 on , when he visited the ISS and walked in space to help install Canadarm2. In December 2012, he flew for a third time aboard Soyuz TMA-07M to join Expedition 34 on the ISS. When Expedition 34 ended in March 2013, Hadfield became the commander of the ISS as part of Expedition 35, responsible for a crew of five astronauts and helping to run dozens of scientific experiments dealing with the impact of low gravity on human biology. During this mission, he chronicled life onboard the space station by taking pictures of Earth and posting them on various social media platforms. He was a guest on television news and talk shows and gained popularity by playing the ISS's guitar in space. Hadfield returned to Earth in May 2013, when the mission ended. He announced his retirement shortly after returning, capping a 35-year-long career as a military pilot and astronaut. He has five published books including his autobiography, the NYT-bestseller An Astronaut's Guide to Life on Earth.

Early life and education Chris Austin Hadfield was born on August 29, 1959, in Sarnia, Ontario, to Eleanor and Roger Hadfield, who lived in Milton, Ontario. He was raised on a corn farm in Southern Ontario. He was a member of a Wolf Cub Pack that met at the Milton Fairgrounds. He became interested in flying at a young age and in being an astronaut at age nine, when he saw the Apollo 11 Moon landing on television.

Hadfield attended White Oaks Secondary School in Oakville, Ontario, until his senior year and then graduated as an Ontario Scholar from Milton District High School in 1977. As a member of the Royal Canadian Air Cadets, he earned a glider pilot scholarship at age 15 and a powered pilot scholarship at age 16. After graduating from high school in 1978, he joined the Canadian Armed Forces and spent two years at Royal Roads Military College followed by two years at the Royal Military College of Canada, where he received a B.Eng. degree (with honours) in mechanical engineering in 1982. He also conducted his post-graduate research at the University of Waterloo in 1982.

Military service Before graduating from college, he underwent basic flight training at CFB Portage la Prairie. In 1983, he took honours as the top graduate from Basic Jet Training at CFB Moose Jaw, and then went on to train as a tactical fighter pilot with 410 Tactical Fighter Operational Training Squadron at CFB Cold Lake, flying the Canadair CF-116 Freedom Fighter and the McDonnell Douglas CF-18 Hornet. After completing his fighter training, Hadfield flew CF-18 Hornets with 425 Tactical Fighter Squadron, flying intercept missions for NORAD. He was the first CF-18 pilot to intercept a Soviet Tupolev Tu 95 long-range bomber in the Canadian Arctic.

In the late 1980s, Hadfield attended the US Air Force Test Pilot School at Edwards Air Force Base and was the Distinguished Graduate and winner of the Liethen-Tittle Award for the Outstanding Graduate in 1988. He later served as an exchange officer with the US Navy at Strike Test Directorate at the Patuxent River Naval Air Station. His accomplishments from 1989 to 1992 included testing the McDonnell Douglas F/A-18 Hornet and LTV A-7 Corsair II aircraft; performing research work with NASA on pitch control margin simulation and flight; completing the first military flight of F/A-18 enhanced performance engines; piloting the first flight test of the National Aerospace Plane external burning hydrogen propulsion engine; developing a new handling qualities rating scale for high angle-of-attack test; and participating in the F/A-18 out-of-control recovery test program.

In May 1992, Hadfield graduated with an M.Sc. degree in aviation systems from the University of Tennessee Space Institute, where his thesis concerned high-angle attack aerodynamics of the F/A-18 Hornet fighter jet. In total, Hadfield has flown over 70 different types of aircraft.

Astronaut career

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.

He was the director of operations for NASA at the Yuri Gagarin Cosmonaut Training Center (GCTC) in Star City, Russia, from 2001 until 2003. Some of his duties included co-ordination and direction of all International Space Station crew activities in Russia, oversight of training and crew support staff, as well as policy negotiation with the Russian Space Program and other International Partners. He also trained and became fully qualified to be a flight engineer cosmonaut in the Soyuz TMA spacecraft, and to perform spacewalks in the Russian Orlan spacesuit.

Hadfield is a civilian CSA astronaut, having retired as a colonel from the Canadian Armed Forces in 2003 after 25 years of military service. He was chief of robotics for the NASA Astronaut Office at the Johnson Space Center in Houston, Texas from 2003 to 2006 and was chief of International Space Station Operations from 2006 to 2008. In 2008 and 2009, he trained as a back-up to Robert Thirsk on Expedition 21. 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." He noted that he plans to pursue private interests outside government there.

Hadfield is enthusiastic about the prospects for a crewed mission to Mars, and when asked in 2011 if he would consider being the first to visit even if the journey to Mars were one-way, he said "I would be honoured to be given the opportunity."

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.

STS-100

In April 2001, Hadfield served as mission specialist 1 on STS-100, International Space Station (ISS) assembly Flight 6A. The crew of Space Shuttle Endeavour delivered and installed Canadarm2, the new Canadian-built robotic arm, as well as the Italian-made resupply module Raffaello. During the 11-day flight, Hadfield performed two spacewalks, which made him the first Canadian to ever leave a spacecraft and float freely in space. During his first spacewalk Hadfield experienced severe eye irritation due to the anti-fog solution used to polish his spacesuit visor, temporarily blinding him and forcing him to vent oxygen into space. In total, Hadfield spent 14 hours, 50 minutes outside, travelling 10 times around the world during his spacewalk.An Astronaut's Guide to Life on Earth (Hadfield), pp. 86–96.

International Space Station

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. On May 12, 2013, he turned over command of the ISS, and returned home aboard the Soyuz spacecraft on May 13. 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 Hadfield has a social media presence, with over 2,400,000 Twitter followers . He created one of the top Reddit ask me anything (AMA) threads of all time on February 17, 2013. He also maintains accounts on Facebook, Tumblr, and YouTube. His exchanges with William Shatner and other Star Trek actors have received media coverage. Hadfield has been described by Forbes as "perhaps the most social media savvy astronaut ever to leave Earth".

Hadfield enlisted the help of his son Evan to manage his social media presence. They work in tandem to share information over the internet about aspects of life as an astronaut, both the scientific and the mundane.An Astronaut's Guide to Life on Earth (Hadfield), pp. 223–226, 229–231.

Music During his free time on Expedition 35, Hadfield recorded music for an album, using the Larrivée Parlor guitar previously brought to the ISS. The first song recorded in space, "Jewel in the Night", was released via YouTube on Christmas Eve 2012.Hadfield 2013, p. 224.

His collaboration with Ed Robertson of Barenaked Ladies and the Wexford Gleeks, Is Somebody Singing?—sometimes shortened I.S.S.—was aired on the CBC Radio program Q and released by CBC Music online on February 8, 2013. Hadfield sang Is Somebody Singing along with singers across Canada for the national Music Monday program.Hadfield 2013, p. 228. Hadfield has been credited musically on his brother Dave Hadfield's albums. He also sang the "Canada Song" with his brother, released on YouTube on Canada Day, 2014.
