A Chronology of Canadian Spaceflight

Canadian astronauts Julie Payette and Robert Thirsk on board the International Space Station, July 2009. NASA photo.

Canada has a rich history as a spacefaring nation. On September 28,1962, Canada became the third country to design and build its own satellite when Alouette 1 was placed in orbit. Ten years later, Canada became the first country to have its own geosynchronous communications satellite with Anik 1. In 1981, the second flight of the U.S. space shuttle tested out the Canadarm or Remote Manipulator System. The Canadarm was a vital part of the U.S. shuttle program until its last flight in 2011.
The Canadian Astronaut Program began in 1983, and on October 5, 1984, Marc Garneau became Canada's first astronaut when he flew aboard Challenger on the STS-41G mission. He was followed into space by Canadian astronauts Roberta Bondar, Steve MacLean, Chris Hadfield, Robert Thirsk, Bjarni Tryggvason, Dave Williams and Julie Payette.
Canada is also contributing to the development of the International Space Station with the Mobile Servicing System, which is helping astronauts build and service the ISS. The first part of this system, Canadarm2, was installed on the ISS in April 2001. The Mobile Base System was added the following year, and Dextre, or the Canada Hand, began operations on the station in 2008.
Canada's history in space is much bigger than the astronauts and the Canadarm. Canada continues to launch communications satellites and other satellites like RADARSAT. In the 1960s, Dr. Gerald Bull spearheaded an effort to launch a satellite with a cannon.
Canadian engineers played a crucial role in the early U.S. human space program. NASA hired 32 engineers from Canada and the United Kingdom when the Canadian government cancelled the CF-105 Avro Arrow program in 1959. These engineers were involved in Mercury, Gemini and Apollo.
The Chronology
October 4, 1957 - The space age began with the launch of Sputnik 1 in the Soviet Union. In Canada that day, the CF-105 Avro Arrow was rolled out for the first time. The Arrow first flew the following March and was cancelled in February, 1959.
January 31, 1958 - Explorer 1, the first U.S. satellite, was launched.
November 8, 1958 - Nike-Cajun sounding rocket launched from Churchill, Manitoba, with the first Canadian payload.
December 31, 1958 - Canada's proposal to build an ionospheric research satellite was submitted to the U.S. National Aeronautics and Space Administration (NASA). The proposal, which was approved by NASA the following March, led to a research program into the ionosphere, a layer of charged particles high in Earth's atmosphere. The ionosphere is of interest to scientists because radio waves are reflected off the ionosphere. The satellite that came out of this proposal was called Alouette.
April 1959 - NASA hired 25 engineers from Avro Canada who lost their jobs when the Avro Arrow was cancelled. Another seven Avro engineers later joined NASA. Although many of this group came from the United Kingdom, the Canadians in the Avro group included Jim Chamberlin, who conceived and designed the Gemini spacecraft, and played key roles in the Mercury, Apollo and shuttle programs, and Owen Maynard, who was one of the key designers and builders of Apollo.
September 5, 1959 - Black Brant 1, the first test vehicle of a line of Canadian built sounding rockets, was launched from Churchill.
April 12, 1961 - Yuri Gagarin became the first human in space when he flew aboard the Soviet spacecraft Vostok 1. The first American astronaut, Alan Shepard, flew his Mercury capsule in a suborbital flight three weeks later.
September 1961 - Dr. Gerald Bull of McGill University in Montreal began the High Altitude Research Program, or HARP. Using a giant cannon based in the Barbados, Bull and his group planned to launch projectiles into space and eventually into orbit. HARP was supported by the Canadian and U.S. governments, but ended in 1967 when the Canadian government withdrew funding.
September 28, 1962 - Alouette 1, Canada's first satellite, was launched atop an American Thor-Agena rocket from Vandenberg Air Force Base in California. With this launch, Canada became the third nation to build its own satellite. Canada's Alouette and ISIS satellites were designed to probe the ionosphere. Alouette was built by the Defence Research Telecommunications Establishment under the leadership of Dr. John H. Chapman.
November 29, 1965 - Alouette 2 launched.
January 30, 1969 - Launch of ISIS 1, which continued the ionospheric research of the two Alouettes.
July 20, 1969 - The Apollo 11 lunar module Eagle landed on the Moon with astronauts Neil Armstrong and Buzz Aldrin on board, the first humans on the Moon. Eagle's four legs, which were made by Héroux Machine Parts Ltd. of Longueuil, Québec, were left behind on the Moon. Five other lunar modules landed on the Moon before Apollo ended in 1972.
September 1, 1969 - The Canadian government created Telesat Canada, a corporation with mixed private and government ownership to operate Canadian domestic communications satellites. Telesat, which launched Canada's Anik, Nimiq and MSAT communications satellites, was privatized in 1993.
March 31, 1971 - ISIS 2, the last of the series, was launched.

May 7, 1975 - Anik A3 launched.
January 17, 1976 - The Communications Technology Satellite or Hermes was launched atop a Delta rocket from Cape Canaveral. Hermes was one of the first satellites to test direct-to-home broadcasting, and was a cooperative venture between the Canadian Department of Communications, NASA and the European Space Agency.
January 24, 1978 - A nuclear powered Soviet satellite, Cosmos 954, re-entered the atmosphere. Parts of the satellite, including radioactive materials, reach Earth in Canada's Northwest Territories. A large military operation recovered the materials.
December 15, 1978 - Anik B launched.
April 12, 1981 - The first flight of the U.S. space shuttle lifted off from Cape Canaveral.
November 12, 1981 - The space shuttle Columbia began the second shuttle flight, the first flight with the Canadarm or Remote Manipulator System on board.

June 30, 2003 - MOST (Microvariability and Oscillations of STars) became Canada's first scientific satellite in more than 30 years when it was launched atop a Rockot launch vehicle from Plesetsk in Russia. The telescope aboard MOST will search for extrasolar planets and information on stars that will help scientists better determine the age of the universe. A tiny nanosatellite called CanX-1 built by University of Toronto students to demonstrate technologies was launched at the same time.
August 12, 2003 - SCISAT, a Canadian-built satellite designed to probe the changes that take place in the ozone layer and other parts of the Earth's upper atmosphere, was launched by a Pegasus booster which was dropped from an aircraft offshore from Vandenberg Air Force Base in California.
July 17, 2004 - Anik F2 launched by an Ariane 5 rocket from Kourou.
August 9, 2005 - The shuttle Discovery completed the STS-114 mission safely after two weeks in space. This first shuttle flight after the Columbia disaster of 2003 featured the first use of a Canadian-built boom extension to the Canadarm that was designed to inspect the shuttle's underside for damage to its insulation tiles. Damage of this type led to the loss of Columbia.
September 9, 2005 - Anik F1R, the first Anik to be built in Europe, launched by a Proton rocket from Baikonur.
September 9, 2006 - Steve MacLean returned to space aboard the shuttle Atlantis on the 12-day mission of STS-115.

Book Review: Canadian Spacewalkers

Canadian Spacewalkers

By Bob McDonald
Douglas and McIntyre

Fifty years ago in March, a hatch opened in a strange looking Soviet spacecraft and for the first time, a human emerged into open space, protected only by a space suit. Cosmonaut Alexei Leonov spent ten minutes outside Voskhod 2, and a few weeks later, American astronaut Ed White spent nearly twenty minutes walking in space outside his Gemini 4 spacecraft.

The half century of spacewalking is being celebrated with a special exhibition at the Smithsonian Institution's National Air and Space Museum, Outside the Spacecraft: 50 Years of Extra-Vehicular Activity

Space-suited astronauts working in open space have long been a staple of science fiction, but the real story of walking in space has taken many unexpected twists and turns.

Both Leonov and White faced great danger due to difficulties getting back into their spacecraft, and later spacewalks in the Gemini program showed that elaborate preparation was needed before every venture outside the spacecraft. Space shuttle astronauts who carried out maintenance and repair work  on satellites such as the Hubble Space Telescope found that the amount of training required to do the job right was even greater than they had expected.

Chris Hadfield became the first Canadian to walk in space in 2001, when he helped install Canadarm2 on board the International Space Station during a mission of the space shuttle Endeavour. Canadian astronauts Steve MacLean and Dave Williams subsequently joined the ranks of spacewalkers during ISS construction missions in 2006 and 2007.

Bob McDonald, the host of CBC Radio's Quirks and Quarks and a longtime space enthusiast, got together with the three astronauts and NASA spacesuit technician Robert Knight to talk about walking in space. The result is a book that gives the reader a real taste of the astronaut experience in gritty detail.

Spacewalking involves a lot of hard work, starting with lengthy rehearsals in gigantic water tanks and virtual reality simulators. Doing fine mechanical work in space wearing a thick inflated gloves is not easy, either. Astronauts exercise their hands and keep their fingernails cut short to prevent injury during the difficult work done inside their space suits.

On his first space walk, Hadfield was nearly blinded when a chemical used to keep his visor from fogging got in his eyes, and this and other problems are discussed.

There is seemingly no question that McDonald is afraid to ask, including the wonders and fears the astronauts experienced outside the airlock, and the matter of passing gas in a space suit. McDonald also spices up the book with his own adventures in simulated space environments.

The stories told by the three astronauts, the technician and the author are contained in a well-illustrated, designed and printed book, which also stands out because so little has been written on the topic of spacewalking.

While there is much more to be said about space walking, including the trials of the early space walkers from both the United States and Russia, and the Apollo astronauts' experiences of walking on the Moon and in deep space, Canadian Spacewalkers has something for anyone who is interested in space exploration, regardless of their nationality.
