Walking On The Moon

In the midst of all our Earthly problems the government made the long hoped for announcement that it was going to be a partner in the Lunar Gateway project, a NASA space station orbiting the Moon. We were the first international partner to confirm participation in the program and it will give us the opportunity to not only expand our leadership in space based robotics but also see a Canadian astronaut on the Moon and possibly even Mars. The Canadian space program has an impressive track record of landmark achievements and and this was a very welcome development that will allow us to keep building on our success.

The first time Canada participated in a NASA project was September 29, 1962 when the Canadian built satellite named Alouette was launched into orbit around the Earth. Canada became the 3rd nation, after the U.S. and Russia to design and construct its own satellite. Its mission was to study the ionosphere from above using over 700 radio frequencies and it kept doing this for 10 years. The satellite is still in orbit and will remain so for 1,000 years.

On November 9, 1972 Canada launched the Anik satellites, the world's first national domestic satellites. These geostationary satellites gave Telesat Canada the ability to deliver television to the Canadian North for the first time. Subsequent Anik satellites would deliver radio, satellite TV, broadband Internet and pay TV services.

On November 13, 1981 the Canadarm was launched aboard the Space Shuttle Columbia and made its space test debut while orbiting the Earth. Starting from a Canadian designed robot that could load fuel into CANDU nuclear reactors, a robotic arm that could deploy and retrieve space hardware from the payload bay of the space shuttle was eventually developed. Like a human arm with rotating joints at the shoulder, elbow, and wrist but made from titanium, stainless steel and graphite, it's 15 metres in length, weighs less than 500 kilos but can lift up to 30,000 kilos. After 90 space shuttle flights, and many successful applications over a period of 30 years it was finally retired.

On December 5, 1983 the first 6 Canadian astronauts were selected; Ken Money, Robert Thirsk, Mark Garneau, Steve MacLean, Roberta Bondar, and Bjarni Tryggvasson and, on October 4, 1984 Mark Garneau became the first Canadian in space on board the Challenger. On January 19, 1990 after a hiatus following the space shuttle Challenger disaster in 1986,  Roberta Bondar became the 1st Canadian woman in space on the space shuttle Discovery and, on October 22, 1992 Steve MacLean became the 3rd Canadian in space on board the Columbia.

On June 8, 1992 four more Canadian astronauts are selected to join the team, Mike Mckay, Dave Williams, Julie Payette, and Chris Hadfield. On November 12, 1995 Chris Hadfield became the 4th Canadian in space on the shuttle Atlantis and also the first Canadian to operate the Canadarm (linking Atlantis to the Russian space station MIR) and the first Canadian to visit the Russian space station. On May 19, 1996 Marc Garneau became the first Canadian to fly twice into space, this time on the shuttle Endeavour where he also operated the Canadarm. On July 20, 1996 Robert Thirsk became the 5th Canadian in space on the shuttle Columbia spending 17 days in space, the longest of any Canadian. On August 7, 1997 Bjarni Tryggvasson became the 6th Canadian in space on shuttle Discovery where he tests an anti-vibration system he invented and is now in use on the MIR space station. On April 17, 1998 Dave Williams became the 7th Canadian in space on the shuttle Columbia. On May 27, 1999 aboard shuttle Discovery, Julie Payette becomes the 8th Canadian in space and part of the first crew to dock the shuttle and deliver equipment to the new International Space Station becoming the first Canadian to visit the International Space Station, and the 3rd Canadian to operate the Canadarm. On November 30, 2000 Mark Garneau made his 3rd visit to space with a crew on the Endeavour to install the solar panels on the International Space Station.

Following the success of the original Canadarm the next generation Canadarm2, or Space Station Remote Manipulator System as it's officially known, was developed as a permanent attachment for the new International Space Station. At 18 metres in length and weighing 1,800 kilos it is capable of handling payloads up to 116,000 kilos and is able to assist with docking the space shuttle itself. On April 19, 2001 Chris Hadfield was part of the crew on the shuttle Endeavour who delivered and installed Canadarm2 on the International Space Station and became the first Canadian to do a spacewalk.

On June 5, 2002 Canada's second contribution to the International Space Station the Mobile Base System is delivered by the shuttle Endeavor. A base platform for robotic arms to connect via 4 different power data grapple fixtures, it rests on top of the Mobile transporter rail car. The Mobile Base can glide along the main truss of the International Space Station and access any of 8 work-sites that feature power connections for the Base and its attachments. 

On September 9, 2006 Steve MacLean makes his 2nd space flight and visits the Space Station for the first time on board the shuttle Atlantis to resume assembly of the Space Station following the space shuttle Columbia disaster in 2003. He is the first Canadian to operate the Canadarm2 and Mobile Base System and the 2nd to do a spacewalk. 

On March 11, 2008 "Dextre" the Special Purpose Dexterous Manipulator, a smaller two-armed robot that can attach to Canadarm2 or the Mobile Base System was installed. Designed to handle delicate assembly tasks with smaller arms and power tools this was another Canadian contribution to the Space Station demonstrating our expertise with space robotics. On May 7, 2009 Robert Thirsk launched from Kazakhstan aboard the Russian Soyuz spacecraft and arrived at the International Space Station where he would stay for a record breaking 6 months as part of the first permanent Space Station residents. Then on July 17, 2009 Julie Payette arrived at the Space Station on board the shuttle Endeavour and was welcomed aboard by Robert Thirsk making another first for Canadians as they met in space. With the retirement of the American space shuttle program in 2011 Chris Hadfield on December 19, 2012 returned to space for the 3rd time via a Russian Soyuz spacecraft and became the first Canadian commander of the International Space Station where he stayed for 6 months.

Meanwhile our original Radarsat-1 program launched on November 4, 1995 and updated with Radarsat-2 on December 14, 2007 was the first commercial Earth observation satellite in service and has been providing marine surveillance, ice monitoring, disaster management, resource management, environmental monitoring and mapping services for Canada and around the world ever since as part of the collaboration with the Canadian Space Agency and MacDonald, Dettwiler & Associates, the same folks who brought us the Canadarm technology.

We've come a long way since Alouette and reaped many technological and monetary benefits as a result. Even now we are experimenting with our own version of a Mars Rover and contributing to all sorts of scientific testing on NASA missions to Mars. Mars of course being the ultimate destination in the foreseeable future for Earthlings but, before Canadians get there, we look forward to seeing them walking on the Moon. Which one of the four newest astronauts it will be has yet to be determined but, as of December 3, 2019, David Saint-Jacques has been up in the Space Station via a new Russian Soyuz launch, following the aborted Soyuz failure in October, for a 6 month tour, as Canada's 9th person to be in space.
