Sunday April 22, 2001, is a historic day for Canada. At 7:45 a.m. EDT on Mission Day 4, Canadian Space Agency Astronaut Chris Hadfield becomes the first Canadian astronaut ever to perform a spacewalk as he steps out of Shuttle Endeavour’s airlock with crewmate Scott Parazynski, on the first of two planned EVAs. As the pair donstheir spacesuits, Pilot Jeff Ashby powers up Canadarm (arm 303) and uses it to latch the Spacelab Pallet that contains the folded Canadarm2, a 17-metre robotic arm that will help construct and maintain the International Space Station, to a cradle on the Destiny module.

EVA-1, which lasts 7 hours and 10 minutes, first involves installation of a UHF antenna as well as the installation of cables that provide station power, command, and video to and from the Flight Support Equipment Grapple Fixture on the Pallet. The two spacewalkers then remove the eight metre-long superbolts that secured Canadarm2 during launch. To facilitate the unfolding of Canadarm2, Hadfield, who is riding at the end of Canadarm, which is being lifted by Ashby, pushes Canadarm2 up.

On Mission Day 5, Parazynski uses Canadarm to attach the Raffaello logistics module to a port on the Station’s Unity module. Then on Mission Day 6, Canadarm, again operated by Ashby, is used to support the second spacewalk by Hadfield and Parazynski. EVA-2, lasting 7 hours and 40, the two spacewalkers complete power and data connections on Canadarm2 and disconnect cables on the Spacelab Pallet. On Mission Day 9, Parazynski uses Canadarm to move back the 6 668-kilogram Raffaello module into the cargo bay.

Saturday 28 April 2001 (Mission Day 10) also made history for Canada in space. At 4:44 p.m., Chris Hadfield, aboard Endeavour, commanded Canadarm to grasp the Spacelab Pallet that is held by Canadarm2, operated from inside the Destiny module by Expedition Two member Susan Helms. 18 minutes later, the pallet, which had been used as a launch cradle for Canadarm2, changes hands as this historical handshake between two generations of Canadian space robotics occurs high above British Columbia.

STS-114
July / August 2005
STS-114

STS-114 is the first Return to Flight mission since the tragic loss of Columbia on February 1, 2003. Over two years have been spent researching and implementing safety improvements for orbiters and external tanks. One of the requirements was to inspect the underside of the Shuttle before reentry. To make this possible, MDA of Brampton, Ontario developed an extension to Canadarm to perform on-orbit inspections of the Shuttle's thermal protection system.

During mission STS-114, Canadarm (arm 301) and its extension boom are used to conduct surveys of Space Shuttle Discovery after launch and before landing. The crew uses Canadarm to pick up the new 15-metre Orbiter Boom, and, like a dental mirror, inspect hard-to-reach areas of the Shuttle. The Laser Camera System, one of the two 3-D laser imagers at the tip of the boom, studies the parts of Discovery's wings and nose subject to the most intense heat during reentry for damage.

STS-121
July 2006
STS-121

Mission STS-121, the second Return to Flight mission, aims to demonstrate techniques for inspecting and protecting the shuttle's thermal protection system and to replace critical hardware needed for future station assembly.

En route to the station, the day after launch, Canadarm (arm 301) and its 15-metre orbiter boom sensor system (OBSS) tipped with two types of lasers and a high-resolution television camera are used to inspect key areas of the wings for any sign of damage that may have occurred during launch. Additional inspections using this equipment occur the day before and the day of undocking from the Space Station.

During the first spacewalk, Canadarm and OBSS are tested as a platform for spacewalking astronauts to repair damaged hard-to-reach areas of the orbiter.

STS-115
September 2006
STS-115  flag

Mission STS-115 marks the return to the assembly of the International Space Station. Canadarm (arm 202) and its extension boom are used on flight day two to perform inspection of every inch of the spacecraft for possible signs of damage from the launch.

Canadarm is also used on flight day three to grapple the P3/P4 truss segments and to hand them off to Canadarm2 on the ISS.

After undocking, Canadian astronaut Steve MacLean controls Canadarm to pluck the boom extension out of Atlantis' cargo bay. The crew then conducts a final visual check-up for any possible on-orbit thermal tile damage to the vehicle and sends the images to ground control for inspection.
