To make this possible, MacDonald, Dettwiler and Associates Ltd. One of the requirements was to inspect the underside of the Shuttle before reentry. Over two years have been spent researching and implementing safety improvements for orbiters and external tanks. STS-114 is the first Return to Flight mission since the tragic loss of Columbia on February 1, 2003. Two days after EVA-2, Forrester uses the Canadarm to carefully remove the Leonardo logistics module from the Station and place it back in Discovery's cargo bay. During EVA-2, a spacewalk that lasts 5 hours and 29 minutes, Barry and Forrester successfully strings two 45-foot heater cables and installs handrails down both sides of the Destiny module. EVA-1, an excursion that lasts 6 hours and 16 minutes, involves installing the Early Ammonia Servicer and the first external experiment, a materials samples exposition experiment called MISSE, on the Station's hull. On EVA-2, a spacewalk that lasts 6 hours 29 minutes, Gernhardt and Reilly install three high-pressure gas tanks onto the Quest airlock.ĭuring this second ISS crew exchange mission (Discovery brings to the Station Expedition Three members Frank Culbertson, Vladimir Dezhurov and Mikhail Turin to replace Expedition Two members Yuri Ussachev, Susan Helms and Jim Voss), the Canadarm, first operated by Mission Specialist Pat Forrester, is used to lift the Leonardo supply vessel and attach it onto the Unity node.ĭiscovery's Commander Scott Horowitz later operates theCanadarm to support two spacewalks by astronauts Dan Barry and Pat Forrester. During EVA-1, Gernhardt and Reilly assist Canadarm2 operator Susan Helms with the installation–the first operational mission of the Canadian station manipulator–of the Quest joint airlock onto the Station's Unity node. The Canadarm, operated by Mission Specialist Janet Kavandi, is used to support two of three spacewalks by astronauts Michael Gernhardt and James Reilly. 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. At 4:44 p.m., Chris Hadfield, aboard Endeavour, commanded the Canadarm to grasp the Spacelab Pallet that is held by Canadarm2, operated from inside the Destiny module by Expedition Two member Susan Helms. Saturday 28 April 2001 (Mission Day 10) also made history for Canada in space. On Mission Day 9, Parazynski uses the Canadarm to move back the 6, 668-kilogram Raffaello module into the cargo bay. EVA-2, lasting 7 hours and 40, the two spacewalkers complete power and data connections on Canadarm2 and disconnect cables on the Spacelab Pallet. Then on Mission Day 6, the Canadarm, again operated by Ashby, is used to support the second spacewalk by Hadfield and Parazynski. On Mission Day 5, Parazynski uses the Canadarm to attach the Raffaello logistics module to a port on the Station's Unity module. To facilitate the unfolding of Canadarm2, Hadfield, who is riding at the end of the Canadarm, which is being lifted by Ashby, pushes Canadarm2 up. The two spacewalkers then remove the eight metre-long superbolts that secured Canadarm2 during launch. As the pair don their spacesuits, Pilot Jeff Ashby powers up theCanadarm 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 ISS, to a cradle on the Destiny module.ĮVA-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. EDT on Mission Day 4, Canadian Space Agency ( CSA) 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. Sunday April 22, 2001, is a historic day for Canada.
