The Space Shuttle Missions

The highest priority objectives of the flight were the installation, activation and checkout of the Canadarm2 robotic arm on the station. The arm - manufactured by MDA Space Missions under contract of the Canadian Space Agency and NASA, went into operation on 28 April 2001. It was critical to the capability to continue assembly of the International Space Station. The arm was also necessary to attach a new airlock to the station on the subsequent shuttle flight, mission STS-104. The final component of the Canadarm is the Mobile Base System (MBS), which was installed on board the station during the STS-111 flight.

Other major objectives for Endeavour's mission were to berth the Raffaello logistics module to the station, activate it, transfer cargo between Raffaello and the station, and reberth Raffaello in the shuttle's payload bay. Raffaello is the second of three Italian Space Agency-developed Multi-Purpose Logistics Module, manufactured out of stainless steel at the Cannes Mandelieu Space Center; that were launched to the station. The Leonardo module was launched and returned on the previous shuttle flight, STS-102, in March.

Remaining objectives included the transfer of other equipment to the station such as an Ultra-High Frequency communications antenna and a spare electronics component to be attached to the exterior during space walks. Finally, the transfer of supplies and water for use aboard the station, the transfer of experiments and experiment racks to the complex, and the transfer of items for return to Earth from the station to the shuttle were among the objectives.

Endeavour also boosted the station's altitude and performed a flyaround survey of the complex, including recording views of the station with an IMAX cargo bay camera.

All objectives were completed without incident, and reentry and landing happened uneventfully on 1 May 2001.

During this mission, astronaut Chris Hadfield made the first spacewalk by a Canadian.

EVA1 Parazynski and Hadfield deployed a UHF antenna on the Destiny lab. After that, the pair began installing the Canadarm2. Parazynski and Hadfield encountered a problem ensuring the proper torque was applied to the bolt. The pair switched the Pistol Grip Tool (PGT) to manual mode and attempted again successfully.
Hadfield experienced severe eye irritation during the spacewalk due to the anti-fog solution used to polish his spacesuit visor, temporarily blinding him and forcing him to vent oxygen into space. Other astronauts experienced a similar problem on subsequent spacewalks. Duration: 7hrs 10 min.
EVA2 Connected Power and Data Grapple Fixture (PDGF) circuits for the new arm on Destiny. Removed an early communications antenna and transferred a spare Direct Current Switching Unit (DCSU) from the shuttle's payload bay to an equipment storage rack on the outside of Destiny. Duration 7hrs 40min.
