Space Shuttle OV-105 Endeavour was launched on mission STS-100 to carry out International Space Station Flight 6A continued the outfitting of the Station. The crew of four Americans, one Russian, one Canadian and one Italian were to install an 18 meter, 1,700 kg Canadian robotic arm named Canadarm-2 on the ISS, and to transport an Italian cargo container, Raffaello, which delivered 4,500 kg of supplies and equipment to the station. Total payload of 13,744 kg consisted of:

• Bay 1-2: Orbiter Docking System, External Airlock, 3 EMU spacesuits - 2160 kg including 360 kg for the 3 suits
• Bay 3 Starboard: Adapter Beam with DCSU switching unit - 180kg
• Bay 5: Spacelab Pallet with Canadarm-2 SSRMS (Space Station Remote Manipulator System, 1800 kg mass), LDA, and 56 kg UHF antenna - 3256 kg
• Bay 6 Port: Adapter Beam with IMAX Camera - 238 kg
• Bay 8-12: Rafaello Module (MPLM-2) with MPLM racks and 3400 kg cargo - 7500 kg
• Sill: Canadarm RMS 303 - 410 kg

Endeavour reached an 80 x 317 km orbit at 1849 GMT; at 1924 GMT the OMS engines fired to raise perigee. After a series of rendezvous burns, the spaceship docked with the PMA-2 port on the ISS at 1359 GMT on April 21.

On 23 April the SSRMS station manipulator was unberthed from the SLP Spacelab pallet at 1114 GMT and latched on to the PDGF fixture on the Destiny ISS module at 1416 GMT. This was followed at 1458 GMT with the MPLM-2 Raffaello module being moved from Endeavour's payload bay by the Shuttle's RMS and berthed to the nadir port on the ISS Unity module at 1600 GMT. Over the next few days, the cargo racks on the MPLM were transferred to Destiny. Raffaello was then unberthed from Unity at 2003 GMT on April 27 and reberthed in the rear of Endeavour's bay for return to earth at 2059 GMT.

Undocking of Endeavour was delayed by a series of computer problems at the Station. Failures in the Station's command and control computers left only one of the three computers operating.

They were all restarted by April 29, and the Shuttle RMS grappled the Spacelab pallet at 2044 GMT . The station's Canadarm-2 released it at 2106 GMT, and the RMS berthed the pallet back in the Shuttle cargo bay. Endeavour undocked from the Station at 1734 GMT on April 29. The weather in Florida was bad at the planned May 1 landing time, so Endeavour landed in California. The deorbit burn was at 1502 GMT on May 1, with landing at 1610:42 GMT on runway 22 at Edwards. Endeavour returned to the Kennedy Space Center atop a Boeing 747 SCA aircraft on May 9.
