STS 100



STS 100 is an American shuttle spacecraft that was launched from Cape Canaveral at 18:41 UT on 19 April 2001 to dock with the International Space Station (ISS). It carried a crew of four Americans, one Russian, one Canadian and one Italian. The main mission was 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. It docked with the ISS at 13:59 UT on 21 April. The robotic arm was hooked to the ISS with the help of the shuttle's own 16 meter arm and two of the crew members. The seven-joint arm was not permanently bolted to the ISS, and will crawl along the exterior walls under computer control, temporarily anchoring wherever needed. There was a sequential failure of the three onboard computers on the ISS, but after four days of effort a backup computer was activated fairly enough to enable the Canadarm-2 to hand over its own packing crate to the shuttle arm. STS 100 undocked from the ISS on 29 April after retrieving Raffello, and landed at Edwards AFB in California on 01 May.
