The main purpose of STS-105 was the rotation of the International Space Station crew and the delivery of supplies utilizing the Italian-built Multi Purpose Logistics Module (MPLM) Leonardo on its second flight (STS-102, STS-105). The crew also performed two spacewalks and conducted scientific experiments. The Multi Purpose Logistics Module (MLPM) taken on STS-105 contained additional scientific racks, equipment and supplies. It is 6.4 meters (21 feet) long and 4.6 meters (15 feet) in diameter and weighs over 4,082 kilograms (8,999 lb). An identical module named Raffaello has flown twice (STS-100 and, later, STS-108).
