Launch of Space Shuttle Discovery during STS-105. August 10, 2001.
The primary purpose of STS-105 was the rotation of International Space Station Crew, bringing Expedition 3 to the orbiting laboratory and returning the Expedition 2 crew, and the delivery of 6,775 pounds of scientific racks, equipment, and supplies using the Italian-built Multi Purpose Logistics Module Leonardo.

Additional payload included Materials International Space Station Experiments (MISSE) Passive Experiment Containers (PEC) 1 and 2. MISSE investigated the long-term exposure of materials to the space environment. MISSE PECs 1 and 2 included 910 specimens of various materials to be tested outside of the International Space Station. PECs 1 and 2 were later recovered by STS-114 in 2005.
One of the MISSE PECs installed on the outside of the Quest airlock.
Two spacewalks were performed during STS-105 by Mission Specialists Patrick Forrester and Daniel Barry. The first EVA on August 16 was performed to install the Early Ammonia Servicer, which would supply ammonia to the International Space Station's cooling system if needed. EVA 1 lasted 6 hours and 16 minutes. The second EVA on August 18 prepared the space station for the delivery of the S0 truss by STS-110 in 2002. EVA 2 lasted 5 hours and 29 minutes.
