ISS Elements: Spacehab Integrated Cargo Carrier
Source: Shuttle Press Kit
The Spacehab Integrated Cargo Carrier is used to accommodate and support the transfer of exterior cargo from the shuttle orbiter to the International Space Station and from the station to work sites on the truss assemblies.
ICC configuration for STS-101
The ICC provides sufficient surface area in the orbiter cargo bay to carry approximately 8,000 pounds of cargo, which would otherwise have to be carried in the shuttle's cabin.
The ICC is an unpressurized flatbed pallet and keel yoke assembly housed in the orbiter's payload bay. Constructed of aluminum, it is 8 feet long, 15 feet wide and 10 inches thick, and is capable of carrying cargo on both faces of the pallet, both on top and below. There are no active interfaces (thermal, electrical or data) to the shuttle.
On Mission STS-101, the ICC carried three cargoes: parts of the Russian Strela crane, the Space Integrated Global Positioning System/Inertial Navigation System (SIGI) Orbital Attitude Readiness (SOAR) payload, and the Spacehab -Oceaneering Space System (SHOSS) box.
