Integrated cargo carrier
The ICC carriers flew on 12 Space Shuttle missions between 1999 and 2010 under NASA's Cargo Mission Contract contributing to the construction, supply and maintenance of the International Space Station (ISS), transporting more than 50 unpressurized cargo elements (over 34,000 pounds) into orbit and providing for permanent attachment of two External Stowage Platforms (ESP-2 and ESP-3) to the ISS.Four types of ICC carriers have flown into orbit aboard the Space Shuttle: The ICC-G is a horizontal cross-bay carrier consisting primarily of two components: The UCP is the primary structural element of the ICC that provides structural support for payload items carried in the unpressurized volume of the Orbiter’s cargo bay.The ICC-L is the principal one half of an ICC-G, using the removable core section from the not-flown ICC-V (Vertical) rotated into a horizontal orientation and combining it with the KYA.While grappled to the Space Station's robotic arm, the ICC-VLD's cargo elements, called Orbital Replacement Units ORUs were transferred with Extra-vehicular activity (EVA) assistance to the respective locations on the ISS.The ICC-VLD provided heater power and electrical connections for the ORUs while inside the cargo bay or grappled by the robotic arm.
