Integrated Cargo Carrier

Integrated Cargo Carrier (ICC) was a project, started in 1997 by the companies Spacehab and Astrium North America, Inc., to develop a family of flight proven and certified cross-the-bay cargo carriers designed to fly inside the Space Shuttle cargo bay, installed either horizontally or vertically, and able to carry up to 8000 lbs. of unpressurized cargo into orbit. Astrium North America, Inc. currently owns the ICC fleet of carriers. 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. Astrium North America's former Cape Canaveral integration facility, which was located at Astrotech's processing facility (formerly SPACEHAB Payload Processing Facility (SPPF)) provided for the physical integration of cargoes to the ICC and subsequent transport to Kennedy Space Center for orbiter installation. Due to its modular design and versatility, options to adapt the ICC design to new commercial orbital space transportation vehicles exist.

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-G UCP's dimensions are approx. 14 feet (width) × 8.5 feet (length) × 10 inches (thick). Cargoes can be mounted on both faces of the UCP. The KYA is a U-shaped structure whose primary purpose is to transfer UCP loads to the Orbiter via longeron and keel trunnions. The KYA’s design allowed it to be installed under pressurized tunnel sections in the Orbiter payload bay, thereby allowing the ICC-G to be used in conjunction with a SPACEHAB pressurized module. The ICC-G flew on seven Space Shuttle missions: STS-96/2A.1, STS-101/2A.2a, STS-106/2A.2b, STS-102/5A.1, STS-105/7A.1, STS-121/ULF1.1 and STS-116/12A.1.
