At Astrotech, Titusville, Fla., three workers watch as the overhead crane lifts and moves the ORU Transfer Device (OTD) to the top of the International Cargo Carrier (ICC). From left are Lora Laurence, with Johnson Space Center; Robert Wilkes, with Lockheed Martin; and Manfred Nordhoff, with Daimler-Chrysler Aerospace (DASA). The OTD is a U.S.-built crane that will be stowed on the International Space Station's Unity module for use during future ISS assembly missions. The nonpressurized ICC fits inside the payload bay of the orbiter. The ICC will also carry the SPACEHAB Oceaneering Space System Box (SHOSS), a logistics items carrier. SHOSS can hold a maximum of 400 pounds of equipment and will carry items to be used during STS-96 and future ISS assembly flights. The ICC will fly on mission STS-96, targeted for launch on May 20
