At SPACEHAB, Cape Canaveral, Fla., members of the STS-107 crew look over experiments for their mission. Pilot William "Willie" McCool (left) displays a glove box experiment for the trainers (right). STS-107 has two payload elements, the Double Module in its first flight into space and a Hitchhiker payload. The experiments range from material sciences to life sciences (many rats). The Hitchhiker carrier system is modular and expandable in accordance with payload requirements. Hitchhiker experiments are housed in canisters or attached to mounting plates. The Hitchhiker canister comes in two varieties--the Hitchhiker Motorized Door Canister and the Sealed Canisters. STS-107 is scheduled to launch in June 2002
