POSTAR

When the Space Shuttle Endeavour went up into space for the STS-47
mission, it carried the first Boy Scouts of America Exploring Division
experiments. The experiments were in the "Get Away Special" (GAS) G-102
canister mounted on the GAS bridge in the shuttle bay with
Spacelab J.

GAS G-102 is known as "Project POSTAR" to the Explorers and stands for
"post" and "star." POSTAR started in late 1978 when the Exploring Division
of the BSA announced the opportunity for Explorer posts to design
experiments to fly on the space shuttle. Exploring is the young adult,
co-educational divison of the BSA.
