Interesting scale model of the Centaur upper stage rocket designed to be carried aloft inside the Space Shuttle, measuring 12″ long and 8.5″ in diameter, set inside an acrylic display case and housed within its original wooden shipping crate, marked "NASA Exhibit Material," with the shipping address of the Glenn Research Center in Cleveland, Ohio. The model features the large LH2/LO2 tanks, avionics boxes, hydrazine and helium bottles, and dual main engines. In very good condition, with the two engine thrusters broken off from their mounting pegs, but retained by the attached tubing.
Two variants of the Shuttle-Centaur stage were developed, intended to be used to launch satellites into high Earth orbits or probes into deep space. The project was canceled following the Challenger disaster in 1986.
