VERY RARE, LARGE-SCALE CUSTOM BUILT MODEL OF THE CANCELLED CENTAUR-G ROCKET STAGE. The Centaur-G Prime liquid-fueled upper rocket stage was built in the 1980s to boost shuttle payloads out of low Earth orbit. It was originally scheduled to fly in 1986, but was cancelled after the Challenger disaster due to concerns that a cyrogenic liquid-fueled stage would be too risky to launch on the space shuttle.
