The RL-10 was the world’s first operational liquid hydrogen/liquid oxygen high energy restartable 2nd stage rocket engine used in space.

Each individual engine produced 15,000 pounds of thrust. On January 29, 1964, a six-engine cluster of RL-10s generated 90,000 pounds of thrust to lift the first test flight of the Saturn S-IV stage, pioneering hydrogen technology on the Saturn I booster.

This particular RL-10 engine was launched from Cape Canaveral launch complex 36A on Sept. 30, 1977. Its mission was to deliver an Intelsat IV-A communications satellite to orbit.

The launched failed to a gas generator leak in the Atlas engine compartment, causing an explosion at 10,000 feet at T+30 seconds. The engine was recovered from the ocean and store by United Launch Alliance (ULA) before being donated to the museum in 2011.
