Rocket Engine, Liquid Fuel, Redstone Missile
This is the Redstone missile engine. Developed from 1950, it served as the powerplant for the Redstone missile, this country's first large-scale operational liquid propellant missile. On 31 January 1958, a modified version of the engine propelled the Jupiter-C launch vehicle that orbited the U.S.'s first artificial satellite, Explorer 1. The engine also launched the first American into space, Alan B. Shepard, aboard the Mercury-Redstone 3 (MR-3) on 5 May 1961.
In the Redstone missile the engine had a thrust of 78,000 pounds and used liquid oxygen and alcohol. As a booster for MR-3, it used Hydyne propellant, a hydrazine derivative, and produced 83,000 lbs of thrust.
