In 1955 Convair won the prime contract for Atlas ICBM.The liquid oxygen and kerosene vehicle was designed to carry a thermonuclear warhead over 7000 miles. The Atlas was unique in its “stage and half” design in which two of its main engines were shed to reduce weight after two minutes of flight, while the central sustainer continued to burn. In order to minimize sustainer tank weight (used also for booster engines), Convair employeed balloon construction. Flights of Atlas began on June 11, 1957, with the launch of Atlas A powered by booster alone. In November 1958, an Atlas B reached full design range, and the operational Atlas D was deployed in 1960.
Atlas Able was based on combination of Atlas booster and upper stages from a Vanguard launch vehicle (second stage was liquid fueled AJ 10, topped by the X248 solid fueled third stage). The goal was to send Pioneer probe into lunar orbit. Pioneer probe was a small sphere with four solar panels. A small injection rocket on top of the probe would slow it into lunar orbit. 3 Atlas Ables were launched with no success. Pioneer P-31 was launched on December 15th, 1960. All worked well until T+68 seconds into the flight when the second stage ignited three minutes early, while still atttached to the Atlas. This resulted in a fireball that destroyed the entire vehicle.
