The spacecraft was intended for launch on an Atlas C-Able rocket, but this vehicle was destroyed on 24 September 1959 in an explosion on its launch pad during a pre-launch static firing. The P-1 spacecraft and an Able IV space engine were not present on the launch vehicle when it exploded, and were later used on the Pioneer P-3 mission.[1][2]
