== Background == Following the launch of the Soviet [[Sputnik 1]] on 4 October 1957, the Army Ballistic Missile Agency (ABMA) was directed to proceed with the launching of a satellite using the Juno I four-stage variant of the three-stage [[Jupiter-C]], which had already been flight-tested in nose-cone re-entry tests for the [[PGM-19 Jupiter|Jupiter IRBM]] ([[intermediate-range ballistic missile]]). Working closely together, ABMA and [[Jet Propulsion Laboratory]] (JPL) completed the job of modifying the Jupiter-C and building Explorer 1 in 84 days.
