Eisenhower administration
Space programs such as the Explorer satellite were proposed by the Army Ballistic Missile Agency (ABMA), but Eisenhower, seeking to avoid giving the US space program the militaristic image Americans had of the Soviet program, had rejected Explorer in favor of the Vanguard, but after numerous embarrassing Vanguard failures, was forced to give the go-ahead to the Army's launch.
