The Jupiter-C was a type of sounding rocket used for three sub-orbital spaceflights conducted in 1956 and 1957. It was designed by the Army Ballistic Missile Agency (ABMA), and all three flights were launched from the Cape Canaveral Air Force Station.
Each vehicle consisted of a modified Redstone ballistic missile with two solid-propellant upper stages. The tanks of the Redstone were lengthened by 8 ft (2.4 m) to provide additional propellant. Th...

The Jupiter-C was a type of sounding rocket used for three sub-orbital spaceflights conducted in 1956 and 1957. It was designed by the Army Ballistic Missile Agency (ABMA), and all three flights were launched from the Cape Canaveral Air Force Station.
Each vehicle consisted of a modified Redstone ballistic missile with two solid-propellant upper stages. The tanks of the Redstone were lengthened by 8 ft (2.4 m) to provide additional propellant. The instrument compartment was also smaller and lighter than the Redstone's. The second and third stages were clustered in a "tub" atop the vehicle. The second stage was an outer ring of eleven scaled-down Sergeant rocket engines; the third stage was a cluster of three scaled-down Sergeant rockets grouped within. These were held in position by bulkheads and rings and surrounded by a cylindrical outer shell. The webbed base plate of the shell rested on a ball bearing shaft mounted on the first-stage instrument section. Two electric motors spun in...
