Jupiter-C launched America's first satellite, Explorer 1, on January
31, 1958. Designed by the von Braun team and built by the Army,
the Jupiter-C was a modified Redstone ballistic missile with three
added stages. Its liquid-propellant main-stage engine derived from
the Navaho missile program. The upper stages used solid propellants.
Jupiter-C displayed in the Museum is a full-scale model with a replica
of Explorer 1 on top.
