The Jupiter C was an early American sounding rocket developed in the 1950s. It was designed to gather data from the upper atmosphere and was part of the broader efforts of the United States during the Cold War to advance its space technology. The rocket was launched from the Cape Canaveral Air Force Station and was notable for its use of a modified version of the Jupiter missile. The first successful launch of the Jupiter C occurred on January 31, 1956. It reached an altitude of about 1,000 kilometers, demonstrating the potential for future space exploration. The data collected from these missions contributed to the development of more advanced rockets and satellite technology, paving the way for the space race that followed.
