First rocket to enter the exosphere

The Jupiter-C rocket marked a pivotal advancement in space exploration by becoming the first rocket to pass the thermopause and enter the exosphere. This achievement was significant as it demonstrated the capabilities of multi-stage rocket technology, which was essential for future space missions. The Jupiter-C reached an altitude of 682 miles (1,098 kilometers) and covered a range of 3,335 miles, setting new records for both height and distance traveled by a rocket at that time. The rocket achieved a velocity of MACH 18, showcasing the potential for high-speed travel beyond the Earth's atmosphere. This milestone not only contributed to the understanding of the upper layers of the atmosphere but also laid the groundwork for subsequent missions that would eventually lead to human spaceflight and exploration beyond Earth orbit. The success of the Jupiter-C was a result of extensive research and development in rocketry, reflecting the technological advancements of the era and the growing interest in space exploration by the United States.
