Aerobee X-8

Mission Profile

The Aerobee X-8 was an early American two-stage sounding rocket and one of the first variants in the prolific Aerobee family, developed in the late 1940s for high-altitude atmospheric and cosmic ray research. Standing just 6 m tall with a 0.4 m diameter and a liftoff mass of 750 kg, it generated 12 kN of thrust — modest but sufficient for the early upper atmosphere studies it was designed to conduct. First flown in December 1949, the Aerobee X-8 established the foundational research platform that would grow into decades of scientific sounding rocket launches across the United States.
