The Centauro series is a family of Argentinian solid-fuel sounding rockets developed by the Instituto de Investigaciones Aeronauticas y Espaciales (IIAE). This family includes Alfa, Beta, and Gamma Centauro.[1][2][3]
Alfa Centauro was a single-stage rocket, launched in 1961 from Santo Tomás base.
Beta Centauro followed the same year, demonstrating two-stage capability and leading to advancements in payload delivery and high altitude measurements. Further launches from Santo Tomás and CELPA Chamical refined rocketry techniques. Notably, the "sodium cloud" operation in 1963 provided valuable atmospheric data.
The Gamma Centauro, also a two-stage vehicle, was tested after 1964, notably from Antarctica.[4]
