Sounding rocket. Year: 1969. Family: Other Suborbital Vehicles. Country: Spain. Vehicle consisting of 4 x Chick + 1 x Goose. All motors ignited simultaneously at lift-off, the Chicks burning for 0.2 seconds, while the Goose continued for 17 seconds. The Instituto Nacional de Tecnica Aerospacial was tasked in 1967 to develop Spain's first sounding rocket. The requirement was to boost a 15 kg payload up to 150 km. INTA contracted with British Aerojet to provide the necessary technical expertise and designed a rocket built from existing solid motors. The technology acquired during the development and brief firing program led to the more ambitious INTA-300. Manufacturer: INTA. Launches: 3. First Launch Date: 1969-07-19. Last Launch Date: 1970-12-22. Launch data is: complete. Apogee: 150 km (90 mi). Liftoff Thrust: 42.000 kN (9,441 lbf). Total Mass: 340 kg (740 lb). Core Diameter: 0.26 m (0.85 ft).
