The Proson-M1 was a two-stage meteorological sounding rocket developed by the Argentine Institute of Science and Technology for CITEFA in the 1960s, first launched on August 23, 1963, from CELPA (El Chamical). The rocket was launched using a delayed ignition system, with an 18-second interval between the first and second stages. Smoke charges were often used instead of payloads to study flight paths using optical tracking tools.
