The M-100 was a two-stage Soviet sounding rocket. As some 6640 of these rockets were built between 1957 and 1990, it was the most used sounding rocket model ever. Payloads typically radioed science data to ground while descending by parachute. Cross-calibrations with Western counterparts has allowed data's inclusion in global databases. Unfortunately, production ceased on demise of Soviet Union.
M-100 rockets were not only launched from sites in the former Soviet Union. Launches also took place from Kerguelen island, Koroni in Greece and Akita in Japan.
