Russian earth magnetosphere satellite. In July 1956 OKB-1 completed the draft project for the first earth satellite, designated ISZ (Artificial Earth Satellite). Scientific satellite, Russia. Launched 1958.

AKA: D-1;ISZ. Status: Operational 1958. First Launch: 1958-04-27. Last Launch: 1958-05-15. Number: 2 . Gross mass: 1,327 kg (2,925 lb).

The government go-ahead came in a decree of 3 September 1956. The Fourth Scientific Research Institute of the Ministry of Defense had meanwhile completed a draft project for the KIK ground control system. Tikhonravov's 1.4 metric ton ISZ satellite was to have been launched by the new R-7 ICBM as the Soviet Union's first satellite, but the R-7 was ready before the satellite, so it was preceded by Sputnik 1 and Sputnik 2. The ISZ was a miniature physics laboratory, but was launched with a known faulty recorder, limiting data to that received when the spacecraft was over Soviet tracking stations. As a result, the Van Allen radiation belts were discovered by the United States rather than Russia.
