Beskrivning : Sich 1 was a Ukranian remote sensing satellite launched from the Plesetsk Cosmodrome by a Tsiklon-3 rocket. The spacecraft and instruments on board were similar to those of the Soviet Okean series. Its main mission was to monitor objects of several hundred meters in size, such as Arctic ice. A second payload, FASAT-Alpha, which was a Chilean spacecraft of 50 kg mass, could not be separated from Sich 1 and so had to be muted.
