Mission details:

• The Cosmos-1870 large oceanographic satellite was deorbited by the Soviets on Jul 29, 1989 almost exactly two years after its launch. The automated satellite was launched by a Proton and was probably a Salyut class vehicle. Relatively little information about its payload has been released, suggesting that its mission may have been partly military in nature.
