Sputnik 25 was an attempted Soviet lunar soft landing intended to return data on the mechanical characteristics of the lunar surface, the hazards presented by the topology, and radiation, in preparation for future manned landings. The spacecraft was injected into Earth orbit successfully but failed to escape orbit for its trip to the Moon, and its orbit decayed on 5 January 1963.
