After a problem with the spacecraft's propulsion system, instead of entering a low orbit around the Moon, it crashed into the lunar surface. The Russian mission to the Moon was one of several spacecraft that were to attempt a landing on the Moon in the next six months, alongside probes from Japan, India, and the United States.
