Luna 24: the last lunar lander
The Soviet Union launches the robotic lunar lander and sample return mission, Luna 24. Touching down safely in the Mare Crisium region two weeks after its launch, Luna 24 drills a two-meter core sample of lunar soil for return to Earth in a small reentry capsule. Luna 24 is the final Soviet mission to the moon, and is the last vehicle from Earth to land on the moon in the 20th century. NASA and the Soviet space agency exchange samples of lunar soil later in 1976, since Luna 24 landed in a region unexplored by the Apollo manned landing missions.
