On Feb. 3, 1966, the Russians succeeded in landing the Luna 9 unmanned spacecraft gently on the moon's surface. Three months later, U.S. unmanned spacecraft Surveyor 1 also landed safely. Before these, all spacecraft sent to the moon had crash landed, some before they had managed to send back any data to Earth.
