Missions to the Moon have been numerous and represent some of the earliest endeavours in space missions, with continuous exploration of the Moon beginning in 1959.
The first partially successful lunar mission was Luna 1 in January 1959, which became the first probe to escape Earth's gravity and perform a flyby of another astronomical body, passing near the Moon. Soon after, the first Moon landing—and the first landing on any extraterrestrial body—was carried out by Luna 2, which intentionally impacted the Moon on 14 September 1959. The far side of the Moon, permanently hidden from Earth due to tidal locking, was imaged for the first time by Luna 3 on 7 October 1959, revealing terrain never before seen.
