From 1969 to 1972, there were six manned landings on the moon. Apollos 11, 12, 14, 15, 16 and 17 all landed safely on the moon's surface and returned to Earth, allowing 12 astronauts to set foot on Earth's satellite.
In addition to the six manned landings, as of 2014, there have been 10 missions that successfully landed unmanned probes or rovers on the moon. The most recent landing on the moon was the Chang'e 3 mission, launched by China. On December 14, 2013, the probe landed and deployed the Yutu rover.
There have also been six successful impactor missions to the moon, utilizing spacecraft designed to crash into its surface to collect scientific data.
