How many manned moon landings have there been?

The story behind the answer

The correct answer is 6 because six Apollo missions successfully landed astronauts on the Moon: Apollo 11, 12, 14, 15, 16, and 17 (1969–1972). Apollo 13 did not land due to an in-flight emergency, though the crew returned safely. To date, only the United States has accomplished crewed lunar landings.

Context: These missions brought back about 382 kg (842 lb) of lunar rock and soil, deployed scientific experiments (ALSEP), and, on Apollo 15–17, used Lunar Rovers to explore farther from the landers. Memory tip: “11–12, skip 13, then 14–17” — that sequence adds up to six landings.
