Here's a breakdown:
* Apollo 11 (1969): The first successful moon landing, with Neil Armstrong and Buzz Aldrin becoming the first humans to walk on the moon.
* Apollo 12 (1969): The second lunar landing, focusing on scientific experiments and surveying the moon.
* Apollo 14 (1971): Focused on lunar geology and collecting samples.
* Apollo 15 (1971): The first mission to use a lunar rover, allowing for wider exploration.
* Apollo 16 (1972): Focused on lunar geology and collecting samples.
* Apollo 17 (1972): The last crewed mission to the moon, again focusing on lunar geology and collecting samples.
While there were other missions related to the moon, like the Apollo 10 mission which orbited the moon but didn't land, those six missions mark the only times humans have set foot on the lunar surface.
