how many apollo missions were there

There were 17 Apollo missions officially numbered Apollo 1 through Apollo 17, though not all of them went to the moon and some were uncrewed test flights.

Quick Scoop

• The Apollo program ran from the early 1960s to 1972 and used mission numbers Apollo 1, then Apollo 4–17 (there was no Apollo 2 or 3).

• Apollo 4, 5, and 6 were uncrewed test flights of the Saturn rocket and spacecraft systems.

• Crewed lunar missions began with Apollo 7; in total, 11 crewed Apollo missions flew (Apollo 7–17, with Apollo 13 not landing on the Moon).

• Six missions actually landed humans on the Moon: Apollo 11, 12, 14, 15, 16, and 17.

So, if you’re asking “how many Apollo missions were there” in the broad program sense, the usual answer is 17 numbered Apollo missions (1, 4–17), of which 11 were crewed and 6 achieved lunar landings.

Over time, people online still debate this, often mixing up “total Apollo missions,” “crewed Apollo missions,” and “Moon-landing missions,” which keeps the topic popping up in space-history forums as a small but recurring trending question.

TL;DR:

• 17 Apollo missions in the program (numbered 1, 4–17).
• 11 crewed Apollo missions.
• 6 Moon landings.
