The Apollo Missions
There were 22 unmanned Apollo missions, some testing the Saturn V & Saturn 1B launchers, others testing the Apollo rocket with the launcher. These included Apollos 1-6.
Apollo AS-204 was a crewed non-flight test of the Apollo, resulting in the deaths of the crew by fire, and retrospectively named Apollo 1 in their memory.
Apollos 7 and 9 were in Earth orbit.
