Hvor mange apollo-missioner skulle der være?

Canceled Apollo missions
Flere planlagte missioner i Apollo-programmet for bemandet månelanding i 1960'erne og 1970'erne blev aflyst af forskellige årsager, herunder ændringer i den tekniske retning, Apollo 1-branden, forsinkelser i hardwaren og budgetbegrænsninger. Efter landingen med Apollo 12 blev Apollo 20, som skulle have været den sidste bemandede mission til Månen, aflyst for at give Skylab mulighed for at blive opsendt som et "tørt værksted" (samlet på jorden). De næste to missioner, Apollos 18 og 19, blev senere aflyst efter Apollo 13-hændelsen og yderligere budgetnedskæringer. To Skylab-missioner endte også med at blive aflyst. To komplette Saturn V'er endte med at blive ubrugt og er i øjeblikket udstillet flere steder rundt om i USA.

Canceled Apollo missions
Several planned missions of the Apollo manned Moon landing program of the 1960s and 1970s were canceled for a variety of reasons, including changes in technical direction, the Apollo 1 fire, hardware delays, and budget limitations. After the landing by Apollo 12, Apollo 20, which would have been the final manned mission to the Moon, was canceled to allow Skylab to launch as a "dry workshop" (assembled on the ground). The next two missions, Apollos 18 and 19, were later canceled after the Apollo 13 incident and further budget cuts. Two Skylab missions also ended up being canceled. Two complete Saturn Vs ended up going unused and are currently on display in multiple locations around the United States.
