Immagine that Richard Nixon instead of JFK was elected President of United States in November 1960,and that Alan Shepard was the first man in space (but not in orbit) in Febraury 1961.
Two events that could happen.
In this scenario,if President Nixon not consider necessary a manned mission on the moon,how could take place the US space program in 1960s?
I have found that the original NASA program,before the moon decision,was Mercury missions until 1964,and orbital Apollo capsule from 1965 (with rendez vous,two week flights and EVA experiments as in the Gemini program).
From 1968 circa a Saturn 1B derived space station and a lunar flyby in 1970.
Is possible also a continuation of Dyna Soar X-20 as test spaceplane in order to acquire data for a some type of shuttle in 70s?
