MarkWhittington writes "One of the most vexing questions in the history of the space age is why have humans not gone to Mars yet. In 1969, when men first landed on the Moon, a follow on program to send people to Mars seemed all but inevitable.
A paper written by Robert D. Butts at Darmouth in 2003 suggests that there is a reason why no humans to Mars program happened in 1969, or has happened since. Succinctly put, while the political stars aligned in 1961 with a visionary president, Cold War fears of falling behind the Soviet Union, and a political consensus to use space as a peaceful battlefield to enhance American prestige that led to the Apollo landing program, quite a different alignment had occurred by 1969 to not only curtail Apollo but rule out any Mars program for the foreseeable future."
