Koan, time shows up pretty much everywhere in Newtonian physics (x = vt for example). If you want to argue that QM was needed to get into space, I'd simply point out that electronics were needed for the control systems, and they of course are based on QM. Its likely possible to orbit a rocket sans electronics (mechanical gyros for control) although the orbital params would likely not be super accurate, but I suspect it would be much harder to get survivable reentry for humans sans electronics.

en.wikipedia.org read up! "Newton's law has since been superseded by Einstein's theory of general relativity, but it continues to be used as an excellent approximation of the effects of gravity. Relativity is only required when there is a need for extreme precision, or when dealing with gravitation for extremely massive and dense objects." "Quantum mechanics (QM), also known as quantum physics or quantum theory, is a branch of physics that provides a mathematical description of much of the particle-like and wave-like behavior and interactions of energy and matter departing from classical mechanics at the atomic and subatomic scales" As far as I know moon and other planets are bit larger than atoms! As always you have your way with words and it seems like you have a lot of time on your hands to spew misinformation. As a homework, show me quantum equation for force required to move 1kg of mass from earth to mars, since you so strongly believe that is what is required.
