I am really not sure how a "space program" would have saved the dinosaurs. It would not save humankind today to launch any sort of rocket or missile that we have on hand. The business of deflecting or disintegrating planet-killer asteroids is still the stuff of science-fiction and speculation. The reality of physics is that a sufficient mass with sufficient velocity is not something we would be able to send off-course (enough to make a difference) nor could we detonate it into little harmless splinters.
