But did you know that every dollar spent on the space program returns seven dollars to the economy? The economy was very good during the years of the “space race” when we put men on the moon. the technology spin offs more than justify the costs of the programs. Then there is the science knowledge gained. And national pride. I watched Neil Armstrong on TV walking on the moon, and was reduced to tears. It was a great feeling. Mammograms were developed as a result of a need of the space programs, as well as micro computer circuits, velcro and literally thousands of other products.
