If you have any anti-science types in your circle and they start yattering about sending ‘all that money to Mars’ remind them of the fact a crushed car bale—is around $250 a ton if it were pure steel. With plastics, not so much. That’s ALL we ever send off the Earth. The money stays on earth, buying hamburgers and paying housepayments for American workers, while the new processes and materials we produce along the way create new jobs and save lives. NASA returns a dollar for every dime we spend. So it costs us NOTHING to send stuff into space. It actually pays us. Being at it constantly with the research and the testing—is good for our economy. It’s creating something out of pure thought—a lot like writing books, until you get to the printing part. And that’s the most economical creative process there is.
