Many Americans make the mistake of assuming that space research has no values here on earth. Nothing could be further from the truth. Just as the wartime development of radar gave us the transistor, and all that it made possible, so research in space medicine holds the promise of substantial benefit for those of us who are earthbound. For our effort in space is not as some have suggested, a competitor for the natural resources that we need to develop the earth. It is a working partner and a coproducer of these resources. And nothing makes this clearer than the fact that medicine in space is going to make our lives healthier and happier here on earth.
