"Today when knowledge grows at an ever-increasing rate, we are becoming acutely aware of man's influence, as well as his dependence, on his environment. Problems of pollution and depletion of resources arise from man's use and misuse of his environment. Knowledge and use of understanding, as well as technological capability and social determination, will be required to solve these global difficulties. ..The Moon and planets collectively hold the key to that full understanding of planetary original and evolution that we will need in order to solve most effectively our challenges on Earth. Through study of both their similarities to and differences from Earth, the planets will provide greater insight into the mysteries of our own planet."
