Earth’s moon is the perfect launch point for the journey to Mars and other deep space missions, argues inventor William D. Eatwell. By returning to the moon, America and its closest and trusted allies can ensure their nations’ safety and that of all orbiting assets circling both the Earth and the moon. WE MUST RETURN details the possible international dangers and consequences of not going back. The urgent reasons to return are discussed in several chapters, which outlines critical issues regarding practical, tactical and strategic, protection and survival, and mining opportunities. Eatwell, a 25 year member of the AIAA, is privately developing advanced aerospace concepts. In this book, he reasons that America’s return to the lunar surface is critical to solving the enormous technical challenges that lie ahead on the journey to Mars.
