2013 Create the Future Design: Aerospace & Defense Category Winner

Microwave Extraction of Water for Space Propellant Edwin Ethridge, Ph.D. NASA (retired), Huntsville, ALSpace exploration is extremely expensive because very large rockets are required to put small payloads into space. Large reductions in launch mass will come from production of inspace rocket propellant from in-space water. Vast quantities of water are present at the lunar poles, on Mars, comets, and some asteroids. Using the in-space resource of solar energy, in-space water can be split into hydrogen and oxygen for propellant. Molecular water can even be used for the reaction mass ejecta with ion engines for missions to Mars and beyond.
