Despite the recent buzz about eventually mining asteroids for metals, their real near-term value may be as space-based sources of water and carbon dioxide from which to make rocket propellant.
LIVERMORE -- Disaster movies from "Deep Impact" to "Asteroid" to "Armageddon" have mined drama from the mortal threat humanity could face if a massive asteroid were speeding towards Earth. At Lawrence Livermore National Laboratory, scientists are ...
