In the near term, these rockets could make extensive surveys of the asteroid belt and outer solar system possible for light spacecraft. They would provide another strong incentive to build space-rated nuclear reactors. Finally, we could get beautiful images of the planets around the Alpha/Proxima Centari system - by flying a probe in the exact opposite direction.
This newly-discovered ice field is half-way between the north pole and the equator. It contains as much water as Lake Superior, and covers an area the size of New Mexico. It is between one and ten meters below the surface - very easy to reach by drilling or excavation by future Mars colonists.Continue Reading
