Rocket Science is a Pretty Old Technology

The moon is a better place for space science than Earth. Little excuse exists for not establishing a permanent scientific base on the moon. A lazy, indolent nation would be slow to get off the ground on that project. The moon has clear skies, good viewing of the stars. Great solar power and super-conducting location and a fine defense base to protect the planet Earth against incoming threat-asteroids that could impact the Earth.

The moon is a good place to locate lasers and particle beam weapons to hit asteroids. It is a good location for a few good anti-asteroid missiles. Yet basic building science in very low temperature- lunar engineering technology need be established for practical development.

Lunar reflectivity should not be degraded. Buildings should reflect light at the same level as the  dirt (regolith) albedo. Scarce lunar ice should never be removed for any purpose including rockets. All existing ice should be recycled in greenhouses if used at all. Drinking and growing water are the sole justifiable uses for lunar ice. Spaceships builders need be a little more clever and not burn up the ice of the moon. The moon and all space planetary economics should be on a sustainable ecological foundation so humanity can start afresh at its importunate methods of using cheap environmental resources disposably instead of sustainably through good use of human intellectual skill.

Hydrogen and oxygen are often used to make rocket fuel. Those rocket scientists that want to exploit rare resources and ancient technology look at the lunar ice as fuel. Intelligent space-ship designers, alternatively, would use electro-magnetic mass drivers with solar power or plutonium power sources to get capsules off the moon. Ion engines could move vehicles in orbit to earth as well as numerous other power sources and propulsion types including lunar lasers hitting reactive surfaces on the aft of space ships returning to Earth.
