Luna: New Moon, thoughts on earth to moon access.

Filed under: Uncategorized — foodnearsnellville @ 7:08 pm

This is a continuation of discussions begun here.

The fastest a probe has gone from Earth to Moon is a little less than nine hours, and when that probe passed the moon, it was traveling 36,000 miles an hour (circa 16,092 meters per second). That’s a pretty incredible delta V, considering, for example, that the muzzle velocity of a M14, hardly a slow poke of a weapon, is 850 meters per second. If military weapons can achieve those kinds of speeds, or perhaps more, with nuclear propulsion, then the delta V alone makes stone (or more likely, depleted uranium long rod penetrators) a potent weapon. Why depleted uranium? It’s cheap, a nuclear waste product, with a density approaching that of osmium.

The question we’re building to is: would our AWC (aggressive Western country) have a first strike lunar capability? In my mind, it could be done with missiles, but more intriguingly, it seems reasonable to ask if they have stealth space planes. In my mind, 100 years or more of development of this kind of vessel (starting dating from when Ronald Reagan proposed these ships) would not only realize this kind of craft but would also leave them modular in propulsion. The rocket-ramjet they lift with could be replaced with a nuclear motor (and water as fuel) once in orbit. My recollection is that nuclear motors have a higher specific impulse, and therefore, greater top end speed.

A lunar colony of the kind Luna:New Moon envisions has an excess of power. The D-He 3 fusion power plant has to be common, and many processes must rely on an abundance of power. Growth is limited by available biomass, and the element limiting growth most would be nitrogen. Oxygen, by contrast, is relatively common.

In the world of Luna, the Corta process is the nitrogen source, and yields other useful gasses (so again, if the Corta process is your nitrogen source, why are you bombing Corta processing plants? Are you really that much of a closed cycle vis a vis nitrogen?).

Food is a bottleneck, and growth of food is expensive in terms of energy, water, and light. But attacking food is a way to commit genocide in a lunar war, and really, something to be avoided.

Attacks should be specific. They should be directed at the lunar “instruments of war”. The lunar colony is just too vulnerable to handle indiscriminate attack. But to start answering the question originally proposed, our AWC could lift a squadron, say, of space vehicles over the span of a day, rearm them for interplanetary combat, and assuming a top speed in excess of 40,000 miles an hour, launch an attach in several hours. The first ships may carry no weapons at all, but rather, the optical equivalent of Britain’s Window.

Directed attacks: on Earth, cruise missiles work in part because those employing them have a terrain map of the Earth down to a very fine detail, and those maps are embedded in the targeting system of the weapons. Absolutely nothing prevents the use of the same kind of technology in a “smart weapon” attack on the moon.
