The Moon BackwardsPeter A. Garretson
America will return to the Moon as early as 2015 and no later than 2020 and use it for a stepping stone for more ambitious missions. A series of robotic missions to the Moon...will explore the lunar surface beginning no later than 2008 to research and prepare for future human exploration. Using the Crew Exploration Vehicle, humans will conduct extended lunar missions as early as 2015, with the goal of living and working there for increasingly extended periods." --President Bush Statement on New Space InitiativeOur leadership says we will be there.
2003 saw launch to and return from Space of the first astronaut by China. China's GNP now exceeds where we were when we began the Apollo Program.
If reports of a manned landing by 2010 are exaggerated, Ouyang Ziyuan was willing to say that he could foresee manned outposts on the Moon in the long-term, "perhaps by 2020 or 2030". The Moon could serve as a new and tremendous supplier of energy and resources for human beings," he said. "This is crucial to sustainable development of human beings on Earth." "Whoever first conquers the Moon will benefit first," Mr Ouyang added. "As for China, it needs to adopt a strategy based on its concrete economic power and technology level. "We are also looking further out into the Solar System - to Mars." --Ouyang Ziyuan, chief scientist of China's Moon exploration programmeThe Dragon in SpaceCompetition!
Competition!"We are planning to build a permanent base on the moon by 2015 and by 2020 we can begin the industrial-scale delivery ... of the rare isotope Helium-3," Nikolai Sevastyanov, head of the Energia space corporation, was quoted by ITAR-TASS news agency as saying at an academic conference.
Location: The moon is closeJust 60-70 hours away (3 days)238,712 mi (384,400 km)
Location:The moon is a strategic position, everyone must pass by it to go anywhere elseLOC Control: The equivalent of the Rock of Gibraltar
Location:The moon is a fueling station and safe harbor, not unlike Hawaii in the age of coal
Location:The moon is a stable platform from which to view the earth and stars
Land:More surface area than all of AfricaSurface Area - 14,657,449 mi sq. (37,958,621 km sq.) 9.4 billion acres
Resources:The moon is rich, and you dont have to carry its wealth up the gravity well
Resources: Rare Earths
Energy Security:The moon has virtually unlimited He3 About 1 million tons of helium 3 on the moon, enough to power the world for thousands of yearsHe3 costs about $6B/ton on earth He3 can be burned for propulsion now
Energy Security:The moon has virtually unlimited materials for Solar Power Station Construction
It takes less energy, and is technically less complex (no atmosphere or aerodynamics) to get materials from the Moon to LEO than to get the materials from the Earth to LEO.There are adequate materials on the Moon (aluminum, titanium, iron, oxygen, silicon) to construct many objects of interest (Rocket Motors, Fuel Tanks, Shelters, etc.)
22 times less energy!1/6th Earths Gravity (0.1622 gee) butIt takes more than 21.7 times the energy to get the same payload off the Earth!lunar escape velocity of 2.4 km/s Earth Escape velocity 11.2 km/sA Lot Less Propellant!A Lot Higher Payload Mass Fraction!And no Air Resistance or DragAllows expansion of CIS-Lunar Mass by 1 to 2 orders of magnitude
A Logos Study said:Payload Mass Fraction Earth to LEO: 1.5%Payload Mass Fraction, Lunar Surface to Low Lunar Orbit (LLO): 50% Escape: 35%To put 2,400 tons into CIS-Lunar space (L2) would take:35 launches in the first 5 years (Titan IVB) to put 3T on the Moon, or 810 launches over 15 years
Dennis Wingo Says3 Billion Metric Tons of impact metal having 62 million Kilos of Platinum Group MetalsA Single Diablo Canyon size impactor would have left between 450 million to 1.77 billion tons of economically recoverable nickel/iron/cobalt/PGM material, worth around $20 Trillion
But Lee Morin says:$100,000/lbanything you can make from lunar materials has an intrinsic value add of $100,000/lb We can only get 10% of the mass we can get to LEO to the Lunar Surface (one way)Surveyor was 408 kg or 900 lbsApollo was 6,900 kg or 15,211 lbsActual Deliverable with COTS: 1000 kgCompound Interest: If a 1000 kg seed can replicate 114 grams an hour, it doubles every year
Wouldnt it be nice?How nice it would be if the first new visitors to the Moon could be picked up in Earth orbit, and be taken to a fully outfitted base. Would it not be nice if the first guests to the Moon could be paying guests as they are on the first flight of an Airliner? How could we make this happen?
Here is the basic idea:Dont lift fuel and spaceships from the Earth to get to the Moon in order to then build a colony there. Rather, build the colony and space-ships on the Moon where the gravity well is small, and send the fuel and spaceships.

A lesson from natureSpecialization
Screen ManufacturingExtrude Screen to make multiple objectsFoil, or inflatables may also be appropriate
Sheet Metal WorkingSimple, well-known techniquesCreate a variety of complex shapes
Vapor Deposition ProcessSuccessive deposition of layers (Iron, Titanium, Silicon) over mesh to create Solid Complex shapes, structural members, ICs and pressure volumes
Phase 1: Send the TeamOne Queen and two Diggers
Phase 2: Digger ReplicationDiggers bring the raw materials to the queen, which the queen processes
Phase 3: Colony Split
Phase 4: Base ConstructionCreate Pressure VesselsFill them with Lunar Oxygen
Phase 4: Base ConstructionPave Landing ZonesPave Solar CellsBurry Pressure Vessels
Phase 5: Spaceship ConstructionEven rocket engines can be madeLaunch is simplified:No Atmosphere; no ShroudsNo volume, aero constraints
Phase 6: Ferry to Lunar OrbitLaunch both pressure vessels and propellantUse precious metals (PGMs) as the pressure vessels
Phase 7: Ferry to Earth OrbitRoomy vessels only need to be furnishedArrive in LEO ready for pick-upPeople only need to get to LEO
Phase 8: Stable OpsFirst visitors arrive to a spacious facility

Solar Power Satellites"because of large scale operation of the system, delivered power costs are predicted to be competitive with coal or nuclear power plants. For example, if a $12.5 billion ($2,500 per kilowatt in 1981 dollars) system capable of 5,000 megawatt output were purchased, it might cost around $78 billion over 40 years to own and operate it ($12 billion in depreciation plus $21 billion interest at 12 percent, $33 billion earnings at 18 percent, plus $12 billion in operating expenses, taxes, and other costs). The station would deliver. Hence, the average cost of the power delivered is under five cents per kilowatt hour. A comprehensive assessment of a 1.6 trillion kilowatt hours of power over 40 years representative space based energy system was conducted by the Department of Energy from 1977 to 1981. Their evaluation did not reveal any technological barriers....Finally, demonstration of cost attainability for key system elements would be required prior to seeking funds for full scale implementation.
