The Moon Backwards
  • Peter A. Garretson

Our leadership says we will be there.
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
Initiative

Competition!
The Dragon in Space
  • 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 programme

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.

6
Location The moon is close
Just 60-70 hours away (3 days) 238,712 mi
(384,400 km)
7
Location
8
Location
  • The moon is a strategic position, everyone must
    pass by it to go anywhere else

LOC Control The equivalent of the Rock of
Gibraltar
9
Location
  • The moon is a fueling station and safe harbor,
    not unlike Hawaii in the age of coal

10
Location
  • The moon is a stable platform from which to view
    the earth and stars

11
Land
  • More surface area than all of Africa

Surface Area - 14,657,449 mi sq. (37,958,621 km
sq.) 9.4 billion acres
12
Resources
  • The moon is rich, and you dont have to carry its
    wealth up the gravity well

13
Resources Iron
14
Resources Titanium
15
Resources Rare Earths
16
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 years
  • He3 costs about 6B/ton on earth
  • He3 can be burned for propulsion now

17
Energy Security
  • The moon has virtually unlimited materials for
    Solar Power Station Construction

18
Facts
  • 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.)

19
22 times less energy!
  • 1/6th Earths Gravity (0.1622 gee) but
  • It 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/s
  • A Lot Less Propellant!
  • A Lot Higher Payload Mass Fraction!
  • And no Air Resistance or Drag
  • Allows expansion of CIS-Lunar Mass by 1 to 2
    orders of magnitude

20
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

21
Dennis Wingo Says
  • 3 Billion Metric Tons of impact metal having 62
    million Kilos of Platinum Group Metals
  • A 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

22
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 lbs
  • Apollo was 6,900 kg or 15,211 lbs
  • Actual Deliverable with COTS 1000 kg
  • Compound Interest If a 1000 kg seed can
    replicate 114 grams an hour, it doubles every year

23
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?

24
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.

25
Queens and Workers
  • Workers feed Queen
  • Queen makes Workers (Diggers)

A lesson from nature
  • Specialization

29
Screen Manufacturing
  • Extrude Screen to make multiple objects
  • Foil, or inflatables may also be appropriate

30
Sheet Metal Working

31
Vapor Deposition Process
  • Successive deposition of layers (Iron, Titanium,
    Silicon) over mesh to create
  • Solid Complex shapes, structural members, ICs
    and pressure volumes

32

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.
