  • RETURN TO THE MOON: THIS TIME TO STAY Larry Taylor Dawn Taylor Planetary Geosciences InstituteDepartment of Earth & Planetary SciencesUniversity of Tennessee

  • July 20, 1969Dec. 12, 1972It is the Heritage of Mankind that We are Explorers,to Go Where No Person has Gone Before. In January, 2004, President Bushestablished a national program of returning humans to space, first to the Moon, then Mars, and beyond.

  • With Exploration and Settling of the Moon,We must Learn to Live Off the Land, in muchthe same way Our Ancestors Settled America.Water-Ice ??

    Living Conditions on the Moon No Atmosphere - Deep Vacuum : 10-12 to 10-15 atm

    Temperatures: Equator: Day = +125 0C; Night = -150 0C Avg. = -20 120 0C Poles: Dark = -220-240 0C Lighted = -50 20 0C Micrometeorite Impact : Velocities to >>105 km/hr

    Radiation: Galactic / Cosmic / Solar-ray Particles

  • Lunar Dust Effects: Must be Addressed before any Commercial Presence on the Moon can be Fully Evaluated. Potential for settling on all thermal and optical surfaces, such as Solar cells and mirrors; and Coatings, on seals, gaskets, optical lens, windows, electrical components, astronaut suits, etc.; and Abrasiveness, with regards to friction-bearing surfaces; Physiological effects on humans, especially with respect to the lungs, the lymph system, and potentially the cardiovascular system, in the case of extremely fine particles.SOLUTION: Magnetic brushes ??Lunar Dust Hay Fever, Jack Schmitt

  • ANOTHER WHITE HOUSE LEAK!!

  • MICROWAVE RADIATION for DUST MITIGATION There is an entire subculture of people who derive pleasure from putting strange things in microwave ovens Things that microwave oven manufacturers would strenuously suggest should not be put there. Table grapes produce glowing plasmas; Soap bars mutate into abominable soap monsters; Compact discs incandesce; Even Wet Poodles have been known to explode.
