"The Shuttle can't go to the Moon"

I think that hydrogen is scarce on the moon. The Clementine probe detected some in the deep craters at the South Pole and this has often been extrapolated to mean that these craters contain water ice since water has a high concentration of hydrogen. <br /><br />However I don't think that hydrogen has been found anywhere else in significant quantities. The luna crust has about 50 parts per million of hydrogen and thats it. More from wikipedia.<br />

I checked into that Clementine probe, and they could do a better job at reporting their findings in my opinion.<br /><br />Anyway, isn't there something else entering the Moon's orbit currently? Something from the UK?<br /><br />--- http:// jatslo.com/ : Jatslo

<i><br /><br />ESA's SMART-1 captured its first close-range images of the Moon this January, during a sequence of test lunar observations from an altitude between 1000 and 5000 kilometres above the lunar surface.<br /><br />--- http://www.esa.int/export/SPECIALS/SMART-1/SEM6S2XJD1E_0_ov.html<br /><br /></i>

Hydrogen peroxide often decomposes exothermically into water and oxygen gas spontaneously:<br /><br />2H2O2 - /> 2H2O + O2 + Energy<br /><br />The rate of decomposition is dependent on the temperature and concentration of the peroxide, as well as the presence of impurities and stabilizers. The ability of peroxide to coexist with a substance is called compatibility. Peroxide is incompatible with many substances, including most of the transition metals (i.e. iron, copper, silver, cobalt, etc.) and their compounds, many organic compounds, dirt, human beings, etc. these things are catalase or carry Catalyze. Spilling high concentration peroxide on a flammable substance can cause an immediate fire fueled by the oxygen released by the decomposing Hydrogen Peroxide.<br /><br />I have found no reference to Hydrogen Peroxide happening naturally; however, it would seem more likely that the sources of Hydrogen on the Earth's Moon derive from water ice.<br /><br />--- http://jatslo.com/ : Jatslo<br />

<i>The Lunar Prospector, a NASA Discovery mission, was launched into lunar orbit in January 1998. Included on Lunar Prospector is an experiment called the Neutron Spectrometer. This experiment is designed to detect minute amounts of water ice at a level of less than 0.01%. The instrument concentrated on areas near the lunar poles where it was thought these water ice deposits might be found. The Neutron Spectrometer looks for so-called "slow" (or thermal) and "intermediate" (or epithermal) neutrons which result from collisions of normal "fast" neutrons with hydrogen atoms. A significant amount of hydrogen would indicate the existence of water. The data show a distinctive 4.6 percent signature over the north polar region and a 3.0 percent signature over the south, a strong indication that water is present in both these areas. The instrument can detect water to a depth of about half a meter.</i><br /><br />--- http://nssdc.gsfc.nasa.gov/planetary/ice/ice_moon.html<br /><br />Would it be possible that water ice exists deeper than 1 meter below the surface of the Earth's Moon?<br /><br />--- http://jatslo.com/ : Jatslo

<i>To create that permanent beachhead, we must focus on the Moon. The Moon can be reached; the base there can grow incrementally and return benefits -- all in a more conceivable time frame. The most attractive feature of making the Moon the first permanent off-world human outpost is its proximity to Earth. The Moon is close, a couple of days away; Mars is many months farther.</i><br /><br /><br />--- http://www.space.com/adastra/adastra_moon_050215.html<br />

There is no firm data to support the idea, however. But astronomers say the Sun might have been closer to other stars in the past. A similar blast within 10 light-years of Earth "would destroy the ozone layer," according to a CfA statement, "causing abrupt climate change and mass extinctions due to increased radiation.</i> "<br /><br />--- http://www.space.com/scienceastronomy/bright_flash_050218.html<br /><br />The above link is that planet killer you were talking about, on the above thread.
