Supply water to the lunar base will be a comet

Future lunar base should be provided with water by means of "hunting" on the small comet, each of which may contain hundreds of tons of water ice — it's easier and more efficient than production of ice in the polar regions of the moon, according to the Institute of Astronomy of the Russian Academy of Sciences Alexander Bagrov and head of the St. Petersburg KB "Arsenal" Michael Kislitsky.

Data obtained with robotic probes in recent years have shown that in the polar regions of the moon, which is almost never looks the sun, can be hundreds of millions of tons of ice. This greatly facilitates the supply of future manned lunar bases. Water can be used not only for drinking — by expanding it into hydrogen and oxygen can be rocket fuel.

However Bagrov and Kislitsky believe that rely on the lunar "permafrost" is not worth it. "Extraction of water from the frozen regolith will be very difficult technically, as the strength of ice at low temperatures comparable with the strength of steel" — they wrote in a report prepared for the conference "King reading."

Moon bases in polar regions would be deprived of a source of energy — solar radiation. Scientists propose catch "minikomety" flying near the Moon — about 40,000 meter-sized bodies in the year, 80% consisted of ice. Scientists propose to deliver on the core of comets engines that operate by solar energy, and as the working medium is cometary methane.

"… This technique can be used to deliver minikomety the scope of the gravitational action of the moon. If minikometu translate into lunar orbit, the distillation can be held directly on the lunar orbit, separating water and methane," — they say.
