More water on the moon.



Researchers analyzing data from the Lunar Prospector The Lunar Prospector mission was the third selected by NASA for full development and construction as part of the Discovery Program. At a cost of $62.8 million, the 19-month mission was designed for a low polar orbit investigation of the Moon, including mapping of surface , the tiny robot that has been orbiting the moon since January, have drastically upped their estimate of the amount of frozen water buried beneath the lunar poles. In March, the Prospector team suggested that craters in permanent shadow at the north and south poles North and South Poles

 could hide 300 million metric tons of ice (SN: 3/14/98, p. 166). After refining models of how water might be delivered to the surface, the team now says that the poles may contain as much as 600 billion metric tons, with the north pole North Pole, northern end of the earth's axis, lat. 90°N. It is distinguished from the north magnetic pole. U.S. explorer Robert E. Peary is traditionally credited as being the first to reach (1909) the North Pole. In 1926, Richard E.  harboring perhaps 15 percent more of the precious resource than the south.

The U.S.  (N.M.) National Laboratory and his colleagues report the new findings in the Sept. 4 SCIENCE. The evidence is indirect. Prospector's measurements indicate that the poles have a higher abundance of hydrogen than elsewhere on the moon, and the team asserts that the hydrogen is almost certainly tied up in water.
