	Moon (Site not responding. Last check: 2007-10-06)
		The plane of the lunar Orbit maintains an inclination of 5.145 396° with respect to the ecliptic (the orbital plane of the Earth), and the lunar axis of rotation maintains an inclination of 1.5424° with respect to the normal to that same plane.
		This crater is located on the far side, near the south pole, and is some 2,240 km in diameter, and 13 km in depth.

	TIMS 1992 Extended Abstract
		Within the horizontal sedimentary sequence that forms the upper Colorado Plateau, the oldest unit sampled by the impact crater was the Permian Coconino Sandstone.
		Particles between 355 and 500 microns were used to reduce the effects of volume scattering; the choice of endmember minerals approximates the mixing of Kiabab Limestone and Coconino Sandstone in the crater ejecta.

	The Bruce Medalists: Walter S. Adams
		Walter Adams was born in Syria, the son of American missionaries.
		His spectroscopic studies of the sun and stars led to the discovery, with Arnold Kohlschütter, of a spectroscopic method for determining stellar distances: they showed that the relative intensities of spectral lines could be used to determine absolute magnitudes of both giant and main sequence stars.

		Through screening of at least half of the meteorite flow and ionising radiation, the equipment lifetime on the lunar surface may be at least twice as long as that of a spacecraft in orbit.
		Lunar soil can be used to support life of the station personnel, thermal control and repair of equipment.
		For example, an unusual formation near the crater Lovelace (117º W; 82º N), which was photographed by the HIRES camera of the space probe Clementine, image LHD30055.080 (fig.1), seems to be a promising candidate for archaeological reconnaissance.

		Already pocked with thousands upon thousands of craters from asteroid impacts over billions of years, the moon's new artificial craters will be created by two "impactors" riding aboard a spacecraft called the Lunar Reconnaissance Orbiter.
		Instruments aboard two recent moon-orbiting missions - named Lunar Prospector and Clementine - have detected hints of hydrogen and possibly water ice deep within the permanently shadowed bottoms of craters near the moon's north and south poles, Colaprete said.
		The Shackleton crater has often been mentioned as a possible site for a manned lunar base and a jumping-off place for manned missions to Mars - if ever President Bush's "Vision for Space Exploration" is finally realized.

		The craters and the fragmental debris were probably formed by bombardment of the lunar surface by meteoroids and by pieces of the Moon itself, hurled through space from larger craters.
		The crater, one of hundreds of thousands of this type on the Moon, is much akin to the well-known Meteor Crater in Arizona; namely, caused by the impact of an outside mass.
		Chemical analysis in the lunar highlands, by the crater Tycho, differed in that the concentration of iron and neighboring heavy elements was only half or less than that found in the maria.

		Although each began near the center of the crater, and extended in a shaft of light to the western wall, it was clear that each was positioned in line with a gap or notch in the eastern wall of Plato.
		I have seen many lunar rays before, but three sunrise rays all at once in a crater like Plato made a grand sight.
		Thus the observing report by Adams stating it was on the west wall, for modern orientation, makes the observation on the eastern wall.)

		The French mathematician Urbain Le Verrier, co-predictor with J.C. Adams of the position of Neptune before it was seen, in an 1860 lecture announced that the problem of observed deviations of the motion of Mercury could be solved by assuming a planet or a second asteroid belt inside Mercury's orbit.
		An impact 65 million years ago by an object of 5--10 km in diameter is thought to have been partially or fully responsible for the extinction of half the living species of animals and plants at the time, including the dinosaurs.
		The crater alone from such an impact will be 10--15 times larger than the object itself.
