Orontius (crater) Orontius is a lunar impact crater that lies in the heavily cratered southern highlands of the Moon's near side. It is located to the northwest of the prominent ray crater Tycho, and south and east of the large walled plain Deslandres. The eastern part of the crater is overlain by the smaller crater Huggins, which is overlain in turn on its eastern rim by the still smaller Nasireddin, the trio forming a crater chain of diminishing dimensions. Joined to the southern rim is the crater Saussure. To the Category:Orontius (crater). From Wikimedia Commons, the free media repository. Jump to navigation Jump to search.

The crater is heavily eroded and the crater rim twice superimposed (east of Huggins and west by Sasse Rides A), which is why he is unremarkable, despite a diameter of about 90 kilometers. The crater was officially named by the IAU in 1935 by the French mathematician and cartographer Oronce FinÃ©. Orontius (crater).

A pair of craters to the west have intruded into the crater wall, forming inward bulges. Little of the original wall remains nearly intact, with the south and southwestern rim having survived the erosion process better than the other wall sections Found on http://en.wikipedia.org/wiki/Orontius_(crater).

RADAR POLARIZATION PROPERTIES AND LUNAR SECONDARY CRATERING A Dissertation Presented to the Faculty of the Graduate School of Cornell University In Partial Fulfillment of the Requirements for the Degree of Doctor of Philosophy by Kassandra Martin-Wells January 2013 © 2013 Kassandra Martin-Wells RADAR POLARIZATION PROPERTIES AND LUNAR SECONDARY CRATERING Kassandra Martin-Wells, Ph. D. Cornell University 2013 Age dating of planetary surfaces relies on an accurate correlation between lunar crater size-frequency distributions and radiometric ages of samples returned from the Moon. For decades, it has been assumed that cratering records are dominated by “primary” impacts of interplanetary bolides [McEwen et al., 2005]. Unlike primary craters, secondary craters, which originate as ejecta from large primary events, occur in large clusters in both space and time. It was long believed that the majority of secondary craters formed at low velocities near their parent crater, resulting in a class of craters with morphologies which are easily distinguished from primary craters of a similar size [McEwen et al., 2005]. However, recent work by Bierhaus et al. (2005), McEwen et al. (2005) argues that cratering records in the Solar System may be strongly contaminated by hard-to-identify secondary craters. They advise caution when relying on counts at small diameters [McEwen et al., 2005; Bierhaus et al., 2005]. Despite the difficulties, something must be done to improve the accuracy of age dates derived from size-frequency distributions of small craters. In this thesis, a method of secondary crater identification based on radar circular polarization properties is presented. The radar polarization and photographic studies of lunar secondary craters in this thesis reveal that secondary cratering is a widespread phenomenon on the lunar surface.

Glossary Glossary
Glossary Glossary Albedo A measure of an object’s reflectivity. A pure white reflecting surface has an albedo of 1.0 (100%). A pitch-black, nonreflecting surface has an albedo of 0.0. The Moon is a fairly dark object with a combined albedo of 0.07 (reflecting 7% of the sunlight that falls upon it). The albedo range of the lunar maria is between 0.05 and 0.08. The brighter highlands have an albedo range from 0.09 to 0.15. Anorthosite Rocks rich in the mineral feldspar, making up much of the Moon’s bright highland regions. Aperture The diameter of a telescope’s objective lens or primary mirror. Apogee The point in the Moon’s orbit where it is furthest from the Earth. At apogee, the Moon can reach a maximum distance of 406,700 km from the Earth. Apollo The manned lunar program of the United States. Between July 1969 and December 1972, six Apollo missions landed on the Moon, allowing a total of 12 astronauts to explore its surface. Asteroid A minor planet. A large solid body of rock in orbit around the Sun. Banded crater A crater that displays dusky linear tracts on its inner walls and/or floor. 250 Basalt A dark, fine-grained volcanic rock, low in silicon, with a low viscosity. Basaltic material fills many of the Moon’s major basins, especially on the near side. Glossary Basin A very large circular impact structure (usually comprising multiple concentric rings) that usually displays some degree of flooding with lava. The largest and most conspicuous lava- flooded basins on the Moon are found on the near side, and most are filled to their outer edges with mare basalts.

Carol Lakomiak's Astrosketching Tutorials - the Moon
Carol Lakomiak's Astrosketching Tutorials - the Moon Carol Lakomiak, veteran observer, BBC Sky at Night magazine's astrosketching columnist, and astrophotographer, shares her advice on how to draw what you observe. On a beautiful summer evening in 2003, crater Capuanus drifted into the eyepiece, and looked so lovely that I decided to try something entirely new―sketching. It was quite frustrating at first―I'd never had art lessons, so it was necessary to figure things out for myself. As time passed though, I developed this intuitive step-by-step technique, which has helped a lot of people throughout the years―I'm sure it will help you too. The crater group depicted is located east of Tycho, and includes craters Orontius, Sassure, Huggins, Nasireddin, and Miller. The sketch was made at the eyepiece on 2005 July 14th, and its progress was recorded with a digital camera. It was begun at 20:45 (just before sunset) and was finished an hour later at 21:45. The first two images were taken with sufficient daylight, but the last three required a hand-held light―that's why they vary so much regarding brightness, and overall illumination. To make things less intimidating at first, you might feel more comfortable practicing from the sketches shown here, or from lunar images. And don't give up. You didn't give up when learning to walk, tie your shoes, or ride a bike, so don't do it with sketching. Remember, the goal of eyepiece sketching is to record your observation―not to create a pretty picture.

Various exogenic and endogenic sources of this water have been proposed. This paper focuses on endogenic water sources by fumaroles and hot springs in shadowed polar craters. A survey of theoretical and morphological details supports a volcanic model. Release of water and other constituents by defluidization over geological time was intensified in the Hadean Eon (c.a. 4600 to 4000 My). Intensification factors include higher heat flow by now-extinct radionuclides, tidal flexing and higher core temperatures. Lesser gravity would promote deeper bubble nucleation in lunar magmas, slower rise rates of gases and enhanced subsidence of lunar caldera floors. Hadean volcanism would likely have been more intense and regional in nature as opposed to suture-controlled location of calderas in Phanerozoic Benioff-style subduction environments. Seventy-seven morphological, remote sensing and return sample features were categorized into five categories ranging from a volcano-tectonic origin only to impact origin only.

Tycho, at the Center of the Moon's Brightest and Most Extensive
Tycho, at the center of the Moon's brightest and craterlets or rilles worth mentioning on Tycho's most extensive system of rays, is the most obvious floor, just scattered rubble piles. The terrain around crater visible on the surface of the full moon, and the outside of Tycho is a different story, however, therefore as good a place as any to start exploring with innumerable craters of all sizes, many of them the southwest quadrant. Tycho is a huge walled in chains, pocking the landscape. One particularly plain, 90 km (56 miles) in diameter, its walls soaring interesting crater chain southwest of the main crater an impressive 3500 m (12 000 ft) above its floor, is made up of at least seven different craters with capped with peaks 1500 m (5000 ft) high.

Notes on Geologic History of the Moon
The Geological History of the Moon (1987) U.S. Geological Survey Professional Paper 1348 http://ser.sese.asu.edu/GHM/ I have read this fascinating account of the geology of the Moon and have extracted parts of it and edited it for our 4-H astronomy project. You can get the complete story for free using the link above. Figure 1 near side of the Moon Figure 2 far side of the Moon When I was a child, astronomers had never seen the far side of the Moon. Imagine their surprise when the Soviet probe named Luna 3 sent back the first images of the hidden side in early October, 1959. I think Galileo would have been surprised as well if he was living then. The most obvious geological features on the Moon are the dark seas. The darker shade of the seas is due to the type of rock found there. It is volcanic rock called basalt. Remarkably, nearly all of the seas (called maria) are located on the near side of the Moon. About 30% of the near side is covered with maria while only 2% of the far side is covered with maria. If you look carefully at the near side photo above, you might notice that the seas are mostly circular in shape. Some overlap each other, especially on the west side (to the left). The seas are actually huge craters that were filled with lava seeping out from the interior of the Moon. It is believed that the crust of the Moon is thinner on the near side than the far side.
