  • 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.

  • Planetary Surfaces
    Chapter 4 PLANETARY SURFACES 4.1 The Absence of Bedrock A striking and obvious observation is that at full Moon, the lunar surface is bright from limb to limb, with only limited darkening toward the edges. Since this effect is not consistent with the intensity of light reflected from a smooth sphere, pre-Apollo observers concluded that the upper surface was porous on a centimeter scale and had the properties of dust. The thickness of the dust layer was a critical question for landing on the surface. The general view was that a layer a few meters thick of rubble and dust from the meteorite bombardment covered the surface. Alternative views called for kilometer thicknesses of fine dust, filling the maria. The unmanned missions, notably Surveyor, resolved questions about the nature and bearing strength of the surface. However, a somewhat surprising feature of the lunar surface was the completeness of the mantle or blanket of debris. Bedrock exposures are extremely rare, the occurrence in the wall of Hadley Rille (Fig. 6.6) being the only one which was observed closely during the Apollo missions. Fragments of rock excavated during meteorite impact are, of course, common, and provided both samples and evidence of co,mpetent rock layers at shallow levels in the mare basins. Freshly exposed surface material (e.g., bright rays from craters such as Tycho) darken with time due mainly to the production of glass during micro- meteorite impacts. Since some magnetic anomalies correlate with unusually bright regions, the solar wind bombardment (which is strongly deflected by the magnetic anomalies) may also be responsible for darkening the surface [I].

  • Feature of the Month - August 2006
    RECENT BACK ISSUES: http://www.zone-vx.com/tlo_back.html A PUBLICATION OF THE LUNAR SECTION OF THE A.L.P.O. EDITED BY: William M. Dembowski, F.R.A.S. - [email protected] Elton Moonshine Observatory - http://www.zone-vx.com 219 Old Bedford Pike (Elton) - Windber, PA 15963 FEATURE OF THE MONTH - AUGUST 2006 RHEITA E Sketch and text by Robert H. Hays, Jr. - Worth, Illinois, USA March 5, 200 - 01:15 to 01:45 UT 15cm Newtonian - 170x - Seeing 7-8/10 I sketched this crater and vicinity on the evening of March 4, 2006 after observing two occultations. This feature is located amid a jumble of craters south of Mare Fecunditatis. This is an elongated crater that appears to be the result of at least three impacts. The north and south lobes are about the same size, but the southern lobe is definitely deeper. The central portion is about the size of the north and south lobes combined. There are some bits of shadow on the floor, but I saw no obvious hills or craters there. I have drawn the shadowing within and around Rheita E as I saw it. There is an obvious ridge extending westward from the south lobe. The crater Rheita F is adjacent to the south lobe of Rheita E, and has a strip of shadow parallel to the ridge from Rheita E. Rheita M is the large, shallow crater east of Rheita E's south end, and Rheita N is the small, shallow pit between them. Stevinus D is the slightly smaller, but deeper crater north of Rheita M.

    OCTOBER 2 0 0 6 �������������� http://www.universetoday.com �������������� TAMMY PLOTNER WITH JEFF BARBOUR 283 SUNDAY, OCTOBER 1 In 1897, the world’s largest refractor (40”) debuted at the University of Chica- go’s Yerkes Observatory. Also today in 1958, NASA was established by an act of Congress. More? In 1962, the 300-foot radio telescope of the National Ra- dio Astronomy Observatory (NRAO) went live at Green Bank, West Virginia. It held place as the world’s second largest radio scope until it collapsed in 1988. Tonight let’s visit with an old lunar favorite. Easily seen in binoculars, the hexagonal walled plain of Albategnius ap- pears near the terminator about one-third the way north of the south limb. Look north of Albategnius for even larger and more ancient Hipparchus giving an almost “figure 8” view in binoculars. Between Hipparchus and Albategnius to the east are mid-sized craters Halley and Hind. Note the curious ALBATEGNIUS AND HIPPARCHUS ON THE relationship between impact crater Klein on Albategnius’ southwestern wall and TERMINATOR CREDIT: ROGER WARNER that of crater Horrocks on the northeastern wall of Hipparchus. Now let’s power up and “crater hop”... Just northwest of Hipparchus’ wall are the beginnings of the Sinus Medii area. Look for the deep imprint of Seeliger - named for a Dutch astronomer. Due north of Hipparchus is Rhaeticus, and here’s where things really get interesting. If the terminator has progressed far enough, you might spot tiny Blagg and Bruce to its west, the rough location of the Surveyor 4 and Surveyor 6 landing area.

  • Moon Viewing Guide
    MMoooonn MMaapp What lunar features can you find? Use this Moon Map & Viewing Guide to explore different areas of the Moon - no binoculars needed! MMoooonn VViieewwiinngg GGuuiiddee A quick look at the Moon in the night sky – even without binoculars - shows light areas and dark areas that reveal lunar history. Can you find these features? Use the Moon Map (above) to help. Sea of Tranquility (Mare Tanquilitatus) – Formed when a giant t! nd I asteroid hit the Moon almost 4 billion years ago, this 500-mile wide Fou dark, smooth, circular basin is the site of the Apollo 11 landing in 1969. Sea of Rains (Mare Imbrium) – Imbrium Basin is the largest t! nd I basin on the Moon that was formed by a giant asteroid almost 4 Fou billion years ago. Sea of Serenity (Mare Serenitatis) – Apollo 17 astronauts t! sampled some of the oldest rocks on the Moon from edges of nd I Fou the Sea of Serenity. These ancient rocks formed in the Moon’s magma ocean. Lunar Highlands – The lighter areas on the Moon are the lunar t! highlands. These are the oldest regions on the Moon; they formed nd I Fou from the magma ocean. Because they are so old, they have been hit by impact craters many times, making the highlands very rough. Want an extra challenge? If you have a telescope or pair of binoculars, try finding these features: Appenine Mountains (Montes Apenninus) – Did you know there are mountain ranges on the Moon? The rims of the craters and t! nd I basins rise high above the Moon’s surface.
