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. -
January 2019 Cardanus & Krafft
A PUBLICATION OF THE LUNAR SECTION OF THE A.L.P.O. EDITED BY: Wayne Bailey [email protected] 17 Autumn Lane, Sewell, NJ 08080 RECENT BACK ISSUES: http://moon.scopesandscapes.com/tlo_back.html FEATURE OF THE MONTH – JANUARY 2019 CARDANUS & KRAFFT Sketch and text by Robert H. Hays, Jr. - Worth, Illinois, USA September 24, 2018 04:40-05:04 UT, 15 cm refl, 170x, seeing 7/10, transparence 6/6. I drew these craters and vicinity on the night of Sept. 23/24, 2018. The moon was about 22 hours before full. This area is in far western Oceanus Procellarum, and was favorably placed for observation that night. Cardanus is the southern one of this pair and is of moderate depth. Krafft to the north is practically identical in size, and is perhaps slightly deeper. Neither crater has a central peak. Several small craters are near and within Krafft. The crater just outside the southeast rim of Krafft is Krafft E, and Krafft C is nearby within Krafft. The small pit to the west is Krafft K, and Krafft D is between Krafft and Cardanus. Krafft C, D and E are similar sized, but K is smaller than these. A triangular-shaped swelling protrudes from the north side of Krafft. The tiny pit, even smaller than Krafft K, east of Cardanus is Cardanus E. There is a dusky area along the southwest side of Cardanus. Two short dark strips in this area may be part of the broken ring Cardanus R as shown on the. Lunar Quadrant map. -

Vegetative Ecology of a Montane Mire, Crater Lake National
AJ ABSTRACT OF THE THESIS OF Susan Cornelia Seyer for the degree of Master of Science in Botany and Plant Pathology presented on December 14, 1979 Title: VEGETATIVE ECOLOGY OF A MONTANE MIRE, CRATER LAKE NATIONAL PARK, OREGON Redacted for Privacy Abstract approved: Jerry F. Franklin Mires, or peat-producing ecosystems, dominated by sedges, shrubs, and brown mosses, are common features in Cascade subalpine regions, occurring where moisture accumulates in small basins or on poorly-drained slopes. Although descriptions and classifications have been developed for mire vegetation in much of the world, there is little information of even a descriptive nature for these montane mires in Oregon and Washington. This thesis reports on phytosocia- logical structure, env'ironental relations, and successional trends in one such mire in the Oregon Cascade mountains. To characterize the general phytosociological structure of the mire vegetation at Sphagnum Bog, Crater Lake National Park, quantitative species cover data were used in conjunction with a Braun-Blanquet tabular analysis and two-dimensional stand ordinations, reciprocal averaging and a Bray-Curtis polar ordination. Defined community types correspond to physiognomic types as follows: Carex rostrata (reedswamp); Eleocharis pauciflora-Carex limosa, Eleocharis pauciflora/bryophytes (low sedge fens); Carex sichensis (tall sedge fen); Vaccinium/ Aulacomnium palustre, Vaccinium occidentala/Carex sitchensis (shrub thickets; Alnus incana/Brachythacium sp. and Salix barclayi (marginal carrs).Phases were defined when appropriate. A vegetation map was made to illustrate the locations and extent of the variouscommunities. Comparisons with other montane mires in thearea determined that the physiognomic units defined are repeatable when appropriate habitat conditions are present, and that they usually includemany of the same characteristic species, the dominant mosses being particularly constant. -

LUNAR TOPOGRAPHIC ORTHOPHOTOMAP (LTO) AND LUNAR ORTHOPHOTMAP (LO) SERIES (Published by DMATC) Lunar Topographic Orthophotmaps and Lunar Orthophotomaps Scale: 1:250,000 Projection: Transverse Mercator Sheet Size: 25.5”x 26.5” The Lunar Topographic Orthophotmaps and Lunar Orthophotomaps Series are the first comprehensive and continuous mapping to be accomplished from Apollo Mission 15-17 mapping photographs. This series is also the first major effort to apply recent advances in orthophotography to lunar mapping. Presently developed maps of this series were designed to support initial lunar scientific investigations primarily employing results of Apollo Mission 15-17 data. Individual maps of this series cover 4 degrees of lunar latitude and 5 degrees of lunar longitude consisting of 1/16 of the area of a 1:1,000,000 scale Lunar Astronautical Chart (LAC) (Section 4.2.1). Their apha-numeric identification (example – LTO38B1) consists of the designator LTO for topographic orthophoto editions or LO for orthophoto editions followed by the LAC number in which they fall, followed by an A, B, C or D designator defining the pertinent LAC quadrant and a 1, 2, 3, or 4 designator defining the specific sub-quadrant actually covered. The following designation (250) identifies the sheets as being at 1:250,000 scale. The LTO editions display 100-meter contours, 50-meter supplemental contours and spot elevations in a red overprint to the base, which is lithographed in black and white. LO editions are identical except that all relief information is omitted and selenographic graticule is restricted to border ticks, presenting an umencumbered view of lunar features imaged by the photographic base. -

The principal point of this program was a detailed scientific analysis of the orbital and surface experiments data derived from Apollo missions 15, 16, and 17. One of the requirements of this program was the production of detailed photo base maps at a useable scale. NASA in conjunction with the Defense Mapping Agency (DMA) commenced a mapping program in early 1973 that would lead to the production of the necessary maps based on the need for certain areas. This paper is designed to present in outline form the neces- sary background informatiox or users to become familiar with the program. MAP FORMAT * The scale chosen for the project was 1:250,000 . The re- search being done required a scale that Principal Investigators (PI'S) using orbital photography could use, but would also serve PI'S doing surface photographic investigations. Each map sheet covers an area four degrees north/south by five degrees east/west. -

TARGET-DEPENDENCE OF CRATER DEPTH ON THE MOON. Richard J. Pike, U.S. Geological Survey, Menlo Park, CA 94025. Head (1976) has developed and amplified Wegener's (1921) concept that layering of the target can affect the morphology of large impact craters. Head's model attributes the differences between simple (small) and complex (large) craters to presence of a thick and "soft" megaregolith over a "hard" substrate. The idea has met with some resistance (e.g., Floran and Dence, 1976) because the megaregolith must be absent over much of the maria, and the expected depth/diameter (d/~)differences between craters on the maria and those on the uplands were not observed (Quaide et al. , 1965; Pike, 1974). Although Marcus (1967) and Pike (1977) had found complex upland craters to be slightly deeper than complex mare craters, the data were meager, and both authors dismissed the differences as insignificant . Table 1 The most recent measurements, improved over those available for the latter four studies, have demonstra- ted that fresh complex craters on the lunar uplands clu. D d are indeed deeper than those on mare surfaces (Wood om' *) and Andersson, 1978; Croft, 1978; Pike, 1980a; DeHon, bp.4~- 93.0 3.80 1980).
