  • 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.

    E HARVARD COLLEGE OBSERVATORY Cambridge, Massachusetts 02138 INTERIM REPORT NO. 2 on e NGR 22-007-194 LUNAR NOMENCLATURE Donald H. Menzel, Principal Investigator to c National Aeronautics and Space Administration Office of Scientific and Technical Information (Code US) Washington, D. C. 20546 17 August 1970 e This is the second of three reports to be submitted to NASA under Grant NGR 22-007-194, concerned with the assignment I of names to craters on the far-side of the Moon. As noted in the first report to NASA under the subject grant, the Working Group on Lunar Nomenclature (of Commission 17 of the International Astronomical Union, IAU) originally assigned the selected names to features on the far-side of the Moon in a . semi-alphabetic arrangement. This plan was criticized, however, by lunar cartographers as (1) unesthetic, and as (2) offering a practical danger of confusion between similar nearby names, par- ticularly in oral usage by those using the maps in lunar exploration. At its meeting in Paris on June 20 --et seq., the Working Group accepted the possible validity of the second criticism above and reassigned the names in a more or less random order, as preferred by the cartographers. They also deleted from the original list, submitted in the first report to NASA under the subject grant, several names that too closely resembled others for convenient oral usage. The Introduction to the attached booklet briefly reviews the solutions reached by the Working Group to this and several other remaining problems, including that of naming lunar features for living astronauts.

  • Precambrian Lunar Volcanic Protolife
    Int. J. Mol. Sci. 2009, 10, 2681-2721; doi:10.3390/ijms10062681 OPEN ACCESS International Journal of Molecular Sciences ISSN 1422-0067 www.mdpi.com/journal/ijms Review Precambrian Lunar Volcanic Protolife Jack Green Department of Geology, California State University, Long Beach, California, 90840, USA; E-Mail: [email protected]; Tel. +1-562-985-4198; Fax: +1-562-985-8638 Received: 29 April 2009; in revised form: 28 May 2009 / Accepted: 3 June 2009 / Published: 11 June 2009 Abstract: Five representative terrestrial analogs of lunar craters are detailed relevant to Precambrian fumarolic activity. Fumarolic fluids contain the ingredients for protolife. Energy sources to derive formaldehyde, amino acids and related compounds could be by flow charging, charge separation and volcanic shock. With no photodecomposition in shadow, most fumarolic fluids at 40 K would persist over geologically long time periods. Relatively abundant tungsten would permit creation of critical enzymes, Fischer-Tropsch reactions could form polycyclic aromatic hydrocarbons and soluble volcanic polyphosphates would enable assembly of nucleic acids. Fumarolic stimuli factors are described. Orbital and lander sensors specific to protolife exploration including combined Raman/laser-induced breakdown spectrocsopy are evaluated. Keywords: fumaroles; protolife; caldera; energy sources; polymerase chain reaction; lunar sensors 1. Introduction This paper is limited to volcanic processes and is tied in to terrestrial analogs modified by lunar environmental constraints. As with many geological systems, the fumarolic environment represents an open system—the broken test tube, the defective blast furnace. Moreover, pure reagents are virtually unknown in nature and variability is the rule. Tidal and gravity effects may have played a major role in intensifying Hadean-Archean lunar volcanism [1] as they have on Io.
