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. -

Radar Remote Sensing of Pyroclastic Deposits in the Southern Mare Serenitatis and Mare Vaporum Regions of the Moon Lynn M
JOURNAL OF GEOPHYSICAL RESEARCH, VOL. 114, E11004, doi:10.1029/2009JE003406, 2009 Click Here for Full Article Radar remote sensing of pyroclastic deposits in the southern Mare Serenitatis and Mare Vaporum regions of the Moon Lynn M. Carter,1 Bruce A. Campbell,1 B. Ray Hawke,2 Donald B. Campbell,3 and Michael C. Nolan4 Received 21 April 2009; revised 12 July 2009; accepted 3 August 2009; published 5 November 2009. [1] We use polarimetric radar observations to study the distribution, depth, and embedded rock abundance of nearside lunar pyroclastic deposits. Radar images were obtained for Mare Vaporum and the southern half of Mare Serenitatis; the imaged areas contain the large Rima Bode, Mare Vaporum, Sulpicius Gallus, and Taurus-Littrow pyroclastic deposits. Potential pyroclastic deposits at Rima Hyginus crater, the Tacquet Formation, and a dome in Mare Vaporum are also included. Data were acquired at S band (12.6 cm wavelength) using Arecibo Observatory and the Green Bank Telescope in a bistatic configuration. The S band images have resolutions between 20 and 100 m/pixel. The pyroclastic deposits appear dark to the radar and have low circular polarization ratios at S band wavelengths because they are smooth, easily penetrable by radar waves, and generally contain few embedded blocks. Changes in circular polarization ratio (CPR) across some of the pyroclastic deposits show areas with increased rock abundance as well as deposits that are shallower. Radar backscatter and CPR maps are used to identify fine-grained mantling deposits in cases where optical and near-infrared data are ambiguous about the presence of pyroclastics. -
10Great Features for Moon Watchers
Sinus Aestuum is a lava pond hemming the Imbrium debris. Mare Orientale is another of the Moon’s large impact basins, Beginning observing On its eastern edge, dark volcanic material erupted explosively and possibly the youngest. Lunar scientists think it formed 170 along a rille. Although this region at first appears featureless, million years after Mare Imbrium. And although “Mare Orien- observe it at several different lunar phases and you’ll see the tale” translates to “Eastern Sea,” in 1961, the International dark area grow more apparent as the Sun climbs higher. Astronomical Union changed the way astronomers denote great features for Occupying a region below and a bit left of the Moon’s dead lunar directions. The result is that Mare Orientale now sits on center, Mare Nubium lies far from many lunar showpiece sites. the Moon’s western limb. From Earth we never see most of it. Look for it as the dark region above magnificent Tycho Crater. When you observe the Cauchy Domes, you’ll be looking at Yet this small region, where lava plains meet highlands, con- shield volcanoes that erupted from lunar vents.

Update on Lunar Calibration Development and Applications
Update on Lunar Calibration Development and Applications Thomas C. Stone U.S. Geological Survey, Flagstaff, AZ USA CEOS WGCV IVOS-29 Meeting Tucson, Arizona 15 March 2017 Background — Overview of Lunar Calibration At reflected solar wavelengths, the Moon can be regarded as a solar diffuser, which has exceptionally stable reflectance. To use the Moon as a calibration reference requires an analytic model ― to predict the lunar brightness for any Moon observations made an instrument (i.e. the Sun-Moon-Observer geometry) ― the model comprises the lunar calibration reference To build a lunar photometric model requires a large set of characterization measurements of the Moon, spanning several years ― to capture the periodic brightness variations sufficiently for modeling ― the range of available Moon views is constrained by orbital mechanics Development of the lunar calibration system at USGS found the most useful radiometric quantity is the spatially integrated lunar irradiance. Lunar Model Development at USGS — ROLO A dedicated ground-based telescope facility — the Robotic Lunar Observatory (ROLO): • located at Flagstaff, AZ 2143 m altitude • acquired >110 000 Moon images in 32 multispectral bands • in operation more than 8 years Lunar disk reflectance model • empirically derived formulation • a function of only the geometric variables of phase and the lunar librations: Lunar Irradiance Model — Operation The fundamental model outputs (Ak) at 32 ROLO bands are fitted with a lunar reflectance spectrum, which is convolved with the instrument band spectral response functions and the solar spectrum to give the lunar irradiance (EM): The model computations (Afit) and ΩM are for standard Sun–Moon and Moon–Observer distances of 1 AU and 384400 km Apply distance corrections: The final output E′M is the lunar irradiance present at the instrument location at the time of the observation, in each sensor spectral band. -

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. -
Lunar Observation Lab: Understanding the Motion and Phases of the Moon Author: Sean S
Lunar Observation Lab: Understanding the motion and phases of the Moon Author: Sean S. Lindsay Version 1.1 created 1 September 2016 Learning Goals In this activity, you will learn the names for the phases of the Moon and that the phases are caused by the position of the Moon in its orbit with respect to the Sun and Earth. Students will also gain practical experience in naked-eye observations with detailed, recorded notes, including sketches. Specifically, students will: 1) Address the misconception that the phases of the Moon are caused by Earth’s shadow falling on the Moon. THIS IS NOT TRUE. The phases of the Moon are caused by the geometry between the Sun, Earth, and Moon. 2) Understand the connections of the phases of the Moon and what time the Moon is up in the sky. 3) Understand the difference between the synodic and sidereal periods of the Moon. 3) Learn how to accurately document observations. Lab Abstract The Lunar Observation Lab provides the student with practical experience in naked-eye observations of the Moon. The student will make detailed naked-eye observations of the Moon over a minimum of a five-week period. Specifically, the observations are to identify the phase of the Moon and its location in the sky (direction and altitude) over a time period slightly longer than full lunar cycle In doing so, the student will experience a full set of phases of the Moon and participate in a series of exercises design to increase understanding that the phases of the Moon are the result of the location of the Moon in its orbit relative to the Sun and the Earth. -
