ABSTRACT (MaxJmom 200wor_) For the 27th consecutive year, a NASA/ASEE Summer Faculty Fellowship Program was conducted at the Marshall Space Flight Center (MSFC). The program was conducted by The University of Alabama in Huntsville and MSFC during the period June 3, 1991 through August 9, 1991. Operated under the auspices of the American Society for Engineering Education, the MSFC program, as well as those at other NASA center_ was sponsored by the Office of Educational Affairs, NASA Headquarters, Washington, D.C. The basic objectives of the programs, which are in the 28th year of operatior nationally, are (i) to further the professional knowledge of qualified engineering and science faculty members; (2) to stimulate an exchange of ideas between par- ticipants and NASA; (3) to enrich and refresh the research and teaching activities of the participants' institutions; and (4) to contribute to the research objectives of the NASA centers. The Faculty Fellows spent 10 weeks at MSFC engaged in a research project compatible with their interests and background and worked in collaboration with a NASA/MSFC colleague. This document is a compilation of their research reports for summer 19_ Further information can be obtained by contacting any of the editors. 14. SUBJECT TERMS 15.

  • 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.

Krekeler 2 1 Department of Geology and Environmental Earth Sciences, 203 Shideler Hall, Miami University, Oxford, OH 45056, USA 2 Department of Geology and Environmental Earth Science, Miami University-Hamilton, Hamilton, OH 45011, USA; [email protected] * Correspondence: [email protected]; Tel.: 513-529-9662; Fax: 513-529-1542 Received: 10 June 2017; Accepted: 18 August 2017; Published: 23 August 2017 Abstract: The resource budget of Earth is limited. Rare-earth elements (REEs) are used across the world by society on a daily basis yet several of these elements have <2500 years of reserves left, based on current demand, mining operations, and technologies. With an increasing population, exploration of potential extraterrestrial REE resources is inevitable, with the Earth’s Moon being a logical first target. Following lunar differentiation at ~4.50–4.45 Ga, a late-stage (after ~99% solidification) residual liquid enriched in Potassium (K), Rare-earth elements (REE), and Phosphorus (P), (or “KREEP”) formed. Today, the KREEP-rich region underlies the Oceanus Procellarum and Imbrium Basin region on the lunar near-side (the Procellarum KREEP Terrain, PKT) and has been tentatively estimated at preserving 2.2 × 108 km3 of KREEP-rich lithologies. The majority of lunar samples (Apollo, Luna, or meteoritic samples) contain REE-bearing minerals as trace phases, e.g., apatite and/or merrillite, with merrillite potentially contributing up to 3% of the PKT. Other lunar REE-bearing lunar phases include monazite, yittrobetafite (up to 94,500 ppm yttrium), and tranquillityite (up to 4.6 wt % yttrium, up to 0.25 wt % neodymium), however, lunar sample REE abundances are low compared to terrestrial ores.

    SMITHSONIAN MISCELLANEOUS COLLECTIONS VOLUME 76. NUMBER 9 THE BRIGHTNESS OF LUNAR ECLIPSES 1860-1922 BY WILLARD J. FISHER (Publication 2751) CITY OF WASHINGTON PUBLISHED BY THE SMITHSONIAN INSTITUTION FEBRUARY 18, 1924 BALTIMORE, MD., II. S. A. THE BRIGHTNESS OF LUNAR ECLIPSES 1860-1922 By WILLARD J. FISHER After Struve and Dollen had pointed out the advantages in observ- ing occultations of faint stars during lunar total eclipses, and had circulated data facilitating the observations, there was an interest aroused among professional astronomers, who paid much attention to eclipse occultations for a considerable time ; but only a few, as Flammarion, Barnard, M. Wolf, paid much regard to lunar eclipse phenomena in relation to the earth's atmosphere. The observation and description of the peculiarities of the earth's shadow, both before and after the occupation campaign, was largely left to amateurs. The organization and growth of great societies, like the Societe Astronomique de France and the British Astronomical Association, have greatly increased the number of such observers and the volume of the recorded observations. The present paper was undertaken with the expectation that in the mass of lunar eclipse literature there would be found evidence of a structure of the earth's shadow corresponding to the known dust layers of the atmosphere.'' It was found that this object could not immediately be attained ; rather, it seemed desirable first to study the brightness of recorded eclipses. This, to be sure, has been done by A. Danjon,^ in papers in which, from a study of records going back to 1583, he has drawn the conclusion that there is a remarkable relation between the solar cycle and the brightness of lunar eclipses, mostly total.
