As normally happens in a diverse scientific community, the interpretations of specialized lunar data have reflected the precepts in the various specialized fields. Constant promotion of the broadest overviews between these diverse fields is appropriate to identify processes or phenomenon recog- nized in one avenue of investigation which may have great importance in explaining the data of other specialities. -

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. -

Martian Crater Morphology
ANALYSIS OF THE DEPTH-DIAMETER RELATIONSHIP OF MARTIAN CRATERS A Capstone Experience Thesis Presented by Jared Howenstine Completion Date: May 2006 Approved By: Professor M. Darby Dyar, Astronomy Professor Christopher Condit, Geology Professor Judith Young, Astronomy Abstract Title: Analysis of the Depth-Diameter Relationship of Martian Craters Author: Jared Howenstine, Astronomy Approved By: Judith Young, Astronomy Approved By: M. Darby Dyar, Astronomy Approved By: Christopher Condit, Geology CE Type: Departmental Honors Project Using a gridded version of maritan topography with the computer program Gridview, this project studied the depth-diameter relationship of martian impact craters. The work encompasses 361 profiles of impacts with diameters larger than 15 kilometers and is a continuation of work that was started at the Lunar and Planetary Institute in Houston, Texas under the guidance of Dr. Walter S. Keifer. Using the most ‘pristine,’ or deepest craters in the data a depth-diameter relationship was determined: d = 0.610D 0.327 , where d is the depth of the crater and D is the diameter of the crater, both in kilometers. This relationship can then be used to estimate the theoretical depth of any impact radius, and therefore can be used to estimate the pristine shape of the crater. With a depth-diameter ratio for a particular crater, the measured depth can then be compared to this theoretical value and an estimate of the amount of material within the crater, or fill, can then be calculated. The data includes 140 named impact craters, 3 basins, and 218 other impacts. The named data encompasses all named impact structures of greater than 100 kilometers in diameter. -

Introduction: Polygonal impact craters (PICs) re- flect pre-existing extensional and strike-slip faults and fractures in the target material [e.g. 1-9]. PIC straight rim segments therefore can provide important infor- mation for deciphering the tectonic histories of plane- tary bodies [e.g. 8]. The only known PIC formation mechanism is the presence of pre-existing sub-vertical structures within the target material [e.g. 5, 7, 11-13]. In contrast, circular impact craters (CICs) are in- ferred to result from impact events in non-tectonized target material. CICs can also form in pre-fractured tar- get material if the fractures are widely or closely spaced, if the fracture system is highly complex, or if the target material is covered by a thick layer of non-cohesive sed- iment that limits interactions between the impactor and the underlying bedrock/ice [e.g. 14]. Consequently, PICs and CICs are useful tools to distinguish between Fig. -
MDRS Final Summary Report – Crew 78 Vincent Beaudry, Kathryn Denning, Judah Epstein, Dirk Geeroms, Balwant Rai, Grier Wilt
MDRS final summary report – Crew 78 Vincent Beaudry, Kathryn Denning, Judah Epstein, Dirk Geeroms, Balwant Rai, Grier Wilt Introduction If interplanetary colonization is to be possible, humanity needs to learn as much as possible about how to rise to the challenges involved. One way to achieve this is, of course, through simulations. Our crew, the 78th in the Mars Desert Research Station simulation, was intensively international, composed of 2 Canadians (Kathryn Denning, Vincent Beaudry), 2 Americans (Judah Epstein, Grier Wilt), one Belgian (Dirk Geeroms) and one Indian (Balwant Rai). None of us had met before, and joining together to overcome language barriers and explore cultural differences provided us with an intense intercultural experience, surely akin to those which will be a part of future space exploration. As a group, we: developed our own knowledge of the challenges of space exploration; contributed to some ongoing MDRS research into extremophiles, environmental impact, and plant growth; furthered our individual projects in human physiology, long-distance teaching, and anthropology; acted as subjects for outside human factors researchers; and worked together to make life at the Hab go smoothly, including making some improvements to the Hab and to the EVA equipment. The Group Our crew was comprised of 6 individuals, with the following specialties: Vincent Beaudry was the commander, Judah Epstein the engineer and executive officer, Balwant Rai the scientist and health and security officer, Grier Wilt our biologist, Dirk Geeroms the teacher and astronomer, and Kathryn Denning our anthropologist and journalist. Although we all had our respective roles within this two weeks journey, we all enjoyed very much taking part in each others experiences and in the everyday tasks. -

Sawyer Laboratoire Magmas et Volcans, Université Blaise Pascal 5 rue Kessler, 63038 Clermont Ferrand, France and Istituto Nazionale di Geofisica e Vulcanologia Via della Faggiola, 32 56123 Pisa, Italy Domenico Granieri Istituto Nazionale di Geofisica e Vulcanologia Via della Faggiola, 32 56123 Pisa, Italy INTRODUCTION: VOLCANIC CO2 EMISSIONS IN THE GEOLOGICAL CARBON CYCLE Over long periods of time (~Ma), we may consider the oceans, atmosphere and biosphere as a single exospheric reservoir for CO2. The geological carbon cycle describes the inputs to this exosphere from mantle degassing, metamorphism of subducted carbonates and outputs from weathering of aluminosilicate rocks (Walker et al. 1981). A feedback mechanism relates the weathering rate with the amount of CO2 in the atmosphere via the greenhouse effect (e.g., Wang et al. 1976). An increase in atmospheric CO2 concentrations induces higher temperatures, leading to higher rates of weathering, which draw down atmospheric CO2 concentrations (Ber- ner 1991). Atmospheric CO2 concentrations are therefore stabilized over long timescales by this feedback mechanism (Zeebe and Caldeira 2008). This process may have played a role (Feulner et al. 2012) in stabilizing temperatures on Earth while solar radiation steadily increased due to stellar evolution (Bahcall et al. 2001). In this context the role of CO2 degassing from the Earth is clearly fundamental to the stability of the climate, and therefore to life on Earth. -
