This means that the next total lunar eclipse won't happen until 2021 (Asia).

  • 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.

  • Solar System Exploration: a Vision for the Next Hundred Years
    IAC-04-IAA.3.8.1.02 SOLAR SYSTEM EXPLORATION: A VISION FOR THE NEXT HUNDRED YEARS R. L. McNutt, Jr. Johns Hopkins University Applied Physics Laboratory Laurel, Maryland, USA [email protected] ABSTRACT The current challenge of space travel is multi-tiered. It includes continuing the robotic assay of the solar system while pressing the human frontier beyond cislunar space, with Mars as an ob- vious destination. The primary challenge is propulsion. For human voyages beyond Mars (and perhaps to Mars), the refinement of nuclear fission as a power source and propulsive means will likely set the limits to optimal deep space propulsion for the foreseeable future. Costs, driven largely by access to space, continue to stall significant advances for both manned and unmanned missions. While there continues to be a hope that commercialization will lead to lower launch costs, the needed technology, initial capital investments, and markets have con- tinued to fail to materialize. Hence, initial development in deep space will likely remain govern- ment sponsored and driven by scientific goals linked to national prestige and perceived security issues. Against this backdrop, we consider linkage of scientific goals, current efforts, expecta- tions, current technical capabilities, and requirements for the detailed exploration of the solar system and consolidation of off-Earth outposts. Over the next century, distances of 50 AU could be reached by human crews but only if resources are brought to bear by international consortia. INTRODUCTION years hence, if that much3, usually – and rightly – that policy goals and technologies "Where there is no vision the people perish.” will change so radically on longer time scales – Proverbs, 29:181 that further extrapolation must be relegated to the realm of science fiction – or fantasy.

In 2009 we started an intense radial-velocity monitoring of a few nearby, slowly-rotating and quiet solar-type stars within the dedicated HARPS-Upgrade GTO program. Aims. The goal of this campaign is to gather very-precise radial-velocity data with high cadence and continuity to detect tiny signatures of very-low-mass stars that are potentially present in the habitable zone of their parent stars. Methods. Ten stars were selected among the most stable stars of the original HARPS high-precision program that are uniformly spread in hour angle, such that three to four of them are observable at any time of the year.

  • Another Unit of Distance (I Like This One Better): Light Year
    How far away are the nearest stars? Last time: • Distances to stars can be measured via measurement of parallax (trigonometric parallax, stellar parallax) • Defined two units to be used in describing stellar distances (parsec and light year) Which stars are they? Another unit of distance (I like this A new unit of distance: the parsec one better): light year A parsec is the distance of a star whose parallax is 1 arcsecond. A light year is the distance a light ray travels in one year A star with a parallax of 1/2 arcsecond is at a distance of 2 parsecs.

Cravens Space Physics Research Laborator~, Department of Atmospheric and Oceanic Science, The University of Michigan, Ann Arbor, MI 48109, U.S.A. ABSTRACT Our understanding of the physical and chemical processes which control the behavior of the Venus ionosphere has advanced significantly during the last few years. These advances are the result of a still growing data base and a variety of evolving theoretical models. This review summarizes some of these recent studies, especially those concerning the dynamics of the ionosphere, the maintenance of the nightside ionosphere, the energetics of the nightside ionosphere, and the time evolution of magnetic fields in the dayside ionosphere. INTRODUCTION This paper gives a brief review of recent advances in our understanding of some of the basic physical processes controlling the behavior of the ionosphere of Venus. More specifically this review is limited to summaries of theoretical model studies related to: a) ionospheric dynamics, b) nightside ionospheric densities, c) nightside ionospheric temperatures, and d) ionospheric magnetic fields. IONOSPHERIC DYNANICS The early retarding potential analyzer (RPA) results /1/ from the Pioneer Venus Orbiter (PVO) which showed the presence of large horizontal day to night velocities, led to a series of attempts to model and thus establish the mechanisms responsible for these flows. The first effort in this direction was by Knudsen et al /2/ who estimated the various force terms and who found that the plasma pressure gradient is the principal force accelerating the plasma across the terminator into the antisolar direction.
