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. -
January 2019 Cardanus & Krafft
A PUBLICATION OF THE LUNAR SECTION OF THE A.L.P.O. EDITED BY: Wayne Bailey [email protected] 17 Autumn Lane, Sewell, NJ 08080 RECENT BACK ISSUES: http://moon.scopesandscapes.com/tlo_back.html FEATURE OF THE MONTH – JANUARY 2019 CARDANUS & KRAFFT Sketch and text by Robert H. Hays, Jr. - Worth, Illinois, USA September 24, 2018 04:40-05:04 UT, 15 cm refl, 170x, seeing 7/10, transparence 6/6. I drew these craters and vicinity on the night of Sept. 23/24, 2018. The moon was about 22 hours before full. This area is in far western Oceanus Procellarum, and was favorably placed for observation that night. Cardanus is the southern one of this pair and is of moderate depth. Krafft to the north is practically identical in size, and is perhaps slightly deeper. Neither crater has a central peak. Several small craters are near and within Krafft. The crater just outside the southeast rim of Krafft is Krafft E, and Krafft C is nearby within Krafft. The small pit to the west is Krafft K, and Krafft D is between Krafft and Cardanus. Krafft C, D and E are similar sized, but K is smaller than these. A triangular-shaped swelling protrudes from the north side of Krafft. The tiny pit, even smaller than Krafft K, east of Cardanus is Cardanus E. There is a dusky area along the southwest side of Cardanus. Two short dark strips in this area may be part of the broken ring Cardanus R as shown on the. Lunar Quadrant map. -

“H.M.A.S. PERTH” 1939 -1941 From the diaries of P.O. George Hatfield Published in Sydney Australia in 2009 Publishing layout and Cover Design by George Hatfield Jnr. Printed by Springwood Printing Co. Faulconbridge NSW 2776 1 2 Foreword Of all the ships that have flown the ensign of the Royal Australian Navy, there has never been one quite like the first HMAS Perth, a cruiser of the Second World War. In her short life of just less than three years as an Australian warship she sailed all the world’s great oceans, from the icy wastes of the North Atlantic to the steamy heat of the Indian Ocean and the far blue horizons of the Pacific. She survived a hurricane in the Caribbean and months of Italian and German bombing in the Mediterranean. One bomb hit her and nearly sank her. She fought the Italians at the Battle of Matapan in March, 1941, which was the last great fleet action of the British Royal Navy, and she was present in June that year off Syria when the three Australian services - Army, RAN and RAAF - fought together for the first time. Eventually, she was sunk in a heroic battle against an overwhelming Japanese force in the Java Sea off Indonesia in 1942. Fast and powerful and modern for her times, Perth was a light cruiser of some 7,000 tonnes, with a main armament of eight 6- inch guns, and a top speed of about 34 knots. She had a crew of about 650 men, give or take, most of them young men in their twenties. -

It is of particular interest that several of the individuals were responsible for specific discoveries, observations, or inventions which considerably advanced the study and under- standing of the moon (for instance, Hadley designed the first large reflecting telescope; Beer published classic maps and explanations of the moon's surface). -

Dating the Moon: Teaching Lunar Stratigraphy and the Nature of Science the Science Teacher, February 2013
Dating the Moon: teaching lunar stratigraphy and the nature of science The Science Teacher, February 2013 As our closest celestial neighbor, the Moon is a familiar and inspiring object to investigate using a small telescope, binoculars, or even photographs or one of the many high-quality maps available online (see "On the web"). The wondrously varied surface of the Moon--filled with craters, mountains, volcanic flows, scarps, and rilles--makes the Moon an excellent context for students to explore the methods scientists use to date geologic features, while learning about scientific observation and inference. This activity includes a unique application of the law of superposition that allows students to explore the relative ages of key lunar features and their origins. Even with an unaided eye, two types of terrain seem to dominate the Moon's surface: the relatively light, very heavily cratered highlands and the dark, nearly smooth maria (Figure 1, page 36). The maria are extensive basaltic lava flows that cover about 16% of the lunar surface. As on Earth, the different types of terrain on the Moon have different ages. The relative ages of the Moon's highlands and maria can be determined by counting the number of craters per unit area superimposed on them (see sidebar at right). The older highlands have built up a larger number of impact craters than the smooth maria, which have not been exposed as long to bombarding meteoroids, asteroids, and comets (Wilhelms 1987). Craters Most craters on the Moon were caused by objects impacting the surface and explosively releasing their kinetic energy. -
1 the Terminal
2-29 Two eervice propulsion system firings were required for rendezvous. The first firing, a corrective combination maneuver, was necessary to achieve the proper phase and altitude offset so that the second firing would result in an orbit coelliptic with that of the S-IW. The two firings achieved the desired conditions for rendezvous terminal phase initiation. The terminal phase initiation maneuver was performed with an onbaard computer solution based on optical track- t ing of the s-IVB stage with the sextant. A small midcourse correction was then made, followed by braking and final closure to within 70 feet of the S-IVB. Stationkeeping was performed for approximately 20 minutes, after which a 2-foot-per-second service module reaction control system posigrade maneuver removed the spacecraft from the vicinity of the S-Iw stage. The aext 24-hour period was devoted to a sextant calibration test, a rendezvous navigation test, an attitude con- 1 trol test, and a primsry evaporator test. Tbe crew used the sextant to track the S-IVB visually to distances of as uuch as 320 miles. The service propulsion system was fired six additional times during the mission. The third firing was a 9.1-second maneuver controlled by the stabilization and control system. The maneu- ver was performed to increase the backup deorblt capability of the service module reaction con- trol system. The fourth firing was performed to evaluate the minimum-Impulse capability of the service propulsion engine. The fifth firing was performed to position the spacecraft for an op- tinum deorbit maneuver at the end of the planned orbital phase. -
