Prospero 8/4/2008 | 0 (0) | 22 | 0 | 0 | English

Blewett & Hawke, Institute of Geophysics & Planetology, University of Hawai'i; Optical maturity (OMAT) images are an important a tool for investigating features on the lunar surface whose origins are related to maturity and albedo. An interesting case is "Stuart's crater", whose formation may have been photographed by an amateur astronomer half a century ago. Buratti and Johnson used a Clementine ratio image to identify a particular feature as a candidate impact for the flash photographed by L. H. Stuart in 1953. Other's have cast doubt on the interpretation.  ... more>>

Charles J. Byrne, Image Again, Middletown, New Jersey: It is difficult to grasp a good mental image of the major features of the moon in terms of their global distribution and relationships. There is no equivalent of the organization of terrestrial geography in terms of continents and oceans that are so useful in establishing a mental and visual image of Earth. This paper proposes a set of focal points and associated regions for the organization of images of the moon  ... more>>

Unusual Radar Backscatter Properties Along the Northern Rim of Imbrium Basin

Prospero 8/12/2008 | 0 (0) | 12 | 0 | 0 | English

Thompson, Campbell, JPL, Pasadena, National Air and Space Museum, Smithsonian Institution, Washington. In general, radar backscatter from the lunar terrae is 2-4 times that of the maria. One exception to this is the terra terrain along the northern rim of Imbrium Basin. The highlands that surround Sinus Iridum and crater Plato have long-wavelength (70-cm) radar backscatter that is comparable to or lower than that from the adjacent maria. We are studying new 70-cm radar images and earlier multispectral data to better constrain the regional geology  ... more>>

Samsung, Sony Offer Best Value in Blu-Ray Players (Review by Grace Aquino)

slimminds 6/11/2008 | 0 (0) | 110 | 0 | 0 | English

Samsung's BD-P1400 and Sony's BDP-S500 showed a slight edge over the other devices. Images looked extra sharp on my plasma and colors were truly vivid. Even standard DVDs looked better because the Blu-ray devices I evaluated can perform a technique called upconversion which takes standard definition content and converts it to high definition by adding pixels on the screen. Both of my DVD flicks looked great on the HDTV, although movies on Blu-ray discs appeared even richer.  ... more>>

VERIFICATION OF QUALITY AND COMPATIBILITY FOR THE NEWLY CALIBRATED CLEMENTINE NIR DATA SET

Prospero 8/4/2008 | 0 (0) | 32 | 0 | 0 | English

Cahill, Lucey, Gillis & Steutel, Hawai'i Institute of Geophysics and Planetology, University of Hawai'i at Manoa; In February 1994, the Clementine spacecraft began orbiting the Moon with a suite of instrumentation that generated millions of images of the lunar surface. Over the past decade, calibration of the NIR data set has been troublesome due to largely varying dark frame signals with time and orbit and uncertainties on gain and offset values. automated. Recently, the USGS, Flagstaff released these data with a near final calibration.  ... more>>

GROUND-BASED OBSERVATION OF LUNAR SURFACE BY LUNAR VIS/NIR SPECTRAL IMAGER

Saito, Takata, Matsushita, Chishima1, Ikeda, Hirao & Iijima, Miyagi University of Education Sendai, Japan, Yamanashi Science Center, Genesia co., Tohoku University, Dept. Mineralogy, Petrology, and Economic Geology, ISAS/JAXA Ground-based Lunar VIS/NIR Spectral Imager is developed in order to understand mineral abundance of the lunar surface and resulting spectral analysis of the lunar surface. Three dimensional spectral and spatial images of the nearside of the moon can be obtained. Preliminary imaging and data reduction have been conducted in the area of mare Serenitatis and Tranquillitatis. Global imaging of the entire nearside of the moon is planned to be conducted. Mineral abundance of the lunar mare materials is essential in order to clarify the lunar resurfacing process, in particular, the relationship between the distribution of volcanic emplacements and origins of the magma. Spectral analysis of lunar surface acquired by remote sensing is important to understand the global distribution of mineral abundance. Clementine UV/VIS images provided a catalog of narrow-band spectral images of the entire lunar surface and global maps of Fe and Ti contents and mineral abundance are created. However, the result indicates a very low abundance of olivine in South Pole Aitken basin and it is controversial to the previous results. Spectral catalog of ground based spectral observations is provided. However, their observation is a point by point, and not covered the entire surface. In order to obtain mineral maps of the moon, we have developed a ground based Lunar Spectral Imager  ... more>>

Robinson, Eliason, Hiesinger, Jolliff, McEwen, Malin, Ravine, Roberts, Thomas & Turtle Northwestern Univ., Center for Planetary Sciences, Evanston - LPL, Univ. of Arizona, Brown Univ., Washington Univ., Malin Space Science Systems, Adler Planetarium, Cornell Univ. The Lunar Reconnaissance Orbiter Camera (LROC) is designed to address two of the prime LRO measurement requirements. 1) Assess meter and smaller-scale features to facilitate safety analysis for potential lunar landing sites near polar resources, and elsewhere on the Moon. 2) Acquire multi-temporal synoptic imaging of the poles every orbit to characterize the polar illumination environment (100 m scale), identifying regions of permanent shadow and permanent or near-permanent illumination over a full lunar year. The LROC consists of two narrowangle camera components (NACs) to provide 0.5-m scale panchromatic images over a 5-km swath, a wide-angle camera component (WAC) to provide images at a scale of 100 m in seven color bands over a 100-km swath, and a common Sequence and Compressor System (SCS).  ... more>>

OPTICAL RESPONSE AND SURFACE PHYSICAL PROPERTIES OF THE LUNAR REGOLITH AT REINER GAMMA FORMATION FROM CLEMENTINE ORBITAL PHOTOMETRY: DERIVATION OF THE HAPKE PARAMETERS AT LOCAL SCALE

Prospero 8/5/2008 | 0 (0) | 26 | 0 | 0 | English

Pinet, Cord, Chevrel & Daydou, CNRS/ Toulouse University, Midi-Pyrenees Observatory, Toulouse, France; In the last decade, integrated telescopic and spaceborne photometric observation of planetary regolith has progressively evolved from wholedisk toward disk-resolved measurements at regional scales, and more recently toward local scale studies. Intriguing areas named swirls have been identified for long as they display regional and local anomalous photometric behaviors. In particular, previous investigations conducted from UVVIS telescopic and Clementine spectral images have established the peculiar optical behavior of the lunar regolith at Reiner Gamma Formation.  ... more>>

Becker, Weller, Gaddis, Soltesz, Cook, Bennett, Galuszka, Redding & Richie, Astrogeology Team, U.S. Geological Survey, Flagstaff; Lunar Orbiter (LO) images were photographic products acquired on the spacecraft in five missions (LO-I through -V) while in orbit over the lunar surface in the late 1960’s. LO data were transmitted to Earth as analog data after onboard scanning of the original film into a series of strips. We report on our ongoing effort to digitize, archive, and process a subset of these LO photographic data. The results of this work will be a global, cartographically accurate, cosmetically enhanced, digital photographic mosaic of the Moon. This LO mosaic will be coregistered to the Clementine 750-nm global mosaic.  ... more>>

RADAR PROPERTIES OF LUNAR BASIN DEPOSITS

Campbell, Campbell, Hawke & Lucey, Center for Earth and Planetary Studies, Smithsonian Institution, Washington, Cornell University, Ithaca, University of Hawaii; Basin-forming impacts have sculpted much of the lunar highland terrain, and their overlapping distal ejecta deposits form the “megaregolith.” Variations in surface morphology have been used to identify likely contacts between ejecta from various basins, but there has been little opportunity to study differences in physical properties due to age, distance from basin rim, and perhaps target composition. We address this issue through new high-resolution 70-cm radar images, which penetrate to depths of 5 m or more in the highland regolith, thermal infrared eclipse maps, and multi-spectral data  ... more>>

MARE VOLCANISM ON THE MOON INFERRED FROM CLEMENTINE UVVIS DATA

Prospero 8/12/2008 | 0 (0) | 23 | 0 | 0 | English

Kodama1 and Yamaguchi, Japan Aerospace Exploration Agency (JAXA), Ibaraki, Japan, Department of Earth and Planetary Sciences, Nagoya University, Furo-cho, Nagoya, Japan. The compositional distribution and the stratigraphy of the mare basalts are important to our understanding of the composition of the lunar interior and its thermal evolution. Previous works using the Earth-based telescopes or remote sensing data revealed a large variation in the composition of mare basalts, and suggested that the basin-scale mare volcanism evolved independently of neighboring regions. It is therefore necessary to know the chemical properties of mare basalts, together with their detailed distribution and stratigraphy in each region, and to understand how the mare volcanism evolved compositionally and spatially in a basin. For these purpose, we have mapped the mare basalts on the nearside of the Moon using the Clementine UVVIS multi-spectral images, and construct their stratigraphy. This abstract presents the result of Oceanus Procellarum and Mare Imbrium, and discusses the temporal and spatial variations of the mare volcanism of this area and the eastern nearside region  ... more>>
