The uncanny in Howard Hawks’s The Big Sleep Christophe GELLY Dealing with The Big Sleep as a work fraught with uncanny representations now seems self-evident, after so many critics—whether in the field of literary or film studies— unsuccessfully strove to recapture the true development of the criminal plot unravelled by Marlowe: one piece still insists on being missing and points to the unsatisfactory closure of the text as well as the movie. It may be the mystery around Owen Taylor’s death, a minor character (but are there really minor characters in the detective genre, before the final solution supposedly sets up the characters’ roles for good?), or the main criminal protagonist in the movie, Eddie Mars, whose guilt is problematic in the plot. In other words, the disturbing, uncanny quality in the novel and the movie stems from this problematic closure and from the mystery on who did what precisely in the story—hence this quality derives from a debunking of the genre as self-contained and purely self-explanatory, an “ideal” of the text by which the text fails to abide.

    ICEBREAKER: A LUNAR SOUTH POLE EXPLORING ROBOT CMU-RI-TR-97-22 Matthew C. Deans Alex D. Foessel Gregory A. Fries Diana LaBelle N. Keith Lay Stewart Moorehead Ben Shamah Kimberly J. Shillcutt Professor: Dr. William Whittaker The Robotics Institute Carnegie Mellon University Pittsburgh PA 15213 Spring 1996-97 Executive Summary Icebreaker: A Lunar South Pole Exploring Robot Due to the low angles of sunlight at the lunar poles, craters and other depressions in the polar regions can contain areas which are in permanent darkness and are at cryogenic temperatures. Many scientists have theorized that these cold traps could contain large quantities of frozen volatiles such as water and carbon dioxide which have been deposited over billions of years by comets, meteors and solar wind. Recent bistatic radar data from the Clementine mission has yielded results consistent with water ice at the South Pole of the Moon however Earth based observations from the Arecibo Radar Observatory indicate that ice may not exist. Due to the controversy surrounding orbital and Earth based observations, the only way to definitively answer the question of whether ice exists on the Lunar South Pole is in situ analysis. The discovery of water ice and other volatiles on the Moon has many important benefits. First, this would provide a source of rocket fuel which could be used to power rockets to Earth, Mars or beyond, avoiding the high cost of Earth based launches. Secondly, water and carbon dioxide along with nitrogen from ammonia form the essential elements for life and could be used to help support human colonies on the Moon.

    To appear in Cometary Nuc/ei in Space and Time, ed. M. F. A’Hearn, ASP Conference Series, 1999 Comet Missions in NASA’s New Millennium Program Paul R. Weissman Earth and Space Sciences Division, Jet Propulsion Laboratory, Mail stop 183-601, 4800 Oak Grove Drive, Pasadena, CA 91109 USA Abstract. NASA’s New Millennium Program (NMP) is designed to develop, test, and flight validate new, advanced technologies for plane- tary and Earth exploration missions, using a series of low cost space- craft. Such new technologies include solar-electric propulsion, inflatable- rigidizable structures, autonomous navigation and maneuvers, advanced avionics with low mass and low power requirements, and advanced sensors and concepts for science instruments. Two of NMP’s currently identified interplanetary missions include encounters with comets. The first is the Deep Space 1 mission which was launched in October, 1998 and which will fly by asteroid 1992 KD in 1999 and possibly comet Wilson-Harrington and/or comet Borrelly in 2001. The second NMP comet mission is Deep Space 4/Champollion which will be launched in April, 2003 and which will rendezvous with, orbit and land on periodic comet Tempel 1 in 2006. DS-4/Champollion is a joint project with CNES, the French space agency. 1. Introduction The advent of small, low-cost space missions has brought with it a need for new, advanced technologies which can enable productive missions with the smaller launch vehicles and payloads employed. In order to promote such technologies, NASA has created the New Millennium Program (NMP), administered by the Jet Propulsion Laboratory. New Millennium provides flight opportunities to validate new spacecraft, instrument, and operations technologies through a series of low cost missions.

    Appendix I Lunar and Martian Nomenclature

    APPENDIX I LUNAR AND MARTIAN NOMENCLATURE LUNAR AND MARTIAN NOMENCLATURE A large number of names of craters and other features on the Moon and Mars, were accepted by the IAU General Assemblies X (Moscow, 1958), XI (Berkeley, 1961), XII (Hamburg, 1964), XIV (Brighton, 1970), and XV (Sydney, 1973). The names were suggested by the appropriate IAU Commissions (16 and 17). In particular the Lunar names accepted at the XIVth and XVth General Assemblies were recommended by the 'Working Group on Lunar Nomenclature' under the Chairmanship of Dr D. H. Menzel. The Martian names were suggested by the 'Working Group on Martian Nomenclature' under the Chairmanship of Dr G. de Vaucouleurs. At the XVth General Assembly a new 'Working Group on Planetary System Nomenclature' was formed (Chairman: Dr P. M. Millman) comprising various Task Groups, one for each particular subject. For further references see: [AU Trans. X, 259-263, 1960; XIB, 236-238, 1962; Xlffi, 203-204, 1966; xnffi, 99-105, 1968; XIVB, 63, 129, 139, 1971; Space Sci. Rev. 12, 136-186, 1971.

    Frontispiece Advanced Lunar Base In this panorama of an advanced lunar base, the main habitation modules in the background to the right are shown being covered by lunar soil for radiation protection. The modules on the far right are reactors in which lunar soil is being processed to provide oxygen. Each reactor is heated by a solar mirror. The vehicle near them is collecting liquid oxygen from the reactor complex and will transport it to the launch pad in the background, where a tanker is just lifting off. The mining pits are shown just behind the foreground figure on the left. The geologists in the foreground are looking for richer ores to mine.

See pages 160-161. Background: a portion of the meandering canyons of the Nanedi Valles system viewed by Mars Global Surveyor. The valley is about 2.5 km wide; the scene covers 9.8 km by 27.9 km centred on 5.1°N/48.26°W. The valley floor at top right exhibits a 200 m-wide channel covered by dunes and debris. This channel suggests that the valley might have been carved by water flowing through the system over a long period, in a manner similar to rivers on Earth.
