Abstract Background: NASA selected the Mars Orbiter Camera (MOC) investigation in 1986 for the Mars Observer mission. The MOC consisted of three elements which shared a common package: a narrow angle camera designed to obtain images with a spatial resolution as high as 1.4 m per pixel from orbit, and two wide angle cameras (one with a red filter, the other blue) for daily global imaging to observe meteorological events, geodesy, and provide context for the narrow angle images. Following the loss of Mars Observer in August 1993, a second MOC was built from flight spare hardware and launched aboard Mars Global Surveyor (MGS) in November 1996.

  • The Eastern Outlet of Valles Marineris: a Window Into the Ancient Geologic and Hydrologic Evolution of Mars
    First Landing Site/Exploration Zone Workshop for Human Missions to the Surface of Mars (2015) 1054.pdf The Eastern Outlet of Valles Marineris: A Window into the Ancient Geologic and Hydrologic Evolution of Mars Stephen M. Clifford, David A. Kring, and Allan H. Treiman, Lunar and Planetary Institute/USRA, 3600 Bay Area Bvld., Houston, TX 77058 Over its 3,500 km length, Valles Marineris exhibits enormous range of geologic and environmental diversity. At its western end, the canyon is dominated by the tectonic complex of Noctis Labyrinthus while, in the east, it grades into an extensive region of chaos - where scoured channels and streamlined islands provide evidence of catastrophic floods that spilled into the northern plains [1-4]. In the central portion of the system, debris derived from the massive interior layered deposits of Candor, Ophir and Hebes Chasmas spills into the central trough have been identified as possible lucustrine sediments that may have been laid down in long-standing ice-covered lakes [3-6]. The potential survival and growth of Martian organisms in such an environment, or in the aquifers whose disruption gave birth to the chaotic terrain at the east end of the canyon, raises the possibility that fossil indicators of life may be present in the local sediment and rock. In other areas, 6 km-deep exposures of Hesperian and Noachian-age canyon wall stratigraphy have collapsed in massive landslides that extend many tens of kilometers across the canyon floor. Ejecta from interior craters, aeolian sediments, and possible volcanics (which appear to have emanated from structurally controlled vents along the base of the scarps), further contribute to the canyon's geologic complexity [2,3].

  • 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.

Kostama, Astronomy, Department of Physics, P.O. Box 3000, FI-90014 University of Oulu, Finland ([email protected]). Introduction: Harmakhis Vallis is one of the four [e.g., 15–17]. Usually they have been excluded from major outflow channel systems that cut the eastern Hel- the crater counts because of the uncertainty of their las rim region of Mars (Fig. 1). It is ~800 km long and origin (primary vs. secondary crater). However, small located ~450 km south of Hadriaca Patera starting craters accumulate to the surface more quickly than close to the end of another valley, Reull Vallis. Due to larger ones, and thus the high spatial resolution is nec- the close position to the volcanic features, the channels essary in dating younger surfaces or small units where are suggested to have been formed by the mobilization there are only few large craters.

  • Hesiod Theogony.Pdf
    Hesiod (8th or 7th c. BC, composed in Greek) The Homeric epics, the Iliad and the Odyssey, are probably slightly earlier than Hesiod’s two surviving poems, the Works and Days and the Theogony. Yet in many ways Hesiod is the more important author for the study of Greek mythology. While Homer treats cer- tain aspects of the saga of the Trojan War, he makes no attempt at treating myth more generally. He often includes short digressions and tantalizes us with hints of a broader tra- dition, but much of this remains obscure. Hesiod, by contrast, sought in his Theogony to give a connected account of the creation of the universe. For the study of myth he is im- portant precisely because his is the oldest surviving attempt to treat systematically the mythical tradition from the first gods down to the great heroes. Also unlike the legendary Homer, Hesiod is for us an historical figure and a real per- sonality. His Works and Days contains a great deal of autobiographical information, in- cluding his birthplace (Ascra in Boiotia), where his father had come from (Cyme in Asia Minor), and the name of his brother (Perses), with whom he had a dispute that was the inspiration for composing the Works and Days. His exact date cannot be determined with precision, but there is general agreement that he lived in the 8th century or perhaps the early 7th century BC. His life, therefore, was approximately contemporaneous with the beginning of alphabetic writing in the Greek world. Although we do not know whether Hesiod himself employed this new invention in composing his poems, we can be certain that it was soon used to record and pass them on.

  • Iani Chaos As a Landing Site for the Mars Science Laboratory. T. D. Glotch1, 1Jet Propulsion Laboratory, Cali- Fornia Institute of Technology
    Iani Chaos as a landing site for the Mars Science Laboratory. T. D. Glotch1, 1Jet Propulsion Laboratory, Cali- fornia Institute of Technology. [email protected] Iani Chaos, the source region of Ares Valles, is centered at ~342°E, 2°S. The chaotic terrain is widely- believed to have formed via the removal of subsurface water or ice, resulting in flooding at the surface, and the formation of Ares Vallis. Within Iani Chaos, de- posited stratigraphically above the chaotic terrain, are smooth, low-slope, intermediate-to-light-toned depos- its that are rich in a hydrated mineral that is most likely gypsum [1] as well as hematite[2-3] (Figure 1). Crystalline hematite and sulfates have been de- tected from orbit in numerous locations, including Me- ridiani Planum [4], Aram Chaos [1,5-6], Valles Marin- eris[5], and Aureum and Iani Chaos[2-3]. The MER Opportunity rover landed at Meridiani Planum and has shown that hematite is present as spherules that erode from a light-toned sulfate-rich outcrop. The MER team’s hypothesis of an ancient dune/interdune playa environment at Meridiani Planum[7] has been chal- lenged by both volcanic[8] and impact[9] models. A Figure 1. Map of hematite abundance in Iani Chaos. Hema- rover sent to one of the other locations rich in hematite tite abundance varies from ~5-20%. Based on OMEGA and sulfates will help to resolve the current debate and data[1], the presence of sulfate roughly correlates with that increase understanding of the role of ground and sur- of hematite.
