Economou17 Received 14 August 2007; revised 9 November 2007; accepted 21 December 2007; published 18 April 2008. [1] Reduced weathering rates due to the lack of liquid water and significantly greater typical surface ages should result in a higher density of meteorites on the surface of Mars compared to Earth. Several meteorites were identified among the rocks investigated during Opportunity’s traverse across the sandy Meridiani plains. Heat Shield Rock is a IAB iron meteorite and has been officially recognized as ‘‘Meridiani Planum.’’ Barberton is olivine-rich and contains metallic Fe in the form of kamacite, suggesting a meteoritic origin. It is chemically most consistent with a mesosiderite silicate clast. Santa Catarina is a brecciated rock with a chemical and mineralogical composition similar to Barberton. Barberton, Santa Catarina, and cobbles adjacent to Santa Catarina may be part of a strewn field. Spirit observed two probable iron meteorites from its Winter Haven location in the Columbia Hills in Gusev Crater. -

TARZANA, CA — The U.S. Postal Service will honor tomorrow one of the most prolific authors of the early 20th century and inventor of the iconic character Tarzan with the issuance of the Edgar Rice Burroughs Forever Stamp. The stamp issuance coincides with the 100th anniversary of the publication of Burroughs’ first story, Under the Moons of Mars, and his first Tarzan story, Tarzan of the Apes, in 1912. The Edgar Rice Burroughs Forever Stamp will be dedicated tomorrow at 11:30 a.m. PT at the Tarzana Community and Cultural Center in Tarzana, CA, and will go on sale tomorrow at Post Offices nationwide, online at usps.com and by phone at 800-782-6724. Best known for inventing the legendary character Tarzan, Burroughs wrote more than 70 books, including historical fiction and several popular series of science fiction tales. “At the Postal Service, we’re proud to honor wonderful writers like Mr. Burroughs,” said Giselle Valera, vice president and managing director, Global Business. “These creative geniuses make lasting contributions to our cultural heritage, and we want more Americans to learn about them.

Hirise Camera Views the Mars Rover 'Spirit' at 'Home Plate' 26 November 2007
HiRISE Camera Views the Mars Rover 'Spirit' at 'Home Plate' 26 November 2007 Herkenhoff said. At the time, the camera was flying about 270 kilometers, or about 168 miles, over the surface. At that distance, the camera could resolve objects about 81 centimeters, or about 32 inches, across. The sun was about 56 degrees above the horizon in the winter afternoon sky. The HiRISE image of Home Plate and others are on the HiRISE Website, hirise.lpl.arizona.edu . HiRISE operations are based at The University of Arizona in Tucson. Professor Alfred S. McEwen of the Lunar and Planetary Laboratory is principal investigator for the experiment. The Mars rover "Spirit" is indicated by a circle on "Home Plate" in this new image of Gusev Crater on Mars. This The HiRISE camera is the most powerful camera detail is part of a much larger image the HiRISE camera ever to orbit another planet. It has taken thousands took on Sept. 27, 2007.

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. -
