  • The Tricky Business of Identifying Rocks on Mars
    PSRD: Using TES to interpret the composition of the Martian surface http://www.psrd.hawaii.edu/May02/MarsTES.html posted May 22, 2002 The Tricky Business of Identifying Rocks on Mars --- A new analysis of thermal emission spectra suggests a new interpretation for the composition of the Martian surface. Written by G. Jeffrey Taylor Hawai'i Institute of Geophysics and Planetology The Mars Global Surveyor mission carries a remote-sensing gizmo called the Thermal Emission Spectrometer (TES). TES detects heat waves flowing from the surface of the Red Planet. The TES team, led by Phil Christensen (Arizona State University), identified two large regions on Mars that have distinctive spectral properties. Using mathematical mixing calculations based on the thermal emission spectra of numerous materials, the TES team reported in papers led by Josh Bandfield and Victoria Hamilton that the two regions had mineral abundances similar to basalt (Surface Type 1) and andesite (Surface Type 2), two common volcanic rock types on Earth. Andesite has more silicon than does basalt, giving rise to a distinctive mineralogy. Scientists had mixed reactions to the possibility of andesite on Mars, greeting the news with fascination, consternation, or skepticism. One question raised is how uniquely the spectra of Surface Type 2 matches andesite. Michael Wyatt and Harry Y. McSween (University of Tennessee) have taken another look at the TES spectra by using a larger collection of aqueous alteration (weathering) products in the spectral mixing calculations. They show that weathered basalt also matches the spectral properties of Surface Type 2. Wyatt and McSween also note that Type 2 regions are generally confined to a large, low region that is the site of a purported Martian ocean that sloshed around billions of years ago.

Clay minerals, found in exposures of Noachian crust across the globe, preserve widespread evidence for early weathering, hydrothermal, and diagenetic aqueous environments. Noachian and Hesperian sediments include paleolake deposits with clays, carbonates, sulfates, and chlorides that are more localized in extent.

OTES is a Fourier Transform spectrometer covering the spectral range 5.71– 100 µm (1750–100 cm–1) with a spectral sample interval of 8.66 cm–1 and a 6.5-mrad field of view. The OTES telescope is a 15.2-cm diameter Cassegrain telescope that feeds a flat-plate Michelson moving mirror mounted on a linear voice-coil motor assembly. A single uncooled deuterated L-alanine doped triglycine sulfate (DLATGS) pyroelectric detector is used to sample the interferogram every two seconds. Redundant ~0.855 µm laser diodes are used in a metrology interferometer to provide precise moving mirror control and IR sampling at 772 Hz. The beamsplitter is a 38-mm diameter, 1-mm thick chemical vapor deposited diamond with an antireflection microstructure to minimize surface reflection.

  • Gray Iron Oxide in Meridiani, Mars
    PSRD: Gray hematite deposit in Terra Meridiani, Mars : http://www.psrd.hawaii.edu/Mar03/Meridiani.html posted March 13, 2003 Gray Iron Oxide in Meridiani, Mars --- A deposit of gray hematite in Terra Meridiani may suggest that water once circulated through the rock layers in this region of Mars. Written by Linda M.V. Martel Hawai'i Institute of Geophysics and Planetology In our continuing coverage of the exploration of Mars and NASA's strategy of "follow the water," PSRD highlights recent research of the hematite deposit in Terra Meridiani. The iron oxide mineral called hematite (Fe2O3) forms on Earth in several ways, most involving water. For this reason, the announcement in 2000 of the discovery of crystalline gray hematite near the Martian equator was, in a word, a watershed for planetary geologists and astrobiologists interested in unraveling the history of water and climate on Mars. Detection of the hematite in Terra Meridiani is one of the key discoveries of the Thermal Emission Spectrometer (TES) instrument on the Mars Global Surveyor (MGS) mission. Using TES spectral data in combination with image and topographic data, Brian Hynek, Raymond Arvidson, and Roger Phillips (Earth and Planetary Sciences and McDonnell Center for the Space Sciences at Washington University in St. Louis) recently made detailed regional analyses of Terra Meridiani to better understand the origin and significance of the hematite in the Martian environment. Using Earth as a guide to hematite formation, researchers think the hematite could have formed on Mars by thermal oxidation of iron-rich volcanic eruptive products during eruption or it could have formed by chemical precipitation when iron-rich water circulated through the preexisting layers of volcanic material (ash).
