Exploration of Victoria Crater by the Mars Rover Opportunity
(American Association for the Advancement of Science, 2009)
The Mars rover Opportunity has explored Victoria crater, a ~750-meter eroded impact crater formed in sulfate-rich sedimentary rocks. Impact-related stratigraphy is preserved in the crater walls, and meteoritic debris is ...
Surface Processes Recorded by Rocks and Soils on Meridiani Planum, Mars: Microscopic Imager Observations During Opportunity's First Three Extended Missions
(American Geophysical Union, 2008)
The Microscopic Imager (MI) on the Mars Exploration Rover Opportunity has returned images of Mars with higher resolution than any previous camera system, allowing detailed petrographic and sedimentological studies of the ...
Hematite Spherules at Meridiani: Results from MI, Mini-TES, and Pancam
(American Geophysical Union, 2008)
We report on observations of hematite-bearing spherules at Meridiani Planum made using the Microscopic Imager (MI), Mini-Thermal Emission Spectrometer (Mini-TES), and Panoramic Camera (Pancam) instruments on the Mars ...
Visible and Near-Infrared Multispectral Analysis of Rocks at Meridiani Planum, Mars, by the Mars Exploration Rover Opportunity
(American Geophysical Union, 2007)
[1] Multispectral measurements in the visible and near infrared of rocks at Meridiani Planum by the Mars Exploration Rover Opportunity's Pancam are described. The Pancam multispectral data show that the outcrops of the ...
In Situ Evidence for an Ancient Aqueous Environment at Meridiani Planum, Mars
(American Association for the Advancement of Science, 2004)
Sedimentary rocks at Eagle crater in Meridiani Planum are composed of fine-grained siliciclastic materials derived from weathering of basaltic rocks, sulfate minerals (including magnesium sulfate and jarosite) that constitute ...
Sedimentary Textures Formed By Aqueous Processes, Erebus Crater, Meridiani Planum, Mars
(Geological Society of America, 2006)
New observations at Erebus crater (Olympia outcrop) by the Mars Exploration Rover <i>Opportunity</i> between sols 671 and 735 (a sol is a martian day) indicate that a diverse suite of primary and penecontemporaneous ...
Veneers, Rinds, and Fracture Fills: Relatively Late Alteration of Sedimentary Rocks at Meridiani Planum, Mars
(American Geophysical Union, 2008)
Veneers and thicker rinds that coat outcrop surfaces and partially cemented fracture fills formed perpendicular to bedding document relatively late stage alteration of ancient sedimentary rocks at Meridiani Planum, Mars. ...
