Tuesday, March 21, 2017 [T336] POSTER SESSION I: OPPORTUNITY ROVER OBSERVATIONS 6:00 p.m. Town Center Exhibit Area

Fraeman A. A. Golombek M. P. Lamb M. P. Palucis M. C. Dickson J. L. et al. POSTER LOCATION #529 Opportunity Observations of Grooves in Endeavour Crater’s Rim [#2196] We present Opportunity’s observations of grooves in Endeavour Crater’s rim, discuss formation hypotheses, and consider implications for future observations.

Hughes M. N. Arvidson R. E. Grant J. A. Wilson S. A. POSTER LOCATION #530 Additional Evidence of Early Fluvial Dissection of Endeavour Crater’s Rim [#1483] Comparing Endeavour Crater to the younger Bopolu Crater, evidence is presented for early fluvial processes affecting Endeavour’s rim.

Crumpler L. S. Arvidson R. E. Golombek M. Jollif B. L. Mittlefehldt D. W. POSTER LOCATION #531 Rim Structure, Stratigraphy, and Aqueous Alteration Exposures Along Opportunity Rover’s Traverse of the Noachian Endeavour Crater [#2276] Mars Exploration Rover Opportunity has explored the structure, stratigraphy, and degradation state of bedrock outcrops on the Noachian Endeavour Crater rim.

Arvidson R. E. Stein N. T. O’Sullivan J. A. Catalano J. G. Guinness E. A. et al. POSTER LOCATION #532 Retrieval of Compositional Endmembers from Opportunity Rover Observations of a Scuffed Fracture Zone in Marathon Valley, Endeavour Crater Rim [#2148] Opportunity measurements of the Marathon valley rock and soil targets were used to retrieve selected endmember compositions.

Zastrow A. M. Arvidson R. E. POSTER LOCATION #533 Use of CRISM Observations to Map Changes in the Gusev Plains and Columbia Hills and Implications for a Retrospective Survey of CRISM and Spirit-Derived Mineralogy [#1482] Comparisons of CRISM scenes over the Gusev plains and Columbia Hills emphasize the region’s dynamic nature, important for its detailed mineralogical analysis.

Morris R. V. Catalano J. G. Klingelhoefer G. Schroeder C. Gellert R. et al. POSTER LOCATION #534 Acid-Sulfate Alteration at Gusev Crater and Across Mars; High-SiO2 Residues and Ferric Sulfate Precipitates [#2697] Acid-sulfate alteration at Gusev Crater on Mars produced high-SiO2 residues and ferric sulfate precipitates, and the process was widespread across the planet.
