Seasonal Flows on Warm Martian Slopes
Alfred S. McEwen,Lujendra Ojha,Colin M. Dundas,Sarah Mattson,Shane Byrne,James J. Wray,S. Cull,Scott L. Murchie,Nicolas Thomas,Virginia C. Gulick +9 more
TL;DR: Recurring slope lineae (RSL) are narrow, relatively dark markings on steep slopes; repeat images from the Mars Reconnaissance Orbiter High Resolution Imaging Science Experiment show them to appear and incrementally grow during warm seasons and fade in cold seasons.
Journal ArticleDOI
Distribution of Mid-Latitude Ground Ice on Mars from New Impact Craters
Shane Byrne,Colin M. Dundas,M. R. Kennedy,Michael T. Mellon,Alfred S. McEwen,S. Cull,Ingrid Daubar,David Shean,Kimberly D. Seelos,Scott L. Murchie,Bruce A. Cantor,Raymond E. Arvidson,Kenneth S. Edgett,A. Reufer,Nicolas Thomas,Tanya N. Harrison,L. Posiolova,Frank P. Seelos +17 more
TL;DR: Observations of ground ice exposed by recent impact craters probe the composition of the upper layers of the surface of Mars, and derive ice-table depths that are consistent with models using higher long-term average atmospheric water vapor content than present values.
Journal ArticleDOI
Recurring slope lineae in equatorial regions of Mars
Alfred S. McEwen,Colin M. Dundas,Sarah Mattson,Anthony D. Toigo,Lujendra Ojha,James J. Wray,Matthew Chojnacki,Shane Byrne,Scott L. Murchie,Nicolas Thomas +9 more
TL;DR: The recurring slope lineae are narrow, dark markings on steep slopes that appear and incrementally lengthen during warm seasons on low-albedo surfaces as discussed by the authors, and fade in cooler seasons and recur over multiple Mars years.
Journal ArticleDOI
Columbus crater and other possible groundwater-fed paleolakes of Terra Sirenum, Mars
James J. Wray,Ralph E. Milliken,Colin M. Dundas,Gregg A. Swayze,Jeffrey C. Andrews-Hanna,A. M. Baldridge,Matthew Chojnacki,Janice L. Bishop,B. L. Ehlmann,Scott L. Murchie,Roger N. Clark,Frank P. Seelos,Livio L. Tornabene,Steven W. Squyres +13 more
TL;DR: The authors in this paper investigated the morphology, thermophysical properties, mineralogy, and stratigraphy of these deposits; explore their regional context; and interpret the crater's aqueous history.
Journal ArticleDOI
A Closer Look at Water-Related Geologic Activity on Mars
Alfred S. McEwen,Candice Hansen,W. A. Delamere,Eric M. Eliason,Kenneth E. Herkenhoff,Lajos Keszthelyi,Virginia C. Gulick,R. L. Kirk,Michael T. Mellon,John A. Grant,Nicolas Thomas,Catherine M. Weitz,Steven W. Squyres,Nathan T. Bridges,Scott L. Murchie,Frank P. Seelos,Kimberly D. Seelos,Chris H. Okubo,M. P. Milazzo,Livio L. Tornabene,Windy L. Jaeger,Shane Byrne,Patrick Russell,J. L. Griffes,Sara Martínez-Alonso,Alexandra K. Davatzes,Frank C. Chuang,Bradley J. Thomson,Kathryn E. Fishbaugh,Colin M. Dundas,K. J. Kolb,Maria E. Banks,James J. Wray +32 more
TL;DR: A close look at key locations with the High-Resolution Imaging Science Experiment on board the Mars Reconnaissance Orbiter sees evidence of fluvial modification of geologically recent mid-latitude gullies and equatorial impact craters, but cannot confirm the reality of ancient oceans or water in active gullies.
