Seasonal Flows on Warm Martian Slopes
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.
Sublimation of Mars's southern seasonal CO2 ice cap and the formation of spiders
[1] In this paper we define and describe morphological features that have colloquially been termed “spiders” and map their distribution in the south polar region of Mars. We show that these features
Recurring slope lineae in equatorial regions of Mars
The presence of liquid water is a requirement of habitability on a planet. Possible indicators of liquid surface water on Mars include intermittent flow-like features observed on sloping terrains.
The Polar Deposits of Mars
The tantalizing prospect of a readable record of martian climatic variations has driven decades of work toward deciphering the stratigraphy of the martian polar layered deposits and understanding the
Distribution of Mid-Latitude Ground Ice on Mars from New Impact Craters
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.
A Sublimation Model for Martian South Polar Ice Features
This work argues that a carbon dioxide ice layer about 8 meters thick is being etched away to reveal water ice underneath on Mars, consistent with thermal infrared data from the Mars Odyssey mission.
North polar stratigraphy and the paleo-erg of Mars
An accurate self-consistent way of coregistering the imaging and topographic data sets of the Mars Global Surveyor mission was developed and used to begin a stratigraphic analysis of the northern
Massive CO2 Ice Deposits Sequestered in the South Polar Layered Deposits of Mars
Shallow Radar soundings from the Mars Reconnaissance Orbiter reveal a buried deposit of carbon dioxide (CO2) ice within the south polar layered deposits of Mars with a volume of 9500 to 12,500 cubic kilometers, about 30 times that previously estimated for the south pole residual cap.
New and recent gully activity on Mars as seen by HiRISE
Fresh‐appearing gully deposits are found at tens of sites in the southern hemisphere of Mars. These deposits have latitudinal and azimuthal dependences similar to the overall preferences of
