THEMIS: Sinuous features hint at ground ice
THEMIS Image of the Day, November 8, 2018. This VIS image is located in an unnamed crater in Noachis Terra. The sinuous feature near the bottom of the crater rim appears to have been caused by down slope movement of … Continue reading

HiRISE: Curving pits and ridges
This terrain is unusual for the South Polar region of Mars, with a set of curved ridges of unknown origin. Small pits are present, often concentrated on the ridges, that may have resulted from sublimation of ice. [More at link]

THEMIS: Soft-featured craters in Arcadia Planitia
THEMIS Image of the Day, October 19, 2018. This false-color VIS image shows some of the plains and craters located in Arcadia Planitia. The soft-looking features in the impact craters indicate ground ice at shallow depths below the surface. In … Continue reading

HiRISE: The walls in Milankovic Crater
The walls in Milankovic Crater. The objective of this observation is to determine the nature of depressions in the mantle on the wall of Milankovic Crater. It seems that the deeper depressions into the mantle have a straight edge along … Continue reading

THEMIS: Active dunes and ground-ice creep
THEMIS Image of the Day, August 3, 2018. This VIS image is located in the region between northern Terra Sabaea and Utopia Planitia. This unnamed crater contains a small, dark dune field. Darkness suggests the dunes are dust-free, hence probably … Continue reading
