HiPOD 14 Jan 2019: The Source of Dunes in Chasma Boreale— HiRISE (NASA) (@HiRISE) January 14, 2019
These dunes, which are near the head of the largest trough in the North Polar cap, were formed by strong winds blowing down the canyon toward its mouth.

HiPOD 21 Jan 2019: Contours— HiRISE (NASA) (@HiRISE) January 21, 2019
The objective of this observation is to search for layers in the northern ice cap. And also to marvel at the contours that were centuries in the making.

The terrain here looks like it took many serious lashings. Could any of these impacts be secondary craters?

This observation is within an large impact crater, located north of Her Desher Vallis. The region itself is south of the Valles Marineris canyon system.

A very interesting-looking 5-kilometer crater located in Ascraeus Mons, a large shield volcano located in the Tharsis region of the planet Mars.

We’ve been studying #Mars for more than 15 years with Mars Express. Now ExoMars @ESA_TGO is sniffing for gases and sending images like this: an ancient river delta that once carried liquid water across the planet’s surface! #ScienceAtESA— ESA (@esa) February 4, 2019

These pockmarked plains outside of a larger impact crater show some very nice (enhanced) colors.
