Mars Express: Dust storms swirl at martian north pole
ESA’s Mars Express has been keeping an eye on local and regional dust storms brewing at the north pole of the Red Planet over the last month, watching as they disperse towards the equator. Local and regional storms lasting for … Continue reading

HiRISE: Still life with an impact crater
Still life with an impact crater. Ice fill within a crater in the north polar layered deposits (NPLD) may be a site where accumulation could be observed, helping to settle a long-term problem in Mars polar science: are the NPLD … Continue reading

HiRISE: A frosted surface
This is the first of a new monitoring series to track seasonal processes. It is also a striking image with late winter angled illumination over dunes covered by carbon dioxide frost mixed with dust. Dark spots may be where sand … Continue reading

HiRISE: Dust and frost
Sand dunes in the north polar regions of Mars show light coatings of pale orange dust blown partially across the dark basaltic sand. Around the edges of the dunes, patches of seasonal dry ice remain. These patches will be gone … Continue reading

HiRISE: Frosted dunes in north polar region
A soothing way to start your Monday. These polar dunes show both carbon dioxide frost (the while colored areas) along with darker material that’s been exposed due to sublimation, and is blown by the wind to form these dark spots. … Continue reading

HiRISE: Dune erosion and streaks
Dune erosion and streaks. One of the many seasonal images we take to detect changes. In this case, we want to quantify the process of erosion driven by sublimation on the dunes. (Sublimation is the process of going directly from … Continue reading
