HiRISE: Springtime for Russell Crater
Springtime for Russell Crater. Russell Crater is another favorite of ours, not only for its beauty, but also for the information it provides us for any changes due to sublimation, when a solid state changes directly to a gaseous one. … 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: Frost-covered dunes
Frost-covered dunes. Sprinkled with hopes and dreams, no less. This is a relatively new monitoring site that seems to have heavy carbon-dioxide snowfall. HiRISE Picture of the Day archive [More at links]

HiRISE: Spring frost on a cold world
Winter on Mars comes with a blanket of carbon dioxide snow. During the spring “thaw,” this snow evaporates into the atmosphere, lingering longest in the shallow depressions such as the troughs of polygon patterned ground. Enhanced color shows the carbon … Continue reading

HiRISE: Monitoring frost in Raga Crater
Monitoring frost in Raga Crater. We’re watching frost up-slope from known new gully flows in Raga. These appear to be distinct from recurring slope lineae we’ve seen in other craters. Beautiful Mars series. [More at links]

Trace Gas Orbiter: Frosty crater on Mars
This image shows the south-facing rim of a pit crater at 68°S in the Sisyphi Planum region of Mars. It is a colour composite made from images acquired on 2 September 2018 by the Colour and Stereo Surface Imaging System, … 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: On the intricacies of carbon dioxide ice
On the intricacies of carbon dioxide ice. Measuring the mass balance of what we call the residual South Polar cap (RSPC) has important climatic implications. This image was requested to detect any vertical changes compared to earlier observations. Beautiful Mars … Continue reading
