HiRISE: Frost highlights in springtime
This image of a crater rim strikingly shows what appear to be bright white flows coming from gullies in the crater wall. However, HiRISE has been watching these gullies for some time (going all the way back to our first … Continue reading

THEMIS: Frosty dunes in Hyperboreae Undae
THEMIS Image of the Day, August 5, 2019. Several dune fields encircle the north polar cap. Hyperboreae Undae is one of them, located near Escorial Crater and Chasma Boreale. This VIS image was taken during the spring season, when the … Continue reading

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

THEMIS: Frost patches near Mangala Fossa
THEMIS Image of the Day, May 27, 2019. This false-color image shows part of Mangala Fossa – the linear depression in the bottom half of the image. The bright blue tones in this image are thought to be surface frost. … 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: 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]

HiRISE: Monitoring frost in Corozal Crater
Monitoring frost in Corozal Crater. Corozal Crater has both active gullies and recurring slope lineae. We are monitoring the evolution of seasonal frost, which is the likely trigger for gully activity. Never mind the hulking shadow at the left. Beautiful … Continue reading

HiRISE: The Case of the Lurking Frost
HiRISE and the Case of the Lurking Frost. Sheltered by these cliffs, we can see frost build up, along with lots of sedimentary rocks. This area is also a good candidate for recurring slope lineae. Beautiful Mars series. [More at … Continue reading

HiRISE: Scarp monitoring
Scarp monitoring. The “blue” in enhanced color could be seasonal frost or perhaps ground ice. We’ll be monitoring this site for one Mars year (two Earth years) to see any changes that helps us figure out what kind of ice this … Continue reading
