HiRISE: Everything is (well) illuminated
The south polar layered deposits are icy layers that have been deposited over millions of years, preserving a climate history of Mars. In this image the layers are well illuminated to accentuate the topography. A prior image of this location … Continue reading

THEMIS: South polar ice cap layers
THEMIS Image of the Day, March 15, 2019. This VIS image is located on the South Polar cap. The linear features are the steep side of a polar trough. At troughs the extensive layering of the ice is exposed. The … Continue reading

Lake under south polar ice cap requires local heat source
Thermal modeling suggests that active magmatism in the past few hundred thousand years could account for the presence of a large lake previously hypothesized beneath the Red Planet’s southern ice cap. Liquid water appears to be a fundamental requirement for … Continue reading

Volcanism under the south pole ice cap of Mars?
A study published last year in the journal Science suggested liquid water is present beneath the south polar ice cap of Mars. Now, a new study in the AGU journal Geophysical Research Letters argues there needs to be an underground … Continue reading

THEMIS: South polar ice cap in summer
THEMIS Image of the Day, January 24, 2019. This VIS image of the south polar cap was taken during the middle of southern hemisphere summer. The surface is free of frost and the layering that makes up the cap is … Continue reading

HiRISE: Impact near the south pole
This image shows a new impact crater that formed between July and September 2018. It’s notable because it occurred in the seasonal southern ice cap, and has apparently punched through it, creating a two-toned blast pattern. The impact hit on … Continue reading

THEMIS: South polar ice cap layers
THEMIS Image of the Day, January 7, 2019. Today’s VIS image shows a small part of the south polar cap. The layering of the cap is easy to see. The layers record the seasonal deposition of dust and ice over … Continue reading

THEMIS: Clouds over south polar cap layers
THEMIS Image of the Day, December 25, 2018. This line of clouds is located over the ice of the south polar cap. At the time of year when this VIS image was collected (southern hemisphere summer), clouds are a common … Continue reading

THEMIS: On the edge of the south polar ice cap
THEMIS Image of the Day, December 20, 2018. At the bottom of this image is the layered edge of the south polar cap. There are more layers visible between the bright polar material and the dark sand dunes at the … Continue reading
