THEMIS: Pit craters on Ascraeus Mons
THEMIS Image of the Day, September 4, 2017. This image shows a collapse feature on the southeastern flank of the volcano. The circular/scalloped margin of the collapse is typical for ceiling collapse into a lava tube. However, the potential lava … Continue reading

THEMIS: Collapsed lava channel on Ascraeus Mons
THEMIS Image of the Day, September 1, 2017. This image shows part of the southern flank of Ascraeus Mons. The feature at the bottom of the image is a collapse feature. These features can be caused by several processes. The … Continue reading

THEMIS: Lava levees on Ascraeus Mons’ upper slopes
THEMIS Image of the Day, August 31, 2017. This image of the flank of Ascraeus Mons shows several individual flows where the sides are higher than the center. These are called leveed flows, as the outer margin acts as a … Continue reading

THEMIS: Flows and faults on Ascraeus Mons
THEMIS Image of the Day, August 29, 2017. Looking again at the southeastern flank of the volcano the narrow nature of the flows are visible. Given the steep sides of the volcano, flows from the summit run as narrow “rivers” … Continue reading

HiRISE: The Niagara Falls of Mars
Various researchers are often pre-occupied with the quest for flowing water on Mars. However, in this image, we see one of many examples from Mars where lava (when it was molten) behaved in a similar fashion to liquid water. In … Continue reading
