THEMIS: Flows on the caldera floor of Arsia Mons
THEMIS Image of the Day, January 2, 2018. This THEMIS image shows part of the caldera floor of Arsia Mons. It is not uncommon for calderas to have “flat” floors after the final explosive eruption the empties the subsurface magma … Continue reading

THEMIS: Arsia Mons’ collapse pits
THEMIS Image of the Day, January 1, 2018. This VIS image shows part of the northeastern flank of Arsia Mons at the summit caldera. In this region the summit caldera does not have a steep margin most likely due to … Continue reading

HRSC: Fracture swarms on Mars
These striking features on Mars were caused by the planet’s crust stretching apart in response to ancient volcanic activity. The fractures in the Sirenum Fossae region in the southern hemisphere were imaged by ESA’s Mars Express in March. They extend … Continue reading

Trace Gas Orbiter: Clouds over lava flows
Diffuse, water-ice clouds, a hazy sky and a light breeze. Such might have read a weather forecast for the Tharsis volcanic region on Mars on 22 November 2016, when this image was taken by the ExoMars Trace Gas Orbiter. Clouds, … Continue reading

HiRISE; Exposed bedrock, Koval’sky impact basin
This image shows partially exposed bedrock within the Koval’sky impact basin, which is on the outskirts of the extensive lava field of Daedalia Planum. Daedalia Planum is located southwest of Arsia Mons, which may be the source responsible for filling … Continue reading

THEMIS: Lava tube skylights in Daedalia Planum
THEMIS Image of the Day, May 19, 2017. Today’s VIS image show lava flows in Daedalia Planum that originated from Arsia Mons. At lower right, note the three circular “skylights” — places where the roof of an underground lava tube … Continue reading

Arsia Mons turned off its volcanic activity about 50 million years ago
New NASA research reveals that the giant Martian volcano Arsia Mons produced one new lava flow at its summit every 1 to 3 million years during the final peak of activity. The last volcanic activity there ceased about 50 million … Continue reading
THEMIS: Grazing light at sunrise on lava flows
THEMIS Image of the Day, January 26, 2017. The grazing light of sunrise, coming from the right, reveals edges and other details in lava flows of Daedalia Planum. These flows come from Arsia Mons volcano. A windstreak is visible at … Continue reading
