HiRISE: Linear vent and flows to the southeast of Zunil Crater
A linear vent and flows to the southeast of Zunil Crater. This is located within the Elysium quadrangle on Mars, a region with a volcanic past that for which we can still see evidence of old lava flows. Beautiful Mars … Continue reading

THEMIS: High on the east flank of Pavonis Mons
THEMIS Image of the Day, October 11, 2018. This false-color VIS image shows the eastern flank of Pavonis Mons. The darker streaks are created by wind action, and the curving lines are faults produced when the volcano “relaxed” under the … Continue reading

THEMIS: Over the summit of Pavonis Mons
THEMIS Image of the Day, September 28, 2018. Today’s VIS image crosses the flanks and summit of Pavonis Mons. Calderas are down-dropped areas which collapse when lava inside the volcano withdraws, removing its support for the heavy rock layers above. … Continue reading

HiRISE: Up above the dust clouds
When much of Mars was enshrouded by a recent massive dust storm, HiRISE captured this clear view of the surface because of the target’s unique location. Olympus Mons is the biggest volcano in the Solar System, reaching a height of … Continue reading

THEMIS: Intersecting lava channels & tectonics
THEMIS Image of the Day, August 27, 2018. The Tharsis region contains both large volcanoes and extensive lava plains. Most of the channel features in this region were formed by the flow of lava rather than the flow of water. … Continue reading
THEMIS: Lava channels on Pavonis Mons
THEMIS Image of the Day, August 24, 2018. This VIS image shows part of the southwestern flank of Pavonis Mons. The channel and nearby oval depressions are both related to the flow of lava. Narrow lava flows can create channels. … Continue reading
