THEMIS: Cyane Fossae on Alba Mons
THEMIS Image of the Day, June 21, 2019. This VIS image shows lava flows from Alba Mons, and a tectonic graben called Cyane Fossae. It is thought that the linear depressions that surround Alba Mons were created by a huge … Continue reading

THEMIS: Summit caldera of Arsia Mons
THEMIS Image of the Day, June 10, 2019. Today’s VIS image shows part of the summit caldera of Arsia Mons. Arsia Mons is the southernmost of the three large Tharsis volcanoes. Extensive lava plains originated from eruptions of this volcano. … Continue reading

HiRISE: Resistant lava and erosion
This image demonstrates the curious phenomenon called “topographic inversion.” The southern half of the picture is covered by a well-preserved lava flow. The flow stops just at the brink of descending a steep slope. Lava isn’t afraid of falling, so … Continue reading
