HiRISE: Hephaestus Fossae pits
Hephaestus Fossae pits. The Hephaestus Fossae are a system of troughs and channels that are about 604 kilometers in length. The fossae have been tentatively identified as outflow channels, but their origin and evolution remain ambiguous. HiRISE Picture of the … Continue reading

THEMIS: Faulting and collapse in Sirenum Fossae
THEMIS Image of the Day, December 19, 2018. The linear depressions in this VIS image are part of Sirenum Fossae. These depressions are called graben, which form by the down drop of material between two parallel faults. The faults are … Continue reading

THEMIS: Pit chains and craters on Ascraeus Mons
THEMIS Image of the Day, November 7, 2018. The linear features in this VIS image are located on part of the large flow feature on the southern flank of Ascraeus Mons. The features most likely formed by collapse of the … 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: Chains of pit craters near summit of Arsia Mons volcano
THEMIS Image of the Day, January 4, 2018. The three large aligned Tharsis volcanoes are Arsia Mons, Pavonis Mons and Ascraeus Mons (from south to north). There are collapse features on all three volcanoes, on the southwestern and northeastern flanks. … Continue reading

THEMIS: Pits at caldera’s edge
THEMIS Image of the Day, January 3, 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
