HiRISE: An elongated pit in Margaritifer Terra
An elongated pit in Margaritifer Terra. There is nothing more interesting than a feature that resembles a giant amoeba. Margaritifer Terra is an ancient, heavily cratered region, centered just south of the Martian equator, and covers 2600 kilometers at its … Continue reading

HiRISE: The pits of Elysium Mons
During the 2018 Mars dust storm, we obtained a clear view of the summit of the giant volcano Elysium Mons. We see the western rim and floor of the caldera, and a chain of pits (called a “catena”) extending from … 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: 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

THEMIS: Volcanic fissure in Labeatis Fossae
THEMIS Image of the Day, May 8, 2018. The feature that crosses this VIS image is a graben. Graben are formed by tectonic action, where a block of material moves downward between a pair of faults. The northern part of … Continue reading
