THEMIS: Labeatis Fossae in Tempe Terra
THEMIS Image of the Day, July 4, 2019. The linear depressions in this VIS image are graben called Labeatis Fossae. Graben are formed when extension between paired faults causes the material to move downward. These are part of a general … Continue reading

THEMIS: Arsia Mons faults, graben, and pit craters
THEMIS Image of the Day, July 1, 2019. Today’s VIS image is located on the lower flank of Arsia Mons. The linear features are tectonic faults. The lava flows originating from Arsia Mons are among the youngest on the surface … Continue reading

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: Crazy craters
THEMIS Image of the Day, June 19, 2019. Today’s VIS image shows two craters located on the margin of Syrtis Major Planum. The two large craters are not circular. The flatter sides are caused by the pressure wave generated by … Continue reading

THEMIS: Small graben in Acidalia Planitia
THEMIS Image of the Day, June 17, 2019. This false-color image shows a graben located in Acidalia Planitia. Graben are depressions caused by movement of material downward between paired tectonic faults. The THEMIS VIS camera contains 5 filters. The data … Continue reading

THEMIS: The graben of Ceraunius Fossae
THEMIS Image of the Day, June 12, 2019. This VIS image shows part of Cerunius Fossae. The linear depressions are fault bounded features called graben. These features form from tectonic forces that are pulling apart the surface, created space for … Continue reading

THEMIS: Faulting in Labeatis Fossae
THEMIS Image of the Day, June 7, 2019. The linear depressions in this VIS image were created by tectonic forces. The sides of the depression are faults. Paired faults will allow the block of material between them to “slide down” … Continue reading

THEMIS: Angustus Labyrinthus, the ‘Inca City’
THEMIS Image of the Day, May 1, 2019. Angustus Labyrinthus is a unique region near the south polar cap. The squares formed by intersecting ridges earned the feature the informal name of the Inca City when it was discovered in … Continue reading
