HiRISE: Blocks and troughs
Blocks and troughs. This region in Margaritifer Chaos is located in a system of finger-like rifts and cracked surface stretching south from what appear to be three impact craters. The interaction/relation between these valleys and their neighboring craters could be … Continue reading

THEMIS: Elysium Planitia in false color
THEMIS Image of the Day, March 26, 2019. Today’s false-color VIS image is located in Elysium Planitia. The linear depressions at the top of the image are created by tectonic faults, where the center block of material has dropped downward … Continue reading

THEMIS: Claritas Fossae channel
THEMIS Image of the Day, March 14, 2019. Today’s VIS image shows a section of an unnamed channel. This channel starts in Claritas Fossae and empties down into Icaria Planum. The linear features that parallel the sides of the image … Continue reading

THEMIS: Volcanic plains east of Olympus Mons
THEMIS Image of the Day, February 22, 2019. This VIS false-color image shows a small part of the extensive volcanic plains located east of the giant volcano Olympus Mons. While the colors are generally soft and subtle, they indicate real … Continue reading

THEMIS: Out of round
THEMIS Image of the Day, January 21, 2018. This VIS image shows a group of craters in Terra Sirenum. The apparent youngest one is the center crater with the scalloped rim. Subsurface tectonic features like faults can interfere with crater … Continue reading

THEMIS: Tectonics meets volcanism in Claritas Fossae
THEMIS Image of the Day, January 10, 2019. This VIS image shows part of Claritas Fossae. The linear features (fossae) are faults. This region of Mars had very active tectonism and volcanism, resulting in the huge volcanos like Arsia Mons … Continue reading

THEMIS: Tectonic scars in Sirenum Fossae
THEMIS Image of the Day, January 4, 2019. The linear features in this VIS image are graben called Sirenum Fossae. Graben are formed when blocks of material move downward between parallel faults. The faults were created by tectonic stresses in … Continue reading
