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: Central peaks of Hale Crater
THEMIS Image of the Day, January 11, 2019. Today’s VIS image shows part of the floor of Hale Crater and the elongate axis of the central peak mountains. Hale Crater is an example of an oblique impact crater. The mountain … Continue reading

THEMIS: Something odd in Noachis Terra
THEMIS Image of the Day, January 9, 2019. This VIS image shows a portion of Noachis Terra to the northeast of Argyre Planitia. In the middle of the image is an unnamed crater that is not even close to being … Continue reading

THEMIS: Not quite round
THEMIS Image of the Day, July 23, 2018. This VIS image shows an unnamed crater in Noachis Terra. The crater is relatively young, with several different structures on the floor and rim still visible. The inner rim of the crater … Continue reading

HiRISE: A triple crater
This image (making a stereo pair with ESP_041350_1455) shows an elongated depression from three merged craters. The raised rims and ejecta indicate that these are impact craters rather than collapse or volcanic landforms. The pattern made by the ejecta and … Continue reading

HiRISE: Dragonfly-shaped crater
The broader scene for this image is the fluidized ejecta from Bakhuysen Crater to the southwest, but there’s something very interesting going on here on a much smaller scale. A small impact crater, about 25 meters in diameter, with a … Continue reading

HiRISE: On the shapes of impact craters
The shape of a crater can depend on factors including the angle of impact and the pre-impact slope and topography. This image shows a roughly 3-kilometer impact crater, formed on the sloping walls of Tithonium Chasma, part of the large … Continue reading
