HiRISE: Formations in context (Or, what is it?)
Some HiRISE images show strange-looking formations. Sometimes it helps to look at Context Camera images to understand the circumstances of a scene—like this cutout from CTX 033783_1509—which here shows an impact crater with a central peak, and a collapse depression … Continue reading

THEMIS: Hale Crater’s central ridge
THEMIS Image of the Day, May 9,. 2017. Rather than a central peak, Hale Crater contains a complex ridge of peaks. This VIS image shows a portion of the ridge. More THEMIS Images of the Day by geological topic. … Continue reading

HiRISE: Better preserved on Mars than on Earth
In many ways, Mars bears remarkable similarities to Earth, but in some ways it is drastically different. Scientists often use Earth as an example, or analog, to help us to understand the geologic history of the Red Planet. As we … Continue reading

HiRISE: 9-km impact crater and its central peak
This image reveals an impact crater, nine kilometers in diameter, with a central peak. Impact craters of various sizes and ages can be found across the Martian surface. Each impact crater on Mars possesses a unique origin and composition, which … Continue reading

THEMIS: Rugged central peaks in Hale Crater
THEMIS Image of the Day, January 19, 2017. Today’s false color image shows part of the interior of Hale Crater. The THEMIS VIS camera contains 5 filters. The data from different filters can be combined in multiple ways to create … Continue reading

HiRISE: Raised bedrock in Terra Cimmeria
Large impact craters have central hills or mountains, because the tremendous shock waves from the impact first compresses the ground, then causes a rebound when it becomes uncompressed. This effectively raises bedrock that was once deeply buried to the surface. … Continue reading

HiRISE: Colorful bedrock in crater’s central uplift
Large impact craters rebound from the initial shock, raising deep bedrock to the surface in the central uplift of the crater. Often this bedrock has greater compositional diversity than the surface layers, because they are from greater depths, older, jumbled, … Continue reading
