HiRISE: Fan with inverted channels

Posted on September 6, 2018 by rburnham

This image shows inverted channels within a fan whose origin could be either fluvial (produced by the action of a stream) or alluvial (created by sedimentary deposits). If the fan is alluvial, then it formed on dry land. If the … Continue reading →

HiRISE: Pitted cones: possible methane sources?

Posted on September 5, 2018 by rburnham

This observation shows relatively bright mounds scattered throughout darker and diverse surfaces in Chryse Planitia. These mounds are hundreds of meters in size. The largest of the mounds shows a central pit, similar to the collapsed craters found at the … Continue reading →

HiRISE: Crater gullies and fractures in Acidalia Planitia

Posted on September 4, 2018 by rburnham

This image shows the gullied western slopes of an unnamed crater (about 10 kilometers wide) in Acidalia Planitia. These slopes have gone through a complicated history of gully erosion of the bedrock layers in the upper section, followed by the … Continue reading →

HiRISE: The Case of the Lurking Frost

Posted on September 4, 2018 by rburnham

HiRISE and the Case of the Lurking Frost. Sheltered by these cliffs, we can see frost build up, along with lots of sedimentary rocks. This area is also a good candidate for recurring slope lineae. Beautiful Mars series. [More at … Continue reading →

HiRISE: Relatively recent impact in Arcadia Planitia

Posted on August 30, 2018 by rburnham

Remember the great impacts of yore? Well, those days are long gone, but Mars still gets hit with impacts and we’ve catalogued hundreds of them. This particular impact formed sometime between May 2014 and October 2017. It’s only meters in … Continue reading →
