HiRISE: Frosty gullies on the northern plains

Posted on July 16, 2015 by rburnham

Seasonal frost commonly forms at middle and high latitudes on Mars, much like winter snow on Earth. However, on Mars most frost is carbon dioxide (dry ice) rather than water ice. This frost appears to cause surface activity, including flows … Continue reading →

THEMIS: Candor Chasma — false color

Posted on June 8, 2015 by rburnham

THEMIS Image of the Day, June 8, 2015. The THEMIS VIS camera contains 5 filters. The data from different filters can be combined in multiple ways to create a false color image. These false color images may reveal subtle variations … Continue reading →

HiRISE: Fresh crater near Sirenum Fossae

Posted on June 8, 2015 by rburnham

This impact crater appears relatively recent as it has a sharp rim and well-preserved ejecta. The steep inner slopes are carved by gullies and include possible recurring slope lineae on the equator-facing slopes. Fresh craters often have steep, active slopes, … Continue reading →

HiRISE: Alluvial fans in Mojave Crater

Posted on May 22, 2015 by rburnham

Stereo data from an anaglyph (or 3D) image shows that the landscape in this observation is pervasively eroded, right up to the tops of the ridges, with channels extending down into depositional fans much like alluvial fans in the Mojave … Continue reading →

HiRISE: Warm-season flows in cold-season ravines

Posted on May 13, 2015 by rburnham

Ravines (or very large gullies) are actively forming on Mars during the coldest times of year, when carbon dioxide frost aids mass wasting. However, some of these ravines also show activity in the warmest time of year, in the form … Continue reading →
