Martian Photos from the Mars Reconnaissance Orbiter

Mars sand dunes by NASA

“The High Resolution Imaging Science Experiment (HiRISE) camera aboard NASA’s Mars Reconnaissance Orbiter captured these sand ripples and the large dune (at center) on Feb. 9, 2009. Color has been added to make textures easier to see. This area is in Proctor Crater at 47.8 degrees south latitude and 30.7 degrees east longitude.”

The Mars Reconnaissance Orbiter was launched 15 years ago. NASA has released some fabulous photos taken by High-Resolution Imaging Science Experiment (HiRISE). Here are two of them.

EarthSky has posted an article about the HiRISE photos here.

Mars avalanche by NASA


“The High-Resolution Imaging Science Experiment (Hi-RISE) camera aboard NASA’s Mars Reconnaissance Orbiter captured this avalanche plunging down a 1,640-foot-tall (500-meter-tall) cliff on May 29, 2019. The image also reveals layers at Mars’ north pole during spring. As temperatures increase and vaporize ice, the destabilized ice blocks break loose and kick up dust.”
