On Mars that is.

This is from the Mars Reconnaissance Orbiter or MRO.  Fantastic observation.  Imagine this landslide unfolding; the gravity on Mars is just a bit less than 38 percent of what it is here on Earth so it probably seem to be happening in slow motion.   Or would it?  Lower gravity means that the perception of time would change as compared to Earth too so then what?  WHERE you are doing the observation from would make a difference I think.  Putting a pencil to that problem would be a good rainy day project

Here’s the NASA caption:

This image NASA’s Mars Reconnaissance Orbiter (MRO) finally completes a stereo pair with another observation acquired in 2007. It shows a fresh (well-preserved) landslide scarp and rocky deposit off the edge of a streamlined mesa in Simud Valles, a giant outflow channel carved by ancient floods.

The stereo images can be used to measure the topography, which in turn constrains models for the strength of the mesa’s bedrock. Do look at the stereo anaglyph.

This is a stereo pair with PSP_005701_1920.

The map is projected here at a scale of 25 centimeters (9.8 inches) per pixel. [The original image scale is 31.5 centimeters (12.4 inches) per pixel (with 1 x 1 binning); objects on the order of 94 centimeters (37 inches) across are resolved.] North is up.

NASA’s Jet Propulsion Laboratory, a division of Caltech in Pasadena, California, manages the Mars Reconnaissance Orbiter Project for NASA’s Science Mission Directorate, Washington.
