The Case of the Martian Boulder Piles


This image was initially indicated to track the motion of dune near the North Pole of Mars, however exactly what’s on the ground between the dunes is simply as fascinating!

The ground has parallel dark and light stripes from upper delegated reduce right in this location. In the dark stripes, we see stacks of stones at routine periods.

What arranged these stones into neatly-spaced stacks? In the Arctic back in the world, rocks can be arranged by a procedure called “frost heave.” With frost heave, consistently freezing and thawing of the ground can bring rocks to the surface area and arrange them into stacks, stripes, and even circles. In the world, among these temperature level cycles takes a year, however on Mars it may be linked to modifications in the world’s orbit around the Sun that take a lot longer.

The map is predicted here at a scale of 25 centimeters (9.8 inches) per pixel. [The original image scale is 32 centimeters (12.6 inches) per pixel (with 1 x 1 binning); objects on the order of 96 centimeters (37.8 inches) across are resolved.] North is up.

The University of Arizona, Tucson, runs HiRISE, which was constructed by Ball Aerospace & & Technologies Corp., Stone, Colorado. NASA’s Jet Propulsion Lab, a department of Caltech in Pasadena, California, handles the Mars Reconnaissance Orbiter Task for NASA’s Science Objective Directorate, Washington.
