The barchan dunes are a field of fascinating dunes.
There are dunes in the North Pole of Mars.
The HiRISE camera takes pictures that show features as small as a desk from space.
When the image was taken, MRO was almost 200 kilometers above the surface and less than a mile across.
Barchan dunes are found on both Earth and Mars.
The dunes are important to scientists because they can tell them about the environment in which they formed and the direction of the winds.
There are sandy areas where winds blow in a single direction. The sand dune is shaped like a crescent. Sand is blown into crests and slopes when the barchan dunes end inhorns.
This is a shape that looks similar to the Star Trek logo.
The dunes shown above aren't shaped in the traditional crescent, chevron shape, so the winds must swirl in different directions.
The red-green-blue filter on the camera was used to take the picture.
One of the highest resolution cameras currently in space is the HiRISE camera, which has a telescopic lens.
Scientists can use these high-resolution images to distinguish 1-meter-size objects on Mars and to study the surface structure in a much more comprehensive manner than other Mars missions.
In order to get information on the minerals present, HiRISE makes observations at the near-IR wavelength.
planetary scientists can track changes over time because MRO has been in Mars for six years.
The team wants to be able to see seasonal changes in this region over time.
