The dry barren plains of Tyrrhena Terra
Click for full image.
In a sense today’s cool image is a replay of one I posted in March, showing the dry barren terrain in the vast rough cratered highlands of Tyrrhena Terra, located along the equator of Mars between the giant basins of Isidis and Hellas.
Today’s image on the right, cropped to post here, was taken by the high resolution camera on Mars Reconnaissance Orbiter on March 26, 2020, and shows well the barrenness of this region. The surface appears quite solid, like bedrock, rather than the squishy soft surface of the northern lowland plains. Moreover, there is a lot of dust trapped in the low areas between the ridges, forming ripples that new data suggest move slowly across the surface. If you click on the full image, you will see that this terrain is far from local, and goes on in this manner for quite a distance in all directions.
This is a dry and forbidding place, about the size of the American southwest, from Texas to California.
The overview map below provides some context of Tyrrhena Terra’s location on Mars.
