Curiosity Reaches Massive Field of Spectacularly Rippled Active Martian Sand Dunes

After many months of painstaking driving, NASA’s Curiosity Mars rover has reached the edge of a massive field of spectacular rippled sand dunes located at the base of Mount Sharp that range up to two stories tall. And she has now begun humanity’s first up-close investigation of currently active sand dunes anywhere beyond Earth.
The dark dunes, named the “Bagnold Dunes,” skirt the northwestern flank of Mount Sharp and lie on the alien road of Curiosity’s daring trek up the lower portion of the layered Martian mountain.
Today, Dec 14, Curiosity is exploring a spectacular spot dubbed the “Namib Dune” shown in our new photo mosaic above.
Ascending and diligently exploring the sedimentary lower layers of Mount Sharp, which towers 3.4 miles (5.5 kilometers) into the Martian sky, is the primary destination and goal of the rovers long term scientific expedition on the Red Planet.
The car sized rover initially arrived a few sols ago at a spot of the rippled surface that’s been informally named “High Dune” by the team of scientists and engineers leading Curiosity’s Mars Science Laboratory (MSL) Mission on Mars.
“The science and engineering team are excited about the opportunity to study active dunes on another planet,” wrote MSL science team member Lauren Edger, Research Geologist at the USGS Astrogeology Science Center, in a mission update.
The dunes are indeed rather active and have been determined to migrate up to about one yard or —> Read More
