NASA's Curiosity rover has sent back images of the Martian sand dunes it is currently investigating. The dunes, which are two stories tall, are part of the "Bagnold Dunes" along the northwestern side of Mount Sharp inside the Gale Crater, according to Daily Mail.

The rover will also be taking samples of the sand from the dunes and have it analyzed by an on-board lab. Curiosity also took an image of an uncovered material under the sands:

The Curiosity Mars rover has already captured images of the petrified sand dunes on Mars from a distance back in August, and has sent photos of that encounter as well, as previously reported by HNGN.

These new sets of pictures, however, were taken up close on Nov. 27 using the rover's Mast Camera. Now that it is closer to the dunes, Curiosity will also have the chance to study the data it collects and help determine how much has changed in the area over time, according to Engadget.

Curiosity has been on Mars since 2012 and reached Mount Sharp in 2014, where it has been continuously investigating and trekking the mountain with the ultimate goal of examining the layers of Mount Sharp, according to NASA.
