NASA has shared images taken by Curiosity Rover on the Mars associating to the rocky surface of the Central Butte that is a part of the Gale Crater.

NASA’s Curiosity Rover is recently examining the Central Butte on the Martian surface, which is an confined hill with steep sides and a flat top. The rover shared black and white images of the rock formations of the region as it extends its investigation of the soil.

One of the images shows what looks like smog or a thick cloud blanket over the distant ledge of the Gale Crater although other pictures show the close up of the rock structure of Central Butte. “The rover is a little further up the side of the butte, and the goal is to describe the different units that we can observe,” NASA wrote on its website.

The Central Butte is also a part of the Gale Cavity, which is a repress lake with a mountain in its centre. As per an earlier study, the cavity was formed about 3.6 billion years ago on Mars when a meteor hit the planet. Scientists admit that the geological terrains of the Gale Crater have recorded the history of Mars and they are positive that the structure once held liquid water.

It has also been disclosed that Mars once had salt lakes that went through wet and dry phases similar to those on the Earth. Researchers claim that the liquid water on Mars may have become unsustainable and evaporated as the planet’s atmosphere became thinner, and the pressure at the surface became lesser.
