Huge sedimentary rock found on Mars

The Mars rover Curiosity uncovered a rock made up of dozens of sediments. The research team calls this Strathdon. According to the discovery, NASA reports that the area where Curiosity is located is more geologically complex than is commonly perceived.

In recent months, Curiosity has been exploring areas where clay has been buried in the Gale Crater. Located along the slopes of the Sharp Crater, this area was once home to lakes and streams, but now remains in clay form. Investigating the area, scientists hope to give a glimpse into the distant Mars past, which could have filled Mars’ surface with water and possibly even sustained life.

During this search, Curiosity discovered a rock composed of dozens of sedimentary layers. Named Strathdon, this fragile rock layer takes the form of a wave-patterned mass. NASA says these features show that the dramatic environment, driven by wind and running water, or both, has brought unique geological features to the region. The research team said that the rock could provide insight into how the lake environment of ancient Mars has evolved, and that it is possible to trace a more complex history from the simple view that Mars changed from a humid environment to land.

On July 9, Curiosity took a picture of Strathdon using the mounted mast camera. NASA adjusted the image to reproduce what rocks and sand would look like on Earth. The next day, the rock was photographed again from a distance of 10 cm through MAHLI mounted on a robot arm. A few weeks before the shoot, the exploration area was taken in 360-degree panoramas.

Curiosity has been exploring Mars for 7 years already. The built-in nuclear power system will not last a few years, but more discoveries can be expected within it. NASA is planning on Mars 2020, so it is likely to have more data on Mars. Related information can be found here .
