The presence of clay confirms that in the past, the Gale crater contained a significant amount of water.
The Rover Curiosity found on the slopes of mount sharp in Gale crater, the largest for today of Martian clay deposits that probably formed at the bottom of an ancient lake or river.
Studying the breed will help scientists learn more about Mars water, writes reports the online edition of the Chronicle.info with reference to nv.ua.
The orbiters were the first clay found on mount sharp. When NASA chose the Gale Crater as the landing site for MSL Curiosity, clay on mount sharp was one of the goals of the Rover.
The Rover Curiosity has drilled the well and took two samples, and now confirmed the presence of a large number of clay minerals in them. The presence of clay confirms that in the past, the Gale crater contained a significant amount of water. Most likely, the rocks in this region formed from layers of sediment and mud accumulated at the bottom of ancient lakes.
While a small amount of clay detected in other areas of Mars, the recent samples contained the greatest number of clay minerals known at the moment.

“Such deposits of clay — one of the main reasons why we chose the Gale crater, and refused other options for the landing of the Rover. Our tools are ideally suited to reveal its secrets,” — said Scott guziewicz, one of the participants of the science team of Curiosity.
