For many people, rocks are worthless, but for NASA scientists, they are extremely valuable, having opened the door to discovering unknown things about the 'brother' planet. Our earth.
Recently, the US Aerospace Agency (NASA) has published a picture of a rock specimen collected by Curiosity explorer ship on the surface of Mars. This stone is named Strathdon , and it has prompted many things for scientists about the planet's form when it was in a "wet" state.
This stone looks like a collection of tiny fragments, which can only be formed in places where clay is deposited and hardened into layers stacked on a large scale. Although the Curiosity had previously been approached with the formation of many different types of sediments, this particular piece of rock had a very unique characteristic.
According to NASA's explanation, this is seen as proof of the existence of water currents, winds, or even the above two elements, at the surface of Mars.
'We have seen the evolution of ancient lakes recorded in these rock samples,' said Valerie Fox, a professor at the California Institute of Technology, USA. 'Not only does it stop at a stationary lake, but it also helps us continue to develop a perspective from the viewpoint that Mars simply moves from wet to dry. Instead of a sequential, historical process of forming water sources here is more complicated than we thought '.
An ancient stream of water crept on the surface of a Mars warming with a thicker atmosphere than Earth, which at first glance seemed like a sign of life, but this has not yet been scientists. confirm. Although Curiosity has long discovered that the planet is still very suitable for the life of microorganisms, researchers still cannot verify whether there is life on Mars.
