NASA's Curiosity Rover has discovered sediments in the bottom of the Gale crater that are transmitted by water and wind. Monica Grady, a professor of planetary and space science at the Open University, claimed that "some bacteria" could live in such an environment. She said to today's BBC Radio 4 broadcast: "Definitely water. But it is said that the rover of stones that have been deposited in a very wet time, has gone to a time when he was dry with intermittent wetness.
BBC presenter Mishal Husain asked, "And what does that point to this shift? "
Professor Grady replied," Well, it does indicate that the climate on Mars actually did not change dramatically, but gradually over time, and then it would be a bit warmer and wetter, and then cold and dry.
"Now was the time these stones were laid down, the same time we first had evidence of petrified life on earth on Earth.

"And it may be that we are now in an environment where life on Mars is not too hot, not too cold, not too dry and it It could be that some bacteria were able to live in this environment.
At the beginning of the program, the scientist continued, "We are talking about a crater called Gale Crater, which is not too far from the Mars equator.
"In the eastern part of Mars, or only by the longitude, ie south of the equator.
"It's a giant crater created by the impact of an asteroid. Many, many billions of years ago, it gradually filled with feelings that became rock. "
Leading scientist William Rapin said," We went to Gale Crater because it preserves this unique record of a changing Mars. When and how the planet's climate began to develop is another mystery. "[1
Based on a series of mud cracks in a place called "Old" "Soaker", the team already knew that the area was getting drier at times. Given the similarity of Earth and Mars in their early days, NASA speculated that Sutton Island might resemble the salt lakes of South America's Altiplano.

Brooks and rivers flowing from mountain ranges into this arid plateau lead to closed basins similar to the old Gale crater of Mars. Lakes on the Altiplano are as strongly influenced by the climate as Gale.
Mr. Rapin said, "During drier periods, the Altiplano Lakes become flatter and some can dry out completely."
He added that the fact that they are free of vegetation makes them even look a bit like Mars. "
Taken together, the evidence points to Gale Crater and Mars generally as a place where life may have survived for some time.
] After the main mission is completed, the NASA rover will continue to investigate.  NASA's goal is to uncover the history of Mars and to learn more about how and where future missions can search for signatures that the old life may have left behind.  "Finding inclined planes is a big change, because the landscape is no longer completely under water, "said team member Chris Fedo, who specializes in the study of sedimentary layers at the University of Tennessee lakes behind it."  25]
