NASA's spacecraft will look for signs of life on Mars – unomásuno



The next Rover will go to a 45-kilometer crater called Jezero where he will collect samples of rocks and soil

A NASA spacecraft will look for clues about whether Mars had ever lived, analyzing the rocks of an ancient lake and the delta, two geographic features that could preserve the signs of ancient organisms, the US space agency said.

"Delta is exceptionally good in preserving biofuels, ie life samples"

NASA has been discussing for five years the best space to land a spacecraft that will travel to space in July 2020.

After exploring more than sixty different locations on Mars, NASA announced that its spacecraft – a spacecraft designed to move around the planet's surface – will be heading to a 45km diameter crater called Jezero where it will collect rock patterns floor .

In a conference call, scientist Ken Farley, working for the Mars 2020 project at NASA's JPL, explained that the crater is a former home of the river so it could retain signs of organic molecules and microbes.

"It's very attractive from a scientific point of view, first of all, the lakes of the Earth are good places to live and there is inevitably something in them.The second thing is that the delta is extremely good for preserving bioforms, "explains Farley.

In addition, the ancient lake, which is 250 meters deep, has five different types of rocks: clay and carbonate rocks that can retain signals from ancient organisms, to volcanic rocks that can offer clues to the volcanic evolution of Mars.

The goal, Farley said, was first to find out what was the environment on the red planet, and then try to figure out what life he could have.

The results of previous special missions show that Mars was not always a red desert but had a great volcanic activity (as the crater shows) and that it also had the ability to hold water on the surface, meaning a living-friendly atmosphere .

NASA launched in 2012 a program that aims to launch a Mars exploration vehicle in 2020.
