A NASA spacecraft will look for signs of life on Mars – unomassive


The next Rover goes to a crater of 45 kilometers in diameter, called Jezero, where it will collect samples of rocks and soil

A NASA spacecraft will look for clues about the existence of life on Mars by examining the rocks of an ancient lake and a delta, two geographic features that could preserve signs of ancient organisms, the space agency said.

"The delta is extremely good at preserving biopyrmas, that is, samples of life"

NASA has been debating for five years the best place to land its spacecraft, which will travel to space in July 2020.

After studying more than sixty different locations on Mars, NASA has announced that its spacecraft – a spacecraft designed to move on the surface of the planet – will go to a 45-kilometer-diameter crater called Jezero where it will collect samples of rock and ground

In a teleconference, scientist Ken Farley, who works for the Mars 2020 project at NASA's Jet Propulsion Laboratory (JPL), explained that the crater is the former home of a river, so it could have retained signs of organic molecules and microbes.

"First of all, lakes on Earth are good places for life, and inevitably there is some life in them." The second thing is that the delta is extremely good at preserving bioforms, that is , samples of life, "explained Farley.

In addition, the ancient 250-meter deep lake has five different types of rocks: clays and carbonate rocks, which can preserve signs in ancient organisms, including volcanic rocks, that may provide clues to the volcanic evolution of Mars.

The goal, said Farley, is to first find out how the environment on the red planet was and then try to understand what kind of life might have inhabited it.

The results of previous special missions show that Mars was not always a red desert but had a large volcanic activity (as craters show) and that it was also capable of holding liquid water on the surface, which means that it could have counted with an atmosphere suitable for life.

NASA has begun in 2012 a program aimed at launching a Mars exploration vehicle in 2020.
