According to reports EconomyOnline Mars images show how water significantly contributed to the formation of the Red Planet billions of years ago, according to Faraday. How can this give us clues to looking for evidence of ancient life on Mars?
In February, NASA’s Perserence rover landed at the mouth of the tide, where scientists suspected how a long-extinct river that fed the lake had collected sediments in a butterfly-shaped delta visible from space. .
The scientists analyzed using high-resolution images taken by rocks from the Transversion rover off the coast of the delta. The layers inside the rocks reveal how it is formed.
Astronomers found similarities between the characteristics of the rocks seen from the crater floor and the patterns of the Earth’s river deltas.
Images of the three lower layers in the early presence and continuous flow of water on the surface of Mars show that the planet was warm and humid enough to support the hydrological cycle (water cycles) about 3.7 billion years ago.
The highest and newest layers have boulders more than one meter in diameter that may have been moved by heavy flooding. But this fine-grained sediment is the base layer that will probably be the target of sampling to detect signs of possible extinct life on Mars.
These findings will help researchers figure out where to send the rover for soil and rocks that may contain valuable “biomarkers” of Martian life forms.
Finding out if there might be life on Mars’s main mission is “endurance”; A project that took decades to develop and cost billions of dollars.
Understanding that Mars may once exist is one of humanity’s “deepest” discoveries. Over the years, the multifunctional rover has collected 30 rock and soil samples in sealed tubes and finally sent them to Earth for laboratory analysis in the 2030s.
Last month, scientists announced that Perseverance had collected two rock samples at the crater, indicating that they had been in prolonged contact with groundwater.
Their hope is that the specimens may have hosted ancient microbial life at one point; Evidence of this can be trapped by salt minerals.
The “Endurance” rover landed on the surface of Mars on February 18 and during this study, remote images were examined on Mars during its first three months.
The Endurance is about the size of a long-wheelbase car with 19 cameras, a two-meter (seven-foot) robotic arm, two microphones, and a set of advanced tools. One of these devices is called the SuperCam, which uses a laser to examine rocks from a distance, examining their vapors with a device that detects their chemical composition.
It took seven months for the Persevers rover to travel from Earth to Mars with its sister Ingenuity; A small helicopter whose rotors have to spin five times faster than Earth versions to be able to take off in the very dense atmosphere of Mars.
The plan is for the rover to cross the delta at the crater and then the shore of the ancient lake, eventually exploring the edges of the crater.
