According to the research, the pictures taken from Mars show how water helped form the Red Planet’s terrain which happened billions of years ago, and proves that help can succeed in the hunt for ancient life.
NASA’s rover landed at Jezero crater in February, where scientists thought the river which went dry, once also created a lake, which dumped pieces of a fan-shaped delta that was seen from the orbit. The research released in Science looking for high-resolution photos that were by the cliffs that were old delta’s banks. The development of the cliffs is seen through layers inside the cliffs.
The Mars Reconnaissance Orbiter and other satellites provided fascinating new things about Jezero Crater’s history about water right from orbit. Scientists have discovered several geological surprises now that the NASA Persevere rover is giving close-ups from the ground
An astrobiologist from NASA and their colleagues in Florida found parallels between cliff features observed from the crater bottom and patterns in Earth’s river deltas.
According to the study, the structure of the bottom three layers proves the presence and constant flow of water, showing Mars was warm and humid enough to have a hydrologic cycle approximately 3.7 billion years ago.
The top and most recent ones are littered with stones measuring more than a meter in diameter, which were most likely transported there by severe floods.
However, the grained silt of the basal layer will most certainly be taken for finding the indications of long-extinct life if it existed on Mars.
The findings will help researchers in determining where to deploy the rover in search of soil and rocks that may hold valuable biosignatures of possible Martian living things.
We knew the delta had to be produced by water based on orbital photos. The major goal of determination, a project that took decades and cost billions of dollars to create, is to know whether life ever existed on Mars.
Over several years, the rover with many specialties will gather 30 rock and soil samples in sealed tubes, which will be sent to Earth for lab processing somewhere in the 2030s.
Scientists revealed last month that Perseverance had gathered two rock samples in Jezero that showed evidence of being in touch with groundwater for a very long time. Their aim is that the samples that previously stored ancient microbial life, proof of which might have been trapped by salt minerals.
Learning that Mars may have previously harbored life would be one of the deepest discoveries ever made by humans. It’s amazing to witness something that no one on Earth has ever seen before.
Perseverance landed on Mars on February 18, and the researchers examined long-distance photos that it took during its first three months there. It has 19 cameras, a two-meter long robotic arm, two microphones, a lot of future techs, and is about the size of an SUV.
The SuperCam is one of them, it is a gadget that scans rocks from a distance in order to examine their vapor with a device that shows its chemical makeup. The aim is for the rover to go over the delta, then the old lakeshore, and finally to the crater’s borders.
