IT Home reported on July 26 that NASA's "Perseverance" rover is carrying out a scientific exploration mission on Mars.Signs of ancient life have been found in a rock.This has delighted scientists on the mission team, but further analysis is needed to confirm the finding.

"Perseverance" discovered an arrow-shaped rock on Mars. Based on its chemical characteristics and structure, scientists initially judged that it may have been formed by microbial life billions of years ago.

Scientists nicknamed the rock Cheyava Falls, and Perseverance's instruments detected organic compounds, which are the predecessors of life as we know it.

Perseverance also discovered dozens of millimeter-sized spots, each surrounded by a dark ring that resembles leopard spots in appearance. These rings contain iron and phosphates, which can also be seen on Earth and are the result of chemical reactions caused by microorganisms.

Morgan Cable, a scientist on the Perseverance team, released a video yesterday (July 25), saying: "In previous explorations of Mars, we have never found calcium sulfate, iron and phosphate together." IT Home attached the relevant video as follows:

Cheyava Falls is located on the edge of a 400-meter-wide (437-yard-wide) ancient river valley named Neretva Vallis.

Scientists suspect that this ancient river channel was carved out long ago by water pouring into the Jezero crater, and that the Neretva River valley runs along the inner walls of this area.
