Perseverance Rover from NASA makes a significant finding
Perseverance rover collected organic materials from a Red Planet river delta.
The rover is looking for signs of early Martian life.
The US Space Agency is planning a mission to bring Mars samples back to Earth.
Ken Farley, a project scientist, said the delta rocks have the most organic material. This is different from mission findings.
The Mars rover has taken 12 samples after gathering four in the delta, a former lake bed.
The latest discovery was made in a location where silt and salts accumulated into a lake billions of years ago.
According to the researchers, these sediments originated in conditions that supported life.
