Scientists believe that recently gathered samples of NASA's perseverance Mars Rover is likely to contain organic samples.

NASA confirmed that the four recent samples are sedimentary rock samples from the Red Planet's ancient river delta. 

They mark the first ever sedimentary rock samples gathered  from another planet.

The rocks being investigated on the delta have the highest concentration of organic elements, as reported by project scientist Ken Farley.

The space agency believes that the present location of the rover is a top prospect for finding evidence of microbial life.

The four newest samples were gathered from Skinner's crater ridge and wildcat ridge between July 7 and Aug 3.

Researchers will examine the sample for evidence of microorganisms but will need some time to do so.

The MARS sample return campaign is run by European Space Agency and NASA.

The rover has received a total of 13 samples so far

The goal is to collect a total of 38 samples.

"To undertake the challenge and the expense of a Mars sample-return mission, we need a great suite of rocks to bring back," 

stated by, Laurie Leshin.

Previously, the sand, mud and dust that makes up the Wildcat Ridge could also have the evidence of survival of life.

Once studied and researched, it can be conluded about the presence of organic elements.
