NASA has discovered the geological mystery on Mars

The US aerospace agency (NASA) said the autonomous robot Opportunity had a new discovery that made geologists curious and excited.

The device that landed on Mars in 2004 has passed a bare rocky beach with particles of 1/8 inch (3mm) in diameter, something scientists have never seen before. .

Kirkwood Highway Stone Beach

Referring to the new image sent from Mars, the principal analyst of Opportunity, Steve Squyres at Cornell University in Ithaca, New York, USA said: "This is one of the most unusual photos in The whole mission of Opportunity We have never seen such dense particles in a rocky outcrop on Mars. "

At first glance, researchers thought these objects were similar to high iron content spherical particles, found near the Opportunity landing site. These particles are formed when minerals separate from water and precipitate into hard particles. They are part of the evidence that Mars once had water.

However, when considered carefully, this new finding "differs in density, structure, composition and distribution". It will take some time to find the answer to this phenomenon.

The Opportunity vessel detects the tiny globules on the Kirkwood Highway stone dump in Cape York area on the western edge of the Endeavor Hole.

Although it has completed its main mission more than 8 years ago, it has so far probed for Opportunity to continue new tasks that are not part of NASA's program.
