Underneath the surface of Mars is blue-gray

The new image from the Curiosity probe shows that the lower part of the Martian surface is blue-gray instead of red.

Discover phenomena that have no answer on Mars

According to the "digging" result below the surface of Mars, the Curiosity detector detected colors in a combination of blue and gray. IBTimes said on March 3 that Curiosity searched at the third drill site at the top of the Telegraph, near Mount Sharp. The device here for half a year and collecting specimens helps scientists identify colors.

Like Earth, Mars is primarily formed from silicon, oxygen and contains a large amount of iron, magnesium, aluminum, calcium, and potassium. However, scientists from the US Aeronautics Agency (NASA) were surprised to discover silicon at the peak area called the Telegraph.

"When graphing the silicon to magnesium ratio and the silicon to aluminum ratio, we found that the Telegraph peak area has a ratio close to the limit we once knew," said Doug Ming, a project investigator. NASA's Curiosity project, says.

Mars is considered a red planet because there is iron oxide on the surface. The process of contacting with oxygen and creating rust and the cause of the planet's surface is red.
