Detailed explanation-1: -Scientists from the National Aeronautics and Space Administration (NASA) released the first portions of the multispectral maps of the surface of Mars on June 29, 2022. The multicoloured 5.6 GB map covers 86 percent of the Red Planet’s surface.

Detailed explanation-2: -Giovanni Cassini, William Herschel, Robert Hooke, and Christiaan Huygens all tried their hand at drawing the planet’s basic features in the 17th and 18th centuries. But German astronomers Johann Mädler and Wilhelm Beer made the first true map of Mars.

Detailed explanation-3: -Once astronomers ascertained that at least some of the features were stable formations, mapping Mars became a legitimate endeavor. In 1840 the German astronomers Wilhelm Beer and Johann von Mädler produced the first map of Mars, shown here in Mädler’s “Popular Astronomy” (1861).

Detailed explanation-4: -The first person to draw a map of Mars that displayed terrain features was the Dutch astronomer Christiaan Huygens. On November 28, 1659, he made an illustration of Mars that showed the distinct dark region now known as Syrtis Major Planum, and possibly one of the polar ice caps.

Detailed explanation-5: -This is the first photograph ever taken on the surface of Mars. It was obtained by Viking 1 just minutes after the spacecraft landed successfully on July 20, 1976.
