However, the image of Mars is black and white. According to relevant sources, this imaging mode uses black and white imaging, which is the main reason why the first image of Mars is black and white.
Of the eight planets in the solar system, Mars is the closest to the Earth. Everyone knows that the earth is blue, but Mars looks red. Why do two planets so close look so different?
The first on earth? Messenger pirate 1? The lander made a soft landing on the surface of Mars. Two days later, the first color photo of the Martian world appeared in newspapers and TV. The photo showed that the Martian sky was blue. A few days later, experts released a photo of Mars with re-corrected color. The sky there turned purple and pink. It was later confirmed that the basic color of the Martian sky was orange-red.
The atmosphere of Mars is very thin. It is reasonable to say that its sky color is similar to that seen at an altitude of 30 thousand meters on the earth, and it is blue and purple. However, Mars is covered with fine brown sand and often windy, and there is a lot of dust floating in the air. These dust particles scatter the red light of the sun, making the sky on Mars appear red. ?
Finally, popular science: Mars is basically a desert planet, with sand dunes and gravel all over the surface and no stable liquid water body. The atmosphere dominated by carbon dioxide is thin and cold. The thin atmosphere on Mars is mainly composed of carbon dioxide (95.3%) plus nitrogen (2.7%), argon (1.6%) and trace oxygen (0. 15%) and water vapor (0.03%). The average atmospheric pressure on the surface of Mars is only about 7 millibar (less than 1% on the earth), but it changes with the height. The deepest part of the basin is as high as 9 millibar, while the top of Olympus is only 1 millibar. But it is enough to support hurricanes and big storms that occasionally sweep the whole earth.
