What else are the human probes to Mars?
Mars itself has two natural moons: Phobos and Phobos, which are irregularly shaped and may be captured asteroids. There are four Mars probes in orbit: Mars Odyssey, Mars Express, Mars Global Surveyor and Maven. In addition, there are many Mars rovers and landers on the surface of Mars, including curiosity and insight, as well as Mars Pathfinder, Phoenix, courage and opportunity, which have ended their missions.
According to the observational evidence and relevant data, Mars may have covered a large area of water before, and similar phenomenon of groundwater gushing was also observed. The Antarctic ice cap retreated partially. Radar data show that there are a lot of water ice under the surface of the two poles and middle latitudes.
The Martian atmosphere is dominated by carbon dioxide, which is thin and cold. It is full of impact craters, canyons, sand dunes and gravel. There is no stable liquid water. The southern hemisphere is an old highland full of impact craters, while the northern hemisphere is a relatively young lowland plain.
Mars is called ares in the west, perhaps because of its bright red color, so Mars is sometimes called "red planet". Before the Greeks, the ancient Egyptians worshipped Mars as the God of farming. Later, the ancient Greeks took Mars as Ares, while the ancient Romans inherited the Greek myth and called it "Mars". In Nordic mythology, Mars is the God of war. The name of March also comes from Mars.
Mars was called "Yinghuo" in ancient China. This is because Mars is red, fluorescence is like fire, and it symbolizes fire in the five elements. Its brightness often changes. Moreover, it moves in the sky, sometimes from west to East, and sometimes from east to west. The situation is complicated and confusing, so it is called "Yinghuo" in ancient China.
