In the history of human exploration of the solar system, Mars has always brought people infinite expectations and reverie. Up to now, there have been 47 Mars explorations in the world, including 22 in the United States and 20 in Russia, but two-thirds of the missions ended in failure.
This is enough to show that the road to fire detection is full of dangers. Although Tianwen No.1 started late, it has a high starting point, high efficiency, great challenges and strong innovation. Mars exploration in one step will create a precedent for human deep space exploration.

1February 15 17, the first Mars exploration mission, Tianwen-1, successfully carried out plane maneuver and captured the far fire point of the orbit. When the 3000N engine is ignited, the orbit is adjusted to a ring fire orbit passing through the two poles of Mars, and the height near the fire point is adjusted to about 265 kilometers.
202 1 First Mars Exploration Mission At 6: 29 on February 24th, Tian Wen-1 successfully implemented the third near fire braking, and entered the parking orbit of Mars with a near fire point of 280 kilometers and a far fire point of 59,000 kilometers, with a cycle of two Mars days.
On March 4th, 2002 1 year, NASA released three high-definition images of Mars, including two black-and-white images and1color image, which were taken by the first Mars exploration mission "Tianwen-1" in China.
