Beijing, May 15 (Xinhua): The Lander wearing China's first Mars Rover has been successfully touched on the Red Planet on Saturday morning from Beijing.

It's the first time China has landed a probe on a planet other than Earth.

Tianwen-1, consisting of an orbiter, a lander and a rover, was launched from the Wencang Spacecraft launch site on the coast of Hainan Province From the island of Southern China, on July 23, it was the first step in China's planetary exploration of the solar system, with the aim of completing the orrid. , landing and wandering on the red planet on a mission.

The name Tianwen, which means questions to heaven, comes from a poem written by the old Chinese poet that Yuan (around 340-278 BC). China's first Mars Rover is called Zhurong after the god of fire in ancient Chinese mythology, which echoes with the Chinese name of the red planet: Huoxing (the planet of fire).

The spacecraft entered the orbit of Mars in February after a trip of almost seven months through space, and spent more than two months examining the possible Landing sites.

At the beginning of Saturday's hours, the spacecraft began to descend from its parking orbit, and the entrance capsule that encloses the landing and the rover separated from the orbiter at approximately 4 am

After flying for approximately three hours, the entrance capsule is thrown into the red planet and entered the atmosphere of Mars at an altitude of 125 km, starting the most risky phase of the entire mission.

First, the aerodynamic form specially designed from the input capsule slows down with the friction of the Martian atmosphere Re. When the speed of the spacecraft was reduced from 4.8 km per second to approximately 460 meters per second, a huge parachute that covers an area of ​​approximately 200 square meters was deployed to continue reducing the speed less than 100 meters per second.

The parachute and the outer shield of the spacecraft were lonfigured, exposing the landing and rover, and the retrorecket on the lander was fired to reduce the speed of the boat At almost zero. .

About 100 meters on the Martian surface, the ship was hovered to identify obstacles and measure the slopes of the surface. Avoiding obstacles, selected a relatively flat area and descended slowly, touching securely with its four buffer legs.

The Craft's Pulmet through the Martian environment, which lasts about nine minutes, was extremely complicated without control of land, and had to be made by the spacecraft, Geng Yan said, an official of the CNSA exploration and lunar spatial program.

"Each step had a single opportunity, and the actions were closely linked. If there was no defect, the landing would have failed," Geng said. EndItem
