China started the Mars exploration mission and named Tian Wen-1.

April 24, 2022 is China Aerospace Day, and on this day, Mars exploration was launched, and the name of the Mars exploration mission was announced as Tian Wen-1, which will also record the further development of China's space industry. So here's a detailed introduction to constellation knowledge for everyone!

China launched a Mars exploration mission named Tian Wen-1. On April 24th, the launching ceremony of China Aerospace Day 2022 was held on the website of the National Space Administration and other online platforms. The name and logo of China's first Mars exploration mission were announced at the ceremony. China's planetary exploration mission was named "Tian Wen Series", the first Mars exploration mission was named "Tian Wen No.1", and the subsequent planetary exploration missions were numbered in turn.

China's first Mars exploration mission will be completed in three steps. First, we should be able to observe the whole of Mars on a global scale; Second, land on Mars; Third, the rover will leave for a patrol survey on Mars. "There are many difficulties. If completed, it will be the first time in the world to accomplish three goals in one task. The realization of this project is a great innovation. " Ye Peijian, an aerospace expert, pointed out. Exploring Mars for the first time will achieve three goals at a time, which is unprecedented in other countries and faces unprecedented challenges. This means that China's first Mars exploration mission will not only realize global remote sensing around Mars, but also break through key technologies such as Mars entry, descent, landing, patrol and long-distance measurement and control communication. Let's really go into deep space, approach Mars and unveil her mystery.

Not long ago, China Aerospace Science and Technology Corporation held a press conference to introduce the specific implementation steps of China's Mars exploration mission, including: launching China's first Mars probe into the ground fire transfer orbit by using the Long March 5 rocket, and then braking near the fire point through multiple orbital maneuvers and midway corrections with the support of the ground measurement and control system, entering the elliptical orbit around the fire and running to the selected entry window. The probe will perform orbit lowering control, release and landing. After the rover entered the atmosphere of Mars, it achieved a soft landing through aerodynamic shape, parachute, engine, multi-stage deceleration and landing recoil. After the rover is separated from the landing platform, it will carry out regional patrol detection and some related engineering practice activities. Orbiter will provide relay communication link for rover and conduct scientific exploration around it.
