China's first Mars exploration mission was established at the beginning of this year, and it is planned that in July and August 2020, at the Wenchang Cosmodrome in Hainan, the Long March 5 carrier rocket will directly send the Mars probe into the geo-fire transfer orbit, and the Mars probe will be captured by Mars after about 7 months of patrol flight, achieving the three goals
of "orbit, landing and patrol" at one time.
Mars is up to 400 million kilometers from Earth, and in 2020, China's first Mars exploration achieved the three goals of "orbit, landing, and patrolling", which is the first time that other countries have never implemented Mars exploration, and the challenges are also unprecedented
.
The Lunar Exploration and Space Engineering Center of the State Administration of Science, Technology and Industry for National Defense released the design configuration of
China's first Mars probe and rover on the 23rd.
The picture shows the appearance of
the Mars rover.

As can be seen from the released pictures, the rover is equipped with 4 "big wings" - solar panels
.
Sun Zezhou, chief designer of China's first Mars exploration mission project, said that like the Jade Rabbit lunar rover, the rover relies on solar
energy for energy acquisition.
Due to the small light intensity of Mars, the Martian atmosphere has a cutting effect on sunlight, and the energy supply of the rover is more difficult than that of the lunar rover, which has two more "wings" than the "Jade Rabbit"
.
Sun Zezhou said that the rover has a design life of 3 Martian months and a design weight of more than 200 kilograms
.
In order to adapt to the special environment of Mars, the rover will be made
of composite memory fiber, aluminum-based silicon carbide, honeycomb sandwich and other materials.
The probe will carry 13 scientific payloads, including a camera for global remote sensing of Mars and a radar for detecting shallow structures beneath Mars, to detect
the morphology, soil, environment, atmosphere, water ice distribution, physics and internal structure of Mars.
"The landing site of the landing rover is tentatively set at the low latitude of Mars
.
" Ye Peijian, academician of the Chinese Academy of Sciences and consultant of the Mars rover system, said that the landing rover separated from the orbiter and entered the Martian atmosphere, and after aerodynamic shape deceleration, parachute deceleration and thrust reverse engine power deceleration, and finally descended and landed on the surface of Mars, the rover drove away from the landing platform and began the surface patrol and exploration
of Mars.
Liu Jizhong, deputy commander of China's first Mars exploration mission project and director of the Lunar Exploration and Space Engineering Center, said that he hoped that by carrying out this global collection of project names and graphic identification, the general public can enhance the deep understanding of the significance of China's implementation of Mars exploration projects, and encourage young people to pursue scientific knowledge strongly.
Better display the national image
of China's Mars exploration project.
Through the first Mars exploration, the goal of
"orbiting, landing and patrolling" will be achieved in one step.
