China's first Mars car form exposure, what's your name?

On August 23, the "Global Call for China Mars Exploration Project Name and Graphic Marking Activity" was formally launched in Beijing. At the event, the appearance of the first Mars rover and rover in China was also made public for the first time.

As shown in the figure, the most prominent feature of China's Mars is its possession of four "big wings" - solar panels. According to Sun Zezhou, the chief designer of the Mars exploration system for the first Mars exploration project in China, this is due to the fact that Mars is relatively far from the sun and the Martian atmosphere reduces sunlight. Therefore, the illuminance of sunlight on Mars is relatively small, in order to guarantee a rover. The energy supply, solar panels therefore occupy a larger area.

Sun Zezhou also said that the design life of the Mars is 3 Mars months (about 93.7 Earth days) and the design weight is about 200 kg. In order to meet the special conditions of Mars, the Mars Rover will use a variety of materials such as composite memory fibers, aluminum-based silicon carbide, and honeycomb sandwich. The detectors will carry 13 scientific payloads, including Mars' global remote-sensing cameras and radars that probe Mars' shallow and underground structures, to detect Mars' morphology, soil, environment, atmosphere, distribution of water and ice, physical fields, and internal structures.

Regarding the landing mode and location of the rover, Academician Ye Peijian, academician of the Chinese Academy of Sciences and Mars Rover System Consultant, said: â€œThe landing point of the Landing Patrol was tentatively set at the low latitudes of the northern latitudes of Mars.â€ When the Mars rover carries a landing patrol over a predetermined area, it will be separated from the landing patrol, and then the landing patrol will fall into the atmosphere of Mars by gravity torgue. After the aerodynamic shape deceleration, parachute deceleration, and reverse thrust engine power deceleration, etc. After landing on the surface of Mars, the rover will start and move away from the landing platform to begin the inspection of the surface of Mars.

It is reported that Chinaâ€™s first Mars exploration mission has been initiated at the beginning of this year. It plans to launch the Mars probe directly into the geothermal transfer orbit on the Long March 5 launch vehicle at the Wenchang Space Launch Site in Hainan in mid-2020. The â€œthree goalsâ€ were patrolling. This was the first time that other countries had implemented Mars exploration and the challenge was unprecedented.

Zhang Rongqiao, chief designer of China's first Mars exploration mission project, said that the maximum distance between Mars and the Earth is 400 million kilometers. At the same time, subject to the laws of celestial bodies, the most favorable Mars probe launch opportunity will occur every 26 months. From now on, there will only be 3 transmitters around 2020. Scientists need to successfully complete the mission in this only 3 chances. It is easy to imagine the difficulty and pressure.

According to the information of the conference, this solicitation will take more than four months and will be organized and implemented in five phases. The final identification of a Chinese Mars exploration project name and graphic identification will be finalized.
