It is a spacecraft with wheels that can adapt to harsh environments and conduct scientific exploration. It is a small, low-power, highly integrated robot. It has a dream of Asian children. High-altitude inspectors, said Zhao Xiaojin, head of the aerospace department of China Aerospace Science and Technology Corporation. "Chang'e III" moon inspection detector consists of mobile, structural and institutional, navigation control, integrated electronics, power supply, thermal control, measurement and control data transmission and payload system. From the model point of view, it has a directional antenna and several sun sensors on its head, with solar wings on both sides, many antennas on the tail, and navigation cameras and panoramic cameras on the right and back. It has a foot on six "hot wheels" like mobile devices, abdominal "secret device" most, including infrared imaging spectrometer, obstacle avoidance camera, robotic arm, laser bitmapper and so on. The Chinese Moon Vehicle is mainly developed by the fifth institute of the Aerospace Science and Technology Group. It has a weight of 120 kilograms, a load of 20 kilograms and a lifespan of 3 months. It can continuously travel 10 kilometers within a range of 3 kilometers on the moon, with automatic obstacle avoidance and other functions. Under the lunar rover, there is also a moon survey radar that will cut the depth of 100 meters below the moon to detect. In addition, it has a robotic arm that can be sampled in lunar and lunar rock for on-site testing. At the same time, the lunar rover will use solar energy and nuclear energy as energy sources. Since the moon's day and night intervals are equivalent to approximately 14 days on the earth, when the night falls, in order to prevent the on-board instruments from being frozen below the cold temperature of minus 100 degrees Celsius, the lunar rover must use the energy of the nuclear battery to keep warm and maintain the ground. communication. When the new daylight comes, the battery can work on solar energy again. "Parcel Sleep" guarantees overnight stay The day on the moon is equivalent to more than 27 days on Earth. The moon's day and night intervals are equivalent to 14 days on Earth. In addition, the temperature difference between day and night of the moon is large, the temperature of the daytime is as high as 130-150 degrees Celsius, and it can drop to minus 180-180 degrees Celsius at night. After experiencing a very low temperature, "wake up overnight" will be the biggest problem that the rover will encounter. Some experts believe that the difficulty of surviving on the moon is no less than landing on the moon. Because the night of the moon is low in temperature and time is long, it can be described as “long nights hardâ€. "The lunar rover must work for at least 3 months, which is equivalent to about 6 days and nights of the moon. There is no long time for the sun, and the lander and the lunar rover rely on the sun to generate electricity. This problem must be solved first." Ye Peijian said . In order to solve this problem, technicians designed retractable solar panels for the lunar rover. They were deployed during daytime power generation and closed at night, “just to wrap instruments inside.†This "wrap-around sleep" helps to ensure that the instrument will not lose temperature, protect various instruments from being frozen, and have surplus electricity "waking up on their own" on the next morning on the moon, and launching solar panels to greet them New day sunshine. In addition, during the day, the windsurfing board can also adjust its angle to avoid being overheated by sunlight. Autonomous navigation and ground remote control combined In order to achieve survival in extreme environments, the lunar rover thermal control system fully utilizes components such as a heat-conducting fluid circuit, thermal insulation components, a heat-dissipating surface design, an electric heater, and a isotope heat source, and can withstand 180 degrees Celsius to 150 degrees zero. Extreme temperature. The working cabin temperature can be controlled from minus 20 degrees to minus 50 degrees. “The lunar surface is soft, bumpy, and there are many obstacles. The lunar rover can sense and recognize the lunar surface environment and obstacles, and then plan the path of the tour. The lunar rover adopts a combination mode of autonomous navigation and ground remote control during lunar patrols. Li Benzheng, deputy commander of the lunar exploration project and director of the Lunar Exploration and Space Engineering Center, said. To enhance the safety factor, the technicians also designed a ground support system for the lunar rover. On the ground, they can also control the direction and motion of the lunar rover. The lunar rover will transfer the acquired data to the ground in real time. In terms of communication, "double insurance" has also been designed. The lunar rover can communicate directly with the ground and can communicate with the earth through the lander to ensure smooth communication. During the three months of the lunar surface inspection, the lunar rover will rely on various advanced equipments to carry out three-dimensional optical imaging and infrared spectrum analysis on the lunar surface, carry out scientific detection of lunar soil thickness and structure, and conduct on-site analysis of the main elements of the lunar surface material. The data it returns will help people understand the mysterious moon more directly and accurately. Landing Landing at 4 meters from the moon The Moon’s soft lander buffered through a reverse thrust rocket, landed slowly on the surface of the moon, and the hatch was opened, and an inclined ladder was automatically popped up. The lunar rover slowly stretched out and curled up, adjusted its posture, stepped out of the cabin door, slid down the inclined ladder, and began to walk on the moon... the academician of the Chinese Academy of Sciences and the chief scientist of China’s lunar exploration project Ouyang Ziyuan This once described the scene of the future of the Chinese moon carriage on the moon. "After reaching the lunar orbit, the lunar rover will be carried by the lander and controlled by a variable-force liquid rocket launcher. It will be measured by various optical, microwave, and other sensors. It will hover and translate at a height of 100 meters on the surface of the moon to evade rocks and Pits and other obstacles, choose the best landing point to slowly land on the surface of the moon.†Zhao Xiaojin, Director of Aerospace Department of China Aerospace Science and Technology Corporation said. Because there is no air on the lunar surface, the lunar rover needs to turn on the engine when it is going down, push it up and down, and slowly fall to a position 4 meters away from the moon. After that, the engine will be extinguished and the instrument will use a free-fall mode to make a soft landing on the moon. . At the same time, the lunar rover will implement autonomous navigation and be able to direct the instrument to operate and eventually transmit the data back to Earth. Li Benzheng, deputy commander of the lunar exploration project and director of the Lunar Exploration and Space Engineering Center, introduced that the Chang’e III mission is planned to be implemented in December this year to realize the first time that China’s spacecraft has made a soft landing and inspection of extraterrestrial objects. China's self-developed lunar rover, which has attracted much attention from the outside world, will realize zero-distance contact with the moon for the first time. It is understood that Chang'e III is responsible for the second phase of the “falling moon†task of China’s lunar exploration project. The second phase of the lunar exploration project is the second step of the three-step walk, drop, and return of the lunar exploration project in China. Chang'e III will realize a soft landing on the lunar surface and carry out in-position detection and lunar surface inspection. The lunar rover carried by Chang’e III will “walk†on the surface of the moon to conduct inspections.
