Yutu lunar rover carried out a geological survey of 1 14m around crater C 1, and obtained rich and precious lunar geological data. The results of many scientists' work based on these materials are published in the world's top scientific magazine Science.
The data detected by the lunar radar carried by Yutu shows that the surface of Chang 'e-3 landing area is divided into at least 9 layers, indicating that there have been many geological processes there, which is of great significance for exploring the evolution history of lunar magma and its later transformation. This is the first time that scientific achievements have been published in top international academic journals since the implementation of the China Chang 'e lunar exploration project.
Yu Tu's technological breakthrough;
Prior to this, there were five lunar rovers launched and successfully operated in the world, of which two were unmanned lunar rovers, all launched by the Soviet Union in the 1970s, and the other three were manned lunar rovers, namely Apollo 15, Apollo 16 and Apollo 17 of the United States.
The Yutu lunar rover in China is also an unmanned lunar rover with a mass of about 140kg. Compared with the Soviet lunar rover, it is "small", small and refined, and it is enough to complete the task and save costs.
The unmanned lunar rover is more difficult because there are many instruments on it. It is necessary to ensure that the instrument can work normally in the unmanned state. Manned lunar rover is mainly used as a means of transportation to expand the activities of astronauts on the moon. There are basically no instruments on it, so it is relatively easy for astronauts to drive.
It has been nearly 40 years since the last lunar rover landed on the moon, and the electronic equipment and detection instruments are not comparable to those years. In the past, it was impossible to choose materials, drive systems or testing instruments. Therefore, it is certain that the lunar rover in China is more advanced than before. Although it is not the most advanced in the world today, it is definitely not a repetition of the 1970s.
