How is Chang 'e's landing on the moon going now? detail

Schematic diagram of each stage: As early as 1994, Chinese space science and technology workers studied the necessity and feasibility of lunar exploration activities, completed the technical scheme of lunar exploration satellite in 1996, and completed the research on key satellite technologies in 1998, and then carried out in-depth demonstration. After 10 years of brewing, it was finally determined that the whole lunar exploration project in China was divided into three stages: "around", "down" and "back" The first step is to "orbit", that is, launch China's first lunar exploration satellite, break through the flight technology to extraterrestrial bodies, and realize the lunar exploration satellite's flight around the moon. Through remote sensing detection, we can obtain three-dimensional images of the lunar surface, detect the contents and material types of useful elements on the lunar surface, detect the characteristics of lunar soil, and detect the space environment of the earth and the moon during the lunar exploration satellite's flight to the moon. The first lunar exploration satellite "Chang 'e I" was launched on June 24th, 2007. The second step is "down" from 2007 to 20 10. That is, launch a lunar soft landing device, break through the landing technology of extraterrestrial bodies, carry out lunar soft landing and automatic patrol survey with lunar patrol detectors, detect the topography, geological structure, chemical and mineral composition and lunar environment of rocks in the landing area, carry out on-site detection and sampling analysis of lunar rocks, and carry out solar-terrestrial-lunar space environment monitoring and moon-based astronomical observation. The specific scheme is to use patrol cars and automatic robots that landed safely on the lunar surface to detect the composition of rocks and minerals in the landing area, measure the heat flow and surrounding environment at the landing site, and take high-resolution photography and on-site detection or sampling analysis of lunar rocks, so as to provide chemical and physical parameters of the lunar surface for future lunar base site selection. The third step is "back", and the time is set at 20 1 1 until 2020. That is, launch the lunar soft landing device, break through the technology of extraterrestrial objects returning to Earth, automatically sample the lunar samples and return them to Earth, analyze and study the samples on Earth, and deepen the understanding of the origin and evolution of earth-moon system. The goal is to patrol the moon and return samples. When the three steps of "circling, falling and returning" are completed, China's unmanned lunar exploration technology will be mature, and the day when China people will land on the moon will not be far away.
