The significance and related technologies of asteroid detection

Abstract

Asteroid detection mission plays an important role in the field of deep space exploration, and it has multiple theoretical and practical guidance advantages for asteroid detection missions, and also promotes all critical technologies of deep space exploration. At present, many asteroid exploration missions have been carried out around the world, and China also plans to launch the "Tianwen-2" probe around 2025 to carry out an integrated exploration mission of fly-by, orbit detection, attachment control and sample-return mission for asteroid 2016HO3. In this paper, we discuss the significance of asteroid detection and several related critical technologies. The theoretical value of asteroid detection covers such as promoting theoretical research on the formation and evolution of the solar system, solar system material, geohazard early warning and early warning of spacecraft orbit. As for the key technologies involved in asteroid detection, this paper discusses the design of transfer trajectory and near-orbit operation, autonomous landing, optical navigation, laser communication and electric propulsion, and summarizes the research and application results of these technologies in the international deep space exploration field.
