The risk of asteroid impact on the Earth is a common threat to mankind, and effective prevention and disposal measures against it have attracted great attention from the international community.Research on asteroid defense not only concerns the survival and development of human civilization, but also plays an important role in frontier scientific innovation and engineering technology development.This paper summarizes the asteroid impact missions that have been or are being implemented in the world, and analyzes the characteristics of asteroid impact defense missions.On this basis, a demonstration and verification mission plan of “accompanying observation+impact+accompanying observation” is proposed, and the mission plan, design of important links and key technologies are elaborated.
