Abstract: Hypervelocity impact dynamics and spacecraft protection as an important part of hypervelocity impact technology, is reviewed in this paper. Its research background is outlined. Its research progress covers the following five aspects: making hole in the thick board, penetration in the critical thick board, forming debris cloud from the thin board, experimental simulation technique and numerical simulation technique. The damage effect of hypervelocity impact spacecraft is analyzed. The spacecraft protection requirements are given, and the project design and performance of the spacecraft protection structure are discussed.
