TheIntroduction average relative velocity between a micrometeoroid and a spacecraft can reach 19–22 km/s, and the average relative velocity between space debrisSpace debris and a spacecraft can reach 10 km/s. The micrometeoroids and space debris seriously threaten the safety of the orbiting spacecraftsSpacecrafts. The space debris protectionSpace debris protection can be traced back to the 1950s, when the exploration of effective protectiveSpace debris protectionStructure and material structuresProtective structures based on ultra-high speed collision was started and extended to the “Apollo” program in the 1960s in order to ensure the safety of intercontinental ballistic missiles and deep space probes and to understand the damage effect of debris and meteorite collision on spacecraftsSpacecrafts.
