For example, multiple collision damages are possible for satellites with projected areas exceeding 10 m2. Efforts are required for mission assurance against debris. The protection design for critical components of a spacecraft, adding functions to complete self-disposal actions, etc. are considered. Almost all the debris experts in the world agree that the number of existing debris would continue to grow and the environment would go worse. Therefor, in addition to the mitigation efforts, more positive measures to remedy the environment should be globally discussed and implemented. In order to develop measures to remove debris, technology development is needed as well as international cooperation.
