JAXA Special Publication: Proceedings of the 7th Space Debris Workshop
Components of JAXA's spacecrafts are identified effects on debris collision before its launch. If the risk is not acceptable, a debris shield is added to the component. An aluminum alloy plate has high reliability since it has been used as a shield of the ISS. For an unmanned spacecraft, however, the effect on the total weight is not ignorable. A lot of light-weight bumpers have been developed before now. Almost all new bumpers have not finished assessments of protective abilities against space environment. This study investigated shielding effects of MLI blankets. The MLI blanket captured projectiles of 0.lmm in diameter when its areal density was increased by using thick reflectors. If an outer film was covered with ITO (Indium-Tin Oxide), the projectile fractured more. An outer film is considered to influence with fragmentation of debris. Moreover, embossed reflector films seemed to improve shielding effects of a MLI blanket.
