Self-deploying, rapid response systems for crucial assets, released after the start of the Kessler cascade. Dispersed as a cloud around vital assets (ISS, critical comms satellites), these canisters release micro-meteoroid and orbital debris (MMOD) shielding particles upon detonation. This localized 'armor' provides a temporary period for emergency operations or controlled deorbiting. Intended to mitigate some damage of a debris cascade.
