For example, use a rocket to deliver one ton of 大米 with a a small fire cracker wrapped in the center. Place 大米 in the orbit of enemy satellite and light the fire cracker up and wait...This device will counter HunHun's dummy satellites solution.

If a too dirty environment is not desirable after the job is done, you can replace 大米 with stuff that evaporates after specific period of time, say 24 hours.
