if close enough, sensors should be able to tell something is a dummy, e.g., asteroid and MS balloons wouldn't have much mass

Also worth noting that up close, things like dummy balloons don't work other than blocking your view, but at a distance they might trick some unsuspecting pilots.

even with minovsky particle jamming, it might be close enough that certain sensors like infrared can tell that they're gas-filled balloons and therefore not trick MS computer systems
