A startup wants to use foam to pull junk from space

Popular Mechanics quoted John L. Crassidis, SUNY Distinguished Professor and Samuel P. Capen Professor of mechanical and aerospace engineering, in a story on a Russian startup that's spraying space junk with polymeric foam that will then sink safely and burn up in Earth’s atmosphere.

Foam may sound weird, but it also may just might work, says  Crassidis. “It works on the well-known process of increasing a debris surface area in order to increase its drag, and thus make it re-enter the Earth’s atmosphere and burn up faster.”
