1. Millions of naturally occurring micrometeoroids and man-made debris orbit the Earth.
2. Orbital debris consists of remnants from previous missions.
3. These items collide and explode creating additional pieces of debris that range from the size of a school bus down to the size of a grain of sand.
4. These pieces of debris may seem innocuous but at hypervelocity speeds they can become killers.
5. The risk in lower Earth orbits (LEO), as well the geosynchronous orbit (GEO) is a growing concern as more satellites are launched and older satellites break apart, leaving debris in these regions;
6. Collisions with debris in GEO can cause significant damage to operational satellites due to their high velocities and the difficulty of maneuvering to avoid them.
