For decades, space experts have worried that a speeding bit of orbital debris might one day smash a large spacecraft into hundreds of pieces and start a chain reaction, a slow cascade of collisions that would expand for centuries, spreading chaos through the heavens.

In the last decade or so, as scientists came to agree that he number of objects in orbit had surpassed critical mass – or, in their terms, the critical spatial density, the point at which a chain reaction becomes inevitable. They grew more anxious.

Early this year, after a half century of growth, the federal list of detectable objects (four inches wide or larger) reached 10,00, including dead satellites, spent rocket stages, a camera, a hand tool and junkyards or whirling debris left over from chance explosions and destructive test. So our billion dollar of satellites are at risk.

 Answer:

Debris accumulated from a variety of space programmers have reached a critical spatial density, which poses risk to satellites these debris could inevitably kick start a very long chain event of destructive collision.
