The amount of debris orbiting the Earth has reached "a tipping point" for collisions, which would in turn generate more of the debris that threatens astronauts and satellites.

Nasa needs a new strategic plan for mitigating the hazards posed by spent rocket bodies, discarded satellites and thousands of other pieces of junk flying around the planet at speeds of 28,164km/h, the US National Research Council said in a study published yesterday.

The council is one of the private, non-profit US national academies that provide expert advice on scientific problems.

Orbital debris poses a threat to the approximately 1,000 operational commercial, military and civilian satellites orbiting the Earth - part of a global industry that generated $168 billion in revenues last year, Satellite Industry Association figures show.
