Space debris problem getting worse, say scientists
Scientists have expressed concerns over the accumulating space junk from mankind's six-decade-long cosmos exploration. Travelling at up to 28,000 kmph, junk objects carry enough energy to damage the surface of a satellite or manned spacecraft. Scientists estimate that around 5,000 objects larger than one metre and 7.5 lakh "flying bullets" measuring around one centimetre are orbiting the Earth.
