Scientists sounded the alarm Tuesday over the problems posed to space missions from orbital junk – the accumulating debris from mankind's six-decade exploration of the cosmos.Travelling at up to 28,000 kilometers (17,500 miles) per hour, even a minute object impacts with enough energy to damage the surface of a satellite or manned spacecraft.In 1993, monitoring by ground-based radar showed there to be around 8,000 manmade objects in orbit that were larger than 10 centimeters (4.5 inches) across, a size big enough to inflict catastrophic damage, said Holger Krag, in charge of ESA's space debris office.Krag pointed to two events that had amplified the problem at a stroke, creating debris fields with the potential to generate further junk as pieces smashed into each other.
