NASA to measure debris floating around space station

It is estimated 7.5 lakh "flying bullets" measuring around one centimetre orbit the Earth, which pose risk to manned missions. The one-square-metre Space Debris Sensor (SDS) would be launched via a SpaceX cargo mission on December 4 for mounting outside the ISS.
