Just heard from the news that Iridium Satellite collided with defunct Russian Cosmos satellite creates huge cloud and some 600 space debris.
It is quite a rare event that 2 satellites collided in orbit especially one is the operational US satellite. Communication relay satellite, Cosmos 2251 which was lunched in 1993 and was out of service more than 10 years while Iridium Satellite provides mobile telephone service globally.
I personally feel this story interesting since my work at Iridium Southeast Asia some time before Iridium LLC went Chapter 7 in 2000. Then all the asset including satellite constallation were sold to Iridium Satellite LLC with the value about 10% of the original cost. With its rebranding, the new Iridium service is quite success.
