Space.com : Two low-Earth-orbiting demonstration satellites successfully tracked a ballistic missile launch through all phases of flight. Such “birth-to-death” tracking has never been done before from space, according to Doug Young, vice president of Northrop Grumman Aerospace Systems, which built the satellites. Northrop has built three such satellites for the US Missile Defense Agency, which aims to spend $1.34 billion on the Precision Tracking Space System between 2012 and 2016.
