A rocket carrying two experimental satellites to track enemy missiles was launched Friday from Cape Canaveral Air Force Station, Fla., NASA officials said.
The $1.5 billion Space Tracking and Surveillance System Demonstrator is designed to spot incoming missiles early in flight and signal interceptors to destroy them.
The satellites have power-generating solar wings and are equipped with infrared and visible sensors to spot missile launches and track attacks, NASA said.
The satellites, built by Northrop Grumman and Raytheon, are to circle the Earth within the Ballistic Missile Defense System.
The two-stage rocket aimed for a 730-nautical-mile circular orbit inclined 58 degrees to the either side of the equator to release the tandem demonstration satellites for the Space Tracking and Surveillance System, a $1.5 billion project known as STSS Demo.
The two craft, weighing nearly 5,000 pounds at launch and each having pairs of power-generating solar wings, are equipped with infrared and visible sensors to spot missile launches, track the vehicles through space and observe the entry back into the atmosphere. By working together from separate vantage points in low-Earth orbit, their imagery will combine to provide 3-D tracking of objects.
