An explosion was seen in a video documenting the missile launch. US officials say the satellite was shot down on the first try.
The Pentagon is tracking the obliterated remains of a dead spy satellite after a Navy missile connected with a direct hit last night.
Joint Chiefs of Staff Vice Chairman James Cartwright says debris is being tracked over both the Pacific and Atlantic Oceans but it appears none of it's big enough to cause any damage on Earth. General Cartwright says there's an 80-to-90 percent chance the missile hit exactly where it had to: the satellite's fuel tank. It contained 1,000 pounds of hydrazine, which the Pentagon says could have posed a threat to people if the tank had survived re-entry.
Cartwright told reporters this morning that experts are still watching the debris fields and cannot absolutely rule out the possibility that hazardous material will reach Earth.
