Hit!

We successfully engaged the broken satellite with a missile shot from Lake Erie:

At approximately 10:26 p.m. EST today, a U.S. Navy AEGIS warship, the USS Lake Erie (CG-70), fired a single modified tactical Standard Missile-3 (SM-3) hitting the satellite approximately 247 kilometers (133 nautical miles) over the Pacific Ocean as it traveled in space at more than 17,000 mph. USS Decatur (DDG-73) and USS Russell (DDG-59) were also part of the task force.


According to this article, the satellite bits should safely reenter the atmosphere without harming anyone or leaving valuable pieces intact:

Cartwright said experts were still watching the debris fields and he could not yet rule out that hazardous material would fall to Earth. But he said that as of Thursday morning, debris had only been seen in the atmosphere — and none had been detected surviving re-entry. He indicated that debris appeared unlikely to pose a problem.

"Thus far we've seen nothing larger than a football," he said, referring to debris in the atmosphere spotted by radars and other sensors.

The military concluded that the missile had successfully shattered the satellite because trackers detected a fireball. Cartwright said it was unlikely that the fireball could have been caused by anything other than the hydrazine in the tank.


Good job, Navy.
