The missile launched to destroy the tank was designed to counter other incoming missiles so precision may be an issue. The Pentagon said in a statement: “Confirmation that the fuel tank has been fragmented should ... Read More

After its launch in December, a U.S. spy satellite will have to be shot down before it starts falling next month.

Hydrazine is a compound similar to ammonia ... Read More
