Satellite lost power could crash on Earth

A large U.S. spy satellite that lost its power could crash into Earth in the next few weeks -- but no one knows where.

The satellite, which no longer can be controlled, could contain hazardous materials, and it is unknown where on the planet it might come down, they said. The officials spoke on condition of anonymity because the information is classified as secret.

"Appropriate government agencies are monitoring the situation," said Gordon Johndroe, a spokesman for the National Security Council, when asked about the situation after it was disclosed by other officials. "Numerous satellites over the years have come out of orbit and fallen harmlessly. We are looking at potential options to mitigate any possible damage this satellite may cause."

I heard of that, but can't imagine which hazardous materials could it be?


It was also sometime ago somewhere in South America (can't remember where exactly) that a strange object fell from the sky and many people died because of breathing some strange material's vapour. It was definitely a military satellite.

The hazardous material is hydrazine, which is used in the maneuvering rockets on some satellites.
