Disabled Spy Satellite Threatens Earth

Sunday, January 27, 2008; 1:30 AM

WASHINGTON -- A large U.S. spy satellite has lost power and could hit the Earth in late February or early March, government officials said Saturday.

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. It was not clear how long ago the satellite lost power, or under what circumstances.

"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."

He would not comment on whether it is possible for the satellite to perhaps be shot down by a missile. He said it would be inappropriate to discuss any specifics at this time.

A senior government official said that lawmakers and other nations are being kept apprised of the situation.

The spacecraft contains hydrazine _ which is rocket fuel _ according to a government official who was not authorized to speak publicly but spoke on condition of anonymity. Hydrazine, a colorless liquid with an ammonia-like odor, is a toxic chemical and can cause harm to anyone who contacts it.

Such an uncontrolled re-entry could risk exposure of U.S. secrets, said John Pike, a defense and intelligence expert. Spy satellites typically are disposed of through a controlled re-entry into the ocean so that no one else can access the spacecraft, he said.

Pike also said it's not likely the threat from the satellite could be eliminated by shooting it down with a missile, because that would create debris that would then re-enter the atmosphere and burn up or hit the ground.

Pike, director of the defense research group GlobalSecurity.org, estimated that the spacecraft weighs about 20,000 pounds and is the size of a small bus. He said the satellite would create 10 times less debris than the Columbia space shuttle crash in 2003. Satellites have natural decay periods, and it's possible this one died as long as a year ago and is just now getting ready to re-enter the atmosphere, he said.

Jeffrey Richelson, a senior fellow with the National Security Archive, said the spacecraft likely is a photo reconnaissance satellite. Such eyes in the sky are used to gather visual information from space about adversarial governments and terror groups, including construction at suspected nuclear sites or militant training camps. The satellites also can be used to survey damage from hurricanes, fires and other natural disasters.

The largest uncontrolled re-entry by a NASA spacecraft was Skylab, the 78-ton abandoned space station that fell from orbit in 1979. Its debris dropped harmlessly into the Indian Ocean and across a remote section of western Australia.

In 2000, NASA engineers successfully directed a safe de-orbit of the 17-ton Compton Gamma Ray Observatory, using rockets aboard the satellite to bring it down in a remote part of the Pacific Ocean.

In 2002, officials believe debris from a 7,000-pound science satellite smacked into the Earth's atmosphere and rained down over the Persian Gulf, a few thousand miles from where they first predicted it would plummet.

Hola, la noticia también la podéis encontrar en español AQUI

Me entere de la noticia cuando estaba escuchando carrusel deportivo y tenían liado un cachondeo con el satélite... , me creía que estaban de guasa. Pero cuando he visto esta mañana la noticia

Saludos.

llevará disco duro con informacion sobre ellos ?

Molaría verlo atravesar la atmósfera en directo.

A ver que ocurrirá, no será nada grave, estrá todo calculado para cuando caiga, si esque cae en sitio peligroso.

A lo mejor tiene que salir el equipo dedalus a arreglarlo para que las cabezas nucleares no exploten al entrar en la atmosfera ( Space Cowboys )

Todo un lujo sería poder ver la enbtrada en a atmósfera de ese satñélite que por lo que parece está completamente fuera de control ya que piensan incluso desintegrarlo en trozos pequeños con un misil.

En el enlace que hay en este hilo a pa página en español ponen: El mayor reingreso de una nave que se ha producido, fue en 1979 con la nave espacial de la NASA Skylab, de 78 toneladas. Sus restos cayeron en el océano Índico sin causar ningún daño.
Yo creo que la estacion MIR era más masiva que el skylab pues tenia una masa de alrededor de 135 Toneladas.

Me temo que uno era mio, sorrrrrry

Hola.

Creo que el problema en este caso no es la masa del satélite.
Lo ser el mayor reingreso desde el Skylab, supongo que se refiere solo los satélites de EEUU y la MIR era sovietica pero bastante más masiva. Estos informadores desinformados,....
Y lo de destruirlo con un misil, debe de ser que al tratarse de un satélite espía, no querrán que esa tecnología y la información que pudiera contener caiga en manos de sus enemigos. Como apunta pablox.
De todas formas estoy con nacho, poder ver la reentrada seria un lujazo.

Saludos
