Newly released documents show that officials knew a satellite falling towards Earth posed no threat

(August 26, 2008) — When the Pentagon ordered a Navy ship to shoot down a crippled US spy satellite last February, it claimed the operation was necessary to prevent a harmful fuel from being dispersed in the atmosphere. At the time, critics charged that the Bush administration was using the toxic fuel as an excuse to demonstrate missile-defense and anti-satellite capabilities.

Now, there is new evidence that the critics were very likely right.

Astrophysicist Yousaf Butt obtained US government documents showing that NASA’s own analysis concluded that the satellite’s fuel tank was expected to burn up completely during re-entry °X even though NASA probably overestimated the tank’s chances of survival.

“Despite its optimistic oversimplifications, the released study indicates that the tank would certainly have demised high up in the atmosphere,” Butt, a staff scientist at the Harvard-Smithsonian Center for Astrophysics, writes in an article for the Bulletin of Atomic Scientists.

Up to now, US officials had refused to release any of the pre-launch analyses regarding the fuel tank, claiming they contained sensitive information.

But Butt says that the newly released documents clearly contradict the official explanation for the shoot-down, which was seen at the time as provocative and risky. The Bush administration had protested loudly when China conducted its own anti-satellite weapons test by shooting down an aging weather satellite in January 2007. One major concern was the amount of space debris generated by the fragmented satellite.

Beyond the stated concern about the toxic fuel, US officials also were probably trying to prevent any fragments of the highly classified National Reconnaissance Agency imagery satellite from falling into the hands of US adversaries.

There were some additional inconsistencies surrounding government officials’ accounts of the operation. In the days before the launch, several US officials warned that bad weather could delay the mission.

But when US News interviewed the captain of the guided-missile cruiser that fired the sophisticated Aegis missile into space, he was puzzled by those reports. “I’m not sure where all of the heavy weather reports came. It was never really heavy weather,” Capt. R. M. Hendrickson said at the time.
