Delta Launch

Delta Launch

It started out as a 10-ton satellite packed with hazardous materials plummeting towards Earth. Then it dropped down to 4 tons, and the materials turned out not to be hazardous. Details are still sketchy, but it now seems clear that the NROL-21 USA-193 satellite that failed just hours after its December 2006 launch is now on its way back down to Earth. Should we be worried?

“Is there a public safety hazard? Probably not. Is there a risk of sensitive technology falling into hostile hands? Possibly. Is this yet another milestone of failure in a surprising troubled intelligence satellite program? Evidently.”

Pike suspects that the story will be back in the news again in a few weeks as the satellite approaches reentry, and its probable landing spot becomes clear.
