Deciphering That Falling Satellite Story

We have to read between the lines on this one, because this event is going to occur but the governmental agencies aren't telling us the whole story.

The Boeing-National Reconnaissance Office imaging radar spacecraft failed just after launch and is coming down probably the first week in March. US 193 is 15 feet long by 8 feet wide and pieces of it will reach the deck. It'll come in somewhere between lat 58.5 N and 58.5 S and that means mainland US is at risk. Onc it reaches about 60 miles up it hits the atmosphere and will take only a half hour to come apart and hit.

That much is certain but the cargo hazards are being fudged. We're being told the rocket fuel hydrazine can pose a hazard and that the craft isn't nuclear powered. That's probably correct but the satellite is most likely nuclear heated, a little factoid buried near the bottom of this Aviation Week story:

"A National Security Council official says that some of the debris could involve hazardous materials. The satellite is not nuclear-powered so there should be no risk from radioactive materials, although some spacecraft do carry tiny plutonium-powered heaters, but these would not pose a debris hazard."

Lo Alamos designed these units to continuously provide a little heat in the deep freeze of space.
"The Light Weight Radioisotope Heater Unit (LWRHU) provided one thermal watt of heat and was used on the Galileo and Cassini spacecraft and Mars Pathfinder Rover. At the heart of this heater unit was a platinum-30 percent rhodium fueled clad containing a hot-pressed 2.67-gram pellet of plutonium-238 dioxide."
Of course these pencil eraser sized pieces of P-238 aren't a debris hazard, they're a health hazard, and there's a good chance they'll vaporize on re-entry creating a terrible cancer risk if this thing hits land.

There's no way of knowing how much plutonium is on board because we'll never be told. But there are probably several of these heaters on the craft and they each carry 2.7 grams of P-238. Also, the satellite may be carrying batteries run on plutonium or enriched uranium, but again we'll never be told.
Ingesting one milligram of plutonium can cause cancer.
A Russian Cosmos satellite broke up over the Indian Ocean in 1983. Traces of it's plutonium were later detected in Arkansas.

This story is straight psy ops cover up. That particular satellite was used to place an atomic detonation on Comet Holmes all in the name of militarizing science of space.
