“It weighs two and a half tons, it is spiraling toward Earth, it carries a deadly fuel called hydrazine and it is on schedule for splashdown in my gazpacho on March 12.”
“And so they have this system that runs on hydrazine, which is kind of a toxic brew of chemicals which creates the, the energy required to control those air surfaces, and on the infrared you can see that think chugging.”
“First of all, it has 1,000 pounds of hydrazine, which is very toxic rocket fuel.”
“In other words, moves the movable flaps on it and it's conducted by burning hydrazine, which is interestingly the same fuel that's in that spy satellite coming up.”
“And what they're saying is that this flash evaporator, which provides cooling for these auxiliary power units, which heat up hydrazine, which is a toxic chemical, essentially.”
“They're run-by hydrazine, which is a toxic substance in and of it's own right.”
“Those auxiliary power units use a substance called hydrazine, among other things, to operate.”
“It would just compound the terrible tragedy if somebody were to be burned or disfigured in some way by hydrazine, which is in particular a very, very volatile ultimately cancer-causing substance.”
“Roughly two-thirds of the spacecraft's weight is in fuels, including hydrazine, which is highly corrosive and toxic.”
“It destroyed an errant spy satellite that still had a full load of a toxic propellant called hydrazine, and was in danger of spilling it over an inhabited area when it re-entered the atmosphere.”
