wouldn’t all the fuel burn up on re-entry. That would make a nice view coming back down to earth.

I think the fuel is radioactive!

“..wouldn’t all the fuel burn up on re-entry.”

Don’t you know that that would only add to the CO2 level in our atmosphere causing an increase in global warming?

Depends on whether the fuel is *merely hazardous* [like the anhydrous hydrazine emergency geneerator aboard F16s] or really hazardous like that aboard the former Soviet Union's radar ocean reconnaissance satellites, AKA RORSATs.

Which is aboard our naughty NRO launch 21 bird, and do the Future Imagery Architecture program cameras aboard utilize a nuclear radioisotope thermoelectric generator as their powerpack? Sorry, that info's classified.

However, you might want to try some websearching for NORAD Catalog Number 29651 In which case, you'll come across *this.*
