problem is, although they work better in space, they also get damaged / corrode / basically lose functionality over a relatively short period of time because of the harsh environment.

that's why, for instance, XM radio has had to already launch replacement satellites up because their original sat's only had an expected lifespan of about 10 years

I would think it's more of the orbit decaying than the satellite itself but both probably happen in different circumstances.

I don't think it's really nuclear, as in fission or fusion, it's the heat from a decaying radioactive substance.


They have a term for that. It's "Nuclear". ;)

Seriously, they do use nuclear power, but it is different than a nuclear power plant.

In fact, you can find info on RTG's in the Wikipedia article for Nuclear Power.
