how are satellites powered?

Sorry -last question for my final review.. how are satellites powered powered (the ones put up in space by Nasa, not directV)? I figure a combination of solar and something else but I can't find any solid info.. I'm talking historically speaking and not what the current/cutting edge tech is..

Thanks!

Tried google - too many results!
 
Solar with a battery(s) that gets recharged.

Nuclear is an option that no-one will admit to.

There are also gas tanks for manuvering. The jets are directed by electrical control.

Thanks guys.. I figured that it was solar but one site mentioned nuclear power and confused the hell out of me.. Thanks!

That's just what they want you to think. I can't reveal too much, but there are many industries actively suppressing the use of mutated ferrets are a power source. Can you imagine how many industries would be hurt if every car was powered by a mutated ferret?
Mutated ferrets have most of the oil company executives shaking in their shoes.

We told you to keep your mouth shut about that and you'd be spending a happy christmas with your family. But no, Mr Tweak, you had to be the brave one.

We'll be in touch.

 
Those big flat "wings" coming out of them provide them with solar power. Either on-board or ground based guidance keeps them pointing at the sun so that they get the most power they can.

there have been and are satellites powered by radio isotope systems, i remember about 20 years ago a satellite with a nuclear based power system crashed in canada
 
silly people... don't you know all that space footage is just faked in a studio? Next, you'll be telling me that man walked on the moon...

 
Attempt #2 at humor/wrong answer (aka 1 thread, 2 nefs)

Magnetically charged particles are streaming through space from the sun. Normally, you move a wire through a magnetic field to create electricity... in this case, the field is moving past the wire. So, they just need to send up a circuit and it runs automatically without any power supplies... the ions going by simply cause current to flow in the wires.

*note: didn't they actually try this on the space shuttle twice, but both times there were mechanical problems... they were going to use the earth's magnetic field?
 
solar. The main issue with maintaining a satellite for extended periods of time comes down to degradation of the solar cells in the space environment.
