RTGs and reaction wheels

Gary — 7/2/2004 3:25:49 AM (archived)

Cassini has RTGs for power and reaction wheels for attitude control. Cassini is built like a '57 Chevy Bel Air. Assuming no operator error (a big assumption), Cassini could last 30 years, maybe longer.

The $64,000 question: Is NASA willing to fund Saturn research for the next 30 years?
