Interestingly, NASA couldn’t go green with Curiosity by using solar panels for power. Previous rovers died on Mars due to dust coverage that prevented recharging of the batteries. Curiosity is nuclear powered. Maybe there’s a moral here...
I think the moral is that a vehicle the size of a Buick can’t drive around using solar panels for power. If NASA could have used solar in this case, I’m sure they would have; it would surely be less expensive.
Yes, more nukes, less kooks...
