Golly (yes, I've been using that word a lot lately...telling?!), my son will be twenty six (26) years old by the time we get to Pluto. He's the one that said that he would be 'old' by then.
Of course, I don't think he'll be old by then and he will realize that he's not.
Honestly, I didn't think that we would have had the success we had last year on Mars when I was his age. I thought we had given up on space all together after landing on the moon, yes, due to politics on Earth (Vietnam and whatever else).
Thanks JPL!
