I'm substantially concerned about the policy directions of the space agency. We have a situation in the U.S. where the White House and Congress are at odds over what the future direction should be. They're sort of playing a game and NASA is the shuttlecock that they're hitting back and forth.
Do you remember when you were 10 or 11 years old and you really thought your folks were the best? They were completely omniscient and you took their word for everything. And then you got older and you went through this hideous age when suddenly they were the devil they were bullies and they didn't know anything.
The charm of history and its enigmatic lesson consist in the fact that from age to age nothing changes and yet everything is completely different.
