that a very vague vision; a bunch of words with no actual goals.

It used to be "land on the moon" - they've done that. A space telescope - they've done that many times. What is their goal now because I don't know and most Americans don't know but NASA certainly want us to pay millions for their toys. Set a goal, ask for funding. At this point, NASA shouldn't even be ran but the government. Run a patreon and have citizens pony up the money. Those who support NASA can fund NASA.
