Well, maybe they weren't so simple... But, there is something about them.
So, in 1961, JFK said,
I believe that this nation should commit itself to achieving the goal, before this decade is out, of landing a man on the moon and returning him safely to the earth. No single space project in this period will be more impressive to mankind or more important for the long-range exploration of space and not be so difficult or expensive to accomplish.And, within the decade, we had.
Fast forward to January of 2004. President G.W. Bush announced a renewed focus on manned space exploration. He didn't quite have the eloquence of Kennedy, but, he made it clear:
Inspired by all that has come before, and guided by clear objectives, today we set a new course for America's space program. We will give NASA a new focus and vision for future exploration. We will build new ships to carry man forward into the universe, to gain a new foothold on the moon, and to prepare for new journeys to worlds beyond our own....This week, we made a big step forward. Nearly three years after the President send us on our way, NASA finally announced the contractor -- Lockheed Martin -- to build the spacecraft. Right, steady progress.
Today I announce a new plan to explore space and extend a human presence across our solar system. We will begin the effort quickly, using existing programs and personnel. We'll make steady progress -- one mission, one voyage, one landing at a time.
I think by three years into Kennedy's initiative, we were tearing through multiple missions. This time, we've made an announcement.
At this rate... well, at this rate, none of us may be around to actually see the Orion lift off...
