My own American Dream was to serve my country as best I could and make a difference in America - and in the world.
There are many people talking about access to space and, 'How can we make that cheaper? How can we turn that into a Southwest Airlines versus the big airlines?'
Does it make sense for the U.S. to expend hundreds of billions of dollars to mount a new Apollo-style program to return to the moon? Or have we blazed that trail? Shouldn't we help other nations achieve this goal with their own resources but with our help?
I came to dedicate my life to opening space to the average person and crafting designs for new spaceships that could take us far from home. But since Apollo ended, such travels were only in our collective memory.
Going back to the moon is not visionary in restoring space leadership for America. Like its Apollo predecessor, it will prove to be a dead end littered with broken spacecraft, broken dreams and broken policies.
It was interesting to think that the very first liquid ever poured on the Moon, and the first food eaten there, were communion elements.
There's a historical milestone in the fact that our Apollo 11 landing on the moon took place a mere 66 years after the Wright Brothers' first flight.
Space architectures capable of supporting a permanent human presence on Mars are extraordinarily complex, with many different interdependent systems.
When I was a little kid, we only knew about our nine planets. Since then, we've downgraded Pluto but have discovered that other solar systems and stars are common. So life is probably quite prevalent.
One of the major problems with long-term deep space human flight is the requirement for radiation shielding.
