Great comments, StealthZ.
I'm glad to see space technology of any kind advance into the 21st Century, even if the mock-up is illustrative, only.
To me, space exploration is a collaborative effort of all nations, even if done by the United States and a few others only. After all, America would not be what it would be if not for the contributions of all mankind, who come to its shores.
When I am sick of the tragic nonsense that we see in the world today, with wars and conflict aplenty, I think of the good things that we still have, that we have preserved from better times past, and I relish the hope that all of us can gather together to do what none of us can do alone. We owe it to the future to do what we can to advance the goals of science, technology, and our common purposes.
Godspeed to America's, and the world's, next steps into space. Godspeed, Orion.
