in other words, enough height allows orbit but hight and orbit are 2 different issues. its not the same thing.
so the term astronaut means if you reached space and not weather you went into orbit or not.
or, you can fly high enough to reach space and be called an astronaut without getting into orbit.
(which is what spaceshipone did)
