So "Weight = mass x gravity" has been pummelled into my head with vigorous fervour.
So I agree with you that, in orbit, we experience "free-fall counteracted by velocity" and the true "weightlessness" only exists, in theory, in interstellar space.
And I bloody wish that mankind would send a probe to confirm or deny it instead of invading another stupid place full of brown people, or refinancing bankers with gambling habits.
I think the F35 or the bailout has already cost multiples of the total budget NASA or ESA budget since their inception.
So as much as I like fancy jets and fat cat bankers, I think that we, as a race, should strive a bit more for science and a bit less on dick waving and pocket filling.

The common misconception is that they are experiencing 'zero gravity'.
Zero-gravity is essentially impossible as long as there are atoms in the universe - Anything with mass creates a gravitational field.
As already described, the effect is due to being in a state of freefall.
