When entering space, do astronauts feel themselves gradually become weightless as they leave Earth's gravitation pull or is there a sudden point at which they feel weightless?

There is a sudden point at which astronauts immediately feel weightless -- it is the moment when their rocket engine shuts off and their vehicle begins to fall.

Remember, Folks in the ISS are just over 200 miles farther from Earth's center than you are -- that's about 4% farther out, so they experience about 92% as much gravity as you do.

All those pictures you see of people floating around the ISS aren't faked, it's just that the ISS is falling.  The trick of being in orbit is to zip sideways fast enough that you miss the Earth instead of hitting it.
