"Weight" happens when the attraction of gravity on a mass is resisted, we only FEEL the weight when we are resisting gravity. Weightlessness therefore happens when gravity is not resisted - when you are in "free-fall".
In a space when you are in orbit round the Earth, you are effectively in "free-fall" and therefore as you are not resisting gravity you are weightless (but not massless).
They are in Free Fall.
yes
Technically, as an astronaut is weightless in space, so should a space shuttle!
weightless is just a figure of speech. things in space are just lighter than they are on earth. the space shuttle weighs 220,000pds so in space it might weigh 100,000pds.
They actually are weightless, due to the fact there is no gravity in space. However a sky-diver would say he/she feels weightless, but they are experiencing free-fall.
Yes
yes there are

An astronaut
a space shuttle feels really ruff
To bring any astronaut into space! I hope you like my answer!
That is now impossible. To become an astronaut, you have to be admitted to their Astronaut Training Program.
