Technically, as an astronaut is weightless in space, so should a space shuttle!
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.
An astronaut has to exert a force on a weightless object in order to move it because in space, there is no gravity to naturally pull or push objects. Therefore, the astronaut must apply force to overcome inertia and move the object.
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.
It actually means that the astronaut is in free fall, and doesn't FEEL gravity. Gravity does affect the astronaut, so the astronaut will still be accelerated towards Earth. However, the astronaut won't feel the gravity.
ahahah nica sorry but i dont answer questions for ugly as people
That is now impossible. To become an astronaut, you have to be admitted to their Astronaut Training Program.
If there is a mistake about space, i will correct it.
when the rockets stop firing, astronauts begin free fall (weightless).
Yes
you sign up for the space aeronautics program and take tests to become an astronaut
