Yes, astronauts can fly out here and there as they live in zero gravity in space.
At what altitude does the Earth's gravity no longer have an effect on the astronauts or the space shuttle?
they do-there is no gravity
The zero gravity pen was originally used in space so astronauts wouldn't have to find a pen for example if the zero gravity pen floats then the astronauts would be able to see where a pen is because if the pen did not float then if one of the astronauts needed to write something down they would have to write.
Because there is zero gravity in space
Beacause theres no gravity!
Because there is no gravity.
