When an astronaut in the spaceship is orbiting the earth, the spaceship and the astronaut are in the state of free fall towards the earth with the same acceleration due to gravity. The astronaut does not exert any force on the sides of the spaceship because the down ward acceleration of the astronaut is the same as that of the spaceship. As a result the astronaut feels to be floating weightlessly. Thus the astronaut becomes weightless with respect to the spaceship though the force of gravity at that distance may not zero.
