Question
An astronaut inside a small spaceship orbiting around the earth cannot detect gravity. If the space station orbiting around the earth has a large size, can he hope to detect gravity?

Answer

Astronaut inside a small spaceship experience a very small negligible constant acceleration and hence astronaut feel weight less ness. If the space station has too much large mass and size then he can only experience acceleration due to gravity in the proximity of moon or on the moon.
