Solution:
The spaceships are designed in a way that they are not affected by external forces, including the Earth's gravitational pull. These vehicles that carry the astronauts and pieces of equipment for space research orbit outside the Earth's atmosphere. They are outside the Earth's attractive space. Since they move around the Earth, the gravitation does not affect these satellites. However, some satellites are involved in communication and navigation and orbit within the gravitational influence region of the Earth.
