What happens to satellites when they run out of fuel?

The Short Answer: Two things can happen to old satellites: For the closer satellites, engineers will use its last bit of fuel to slow it down so it will fall out of orbit and burn up in the atmosphere. Further satellites are instead sent even farther away from Earth.

Do satellites get refuel?

While RSGS is focused primarily on satellite repair, refueling is another enormous on-orbit opportunity, since the lifetimes of most satellites are limited by how much fuel they carry.

Why do satellites not need fuel?

Satellite needs no fuel to move around a planet in a fixed orbit because the gravitational force of attraction between the satellite and the planet provides the necessary centripetal force required to revolve around it. A body weighs 63N on the surface of the earth.

What is orbital refueling?

An orbital propellant depot is a cache of propellant that is placed in orbit around Earth or another body to allow spacecraft or the transfer stage of the spacecraft to be fueled in space. It is one of the types of space resource depots that have been proposed for enabling infrastructure-based space exploration.

Why station keeping consumes more fuel in satellite?

This approach is based on the integral over the time of the perturbing forces. In this sense, this integral can be seen as a criterion to select the orbit of the spacecraft. When this value becomes larger, more consumption of fuel is required for the station keeping, and, in this sense, less interesting is the orbit.

Why does satellite does not need fuel to stay in orbit?

Satellite needs no fuel to move around a planet in a fixed orbit because the gravitational force of attraction between the satellite and the planet provides the necessary centripetal force required to revolve around it. An astronaut inside a small spaceship orbiting around the earth cannot detect gravity.
