Old satellites would after retirement could serve as a defense against asteroid, since they could detect them, redirect them if they move towards Earth.
The project was created under the umbrella of the Airbus company, and the concept got its name Fast Kinetic Deflection (FastKD). Telecommunication satellites in geostationary orbit, at about 36,000 kilometers from Earth, synchronized with the speed at which our planet rotates around its axis. They are usually large in size, and are the smallest size of the average bus. It weighs between four and six tons, so thanks to that can affect the asteroid’s trajectory. However, experts point out that an asteroid with a diameter of about 300 meters could be redirected if ten such satellites acted on it.
Airbus chose the available technology for one reason: astronomers still can’t detect asteroids until they get close to Earth, so it’s convenient that defense systems are already in space. It is pointed out that apocalyptic scenarios are being considered because it is very likely that they will happen one day, probably in the distant future.
