The space is full of satellites, space stations, litter, junk, and debris which are in very big number. These objects revolve around the earth in their own orbits. Individual satellites and bodies have their own trajectory, speed and purpose. Due to many incidents and purpose the number of space debris have increased which is causing problems to track them to mitigate collision with other objects. Just as seen in the movie Gravity. These objects are out of control and move with velocity of 30000 Km/hr. This speed give bodies extreme momentum and which on collision with other important objects could cause devastating result which can cause their debris to float and increase the accident geometrically.
US Air force is spending $914M on a new project called “Space Fence” which will be developed by Lockheed Martin. Till today the monitoring system could only capture information of objects which were bigger than 10cm.This project is very much important in this time because the important satellites or objects are always in danger of collision.
The basic structure will include ground based s-band radars which will be in multiple location. It will use digital beaming technology. The space fence will be able to tract big number of bodies and also predict the path or trajectory and thus also predict future incidents like intersection of bodies, trajectory or even collision. This will help to get a prior information so that the path, altitude and position can be changed or maneuvered to prevent such happenings.
The project will make it possible to track and detect small objects in every orbit of the earth. The coolest thing is that it will be able to create a micro fence for high value satellite or object.
This will provide more detailed information on that body to help mitigate any future and current problems easily. The system will be integrated to current space surveillance system for efficiency and it will also have less bandwidth need. The project is to be completed in 2019.
