摘要

Meeting Future goals for Orbital Clean-up will require highly efficient satellite and space vehicles that will cleanup the myriad of broken and dead satellites, rocket stages and coolants. In course of time space debris has increasedsignificantly and our earth orbit has become a junkyard, before it expands further, its need of the day to clean themup economically. Without Research and Development of proper design this problem will further increase. This paperfocuses on a design to clean up Space Debris from the Lower Earth Orbit as well as from the Geosynchronous EarthOrbit that intervene in satellite operation and poses great threat to the launch of space crafts, PSLVs and GSLVs. Ourvehicle design will be simple and precise. It would be a Hybrid Chemical-Electric Rocket integrated with a payloadi.e. a kind of Clean up Satellite would be having Electro dynamic Tether propulsion system. It would be launchedinto the LEO using a space launch vehicle from where it will be injected into the orbit. This tethered satellite systemi.e. Space Tether Accumulated-Debris Removal EDT (STAR-EDT) will be using aluminium cable as the tether andwill utilize the ionosphere of earth for charge requirements. During Satellite launch as a part of payload, a RobotCapturing system would also be launched which would be used to capture the space debris and make it attached withtether system. Then tether will be deployed to it and the orbit will be further lowered using the electrodynamic drageffect. Eventually the drag induced by the tethers will reduce the altitude of the debris mass, which would result inincreased effect of the upper atmospheric drag and hence burning it up on re-entry phase. It will speed up thetimetable of the re-entry and help in early clean-up of the space debris. As it doesn't use any propellant so it'seconomical and sustainable to clear large amount of Space debris. To clear the GEO it would be using VASIMR(Variable Specific Impulse Magneto plasma Rocket) system satellite thrusters which will get attached to thegeostationary satellite revolving in orbit and will push them out of the Earth orbit by proving required ΔV needed forescaping the earth gravity totally. They will be left out in the free space, and the GEO will be free for futurecommunication satellites. Overall, this gives an insight and design concept for Space Debris Clean up.
