Abstract :
Space debris in Earth's orbit poses a
significant danger to satellites, humans in space, and
future space exploration activities. In particular, the
increasing number of unidentifiable objects, smaller
than 10 cm, presents a serious hazard. Various
technologies have been studied to remove this Space
debris. This paper discusses the technique of removal of
Space debris from Earth's orbit and bringing it back to
Earth safely. A 2-stage rocket with a unique method of
propulsion system will be sent into space where the 2nd
stage will act as an orbiter comprised of a Robotic arm
covered by a durable Metallic Micro-lattice net. The
mechanism will be used to capture the space debris. This
system will include multiple cameras and sensors for
detecting the debris. Live tracking and identification will
be supported by AI and ML. Also, an active hydraulic
system filled with MRF will be attached between the
sections of the robotic arm. The active hydraulic system
will help/protect the mechanism to resist the impact
force. The fairing will be permanently attached to the
2nd stage just like doors and windows are attached to the
frame which will be reused to protect the system as well
as the debris during re-entry. The hot side of the
thermoelectric pad will be in contact with the inner
surface which will act as a heat sink. The other/cold side
will be directly exposed to the mechanism and debris. As
a result, it will create a cold ambient temperature inside
the fairing keeping the payload safe and cool from the
re-entry heat. Using a modified propulsion system, we
will achieve this mechanism which will also produce
electricity as well as act as an ignition system for the fuel.
When the whole system will be in re-entry phase, thrust
vectors fitted at the body of the 2nd stage carrying the
payload will come in use. It will rotate the system by 180
degrees. Further the thrusters will turn on and will act
as a reverse thruster. This will slow down the freely
falling system. Moreover, parachutes will also increase
the air drag which will further slowdown the speed while
returning and the hydraulic legs fitted at the bottom of
the mechanism will result in minimum impact with the
surface.
