Scientists from Japan and Australia have found a way to put away space debris


Several research groups have developed the concept of the device which can influence an object in an orbit by means of the directed stream of ions or plasma. The Japanese and Australian scientists have found a way to reduce the speed of the movement of space debris and to reduce him from an orbit by means of the plasma rocket engine with two opposite directed nozzles, Scientific Reports reports. To prevent Kessler's Effect (fast increase in quantity of space debris which will prevent a conclusion of new devices in space), several research groups have developed the concept of the device which can influence an object in an orbit by means of the directed stream of ions or plasma. The technological complexity of realization of this idea is that the stream of particles created by the engine will not only make impact on space debris, but also to push the satellite in the return from him the direction because of what this force needs to be compensated by the additional engine. However the group of scientists of Tohoku University has found a way to realize the concept with use of one engine which will influence at the same time an object of space debris and to stabilize the satellite situation. Scientists have created a prototype of the bidirectional plasma engine which has the camera with two open exits. In the camera two tubes for supply of argon and two antennas for his ionization, and outside — two solenoids are located. It is possible to operate draft in both directions by means of change of a configuration of magnetic field or level of supply of gas in each of tubes. Thanks to an opportunity to change a ratio between the plasma streams leaving from the different parties of the engine him it is possible to use in the modes acceleration and braking of the satellite and also removal of space debris from an orbit. We will remind that NASA has found the lost Opportunity mars rover. He managed to be found thanks to the picture made by the space station Mars Reconnaissance Orbiter. The device didn't contact more than two months.
