Space junk is on the rise. Scientists have come up with a strange way to clear it

不久的将来,一定会有合适的清理太空垃圾的方案出台并变成现实。

More than 50 years have passed since the birth of the first space junk. So researchers have come up with some creative ways to clean up the space junk.


On March 25, according to science daily website reported that since October 4, 1957 the Soviet union successfully launched its first man-made earth satellite, ushered in the age of the human space, as well as the space has sent the first man-made waste. Since then, space junk has grown with each passing day in the history of human space. So researchers have come up with some creative ways to clean up the space junk.


Now, let us NASA Johnson space center orbital debris program of bureau director and chief scientist Nicholas Johnson is relatively satisfactory a crazy ideas is clear space junk - a diameter of 1.6 km of huge Non stretch leisure bubble (Non - Expanding Recreational terms, NERF), the huge bubble ball can be used to collect space junk. When small pieces of space pass through the bubble ball, they lose energy and quickly fall to the earth's surface. However, this scheme also has shortcomings, foam ball can itself quickly out of orbit, because light weight relative to its size, so it might accidentally hit the spacecraft in the running, it will be very bad thing.


In addition, the scientists designed three more creative schemes, including:


1. Laser transmitter


Lasers are fired from the ground or from space, pushing space junk into orbit closer to earth and speeding it down under the influence of earth's gravity. But the downside of such an idea is that it costs too much, laser launchers are expensive and can hit only a limited number of targets.


Space junk collection vehicle


The space junk recovery vehicle will be able to collect and encapsulate large chunks of space debris at designated locations in orbit and then transport them to orbit closer to earth. The garbage collector can also collect whole pieces of old rocket debris. However, the problem of the subscheme is that the cost is too high and the operation is complex.
