New Ideas! China Wants To Use Huge Lasers To Clean Up Space Garbage

Jan 25.2018
According to foreign media reports in January 15th, there are about more than 20 thousand orbital debris around the earth, which are enough to harm satellites and spaceships. It sounds like a plot in science fiction, but Chinese scholars have boldly put forward the idea that we should use huge lasers to crush these fragments. According to an article published by Air Force Engineering University in Xi'an, space based lasers can smash the space junk into smaller pieces, in order to reduce the potential harm of these wastes.

Spaceships and satellites are now under threat from these more than 20 thousand orbital debris. How did these fragments come into being? The research found that these fragments came from old satellites and abandoned multistage rockets. Of course, there are still some breakages, corrosion and collisions coming from aircraft.

At that time, Nicholas Johnson, chief scientist of orbital debris, said in a statement, "every piece of debris is likely to seriously disrupt or terminate the operation of vehicles in near earth orbit." NASA has also predicted that there are more than 1 million orbital debris around the earth, the size of which is less than 0.4 inches (about 1 centimeters). And the debris is revolving around the earth's orbit, which will seriously threaten future astronauts and aircraft to perform space missions.

The Chinese research team simulated a laser station and carried out a simulation experiment that showed that the laser would help us to remove the earth's orbit. The research team said that the simulation experiment provides a theoretical basis for the future use of space-based laser stations, and also provides a reference for further using space based lasers to remove space debris.
