Accumulating space garbage – Jeonbuk Provincial Daily

Space junk encompasses everything that humans throw into space.

▼ Among the artificial satellites launched by mankind, debris such as multi-stage rockets that have expired or are no longer functioning or have been abandoned are drifting in Earth’s orbit at a speed of 8 km/s. In addition, small items such as various tools that astronauts missed while swimming, screws that fell off satellites, and even pieces of paint are space garbage.

▼ Space garbage is 7-8 times faster than bullets, so even a 10cm diameter of garbage can destroy an artificial satellite. There are about 26,000 such fragments in space, and it is said that there are 170 million fragments less than 1 cm in diameter from a grain of sand with the power to puncture a space suit. Space debris poses a great threat to the safety of astronauts as well as various communication satellite navigation systems and artificial satellites operated for earth observation.

▼ On the 16th, the Russian Ministry of Defense conducted an intercept test of destroying a floating spy satellite with a missile since 1982, and the United States and other western countries strongly criticized the fragments that were generated as a threat to the activities of the spacecraft.

▼ As space activities become more active in the future, international disputes over space debris are expected to intensify. It is known that not only Russia but also the United States, China, and India have been experimenting with shooting down their own satellites that have already reached the end of their lifespan. Wherever people go, there is garbage. As long as humans advance into space, garbage is inevitable. Space debris is getting worse and worse. Isn’t this the seed of conflict between countries? It is an issue that cannot be neglected.
