Do you know aerospace rubbish? Do you know its harm? As long as small a small aerospace rubbish can destroy spacecraft easily. And those who make a person adv unimaginably is: In the beautiful earth that we live, be surrounded by rubbish of 10.7 billion aerospace actually!
This is not exaggerate sth just to scare people absolutely, be in today, " rubbish of 170 million aerospace surrounds the earth " the message ascended small gain to heat up search sadly. The insight that yields people is cast from life rubbish to aerospace rubbish.
What is aerospace rubbish
Spoken parts in an opera! Aerospace rubbish is mixed actually the generation process of life rubbish is same, also cause artificially. It is make an object without choose and employ persons around earthly orbital, small arrive by orbiter fragment, Qi Pian, dust, form to whole airship debris greatly.
Did not look down upon these 0 broken broken aerospace rubbish, according to statistic, with the aerospace rubbish that is more than 10 centimeters (have 16 thousand at least) collision may " kill " spacecraft. As the people ceaseless exploration to aerospace. The aerospace rubbish of the bequeath in the universe is 170 million about now.
How does aerospace rubbish arise
At present the generation means of aerospace rubbish shares the following 3 kinds:
It is intended or explode innocently the spacecraft debris of generation. Intended explosion, of the Russia before great majority comes from and American space fight " prepare lessons before class " . Among them before Russia ever had satellitic intercept, explosion test 19 times, brought 500 ～ to aerospace the shiver rubbish that 1000 size differ. Innocently explode, be like between 1973, the United States has 7 rockets to explode on orbit.
2 it is the error with unmindful astronaut. Be like 1982, astronaut covers with tiles · of human relations man lists Bojiefu to be in open " gun salute 7 " when the decompression port that the space stands, because have some huge attraction close to vacuum aerospace place, astronaut people a few bolt inside decompression cabin, gasket and a pencil, inspiratory aerospace, became aerospace rubbish.
The 3 debris that are satellite and rocket. A few satellites that lose effectiveness, still fly on orbit. Although because flight speed is reduced,they are met finally, return aerosphere and with aerosphere attrition burn down, but be afraid after wanting to arrive hundreds of years in a few years. In close ground space, return the leftover share of a lot of float rockets.
The harm of aerospace rubbish
According to not complete count, the aerospace rubbish that there is a diameter to be more than 10cm in aerospace more than 9000, be more than 1.2cf have 100 thousand above, and Qi Pian and solid boost the little grain such as agent grit can count with 1 million plan.
Speed of these aerospace rubbish flight are splitting (6-7km/ second) , the power with their vast under cover: The satellite of aerospace rubbish dash against with a 10 heavy grams, the car when be equivalent to two 100km/ hits each other, the satellite can be hit to wear inside 1.5 seconds or direct smash!
Because this aerospace rubbish is like,stand with the orbiter in running, manned airship or international space barge against, can endanger equipment even the life of astronaut. According to computation, a diameter is 10 centimeters aerospace rubbish, can destroy spacecraft completely. Count the aerospace rubbish of millimeter size, make they cannot continue to work likely.
Aerospace rubbish can clear
Face so austere aerospace environment, aerospace rubbish problem had been become internationally problem. A lot of expert made a lot of attempts to solve aerospace rubbish.
One: Keep clean. Advance the satellite that quits the job other course to go up, lest be the same as the satellite of regular job to produce collision; Bring back the satellite of attaint to the earth with space shuttle, in order to reduce big rubbish of the space. A few scientists put forward, use laser weapon, burn aerospace rubbish directly in aerospace.
2: Exploration control. The system that uses the missile that monitor and emissary satellite will undertake monitoring a few bigger aerospace fragment. The aerospace of the Russia before the United States is mixed detects the network had registered object of 10 thousand aerospace. Everyday about 50 radar, optics or photoelectricity inductor want to have observation about 150 thousand times to the sky, the scientific radar of Germany and United States can explore the object of 2 millimeter size.
3: Mobile radar is in Japan a remote programmed control controls county of hill of Honshu island ridge radar begins the work since April 6, this radar main effect is to dog the shift of aerospace rubbish. This is the world get on the first to be used technically dog the radar with aerospace mobile rubbish, in a few otherer the country is have the aid of will record at radar of for military use or decide aerospace rubbish.
Aerospace rubbish clears robot
Although launch satellitic amount to decrease somewhat, the technology that monitor also rises somewhat, but eliminate aerospace rubbish to remain a very difficult and formidable task. This aerospace rubbish enters the field of vision of people again. Because appeared,be " aerospace rubbish clears robot "
European aerospace total arrange (ESA) announce to this, entitle " ClearSpace-1 " self-destruction robot will be crossed piece history the first pace, sweep the rubbish inside orbit and debris fragment. As we have learned, this robot by research and development of Swiss ClearSpace company, airframe has 4 arms, can be in aerospace adsorptive rubbish.
Self-destruction robot will first grip fragment, rubbish, clear this moorland, return the earth again then, the airframe in the process and rubbish can be in aerosphere combustion dangers. This task will be at the beginning of 2020 begin to prepare, predict to will blast off formally 2025, a series of tests can have in nearer course before this.
