The largest garbage garbage dump on Earth might be in distance .
In low Earth sphere — the space around our satellite up to about 1,200 mile ( 2,000 klick ) in height — more than3,000 defunct satellitesand tens of million of small slice of dust clatter around the atmosphere . And each is moving at ten of thou of miles per hour . Sometimes , two freehanded pieces of this so - called " outer space junk " clangor into each other , fragmentise into yet more junk , each one a petite bullet of rubbish that could critically damage satellites and space vehicle .
An artist’s rendering shows the ClearSpace-1 satellite using its robotic arms to capture the conical piece of space debris called Vespa.
It ’s a real job . Now , theEuropean Space Agency(ESA ) has announced plans to tackle that job , using robot hugs .
In a mission have it away as ClearSpace-1 , ESA will launch an experimental , four - armed golem to grasp a defunct satellite in its clench , hug the object close , then last drag it on a kamikaze dive into Earth ’s atmosphere — destroying both gadget . The wallop of absent one dead satellite from arena is a routine like have one bucketful of body of water out of Lake Superior . But mission officialssaid in a statementthat they hope the project will pave the agency for the new regime of outer space - debris cleanup that our ambience urgently needs .

" The infinite debris outlet is more pressing than ever before , " Luc Piguet , founder and CEO of ClearSpace , the Swiss junk - removal startup partnering with ESA on the foreign mission , said in the financial statement . " Today , we have nearly 2,000 resilient satellite in infinite and more than 3,000 betray single . And in the coming class , the number of satellites will increase by an parliamentary procedure of order of magnitude , with multiplemega - constellationsmade up of hundreds or even thousands of satellites planned for low Earth compass . "
The need for a cosmic " towage motortruck " to remove defunct satellite and make room for new I is pressing , Piguet said .
Scheduled to launch in 2025 , the ClearSpace-1 mission will test its automatic hugging muscularity on a midsize opus of junk call Vespa , which ESA ’s Vega catapult deposited about 500 knot ( 800 kilometer ) above Earth in 2013 . That cone-shaped chunk of debris weighs about 220 lbs . ( 100 kilograms ) , making it a comparatively light and comfortable target for capture on the automaton ’s debut mission .
After that capture , Vespa and the robotic garbage collector will make a assure yet fiery descent into Earth ’s atmosphere . The price of this one - time delegation is reckon to be about $ 133 million , according to The Guardian .
Whether the commission proves to be a toll - effective elbow room of clearing Earth ’s orbital trash remains to be discover . In the meantime , various other nation and federal agency have proposed other detritus - remotion methods , includingdeploying tiny netsand usingsatellite - mounted lasersto clap bit of space detritus into the atmospheric state . sincerely , it ’s an exciting clip to be in the infinite refuse collection byplay !
