Saving Space: The Fight Against Orbital Trash | SLICE EARTH | FULL DOC

- Orbital debris is the stuff of nightmares for astronauts. And with good reason - the amount of rubbish circling the Earth has risen exponentially over the last twenty years as space exploration has grown and increasing numbers of satellites are launched.
In 2009, two satellites collided creating thousands of new pieces of debris and sending them into space at phenomenal speeds. This kind of collision could cause a runaway chain reaction, predicted by NASA scientist, Don Kessler in which each collision generates new debris and therefore further collisions.
Everyone involved in space exploration and exploitation is now obliged to track each individual piece of trash circling the Earth in order to move working satellites if they lie in the path of danger. But with around 20,000 catalogued objects in Low Earth Orbit, the risk of collisions is high. Up until recently, little effort has been made to minimize this rubbish and each piece poses a serious threat for the functioning of our satellites and by extension, our activities on Earth.
The time has come to take out the trash. Throughout the world, engineers are coming up with ingenious methods to collect space’s garbage and test their projects: from electro-magnetic cables in Japan, pulverizing lasers in Australia, nets and harpoons in Europe and gas pulverizing rockets in the USA. Star Wars is a long way off … but the war on waste has been declared.

Would love to be a space junk salvager, picking up all the precious scrap, in a batterd old junk ship, like a pikey in space 😂
Lol
Tons of gold just waiting in line to burn up in the earth's atmosphere...
The simple solution is a space dossier, a craft with a kevlar shelled in front that can be tilted to deflect the debris into the earth.
Target practice..
Spare parts 😊
Space debris have certainly become an issue for the United Nations to take action on.If we are to continue space exploration space tugs and other autonomous vehicles will be necessary for us to improve safety for space vehicles around the earth and other planets due to space weather also. Planetary defense also depends on safe access to space .
Sputnik was not the earth's first satellite...
First ARTIFICIAL satellite...
Kevlar magnet impregnated parachute towed behind a drone ship.
It almost work!
I bet that if Space X engineers used the Starships capacity to launch starlink they could design a smaller than starlink (100+ per launch) multiuse garbage men that could make required disposal as part of the Launch cost, affordable and maybe gain on the the detritus in orbit before the death bloom.
Can't you send up some special Henry Hoover's?
Uuuuhh get Elon and Nasa to clean it up...
One part is to bright turn brightness down and the can’t see picture ?😡im pulling my hair out thanks to iPad!
Kessler's Syndrome is inevitable.
One web? Starlink missing.. too outdated!
Has anyone noticed that there has been a decline in the number of UFO sightings since the 1950's and we started littering the near-space around our planet?
The "alien's" don't want to scratch or dent their shiny spacecraft with all the junk we've put up there!😊
Wating for arpoon tests that "will take place in 2020" ... the past future?
Pretty tragic!
How much gold is estimated to be floating around in space junk?
A trivial amount when compared to the cost to put it up there, and dwarfed by the cost to bring it back down intact
couldn't you just burn it up in the atmosphere??
........... maybe laser it?
