Space Junk

A team of ESA scientists has developed a way to use lasers, special telescopes, detectors, and light filters tuned to specific wavelengths to increase contrast with the sky and accurately track space debris even in broad daylight.

Space debris is a serious problem that won’t be going away anytime soon, but researchers have put forward a novel way to keep things in check, making a case for charging satellite operators an “orbital-use fee” to reduce the risk of collisions.

DirecTV has been granted permission by the US Federal Communications Commission (FCC) to send a damaged communications satellite in danger of exploding due to its severely damaged batteries into an emergency disposal trajectory.

ESA has commissioned the world's first mission to recover a piece of space debris in orbit. At the end of November, the Ministerial Council consortium awarded a service contract to a consortium for the ClearSpace-1 mission to launch in 2025.

Astronomers go to great lengths to find the quietest, darkest corners of the night sky, but a new breed of satellites like those of SpaceX's Starlink project threaten to ruin the views in very damaging ways. And the problems don't end there.

A rare authentic full-scale working test model of the first artificial Earth satellite, Sputnik-1, is up for auction.

​In order to address the problem of space debris, some groups are looking into methods of de-orbiting satellites once their operational lives have ended. One of the latest approaches involves getting the spacecraft to dispense a long strip of tape, instead of using their own propellant.

Remember the garbage-collecting Oscar the Grouch, from Sesame Street? Well, an orbital-debris-gathering spacecraft now bears his name. Known as OSCaR ("Obsolete Spacecraft Capture and Removal"), the semi-autonomous craft is currently being developed at New York's Rensselaer Polytechnic Institute.

Dutch artist and designer Daan Roosegaarde has a knack for raising environmental awareness through spectacular and symbolic pieces of art, and his freshly launched Space Waste Lab might be his most impressive installation yet.

Technology designed to clean up space has captured its first bit of simulated space debris in orbit. Part of the RemoveDEBRIS mission, a balloon acted as a target for the RemoveDEBRIS satellite, which fired a weighted net from a range of seven meters (23 ft)​ and successfully snared the "debris."​

An ESA-funded scientist is developing a magnetic space tug to combat the growing problem of space debris. ​Using cryogenic magnets, the tugs could lock onto derelict satellites and deorbit them before they become a hazard to navigation.

After spending seven months tracking aircraft, CubeSat CanX-7 has started the second phase of its mission, deploying four drag sails to help it fall to Earth faster. The system is designed to demonstrate ways that spacecraft could dispose of themselves post-mission, to help the space junk problem.
