Space Junk

A space-debris-clearing drag sail developed by Purdue engineers called Spinnaker3 that is large enough to pull a spent rocket booster out of a 400-mile orbit to safely burn up in the Earth's atmosphere will be put to the test next month.

Private orbital debris removal company Astroscale has demonstrated its magnetic capture system that is designed to tackle the problem of space junk, with its ELSA-d servicer satellite managing to capture a simulated piece of space debris in orbit.

The ISS was forced to make an emergency course correction to avoid an unidentified piece of space debris earlier this week, an incident that highlights the dangers posed by the thousands of tonnes of disused satellites and rockets orbiting the Earth.

Given how many satellites and bits of orbital debris are now orbiting the Earth, it's becoming increasingly important to keep track of where they all are. A new telescope system allows space agencies and other clients to do so – even in broad daylight.

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.
