The cost of space debris: In-space collisions increasingly likely

With hundreds of satellites launched every year, in-space collisions and the creation of fast-moving fragments of space debris—or 'space junk'—are becoming increasingly likely, threatening our continued human and technological ...

Lasers learn to accurately spot space junk

Chinese researchers have improved the accuracy in detecting space junk in earth's orbit, providing a more effective way to plot safe routes for spacecraft maneuvers.

How a startup plans to clean up space

Since 2012, engineers at EPFL's Space Center have been hard at work on a new junk-clearing satellite to capture debris orbiting the earth. The team has now shifted up a gear, founding a company called ClearSpace to pick up ...

Traveling into space – safely, quickly and cost-effectively

Low Earth orbit increasingly resembles an overcrowded junkyard. Disused satellites, burned-out rocket stages and thousands of pieces of debris produced by collisions – all these things pose a threat to infrastructure in ...

China has a plan to clean up space junk with lasers

Orbital debris (aka. space junk) is one of the greatest problems facing space agencies today. After 60 years of sending rockets, boosters and satellites into space, the situation in the low Earth orbit (LEO) has become rather ...
