Earth is often in the firing line of fragments of asteroids and comets, most of which burn up tens of kilometres above our heads. But occasionally, something larger gets through.
This Valentine's Day, look to the skies at night and you'll see stars twinkling, a glistening Moon and perhaps even an orbiting science lab passing by, the International Space Station.
Imagine moving satellites to higher orbits, collecting space debris, and dedicated launches for small satellites. These are the winning entries of ESA's call for ideas on new commercial space transportation services.
Space. The very word speaks of emptiness and isolation. But since we discovered how useful it is to put things up there, space has been getting a little bit crowded.
As an international relations scholar who studies space law and policy, I have come to realize what most people do not fully appreciate: Dealing with space debris is as much a national security issue as it is a technical ...
Talk about space junk.
The Earth is currently surrounded by debris launched into space over several decades. This space junk can collide with satellites, causing damage and creating more debris. To preserve a secure space environment, the active ...
The International Space Station serves as humanity's orbital research platform, conducting a variety of experiments and research projects while in orbit around the planet.
The RemoveDEBRIS satellite has successfully used its on-board net technology in orbit – the first demonstration in human history of active debris removal (ADR) technology.
A satellite with a harpoon, net and drag sail to capture space junk is in orbit and will be tested soon
After almost 70 years of spaceflight, space debris has become a rather serious problem. This junk, which floats around in low Earth orbit (LEO), consists of the spent first rocket stages and non-functioning satellites and ...
