Anyone who’s seen the Oscar-baiting visual spectacle that is Gravity, starring Sandra Bullock and George Clooney, knows in vivid 3D detail just how dangerous space debris can be. Leaving aside the scientific veracity – or lack thereof – of the movie, the cluttered environs of our immediate cosmological neighbourhood is an issue that is being taken quite seriously by the countries of our little planet, since most of the crafts up there are the satellites we need for everyday services like communication, navigation and entertainment.The problem isn’t so much the number of operational satellites that are needed to feed our voracious appetite for satellite television, instant communication and the knowledge of just where the nearest Starbucks is and how to get there. It’s the defunct satellites that are no longer useful, but are just hanging around in Earth’s orbit with nowhere to go.In recent years, space agencies have gathered together to form an Inter-Agency Space Debris Coordination Committee and NASA has handbooks,It is the latest way in which Syrians opposed to the government feel led gu10 factory

. The first of its kind in the world, the gossamer sail system is an aerodynamic drag technique that’s designed to take down telecoms satellites when they reach the end of their life. The sail is ultra-lightweight and extremely compact, taking up a space of just 15x15x25cm on the satellite and weighing only 2kg. It can deploy in minutes, expanding to 5m2, creating enough drag to pull a craft of up to 700kg out of orbit to burn up in the high atmosphere.
