The 60 years we have launched satellites spacecraft and astronauts into space as a result the earth is surrounded by a cloud of debris there are more than 18,000 objects being tracked from the ground at least 750,000 fragments of around the euro in size and millions of pieces that are smaller only 1100 of functional spacecraft and at typical impact speeds of 40,000 km/hr all this material could do serious damage it is not comparable to a gun shot the energy contained in a 1cm particle hitting a satellite at that velocity roughly corresponds to an exploding grenade so the consequences of such a hit mean a satellite failure for larger objects even the satellite destruction and fragment generation which again then has environmental consequences we rarely get to see the effects of space debris but in 1993 during the first Hubble servicing mission a solar array was removed from The Space Telescope back on earth the panel was found to be peppered with damage what space debris experts fear most is a chain reaction where objects break apart in collisions and fragments go on to smash into other objects creating more debris these collisions generate more fragments and these fragments are candidates for new collisions to come so follow on collisions if you like and that the largest fear that we have is that enter in some sort of cascading effect where one collision triggers the next one and this is not anything that will happen within a microsecond like in a movie gravity but this is something that will set in slowly hardly noticeable but unstopable over decades the frequency of collisions might increase without the human influence that is a escenario that might render some regions in space unusable for spaceflight and that would be a disaster for spaceflight. Here ESAC ESA's team tracks space surveillance data and plans maneuvers to keep the agency's operational satellites out of harm's way ESA also ensures that when its spacecraft come to the end of their operational lives they can be taken out of orbit to burn up in the atmosphere plunge safely into the ocean or move to so called graveyard orbits safe from collisions. Concepts are also being developed for missions to capture and remove objects from orbit perhaps using nets or sales the top priority however is to avoid creating a new generation of space debris. Use of services from space is in everybody's interest mitigating the problem space debris should be in everybody's interest as well because we have generated a global problem that can only be solved on a global scale it needs some global response. With hundreds of new satellites due for launch in the coming years ESA is working with its international partners to ensure this orbital pollution doesn't get any worse.

Subtítulos en español: Astroblog Fernando Trucco

La Tierra está rodeada por una nube de escombros. Este material consta de satélites desactivados, etapas de cohetes y otros fragmentos que podrían dañar enormemente a los satélites en actividad.

Entre el 18 y el 21 de abril de 2017, expertos del mundo entero se reunirán en el Centro Europeo de Operaciones Espaciales de la ESA, Darmstadt, Alemania, en la VII Conferencia Europea sobre Desechos Espaciales para discutir los alcances del problema existente, sus posibles soluciones y las conductas futuras que se pueden adoptar para evitar la generación de nuevos detritos.
