solutions, relevant pour le commun des mortels de la science-fiction,
sont envisagées par les experts de l'Agence spatiale européenne (ESA),
réunis cette semaine à Frascati, près de Rome.....Cinq cents astéroïdes menacent potentiellement la Terre

Pentagon plans multi-billion dollar project to combat space junk
Later this month the US Pentagon plans to award a massive contract to
one of the two most influential American contractors for a project
that, if all goes according to plan, will be able to identify space
debris before it becomes a threat to the Earth.
Lockheed Martin Corp. and Raytheon Co. are competing for the $6 billion contract to design and construct Space Fence, a radar system that will eventually be able to track large bodies of space matter. The plan is being put into place so that the government can not only better predict the bodies that may come into contact with Earth (such as the asteroid that exploded over Chelyabinsk, Russia, for instance) but also to better protect satellites that could be destroyed while in orbit.

Japan's Launching A Giant Net Into Orbit To Scoop Up Space Junk (video fr)
Something must be done to deal with the estimated 100 million bits of
man-made space junk circling the planet, and Japan is taking the lead.
But can we do? Shoot it with a laser? Invent Wall-E-like robots to
collect it? Nah… let’s just blast a big net into space.
Next month, Japan Aerospace Exploration Agency (Jaxa) will do just that. Having teamed up with a company that manufactures fishing equipment, Jaxa developed a wire net nearly 300 metres long but just a foot wide that will be launched into orbit. Once it’s unravelled, the net will generate a magnetic field that will theoretically attract nearby space debris.

Comment faire le ménage dans l'espace ?
-
Depuis le début de la conquête spatiale dans les années 60, le nombre
de débris présents dans l'espace s'est accumulé de manière
quasi-exponentielle. Aujourd'hui une couverture de poubelle high-tech entoure la terre.
Environ deux tiers de ces objets viennent de l'éclatement d'autres débris spatiaux : que ce soient des explosions ou des collisions. Comme celle de 2009 entre les satellites Iridium et Cosmos à près de 800 kilomètres au-dessus de la Sibérie.
La taille des débris varie de quelques millimètres à la taille d'un bus, n'importe lequel d'entre eux peut abimer un vaisseau estime le chef du bureau des débris spatiaux de l'agence spatiale européenne.
