    U.S. satellite to monitor space debris

    The first satellite, which specializes in monitoring space debris launched Thursday by the U.S. Air Force. The mission is critical, as human objects gyrofernoun planet is now threatening tens of thousands and space operations.

    Satellite SBSS (Space-Based Space Surveillance, Monitoring of Space from Space) is equipped with a camera that sees in visible light and can be rotated to have a wider field of vision. We collect 400 000 everyday observations, which will be broadcast continuously at monitoring stations.

    The new body will have free view Heaven on Earth, in contrast with existing systems faced serious constraints. The U.S. Air Force today is based on a network of terrestrial telescopes and radar, to monitor about 1,000 active satellites and space debris, 20.000.

    But ground-based telescopes are useless when the sky is clear, and many of the radar is powerful enough to detect the satellites in the so-called geostationary orbit about 36,000 km from the planet's surface.

    The Air Force monitors objects with length of 10 cm, which could damage satellites or even the International Space Station in case of a direct hit.

    Most of these objects are human, the more natural particles in Earth orbit are usually quite small.

    The danger from space debris is not just theoretical: at least two accidents have been recorded in the last 15 years: In 1996, a French satellite was damaged by a stray missile component, while in 2009 a decommissioned Russian satellite collided with a U.S. satellite communications active over from Siberia.

    The issue had come to the public in 2007, when China successfully tested a missile designed to destroy satellites. The test was aimed at an old Chinese satellite, which disintegrated and released the 2400 fragments of diameter greater than 5 cm.
