Circle Planet: Satellites and Radar System

circle planet: Europe needs to be able to analyze what is happening in orbit itself, said Reiter, a German former astronaut, adding that billions must be spent on a radar system to achieve this, according to The Japan Times. We are not currently in a position to get a picture of what is happening up there. Europe has invested billions in its Galileo global positioning satellites, partly to ensure it is not dependent on U.S. systems, but it still relies on the U.S. military to track the hardest-to-spot threats in space. For now, the threat from thousands of dead satellites that continue to circle the planet is manageable, since they are relatively large and easy to track. Almost impossible to spot, a particle moving at high speeds can cause severe damage to satellites costing hundreds of millions of euros or even destroy them, disrupting communications for millions of users. Far more dangerous are an estimated 900,000 particles of over 1 cm in size, and the 130 million that are over 1 mm, the ESA says. (news.financializer.com). As reported in the news.
