million people space debris. According to scientific estimates, 29,000 large objects at least 10 centimeters, 670,000 large pieces of at least 1 cm and more than 170 million measuring less than one millimeter in turn orbits the Earth. In 2013, are 6,500 tons of “waste of space”, abandoned satellites or pieces of rockets majority who form the bin space.
For four days, scientists, engineers, space operators, industry, academia and policy makers from all major space powers look at the latest advances in research, policy approaches and technical solutions available to prevent the growing risks associated with debris space.
Collisions
debris cascading
“An object 10 centimeters would be able to totally break a spaceship at the time of impact,” said Heiner Klinkrad, head of space trash to the European Space Agency (ESA). “Nothing that a collision with an object one centimeter to the classic speed of 50,000 km / h would release energy equivalent to that grenade,” he said.
recent years, 250 explosions were recorded, releasing yet more debris. The risk of chain reaction is high. “We talk about Kessler syndrome,” says Heiner Klinkrad. “That is to say, collisions with debris cascading render unusable some orbital regions in the long term.” The risk is that the multiplication of the debris makes a part of the space unusable.
However, the difficulty of finding solutions lies not only in the technical capabilities and costs to eliminate waste but also in the resolution of questions of international law and property debris.
