Resolution camera with a billion pixels on Gaia telescope will monitor the asteroid capable of working in the earth, the human alerts hazards from space.
CNN reported that the European Space Agency (ESA) will launch the Gaia space telescope into orbit from the space center in French Guyana dated 19/12. It will review the wandering objects in the Solar System, and detailed 3D mapping of the Milky Way.
The company Astrium built on orders of Gaia ESA . Manufacturer description , a billion pixels camera of Gaia can measure the width of a human hair at a distance of 1,000 km , equivalent to determining the size of a person standing on the moon .
When active , Gaia will make you skip 3D Milky , accurate distance measurements from the Earth to about a billion stars . In addition, it will study about a million quasars beyond our galaxy and determine wandering 250,000 objects in the solar system , including asteroids and comets is capable of threatening the planet .
The study asteroids and comets wandering in the solar system help scientists predict catastrophic asteroid similar explosion in Russia in the last 2 months . Gaia , worth $ 1.3 billion , will operate at an altitude of 145 km over sea level . It will record images and orbits of asteroids located between the Earth and the sun , the celestial body that human beings can not be tracked from the ground.
In fact, radiation from the sun creates large blind spots to the system of optical telescopes on Earth. We can not be observed wandering asteroids between Earth and the sun. One of them is a meteor exploding in the sky Chelyabinsk, Russia, made more than 1,500 people were injured Wednesday 15/2 last. The explosion equivalent to 50 U.S. atomic bomb dropped on Nagasaki.
Experts hope that in the course of operation - lasts 5 years - Gaia will discover important things about the star system, comets in the solar system, asteroids or even the very distant supernovae .
