Description

NASA celebrates 25 years of work unique space telescope "Hubble" by means of which many secrets of the Universe are solved . The world's first space telescope of this kind was launched April 24, 1990 aboard the space shuttle Discovery. With the help of "Hubble" made such images of galaxies, which previously could not even dream of. The primary mirror of the telescope "Hubble", only 2.4 meters in diameter, polished to perfection in the range of 10 nanometers and is the most accurate surface ever made by humans. This accuracy allows to see unusual objects for many millions of light years from Earth. For a quarter century, "Hubble" transmitted to Earth over one million observations of the total volume of data more than 200 terabytes. They became the basis of more than 15,000 scientific publications of the stars and galaxies. However, for many years, "Hubble" is not under repair, maintenance of this unique telescope produced only during spacewalks with a space shuttle type , which now do not fly. There were carried out four expeditions "shuttle" on service of the telescope "Hubble". There was a thought to attract further service "Hubble" astronauts to the ISS, but with the current deterioration of US relations with Russia this development already looks as far away as the galaxies themselves which photographs "Hubble".
