The head of the press service of Roskosmos Vladimir Ustimenko told about the issue that caused the postponement of the launch of the carrier rocket "proton-M" space astrophysical Observatory " Spektr-RG ".
"The problem can be formulated as follows: reducing the pressure in the tank of the second stage of the launch vehicle because of leakage in pipeline pressurization of the tank," said Volodya in the process of call.
He also confirmed that startview involved in correcting the problem, will present the awards." The appropriate order in preparation ", - said Volodya.
Launch of "Proton" was postponed twice. First start scheduled for 21 June, but because of the discharged battery "Spectrum" missile had to return to the Assembly and test building. The start was postponed for July 12, but the "Roscosmos" any comments to the rocket, and It was postponed for Another day.
in the end, "proton-M "with" Spectrum-RG " started From Baikonur cosmodrome at fifteen: 31 GMT 13 Jul. Ten minutes after the start unit for acceleration of DM-03 separated from the third stage of the rocket, and then successfully brought the Observatory into the target orbit.
Space Observatory " Spectrum-Roentgen-Gamma ", international Russian-German project. Its goal is the development of an orbital astrophysical Observatory for studying the Universe at x-ray wavelengths. Using "Spectrum-RG" is expected to make a map of the visible Universe, where the expected observed all sufficiently large clusters of galaxies.
The Observatory " Spektr-RG ", built at NPO Lavochkin, includes two telescopes: eRosita, created by the German society extraterrestrial physics Institute of the max Planck and ART-XC, developed by the space research Institute and manufactured by the Russian research Institute of experimental physics in Sarov.
Now the "Spectrum" the flight working the Lagrange point L2 (the point in space where balanced gravitational influence of the Sun and Earth), located one million miles from Earth. According to the calculations of the Roscosmos, it will take 3 months. During this period of time are to test the efficiency of the telescopes and to conduct astrophysical observations.
in the next four years, the Observatory needs to create eight complete surveys of the celestial sphere. Two and a half years will be devoted to point observations of objects in the Universe according to the applications, world scientific fraternity.
