In closest space is successfully flying on the joint Russian-Germany project "Spektr-RG»
Russia and Germany joint efforts of the storm closest space. Brought probe "Spektr-RG" in the desired orbit by a Russian rocket "proton" successful start held on July 13.
"Spectrum-RG" is a device of complex design, it does not write a lot about it, it is only known that it will observe the sky.
Scientific developments and new technologies in the field of space require financial investments, a joint project of Roscosmos and the DLR Agency has this at its disposal. Germany has money, and Russia has a proven, although already obsolete missile series "proton". Launched the mission "Spectrum-RG" with Baikanur (Kazakhstan).
The missile was prepared a little earlier, but as a result of no big problems, the launch was delayed. The first attempt to launch was carried out on June 21, but then the start failed due to the fact that the batteries of one of the stages were discharged, do not hold the charge well and at the time of start-up were completely discharged. Apparently the rocket "proton" for too long stood idle waiting for flight clearance. In addition, there was another problem, the engineers have identified a malfunction in the acceleration unit. After all the tests and repairs, the launch took place on July 12.
The mission "Spectrum-RG" will go further into space and will be positioned at the point of Lagrange, and since there are several of them, in this case we are talking about the point L2.
At this point the device will be in a stable position, it will be the all powerful gravitational forces to act compensated. This position will allow the device to spend less time adjusting the orbit, as well as to keep a lot of fuel on Board.
Mission "Spectrum-RG" is a very powerful telescope that will observe the distant space and with a high probability will find many new, previously undiscovered, very distant galaxies. Perhaps in the area where will send "Spectrum-RG" will be something interesting, some black holes plan to study more than 3 million. Along the way, the telescope "Spectrum-RG" will also study the stars and pulsars and nebulae. The range of tasks for this device is defined very widely.
On Board the satellite "Spectrum-RG" not even one telescope, and two ART-XC and eROSITA, and both in the x-ray range. ART-XC is less sensitive, but eROSITA will work with energies of about 0.5 to 10 Kev, which is 3-6 times less, that is, eROSITA is largely more sensitive device.
In order to make it clear what the data from the description mean, it is worth saying that 1 electron-volt (eV) is a unit of energy equal to the amount of energy that an electron (a negatively charged particle) receives when it is accelerated from rest due to a potential difference of 1 volt.
Before the device starts to work, it will be calibrated, this process will take about three months.
