The starry sky shines not only in the colors of visible light, in the infrared and in the ultraviolet, but also in the light of X-rays, which is blocked by the earth's atmosphere. Despite all the space observatories that have been started, there is still no complete sky catchment in the average radiography radius, between 2 and 10 keV. Rosat provided the photos of the area below. Satellites like Chandra or XMM-Newton observe only individual objects and do not provide a complete overview. Already in June Spektr-RG was leading a rocket of protons on the launch pad. On Saturday, it managed to reach Librationspunkt L2 at 1.5 million kilometers away.
Since the fall of the Soviet Union, it has been the first successful launch of a Russian scientific mission outside Earth's orbit. The last two important missions, Phobos-Grunt is Mars 96 Both failed due to a startup program malfunction. The start message was successful and the separation of the observatory was also received in Germany with a corresponding relief, where one of the two main payloads was developed. Statistically, only 9 launches out of 10 of the proton rocket were successful.
The mission's history dates back to 1987, when the Soviet Union sought the scientific uses of the 72Kh6 military satellite used to monitor ballistic missile launches from a highly elliptical orbit. It had to be precisely focused on the objectives, providing a good platform for space telescopes: Spektr-RG had already been planned as an international mission, involving over 20 partner countries throughout history, including Germany.
15 different tools should be able to make panoramas and detail shots. Spectrometers should perform more accurate analyzes and detect other gamma-ray burst detectors. Originally the departure was scheduled for 1993. But the financial problems and the collapse of the Soviet Union delayed the project in favor of Mars 96.
After the failure of Mars 96 Spektr-RG should be placed at the top of the budget for Russian space research. But after the national bankruptcy of 1998, the state practically did not make funds available. It is said that the international partners have already invested around 300 million dollars at that time.
The partial compensation was the beginning of the International gamma ray integrator offered with a rocket of protons and executed in 2002. Furthermore, the interest fell as observers like Chandra and XMM-Newton covered much of the same capabilities. But they did not provide overview shots.
