garnet (rus. Гранат) was a Soviet-Russian X-ray satellite, which developed as joint work between Russia and France. The 5 tons heavy satellite became at the 1. December 1989 with proton - a rocket of the space airport Baikonur into eccentric 2,000 a times; 200.000nbsp; km high orbit with a flight path angle of 51° shot. The scan time amounted to four days.
The satellite worked nearly ten years long, between 1989 and 1999, since spinstabilizes 1994. Garnet had four main instruments. These were the X-ray telescope originating from France named “sigma”, which worked within a range between 30 and 1000 keV, the Russian telescope “kind p “, the control instrument named” Watch “and the Gammastrahlendetektor” Phebus “.
Within four years “garnet” examined many galaxies and receiptable X-ray, which lay outside of our galaxy. Afterwards it was used for further investigations of other objects. In addition garnet took singular photographs of our galaxy center, to the Milky Way, as well as from promising candidates for black holes.
