Russian x-ray astronomy satellite. One launch, 1989.12.01. Granat was a Lavochkin design with the mission of making gamma ray observations in energy ranges of 3 to 200 keV.
It was equipped with the ART-P and Sigma telescopes for observation of galactic cores, x-ray pulsars, and black holes. The satellite conducted studies of X-ray and soft gamma ray radiation sources in space by the USSR jointly with France, Denmark and Bulgaria.
Gross mass: 3,200 kg (7,000 lb).

Proton The Proton launch vehicle has been the medium-lift workhorse of the Soviet and Russian space programs for over forty years. Although constantly criticized within Russia for its use of toxic and ecologically-damaging storable liquid propellants, it has out-lasted all challengers, and no replacement is in sight. More...

Proton The Proton launch vehicle has been the medium-lift workhorse of the Soviet and Russian space programs for over forty years. Although constantly criticized within Russia for its use of toxic and ecologically-damaging storable liquid propellants, it has out-lasted all challengers, and no replacement is in sight. Development of the Proton began in 1962 as a two-stage vehicle that could be used to launch large military payloads or act as a ballistic missile with a 100 megaton nuclear warhead. The ICBM was cancelled in 1965, but development of a three-stage version for the crash program to send a Soviet man around the moon began in 1964. The hurried development caused severe reliability problems in early production. But these were eventually solved, and from the 1970's the Proton was used to launch all Russian space stations, medium- and geosynchronous orbit satellites, and lunar and planetary probes. More...
Proton-K/D-1 Russian orbital launch vehicle. This derivative of the original four stage Block D / 11S824 version of the Proton was used from 1978 to launch Lavochkin OKB planetary probes (Mars, Venera) and high earth orbit astronomical observatories (Astron, Granat). Guidance to the Block D-1 stage must be supplied by spacecraft. Equipped with N2O4/UDMH verniers for precise placement of payloads in high orbits or planetary trajectories. More...

Associated Launch Sites
Baikonur Russia's largest cosmodrome, the only one used for manned launches and with facilities for the larger Proton, N1, and Energia launch vehicles. The spaceport ended up on foreign soil after the break-up of Soviet Union. The official designations NIIP-5 and GIK-5 are used in official Soviet histories. It was also universally referred to as Tyuratam by both Soviet military staff and engineers, and the US intelligence agencies. Since the dissolution of the Soviet Union the Russian Federation has insisted on continued use of the old Soviet 'public' name of Baikonur. In its Kazakh (Kazak) version this is rendered Baykonur.
