KRT-25 Radio Telescope


Russian radio astronomy satellite. Study 1990. In collaboration with the European Space Agency, a 25 m diameter space radio telescope was studied for launch by Energia in 2001.

The satellite would have permitted study of the mechanisms of the generation of relativistic energy, mapped in detail radio sources and quasars, studied the black matter problem, and detected new types of celestial objects. The 27.8 metric ton satellite would be equipped with a 5 kWt power supply, of which 1.5 kW would be available for scientific instruments. Its radio interferometer would operate in the frequency range of 5 to 200 GHz. During its five year life in a 63.45 deg orbit, it would maneuver to successively higher orbits. Two years would be spent in a 5,000 km x 20,000 km orbit, followed by two years in a 5,000 x 40,000 km orbit, and the final year in a 5,000 x 150,000 km orbit.

Gross mass: 27,800 kg (61,200 lb).

  • Energia The Energia-Buran Reusable Space System (MKS) began development in 1976 as a Soviet booster that would exceed the capabilities of the US shuttle system. Following extended development, Energia made two successful flights in 1987-1988. But the Soviet Union was crumbling, and the ambitious plans to build an orbiting defense shield, to renew the ozone layer, dispose of nuclear waste, illuminate polar cities, colonize the moon and Mars, were not to be. Funding dried up and the Energia-Buran program completely disappeared from the government's budget after 1993. More...
