Spectr-R Helps Create Telescope with 350,000km Aperture

Researchers at the Max Planck Institute for Radio Astronomy in Bonn and the Astro Space Center in Moscow have published the interferometric results from a joint observation between the radio telescope aboard the Spektr-R satellite and the Effelsberg 100-m receiver. With a distance between them of 350,000 kms, a resolution of 40 micro arc seconds was acheived.

The target was BL Lacertae, an Active Galactic Nucleus approximately 900 million light years away.

Observatory: Spektr-R & RadioASTRON

Spectr-R is an orbiting 10m radio telescope , the largest when launched 0631hrs 18 July 2011 from Baikonur Cosmodrome. Once in space, the flower-like main dish opened its 27 'petals' successfully within 30 minutes. Spectr-R has a highly elliptical orbit around earth.

Spectr-R is operated as part of RadioAstron, an international space VLBI project led by the Astro Space Center of Lebedev Physical Institute in Moscow, Russia. 


The telescope is capable of ultra-high resolution. The very high angular resolving power is achieved when used in conjunction with a ground-based system of radio-telescopes as part of RadioASTRON, operating at wavelengths of 1.35–6.0, 18.0 and 92.0 cm.

With its Earth-based components, it forms a network providing detailed images of the universe at 1,000 times the resolution attainable using the Hubble telescope.
