Spektr R



Spektr R, a Russian radio astronomy satellite, was launched from Baikonur on 18 July 2011 at 02:31 UT by a Zenit 3F rocket. Spektr R is one element of an international network of observatories in a project called RadioAstron. Funded by the Russian Astro Space Center, Spektr R features a 10-m diameter antenna reflector designed to help astronomers see deeper into supermassive black holes, obtain views of collapsed stars, and better measure the influence of dark energy on the cosmos. When linked together, RadioAstron's telescopes have a resolution of 7 microarcseconds.
