MOSCOW. Oct 3 (Interfax-AVN) - Russia will orbit its Radioastron telescope by the end of 2008, said Nikolai Kardashev, head of the Russian Physics Institute's Astro-Space Center. "It is expected that the astrophysical observatory Radioastron will be orbited in late 2007. A slight delay is possible. I think that in any case this will not happen later than 2008," Kardashev told a news conference on Tuesday. The total cost in creating the telescope is about 3 billion rubles, he said.
