Spektr-R No. 2520, RadioAstron space radio observatory with 10m antenna. Launch by Zenit/Fregat into 600 x 350000 km.
or a = 189000 km i = 51.6 p = 9.5 d e = 0.853 so 21405 x 343840
P = 29000 km or 600 x 330000 or (2008) 500 x 350000
Astro Space Center (ASC) of Lebedev Physical Institute of Russian Academy of Sciences (RAS)
Uses Lavochkin Navigator bus.
3660 kg mass with 500 kg hydrazine. Launch by Zenit-2SB80 with Fregat-SB, in a Zenit-3SLBFSBM variant (the Zenit-3SL is the standard Sea Launch / Blok D version, Zenit-3SLB is the Baykonur variant of that, 3SLBF is the Fregat upper stage version, but this uses not just the extra-tank Fregat-SB but a modified version Fregat-SBM -- hence, 3SLBFSBM). ftp://www.asc.rssi.ru/symp2008/BabyshkinRA.pdf For June 21 2010 launch we have a = 171571.6, w = 303 , i = 51.4, node = 304, peri = 0448:43 on Jun 21.
