anik - 27/3/2007 9:49 AM The answer from Jonathan's Space Report No. 566: Kosmos-2421 A Russian Navy US-PU satellite for ocean electronic surveillance was launched from Baykonur on Jun 25 and codenamed Kosmos-2421. The Tsiklon-2 rocket put it in an approximately 100 x 400 km transfer orbit, and the US-PU onboard engine performed the insertion burn to a 405 x 415 km x 65.0 deg operational orbit.
Thanks, that 100 km perigee explains why not too many Tsyklon-2 upper stages are seen in orbit.

Does anybody know the trajectory profile, burn schedules, etc, for the Soyuz or Progress when going up to the ISS?

Is it possible to watch any launch at baikonur ? Can one go as a tourist there ?

Are there plans for another similar satellite in the next years? Or is the task being taken over by different constellations and satellites?
