LAUNCH!!!
No one seems to have commented on the use of the Fregat-SB variant for this launch. The "SB" means that an extra propellant tank is being used, which AFAIK is to be jettisoned after its propellant is depleted, much like the Briz-M APT. So ... this implies that there will be a jettison event prior to separation of the spacecraft.
Another question to ask is, what is the name of this rocket?
11K77 Zenit-3SLBF/Fregat-SB (1-2007/1-1001)
