Hello,
Launch of next 7 Iridium satellites onboard of the Proton launcher
is scheduled on Jun 18. These are SVN009, 010, 011,012, 013, 014 and
016. SVN016 will be launched instead of SVN015 due to 015 was

012 and 013 ones on May 18, 014 - on May 25, 016 - on Jun 01.
The Block DM-5 upper stage will be used at this launch. This upper
stage is the same type one that was used on Jun 06 Proton launch.
Following launch profile will be used:
T0 - lift-off
T0+2m26.6s - 1st stage separation
T0+5m37.9s - 2nd stage separation
T0+5m46.5s - payload shroud separation
T0+9m51.3s - 3rd stage/(DM-5 + payload dispencer + 7 spacecrafts)
separation, initial circular orbit (H=170.4 km, i=73 deg)
T0+37m04s - DM-5 main engine 1st burn (transfer orbit, 170x516, 73deg)
T0+80m32s - DM-5 main engine 2nd burn (parking orbit, circ. 516km, 86.4deg)
T0+88m23s - DM-5/(7 spacecrafts) separation
T0+1h57m26s - DM-5 main engine 3rd burn (deorbit burn)
T0+2h25m35s - falling of the DM-5 into the Pacific
