3.2 Ascent Trajectory Stage 1 flight The Zenit Stage 1 provides the thrust for the first 2.4 min of flight. The vehicle begins a roll to the appropriate launch azimuth at approximately 10 sec. The pitch profile is designed to minimize the loads during the periods of highest dynamic pressure. The engine is throttled during the final seconds to limit the maximum axial acceleration. Stage 2 flight The Zenit Stage 2 main and vernier engines provide the thrust for the next 6.2 min flight. Stage 2 vernier ignites prior to Stage 1 separation. The vernier engine operates alone for the initial 5 sec and final 75 sec of Stage 2 operation. The payload fairing is jettisoned 1 min into Stage 2 flight. Immediately after Stage 2 separation, the middle adapter surrounding the Block DM-SL is jettisoned. Block DM-SL flight The Block DM-SL provides the final 10.7 min of powered flight. Depending on mission requirements, the Block DM-SL performs one to five burns. For multiple burn missions, the initial burn establishes a stable parking or phasing orbit. 3-4 D688-10009-1 REV B
