Intelsat 21 is scheduled to launch on a Zenit-3SL from the Odyssey platform out a sea on the equator at 154 degrees West longitude. Intelsat will provide 15 years or more service, carrying 24 C-Band transponders and 36 Ku-band transponders. Launch will occur on August 18th 2012 at 06:56 UTC. The Zenit will lift off and the first stage will burn for two and a half minutes, The second stage will then burn for 6 minutes. Once the second stage separates from the Block DM-SL upper stage, the upper stage will conduct a nearly 12 minute burn before coasting for 10 minutes before payload separation. Intelsat 21 will separate at 30 minutes into the mission.
