Description:

• The two satellites, Intelsat 19 and Intelsat 20, will be among the most powerful FSS satellites ever built with unprecedented capacity to provide services for broadband, video, and voice applications.
• Intelsat 19 and Intelsat 20 will replace existing satellites that currently provide services to five continents and will offer services for broadcast television and telecommunications. The satellites also will have the capacity to support mobile communications and higher data rate network services.
• Intelsat 19 is the 36th satellite that Space Systems/Loral will provide to Intelsat and was scheduled for launch in 2011, delayed to 2012. It will replace the Intelsat 8 satellite at 166 degrees East longitude. The satellite has 34 Ku-band transponders that can be switched between four different footprints that cover Australia and the Pacific Ocean region, and 24 C-band transponders that will be connected to a high-power footprint covering Australia, New Zealand, Southeast Asia, Japan, and the western United States. The satellite's C-band capacity will provide enhanced distribution of content throughout Asia-Pacific with reach to the Western United States.
• Replacement for Intelsat 8. Damage to a solar panel; reduced power.

Mission details:

• On Jun 1, 2012 Sea Launch flew a Zenit-3SL from the Odyssey launch platform on the equator, at 154W 0 N. The rocket's second stage flew to a -2174 x 188 km trajectory, followed by the first burn of the DM-SL third stage which reached a 180 x 1065 km x 0.0 deg parking orbit at 0536 UTC. After a second burn the payload was delivered to an 882 x 35804 km x 0.4 deg geostationary transfer orbit. On Jun 15 the spacecraft was in a 35665 x 35866 km x 0.2 deg orbit over 170.8E.
• Payload of the Zenit is Intelsat IS-19, a Loral 1300 type satellite with a C and Ku-band communications payload for Intelsat. One of the satellite's solar arrays was damaged during ascent, shortly after fairing separation, and investigation is still underway.
• After successful launch in June 2012, the satellite failed to deploy one of the solar panels.
