Intelsat-19 launched from the Odyssey platform of the Sea Launch system

At 09:23 AM Moscow Time (05:23 AM GMT), the seagoing Launch Platform (LP) Odyssey belonging to the space rocket launching system Sea Launch and located in the equatorial area of the Pacific Ocean at 154 W launched an Integrated Launch Vehicle (ILV) Zenit-3SL carrying as its payload INTELSAT-19 spacecraft (SC).

The launch objective is to deliver the 5.6-ton spacecraft into a geotransfer target orbit.

The spacecraft insertion into this orbit was performed by the space upper stage Block DM-SL, designed and built by S.P. Korolev RSC Energia, from an intermediate low Earth orbit, where the upper stage with the spacecraft had been delivered by the two-stage launch vehicle Zenit-2S.

The mission plan, which called for two burns of the upper stage main engine in automatic mode, has been fully completed.

The first burn of the main engine occurred ~8.5 minutes into the flight (10 seconds after the separation of the upper stage DM-SL carrying the SC from the LV second stage). The first burn lasted about 5.1 minutes. The second burn occurred ~43.8 minutes after the launch, the duration of the burn was about 6.5 minutes.

The upper stage delivered the SC to its target orbit with high accuracy.

The flight of the upper stage Block DM-SL carrying the SC was analyzed by the RSC Energia experts working within the Lead Operations Control Team at the Mission Control Center for RSC Energia upper stages and unmanned spacecraft, who were in constant contact with the Control Center on-board the Sea Launch Commander ship belonging to the Sea Launch system.

At the Mission Control Center, the launch vehicle and upper stage flight control activities were monitored by the RSC Energia President and General Designer V.A. Lopota.

The work onboard the Sea Launch Commander command ship and Odyssey launch platform to prepare and launch the launch vehicle with the upper stage and spacecraft onboard was performed by a launch team under direct supervision of the RSC Energia deputy general designer V.G. Aliev.

After the SC separated from the upper stage, a video communications session was held between the President and General Designer of RSC Energia V.A. Lopota and the command ship Sea Launch Commander. V.A. Lopota greeted participants and guests of the launch, wished all the participants luck and further successes. On behalf of all the participants and partners in the program he expressed his sincere gratitude to the customer of this launch, the Intelsat Company, for their support of the program and joint efforts to further develop the Sea launch.


For reference:

  1. This was the second launch under the Sea Launch program after reorganization of the Sea Launch company, and the 32nd launch under the entire program.
  2. Upper stages of the Block DM type developed and manufactured by S.P.Korolev RSC Energia were designed for transferring spacecraft from low-Earth orbits to high-energy orbits, including GEO, as well as for spacecraft injection into trajectories that would take them to the Moon and planets of our solar system.
  3. Launches from the sea-going launch site are conducted under the launch services program that was put together by the company.
  4. RSC Energia is the prime contractor for the Sea Launch rocket segment and is responsible for its outfitting and integration in the overall system, providing, together with its subcontractors, the manufacturing and operation of the upper stage Block DM-SL as the third stage of Zenit-3SL LV. .
