Intelsat 21 launched by the Sea Launch system

At 10:55 Moscow Time (06:55 UTC) 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 21 spacecraft (SC).

The launch objective is to deliver a spacecraft with a mass of about 6 metric tons into a geotransfer orbit.

Insertion of the spacecraft from its low parking orbit into its target orbit was performed by the upper stage Block DM-SL made by RSC Energia.

The mission plan, which called for a single burn of the upper stage main engine in automatic mode, has been completely fulfilled.

The firing of the main engine took place at ~8.5 min after the lift-off`(10 sec after separation of the upper stage carrying the SC from the second stage of the launch vehicle). The main engine burn lasted about 11.5 min.

The upper stage delivered the SC to its target orbit to high precision. The spacecraft separated from the upper stage at 11:25 Moscow Time.

The flight of the upper stage Block DM-SL carrying the SC was analyzed by RSC Energia specialists working at the Mission Control Center for RSC Energia upper stages and unmanned spacecraft who were continuously in touch with the Control Center located onboard the vessel Sea Launch Commander belonging to the Sea Launch system.

The work was supervised by RSC Energia President and General Designer V.A. Lopota.

Pre-launch processing and launch of the LV carrying the upper stage and the SC were performed onboard the Sea Launch Commander ship and the Odyssey launch platform by the launch team which were directly supervised by 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 of RSC Energia V.A. Lopota and managers and launch guests staying onboard Sea Launch Commander. The General Designer welcomed them and, on behalf of the partners in the program, expressed his sincere gratitude to the customer of this launch, the Intelsat company, for their support of the Sea Launch program.

 

For reference:

  1. This launch was the third launch under the Sea Launch program after reorganization of the Sea Launch company, and the 33rd launch under the entire program of launches from the Odyssey launch platform.
  2. Upper stages of Block DM type developed and manufactured by RSC Energia were designed for transporting 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. RSC Energia is the prime contractor for the Sea Launch rocket segment and is responsible for its outfitting and integration in the overall system, supporting, together with its subcontractors, the manufacturing and operation of the upper stage Block DM-SL as the third stage of Zenit-3SL ILV.
