Intelsat-19 Launch


SC Intelsat-19 is the communication satellite manufactured by Space Systems/Loral (SS/L) company based on Bus 1300 and its mass is 5 600 kg.

Intelsat-19 mission was prepared at the Home Port from April 9 to May 15, 2012.
LV Zenit-2S No. SL33 and Block DM-SL No. 32L were used to launch the Intelsat-19 SC.
