JCSat-9 Launch

The "JCSat-9" mission preparation began in March 2006 upon successful completion of operations for the Echostar-10 mission.
To launch the "JCSat-9" SC it was planned to use the Zenit-2S LV SL21 and Block DM-SL 22L. It was expected to carry out the prelaunch processing of the Zenit-2S LV SL20 and Block DM-SL 21L as donors.
