The SES and Orbital Sciences Corporation teams here are happy to report, the SES-1 spacecraft successfully completed its standalone testing – one of the first major hurdles to getting to launch. After standalone testing finished, the Propellant team from Orbital Sciences, with support from ILS and KhSC, filled the SES-1 spacecraft with hydrazine propellant. This potentially hazardous operation was safely completed yesterday, paving the way for joint operations to begin today, 11 April. This is the next phase of the campaign, where we start mating the various components together to make the integrated launch vehicle.
