As of 2020, SES was broadcasting over 50 Ultra HD channels worldwide. SES-8 was the first geostationary satellite to be launched (in 2013) by SpaceX. The SES-10 satellite, was launched in March 2017 (delayed from October 2016 due to a pad explosion and subsequent loss of a Falcon 9 booster in September 2016) on the first SpaceX launch with a 'flight-proven' (reused) Falcon first stage, recovered from a previous launch. The SES-12, SES-14 and SES-15 satellites (launched in June 2018, January 2018 and May 2017, respectively) are constructed with an electric plasma propulsion system for orbit raising and in-orbit manoeuvres to save weight and enable a larger communications payload to be included. SES reckons that SES-12 would weigh some 4700 kg more with a conventional chemical propulsion system. SES operates the world’s first multi-orbit communications satellite network, combining geostationary orbit satellites’ wide coverage and reliability, and a medium Earth orbit satellite constellation's low latency and high data throughput. In conjunction with Kythera Space Solutions, SES developed Adaptive Resource Control (ARC) software to dynamically control and optimise power, throughput, and beam and frequency allocation across the multi-orbit network of the O3b and forthcoming O3b mPOWER medium Earth orbit satellite system, and SES-17 and future geostationary high-throughput satellites. SES is the first commercial customer for Space Infrastructure Servicing (SIS) future satellite life extension mission, following an agreement in June 2017 with MacDonald, Dettwiler and Associates (MDA). The SIS craft was being built by Space Systems/Loral (SSL), a manufacturing subsidiary of MDA, for the United States Defense Advanced Research Projects Agency (DARPA)'s Robotic Servicing of Geosynchronous Satellites (RSGS) programme, and will refuel an SES satellite running low on propellant while still in orbit to lengthen its service life. SSL (as Maxar) abandoned the DARPA contract in 2019. Corporate structure Corporate management SES is managed by the Senior Leadership Team which comprises: Steve Collar – CEO John-Paul Hemingway - Chief Strategy and Product Officer John Baughn - Chief Services Officer Christophe De Hauwer – Chief Development Officer Sandeep Jalan - Chief Financial Officer Ruy Pinto - Chief Technology Officer Pan Macdonald - Chief People Officer Thai Rubin - Chief Legal Officer In 2002, the then CEO, Romain Bausch was awarded 'Satellite Executive of the Year'. Current CEO, Steve Collar was awarded 'Satellite Executive of the Year' for 2019. History Early years SES was formed on the initiative and support of the Luxembourg Government in
