SES selects Arianespace for launch of SES-17

SES has selected Arianespace to launch its high-power, high-throughput satellite SES-17 on an Ariane 5 in 2021 from the Guiana Space Center in Kourou, French Guiana. This was announced by SES and Arianespace in Paris today. SES-17 is a powerful satellite delivering high-speed inflight connectivity and high-powered data services over the Americas and the Atlantic Ocean. SES-17 is the 53rd satellite entrusted to Arianespace for launch by SES.

Weighing more than six metric tons at launch, SES-17 will be among the 10 largest telecom satellites launched by Arianespace since the company’s founding. SES-17 is the third all-electric satellite for which SES has chosen an Arianespace launch. The satellite built by Thales Alenia Space is fitted with an electric propulsion system for orbital positioning and station-keeping; its payload comprises 200 Ka-band spotbeams; the orbital position of the spacecraft has not yet been disclosed.

“SES and Arianespace have developed an exceptional partnership over the past 30 years”, said Martin Halliwell, Chief Technology Officer of SES. “With this launch, we build on that relationship and underline our commitment to the European space industry. Together with today’s agreement with Arianespace to launch another four spacecraft of our O3b constellation on Soyuz in 2019, we are satisfied to conclude two important contracts with Arianespace giving us the necessary and reliable access to space that we need to further develop and drive our business.”
