Arianespace to Launch 2 Telecom Satellites Into Geostationary Orbit

  • The sixth Arianespace launch of 2021 with the first Ariane 5 of the year, scheduled for July 30, will orbit two geostationary telecommunications satellites, Star One D2 and EUTELSAT QUANTUM.
  • This VA254 mission for two long-standing customers clearly reflects the excellence of Arianespace's services and relations of mutual trust with its customers.

Arianespace’s next Ariane 5 launch from the Guiana Space Center (CSG) in Kourou, French Guiana, is scheduled for Friday, July 30, during a launch window from 21:00 to 22:30 UTC. Initially planned for July 27, the mission was rescheduled after a revision to the preparation schedule.

The two satellites are being launched for two long-standing Arianespace customers: Embratel, the largest satellite operator in Brazil and Latin America and Eutelsat, one of the world’s leading satellite operators. Arianespace has already orbited 11 satellites for Embratel and 35 satellites for Eutelsat.

Star One D2 is a high-capacity, multi-mission satellite with Ku-, Ka-, C- and X-band transponders that will enable it to expand broadband coverage to new regions in Central and South America, provide internet access to underserved populations and add an updated X-band payload for government use over the Atlantic region. Built on Maxar’s proven 1300-class platform at the company’s Palo Alto, California, manufacturing facility, Star One D2 will improve access to high-quality services, serving the parabolic fleet in Brazil, Pay TV, cell phone backhaul, data, video and Internet for corporate customers and government agencies.

EUTELSAT QUANTUM was developed under a public-private partnership between the European Space Agency (ESA), operator Eutelsat and Airbus Defence and Space. Using a software-based design, EUTELSAT QUANTUM will be the world’s first universal satellite to repeatedly adjust to business requirements. It features an electronically steerable receiving antenna and operates in Ku-band with eight independent reconfigurable beams. This configuration allows the operator to reconfigure in-orbit the radio-frequency beams over the coverage zones, providing unprecedented flexibility in data, government and mobility services.

This mission will use the Ariane 5 heavy-lift launcher developed and manufactured by ArianeGroup within the scope of a joint European government-industry program. Arianespace is responsible for marketing and operating Ariane 5 launches from the Guiana Space Center in Kourou, French Guiana. The French space agency CNES is the launcher design authority and ESA is the project owner of the program. ArianeGroup is in charge of all design and production, from initial design studies, upgrades and manufacturing, to the supply of data and software for each mission. Its specific responsibilities include the production of equipment, structures and propulsion systems, integration of the different stages, and integration of the complete launcher in French Guiana.
