Ariane 5 | February 1, 2019
Launch readiness confirmed for Flight VA247's Ariane 5: Approval is given for the first Arianespace mission of 2019

Arianespace's year-opening Ariane 5 flight has been authorized for liftoff on February 5 following today's launch readiness review, which was conducted at the Spaceport in French Guiana.



This milestone confirmed that the heavy-lift launcher and its dual-satellite payload – comprised of Saudi Geostationary Satellite 1/Hellas Sat 4 (HS-4/SGS-1) and GSAT-31 – are flight-ready, along with the Spaceport's infrastructure and the network of downrange tracking stations.

With approval granted, Ariane 5 is cleared for Monday's rollout from the Spaceport's Final Assembly Building to its ELA-3 launch zone. Liftoff will occur the following day during a 61-minute launch window that opens at 6:01 p.m. local time in French Guiana.

Ariane 5 will deliver a total payload lift performance of 10,018 kg. on the mission to geostationary orbit, which is designated Flight VA247. This total includes the two satellite passengers, plus the workhorse vehicle's dual-payload deployment system and integration hardware.

Ariane 5  |  February 4, 2019
Ariane 5 reaches the launch zone for Arianespace's year-opening mission



The Ariane 5 for Arianespace's Flight VA247 has reached the launch zone in French Guiana, positioning this vehicle for tomorrow's dual-payload mission with Saudi Geostationary Satellite 1/Hellas Sat 4 (HS-4/SGS-1) and GSAT-31.

Riding atop a mobile launch table, Ariane 5 today completed its transfer fr om the Spaceport's Final Assembly Building – wh ere its two passengers were integrated – to the dedicated ELA-3 launch complex. This paves the way for tomorrow's liftoff, which is planned during a 61-min. launch window that opens February 5 at 6:01 p.m. local time in French Guiana.

Today's rollout from the Spaceport's Final Assembly Building marked one of the final milestones in preparations for Flight VA247, which will kick off Arianespace's 2019 launch activity. The company is planning up to 12 missions this year using the heavy-lift Ariane 5, medium-lift Soyuz and lightweight Vega.

A dual-payload deployment

Flight VA247 will be carrying a payload estimated at 10,018 kg. This total factors in the two satellite passengers' combined liftoff mass, as well as hardware for Ariane 5's dual-payload deployment system.

Riding in Ariane 5's upper position, HS-4/SGS-1 is to be released first in the flight sequence, with its separation occurring 27 minutes after liftoff. Built by Lockheed Martin Space, it is a geostationary "condosat" for Saudi Arabia's King Abdulaziz City for Science and Technology (KACST) and Greek-Cypriot satellite operator Hellas Sat, an Arabsat subsidiary.

Completing the mission will be the deployment of Ariane 5's lower passenger, GSAT-31, which will occur 42 minutes after the flight begins. This spacecraft was designed and manufactured by the Indian Space Research Organisation (ISRO) to reduce the digital divide in India.

For its first launch of 2019, Arianespace will orbit two telecommunications satellites using an Ariane 5 from the Guiana Space Center: Saudi Geostationary Satellite 1/Hellas Sat 4, a condosat for KACST (and Hellas Sat; along with GSAT-31 for the Indian Space Research Organisation (ISRO). Through this 103rd Ariane 5 mission – the 70th with an Ariane 5 ECA version – Arianespace confirms its leadership in the geostationary launch services market segment. Composed of two payloads, Saudi Geostationary Satellite 1/Hellas Sat 4, also called HS- 4/SGS-1, is a geostationary condosat for KACST (King Abdulaziz City for Science and Technology – Saudi Arabia) and Hellas Sat (Greece – Cyprus). To be installed as Flight VA247's upper passenger, HS-4/SGS-1 will provide telecommunications capabilities, including television, Internet, telephone and secure communications in the Middle East, South Africa and Europe. The Saudi Geostationary Satellite 1 communications payload will provide advanced Ka-band spot beam communications services for the Kingdom of Saudi Arabia's KACST, including secure communications for the Gulf Cooperative Council region. KACST is an independent scientific organization of the government of Saudi Arabia that is responsible for the promotion of science and technology in the Kingdom. The Hellas Sat 4 communications payload, on the other hand, will offer advanced Ku-band regional beam communications services for Arabsat's subsidiary Hellas Sat, a Greek-Cypriot satellite operator which provides services to leading Direct-to-Home (DTH) operators by delivering contents to more than 3 million households. With a design life of more than 15 years with orbital maneuver up to 23 years, HS-4/SGS-1 will be positioned at 39° East and will join Hellas Sat 3, launched by Arianespace on June 28, 2017 from the Guiana Space Center (on Flight VA23    . Since the launch of Arabsat-1A in 1985, Arianespace has expanded its services to the Middle East, and since then, has developed a trust-based relationship with historical telecommunications operations such as Arabsat. As such, HS-4/SGS-1 will be the 22nd satellites orbited for the Middle East region, accompanying the development of middle-eastern space programs. Headquartered in Bethesda, Maryland, USA, Lockheed Martin Space designed, assembled and integrated the HS-4/SGS-1 satellite in its Denver, Colorado and Sunnyvale, California facilities. HS-4/SGS-1 will be the 46th Lockheed Martin satellite to be launched by Arianespace, whose backlog comprises one additional satellite built by the American manufacturer. Following the launch of GSAT-11 for the Indian Space Research Organisation (ISRO) using the yearending Ariane 5 of 2018, Arianespace will orbit GSAT-31 utilizing the initial Ariane 5 in 2019. To be installed as Flight VA247's lower passenger, GSAT-31 is a telecommunications satellite designed and manufactured by the Indian space agency. To be positioned at a longitude of 48° East, GSAT-31 is configured on ISRO's enhanced I-2K bus structure to provide communications services from geostationary orbit in Ku-band for a lifetime greater than 15 years. By operating GSAT-31, ISRO will – once again – foster the use of space to help bridge the digital divide in the Indian subcontinent as part of its ambitious space program, whose objectives are to develop India while pursuing science research and planetary exploration. Since the launch of India's APPLE experimental satellite on Ariane Flight L03 in 1981, Arianespace has orbited 22 satellites and signed 24 launch contracts with the Indian space agency. It has also won 89% of the geostationary orbit launch contracts opened to non-Indian launch vehicles. The orbiting of GSAT-31 – along with GSAT-30, which is an additional geostationary satellite to be lofted soon by the European launch services provider, Arianespace – marks another vivid demonstration of the strong bond uniting Europe and India in space cooperation.
