Separation of DSN 1/Superbird 8 was called out by the DDO while the commentator was talking about the ground team! The view was of the ground track, so that is why we missed seeing the separation.

Mission success: Flight VA242 orbits DSN-1/Superbird-8 for SKY Perfect JSAT and HYLAS 4 for Avanti Communications


April 5, 2018 – Arianespace has successfully launched two telecommunications satellites: DSN-1/Superbird-8 for the Japanese operator SKY Perfect JSAT; and HYLAS 4 for the British operator Avanti Communications.

 Arianespace’s third launch of the year took place on Thursday, April 5, 2018 at 6:34 p.m. (local time) from the Guiana Space Center (CSG), Europe’s Spaceport in French Guiana.
 
With this 98th launch of Ariane 5, the heavy-lift launcher has now transported more than 200 satellites since its entry in service.
 

Arianespace: long-standing partner to SKY Perfect JSAT, and the operator of reference in Japan

DSN-1/Superbird-8 is the 19th satellite launched by Arianespace for SKY Perfect JSAT. SKY Perfect JSAT is the leading satellite operator in Asia, and plays a major role in the satellite broadcasting and telecommunications markets.

 Arianespace has two more SKY Perfect JSAT satellites in its order book: Horizons 3e and JCSAT-17.

 Superbird-8 will provide telecom services, primarily for the Japanese market, and will replace Superbird-B2, launched by Arianespace in 2000.

 DSN-1 is an X-Band Defense Communications Satellite, in association with the Program to Upgrade and Operate X-Band Satellite Communications Function, for which the DSN Corporation, a subsidiary of SKY Perfect JSAT, has concluded a program contract with Japan’s Ministry of Defense.

 With this latest successful launch, Arianespace confirms its status as a benchmark launch services provider for the country’s two leading operators, SKY Perfect JSAT and B-SAT.

 Since launching JCSAT-1 in 1989, Arianespace holds nearly 75% of the Japanese geostationary satellite launch market open to competition.
   
Arianespace at the service of Avanti Communications

Arianespace has launched the entire operational fleet of British operator Avanti Communications. HYLAS 4 is the third satellite launched for this company by Arianespace, following HYLAS 1 (in November 2010) and HYLAS 2 (August 2012). The HYLAS 3 auxiliary payload, integrated in the EDRS-C satellite, will be launched as well by Ariane 5.

 At the forefront of Ka-band satellite communications in Europe, Africa and the Middle East, Avanti Communications’ HYLAS satellite fleet provides broadband Internet access via top service providers to homess, schools, Mobile Network Operators (MNOs) and governments.

 Thanks to its Ka-band capacity, HYLAS 4 will provide secure and reliable satellite communications services to Internet Service Providers (ISP), Mobile Network Operators (MNO’s), governments and satellite operators throughout Europe. This High Throughput satellite will also cover regions in central and western Africa, while its steerable spotbeams will enable it to cover Europe, the Caribbean, the Middle East and South America. 
 

Ariane 5 has launched more than 200 satellites since 1996

With today’s Flight VA242 mission, the 98th completed by Ariane 5 since it entered service in 1996, Arianespace has now launched its 200th and 201st satellites with its heavy-lift launcher. This is a record for the Ariane launcher family, since the previous generation of Ariane 4 vehicles had orbited a total of 187 satellites during its entire service life. The 201 satellites were launched for 70 different customers, amounting to a cumulative total mass more than 775 metric tons.

 Shortly after the announcement of the orbital injection of the two satellites, Stéphane Israël, Chief Executive Officer of Arianespace, said:

“Arianespace is very proud to serve our Japanese and British customers with this third launch of 2018. We are very honored by SKY Perfect JSAT’s ongoing trust in us, since we have launched 19 of their satellites since 1989; and by the trust of the Japanese Ministry of Defense. Congratulations go to Avanti Communications, which has entrusted us with the launch of all three of its satellites now in orbit. I would like to congratulate NEC Corporation and Mitsubishi Electric Corporation, builders of DSN-1/Superbird-8, and Orbital ATK, which built HYLAS 4.

“I would also like to thank all of our partners in this new Ariane 5 success which confirms the launcher’s outstanding reliability: ArianeGroup, together with the entire industrial sector; ESA, which provides key support for the Ariane program; CNES/CSG, our ground segment companies and all staff at the launch center, who are mobilized with us for a sustained launch rate. And finally, “bravo” to everyone at Arianespace who successfully completed this third launch of the year.”

200+ satellites launched: Ariane 5 surpasses key milestone on its latest dual-payload success

Telecommunications satellites for two major Arianespace customers – Japan’s SKY Perfect JSAT Corporation and Avanti Communications of the UK – were orbited today on a record-breaking flight for the launch services provider.

Ariane 5 lofted the DSN-1/Superbird-8 and HYLAS 4 payloads from Europe’s Spaceport in French Guiana during a flight lasting just under 34 minutes, and in doing so, exceeded the 200-mark in the number of satellites launched during its operational career (DSN-1/Superbird-8 is #200; HYLAS 4 is #201).

The heavy-lift workhorse delivered an estimated total lift performance of 10,260 kg. on today’s flight to geostationary transfer orbit injection, which included the two passengers and hardware for its dual-payload deployment system. Designated Flight VA242 in Arianespace’s launcher family numbering system, this mission was the 242nd launch of an Ariane-series vehicle to date, as well as the 83rd Ariane 5 success since 2002.

Another launch at the service of Japan

As the 19th SKY Perfect JSAT satellite entrusted to Arianespace for launch, DSN-1/Superbird-8 – a dual-use relay platform – rode in the upper passenger position on Ariane 5 and was deployed first on today’s flight.

Its Superbird-8 payload uses high-performance Ku- and Ka-band transponders for communications services primarily in the Japanese market. DSN-1 is an X-Band Defense Communications Satellite, in association with the Program to Upgrade and Operate X-Band Satellite Communications Function, for which the DSN Corporation, a subsidiary of SKY Perfect JSAT, has concluded a program contract with Japan’s Ministry of Defense.

“We are proud to help provide civilian and defense satellite communication services for the Japanese market and Japan’s Ministry of Defense,” said Arianespace CEO Stéphane Israël, who provided his post-flight comments from the Spaceport’s mission control center.

Koki Koyama, Board Director and Senior Managing Executive Officer of SKY Perfect JSAT, thanked Arianespace for today’s mission success and noted that his company’s first satellite – JSAT-1 – was launched on an Ariane vehicle in March 1989. “JSAT-1 served many customers and became part of the business foundation of SKY Perfect JSAT,” he said, adding that SKY Perfect JSAT was now looking forward to a long life with DSN-1/Superbird-8 at the service of both civilian and defense ministry operators.

DSN-1/Superbird-8 was produced by MELCO (Mitsubishi Electric Corporation) using a DS2000 platform, with manufacturing management provided by NEC Corporation. It is the third MELCO-built satellite to be launched by Arianespace and will operate from a final orbital position at 162 deg. East Longitude.

Delivering satellite communications across Europe

Completing today’s mission was the deployment of HYLAS 4, which was released from Ariane 5’s lower passenger position. Once it its final orbital slot of 33.5 deg. West Longitude, this platform will deliver high-speed, reliable and secure satellite communications in Ka-band to Internet service providers (ISPs), mobile network operators (MNOs), governments and satellite operators across Europe.

Calling Flight VA242 a “spectacular launch,” David Bestwick, Chief Technical Officer for Avanti Communications, acknowledged Arianespace’s 100 percent mission success rate in support of his company’s operations. “HYLAS 4 is extremely important to Avanti,” Bestwick explained in post launch comments from the Spaceport. “It more than doubles the communications capacity that we have in orbit, and completes our coverage of Africa and the Middle East.”

Arianespace’s Stéphane Israël said that with the launch of Avanti Communications’ high-throughput satellite, Arianespace is proud to help provide services in regions such as West and Central Africa. Produced by Orbital ATK, HYLAS 4’s steerable beams also enable coverage for Europe, South America, the Caribbean and Middle East.

The Arianespace CEO also gave special thanks to Ariane 5 production prime contractor ArianeGroup, the European Space Agency, the French CNES space agency, the ground contractors in French Guiana and his own teams at Arianespace.

The 2018 launch cadence continues

Flight VA242 was Arianespace’s third mission so far this year. Next up in the company’s launch manifest is another with Ariane 5: Flight VA243, which is scheduled to orbit the GSAT-11 and Azerspace-2/Intelsat 38 satellites on May 25.

Orbital ATK-Built Hylas 4 Commercial Communications Satellite Successfully Launched

HYLAS 4 is Company’s Third GEOStar-3 Satellite to Launch This Year

Initial On-Orbit Testing Shows Satellite Performing Nominally

Dulles, Virginia 05 April 2018 – Orbital ATK (NYSE: OA), a global leader in aerospace and defense technologies, today announced the HYLAS 4 commercial communications Ka-band satellite, built by the company for Avanti Communications Group plc (Avanti), was successfully launched aboard an Arianespace rocket. HYLAS 4 is the third GEOStar-3™ satellite to be completed by Orbital ATK and will provide high speed and affordable broadband communications to Europe and Africa.

Liftoff occurred at 5:34 p.m. EDT from Kourou, French Guiana. The satellite separated successfully from the launch vehicle approximately 35 minutes into the mission after reaching its targeted orbit. Orbital ATK completed the satellite’s initial post-launch health check and configuration in preparation for orbit-raising procedures and in-orbit tests. The spacecraft handover to Avanti is anticipated in April.

“The data from initial testing shows the satellite is in good health and performing as expected,” said Amer Khouri, Vice President of the Commercial Satellite business at Orbital ATK.  “As the third GEOStar-3 satellite to launch within three months, HYLAS 4 demonstrates Orbital ATK’s ability to develop and execute an enhanced product that offers increased capability to meet our customers’ emerging needs.”

HYLAS 4 was built in Orbital ATK’s satellite manufacturing facility in Dulles, Virginia. It is a hybrid electric propulsion and all Ka-band high-throughput satellite that sets a new standard for affordability and payload flexibility in its class. The satellite will extend Avanti’s Ka-band coverage across Europe, the Middle East and Sub-Saharan Africa. Furthermore, additional capacity can be provided through four steerable beams, which can address existing regions or new regions such as Latin America.

The GEOStar-3 platform is the newest, highest power and most advanced platform in the flight-proven GEOStar product line. The spacecraft bus features an increase in both battery capacity and solar array power, enabling the GEOStar-3 to provide up to 8 kilowatts of power to the payload. The hybrid electric propulsion system provides the benefits of higher power and greater payload capability while maintaining cost-effective launches and a faster path to orbit than all electric systems.
