Ariane 5   August 21, 2017
Flight VA239: Launcher and payload preparations advance for Arianespace’s next Ariane 5 liftoff

The Ariane 5 for Arianespace’s ninth flight in 2017 is being readied for a September 5 liftoff from the Spaceport, while its two satellite passengers – Intelsat’s Intelsat 37e and BSAT-4a for SSL on behalf of Japan’s Broadcasting Satellite System Corporation (B-SAT) – continue their final checkout at the French Guiana facility.

Following its build-up in the Launcher Integration Building, the Ariane 5 has been moved to the Final Assembly Building for the upcoming installation of Intelsat 37e and BSAT-4a – which are now undergoing their own checkout processes in separate halls of the Spaceport’s S5 payload preparation facility.

The upcoming mission to geostationary transfer orbit is designated Flight VA239 in Arianespace’s numbering system, and will mark the 239th launch of an Ariane vehicle since the European launcher series entered service in 1979. The heavy-lift Ariane 5 is operated as part of Arianespace’s launcher family at the Spaceport, which also includes the medium-lift Soyuz and lightweight Vega.

An “Epic” launch at the service of Intelsat

Built by Boeing using a 702MP spacecraft platform, Intelsat 37e is the next satellite in Intelsat’s high-throughput EpicNG series for launch.

It also will be the fourth EpicNG spacecraft orbited by Arianespace to date (following Ariane 5 missions with Intelsat 29e and Intelsat 33e in January and August 2016, respectively, plus last February’s heavy-lift flight that lofted SKY Brasil-1/Intelsat 32e).

Operating in the C, Ku and Ka frequency bands, the spacecraft will provide capacity for wireless backhaul, enterprise VSAT and mobility networks. Intelsat 37e, which is to carry out its mission from a 342-deg. East orbital slot, will weigh approximately 6,440 kg. at liftoff.

Continuing a long and fruitful partnership

Arianespace is launching Flight VA239’s co-passenger, BSAT-4a, as part of a turnkey contract between B-SAT and U.S.-based satellite manufacturer SSL. To be operated from an orbital position of 110 deg. East, this spacecraft will be used for Direct-To-Home (DTH) television relay in Japan and to expand the availability of advanced television services – such as 4K/8K ultra-high definition TV.

BSAT-4a is based on the SSL 1300 satellite platform and is fitted with 24 Ku-band transponders. It will weigh approximately 3,520 kg. at liftoff, with a design life that exceeds 15 years.

Arianespace has a 30-year-plus track record serving operators in the Japanese market – including B-SAT, for which it is the launch services provider of choice.

Flight VA239 will continue Arianespace’s busy schedule in 2017, in which eight launches were performed during the year’s first seven months, utilizing the company’s full launcher family (two with Vega; two with Soyuz; and four using Ariane 5).

This mission will barely be in second place behind the ViaSat 2 & Eutelsat 172B mission in regards to total payload mass to GTO.

VA-239: 10,838 kilograms

Ariane 5 is completed for its dual-payload mission on September 5

The Ariane 5 for Arianespace’s ninth mission of 2017 is now fully assembled following integration of its two satellite passengers at the Spaceport in French Guiana.

During activity in Ariane 5’s Final Assembly Building, the upper payload component – containing Intelsat 37e, mounted on its SYLDA dispenser system and protected by an ogive-shaped fairing – was lowered into position over BSAT-4a, which previously was installed atop the launcher’s central core.

This step clears the way for final checkout, which will enable the launch readiness review to be conducted on September 1, followed by Ariane 5’s rollout to the Spaceport’s ELA-3 launch zone the following Monday, and an evening liftoff on Tuesday, September 5.

The upcoming mission is designated Flight VA239 in Arianespace’s numbering system, and it will deliver the two telecommunications payloads into geostationary transfer orbit.

Telecommunications satellites from long-time customers

To be deployed first during the 47-minute flight sequence is Intelsat 37e – the next satellite in Intelsat’s high-throughput EpicNG series for launch, which was built by Boeing using a 702MP spacecraft platform. This spacecraft will operate in C, Ku and Ka frequency bands, providing capacity for wireless backhaul, enterprise VSAT and mobility networks from a 342-deg. East orbital slot. Intelsat 37e has an estimated liftoff mass of 6,438 kg.

Ariane 5’s second passenger – BSAT-4a, which is being launched as part of a turnkey contract between Japan’s Broadcasting Satellite System Corporation (B-SAT) and U.S.-based satellite manufacturer SSL – will be operated from an orbital position of 110 deg. East. It will be used for Direct-To-Home (DTH) television relay in Japan, as well as to expand the availability of advanced television services (such as 4K/8K ultra-high definition TV). BSAT-4a will weight approximately 3,520 kg. at liftoff.

Flight VA239 will continue Arianespace’s busy schedule in 2017, in which eight launches were performed during the year’s first seven months, utilizing the company’s full launcher family (two with Vega; two with Soyuz; and four using Ariane 5).

September 1, 2017 

Ariane 5 is cleared for launch on Arianespace’s upcoming heavy-lift mission from French Guiana

Arianespace’s fifth Ariane 5 mission of 2017 has been given the “green light” for liftoff on September 5 following today’s successful launch readiness review, which was conducted at the Spaceport in French Guiana.

This milestone – held prior to each Arianespace flight – confirmed that the heavy-lift vehicle and its dual-satellite payload of Intelsat 37e and BSAT-4a are ready for launch, as well as the Spaceport’s infrastructure and the network of downrange tracking stations.

With approval granted, Ariane 5 is cleared for its September 4 rollout from the Final Assembly Building to the ELA-3 launch zone. Liftoff will occur the following day during a 33-minute launch window that opens at 6:51 p.m. local time in French Guiana.

A heavy-lift delivery for Arianespace’s Ariane 5

Total payload lift performance for next week’s liftoff is approximately 10,838 kg., with the Intelsat 37e and BSAT-4a satellites being deployed to geostationary transfer orbit during a flight lasting 47 minutes. The mission is designated Flight VA239 in Arianespace’s launcher family numbering system, signifying the 239th with an Ariane family vehicle.

Positioned in Ariane 5’s upper passenger position and encapsulated by the launcher’s ogive-shaped payload fairing, Intelsat 37e – produced by Boeing – is the next satellite in Intelsat’s high-throughput EpicNG series for launch.

Weighing an estimated 6,440 kg. at liftoff, the spacecraft will provide capacity for wireless backhaul, enterprise VSAT and mobility networks, carrying out its mission from a 342-deg. East orbital slot.

BSAT-4a – Flight VA239’s lower passenger, contained in Ariane 5’s SYLDA dispenser system – is being launched by Arianespace as part of a turnkey contract between Japan’s Broadcasting Satellite System Corporation (B-SAT) and U.S.-based satellite manufacturer SSL.

To be operated from an orbital position of 110 deg. East, this spacecraft will be used for Direct-To-Home (DTH) television relay in Japan, as well as to expand the availability of advanced television services (such as 4K/8K ultra-high definition TV). BSAT-4a will weight approximately 3,520 kg. at liftoff.
