Ariane 5 | September 21, 2017

Arianespace Flight VA239: new launch date announced

During the original synchronized sequence of the final countdown, on Tuesday, September 5, 2017, an anomaly was observed with an electrical equipment in one of the Ariane 5 launcher's two solid-propellants boosters (EAP).

After identifying and replacing the electrical equipment, and having undertaken all the related checks, Arianespace has decided to resume the operations leading to the final countdown for Flight VA239.
This mission's liftoff is now planned on Friday, September 29, 2017 as early as possible within the following launch window:
 

[/li]
• between 5:47 p.m. and 6:25 p.m., Washington, D.C. time
• between 6:47 p.m. and 7:25 p.m., in Kourou, French Guiana
• between 21:47 and 22:25, Universal Time (UTC)
• between 11:47 p.m. and 00:25 a.m., Paris time during the night of Sept. 29 to 30
• between 6:51 a.m. and 7:25 a.m., Tokyo time on September 30.
  

This mission will orbit Intelsat 37e for the international operator Intelsat, and BSAT-4a for the manufacturer SSL (Space Systems Loral), within the scope of a turnkey contract with the Japanese operator Broadcasting Satellite System Corporation (B-SAT).

Ariane 5 | September 21, 2017

Ariane 5 is set for a September 29 liftoff with Intelsat 37e and BSAT-4a

Arianespace's ninth launch of 2017 is now scheduled for September 29 on a dual-payload Ariane 5 mission to geostationary transfer orbit with Intelsat 37e (for the global operator Intelsat) and BSAT-4a (for Space Systems Loral in the framework of a turnkey contract for the Japanese operator B-SAT).

Спойлер

Designated Flight VA239 in Arianespace's mission numbering system for its launcher family, the liftoff originally had been set for September 5, but was delayed after the countdown was stopped. An anomaly was detected with an electrical component in one of the Ariane 5 launcher's two solid boosters, which subsequently was replaced – allowing the launch vehicle's return to flight status.

Intelsat 37e will be the fourth EpicNG spacecraft orbited by Arianespace to date. Built by Boeing based on the 702MP platform, Intelsat 37e is the first satellite to offer interconnectivity between three different bands. It will deliver high-performance service in C-, Ku- and Ka-bands for use in wireless backhaul, enterprise VSAT and mobility networks.

Flight VA239's BSAT-4a satellite passenger will be utilized by B-SAT for Direct-to-Home (DTH) television service in Japan. Based on Space Systems Loral's SSL 1300 platform, BSAT-4a is equipped with 24 Ku-band transponders and will expand the availability of advanced television services such as high definition and 4K/8K ultra-high definition.

Ariane 5 | September 28, 2017

Ariane 5 is in the launch zone for Arianespace's mission with Intelsat 37e and BSAT-4a

The Ariane 5 for tomorrow's Arianespace flight with a pair of telecommunications satellites has moved to the launch zone at the Spaceport in French Guiana, positioning it for an evening liftoff to geostationary transfer orbit with the Intelsat 37e and BSAT-4a payloads.

Спойлер

For this ninth Arianespace mission of 2017, the Ariane 5's rollout occurred today – with the vehicle riding atop one of two operational launch tables for its return to the pad. Tomorrow's mission is designated Flight VA239 in Arianespace's numbering system for its launcher family, and will deliver a total payload lift performance of approximately 10,840 kg.

To be released first during the 47-minute mission will be Intelsat 37e – becoming the fourth EpicNG spacecraft orbited by Arianespace for Intelsat. This Boeing-built spacecraft, based on the 702MP platform, is the first to offer interconnectivity between three different bands. It is designed to deliver high-performance service in C-, Ku- and Ka-bands for use in wireless backhaul, enterprise VSAT and mobility networks.

Flight VA239's BSAT-4a passenger will be launched by Arianespace for satellite manufacturer Space Systems Loral in the framework of a turnkey contract with Japan's Broadcasting Satellite System Corporation (B-SAT). To be utilized for Direct-to-Home (DTH) television service in Japan, BSAT-4a is based on Space Systems Loral's SSL 1300 platform. The relay platform is equipped with 24 Ku-band transponders and will expand the availability of advanced television services such as high definition and 4K/8K ultra-high definition.

Galileo satellites are readied for Flight VA240 in December

In other activity at the Spaceport, the first two satellites for Arianespace's Flight VA240 with Ariane 5 have begun their checkout. Targeted for a liftoff on December 12 carrying a quartet of Galileo navigation spacecraft, this mission will be performed on behalf of the European Commission under a contract with the European Space Agency (ESA).
 

Two of the four Galileo satellites for Flight VA240 undergo their checkout processes at the Spaceport.

Arianespace already has launched 18 Galileo spacecraft, with four being deployed into medium Earth orbits on a previous Ariane 5 mission (Flight VA233 in November 2016), and the others lofted by seven medium-lift Soyuz vehicles carrying two satellites each.

Galileo is designed to provide a European global satellite navigation system with precision positioning services under civilian control.
