Preparations are underway for Arianespace's upcoming Vega and Ariane 5 missions

A pair of important arrivals this week - one by air, the other by sea - marked an acceleration of preparations at Europe's Spaceport for Arianespace's next two missions, to be performed from French Guiana with its lightweight Vega and heavy-lift Ariane 5 launch vehicles.

These parallel arrivals involved personnel who will conduct the first Vega "rideshare" mission, scheduled for mid-June to orbit 53 small satellite payloads; and Ariane 5 launch vehicle components for a three-passenger flight planned for liftoff this summer.


... main launcher components for the Ariane 5 flight were being unloaded from the MN Toucan, one of two roll-on/roll-off sea-going ships operated for Arianespace, which docked at Paricabo Port near Kourou. After unloading, the components were to be taken by road to the Ariane 5's ELA-3 launch complex - also situated on the Spaceport's Kourou side.

Launch activities in French Guiana had been suspended mid-March because of the COVID-19 pandemic, and were gradually resumed - carried out in strict compliance with health rules published by the Prefect of French Guiana, as well as the French CNES space agency and the Guiana Space Center.


Readying Ariane 5's three-satellite payload

For Arianespace's initial Ariane 5 mission following the resumption of operational activity at the Spaceport, its heavy-lift launcher will carry three payloads to geostationary transfer orbit: the Galaxy 30 and BSAT-4b telecommunications satellites, along with a Mission Extension Vehicle (MEV).

Riding in Ariane 5's upper payload position will be Galaxy 30, produced by Northrop Grumman Innovation Systems (NGIS). This is the first spacecraft built under Intelsat's North American satellite fleet replacement program and highlights the operator's continued focus on C-band communication technologies.

To be deployed as a Galaxy 30 "piggyback" payload is Northrop Grumman's second Mission Extension Vehicle (MEV-2) - a servicing spacecraft that docks with an existing satellite in orbit to provide life-prolonging propulsion and attitude control. After deployment by Ariane 5, MEV-2 will service the Intelsat 10-02 satellite, which was launched in 2004.

Flight VA253's other passenger on Ariane 5 - BSAT-4b - was built by Maxar Technologies for Japan's Broadcasting Satellite System Corporation (B-SAT) as a back-up to BSAT-4a, launched by Arianespace in 2017. BSAT-4b uses Maxar Technologies' 1300 Class platform and carries Ku-band transponders.

We've postponed Vega Flight #VV16 until Aug. 17, when the forecast for high-level winds should be more favorable on the northward trajectory of this rideshare mission.

Next up: Ariane 5 Flight #VA253, planned for July 28 w/ @Intelsat 's Galaxy 30 & MEV-2, and B-SAT's BSAT-4b

A double arrival of Galaxy 30 and MEV-2 for Arianespace's next Ariane 5 mission

During operations at Félix Eboué Airport, Galaxy 30 and Mission Extension Vehicle-2 (MEV-2) are unloaded from the cargo jetliner that transported them to French Guiana for Arianespace's Flight VA253 launch with Ariane 5.

The two payloads that will ride together on Arianespace's upcoming Ariane 5 heavy-lift mission have arrived at the Spaceport in French Guiana to begin their pre-launch processing.

Delivered aboard an Antonov An-125 cargo jetliner last weekend were the Galaxy 30 relay satellite for Intelsat, along with the Mission Extension Vehicle-2 (MEV-2) - a pioneering satellite servicing spacecraft designed to dock with orbiting geostationary satellites whose fuel has nearly depleted.

They were unloaded from the aircraft at Félix Eboué Airport near the capital city of Cayenne for transfer by road to the Spaceport.

Two Northrop Grumman payloads for Flight VA253

Galaxy 30 and MEV-2 will be lofted on the next Ariane 5 mission - designated Flight VA253 in Arianespace's launcher family numbering system - along with the BSAT-4b satellite for Maxar. Liftoff of Flight VA253 is scheduled for the end of July.

The Galaxy 30 spacecraft was built by Northrop Grumman, while MEV-2 was supplied by Space Logistics LLC, a wholly owned Northrop Grumman subsidiary. They will be stacked together to ride in the upper payload position on Ariane 5 for its mission to geostationary transfer orbit.

The Mission Extension Vehicle-2 will be deployed by Ariane 5 for its rendezvous and docking with the Intelsat 1002 satellite, which is scheduled for early 2021. Intelsat 1002 was launched in 2004 by Arianespace, and the MEV-2 will use its own thrusters and fuel supply to control the satellite's orbit, thereby extending its useful lifetime.

Multi-band relay duties for Galaxy 30

Galaxy 30 is based on Northrop Grumman's flight-proven GEOStar-2 platform. As the 11th Northrop Grumman satellite purchased by Intelsat, it is the first in Intelsat's Galaxy fleet replacement program, dedicated to video distribution and broadcast services. With a C-band payload, this spacecraft will be integral to the U.S. C-band spectrum transition plan, on which Intelsat is collaborating with the U.S. Federal Communications Commission.

Additionally, Galaxy 30 has Ku- and Ka-band payloads to support broadband applications, as well as the Wide Area Augmentation System (WAAS) hosted payload for the Federal Aviation Administration. WAAS is an extremely accurate navigation system for civil aviation.
