ESTEC’s new Galileo payload testbed facility

ESA microwave engineers took apart an entire Galileo satellite to reassemble its navigation payload on a laboratory test bench to run it as though it were in orbit – available to investigate the lifetime performance of its component parts, recreate satellite anomalies, and test candidate technologies for Galileo’s future evolution.

New technology version of EGNOS will harness Galileo for aviation

EGNOS V3 Contract signing

EGNOS V3 Contract signing

The next generation of Europe’s satellite navigation overlay service, EGNOS, will combine use of GPS and Galileo signals to improve accuracy and robustness of navigation for air traffic and other uses where lives are at stake.

A contract was signed on 26th January at ESA’s technical centre in the Netherlands for the second  generation  of the European Geostationary Navigation Overlay Service, EGNOS V3, planned to enter service in 2025. Read more…

ESA proves new technologies to power future launchers

Expander-cycle Technology Integrated Demonstrator

Expander-cycle Technology Integrated Demonstrator

A full-scale demonstrator of the thrust chamber for an upper-stage rocket engine incorporating the newest propulsion technologies is being prepared for its first hot firing.

The Expander-cycle Technology Integrated Demonstrator, or ETID, has arrived at the DLR German Aerospace Center test facility in Lampoldshausen for tests. It will help to prove new technologies, materials and manufacturing techniques that offer higher performance at lower cost for Europe’s future launchers.

ETID is a precursor of the next generation of 10-tonne rocket engines. Some of the technologies could also be used on upgrades to the existing Vinci, which powers the upper stage of Ariane 6. Read more…

Building Ariane 6 mobile gantry at Europe’s spaceport

Ariane 6 launch zone

Ariane 6 launch zone

The first structural element of the mobile gantry that will house and protect Ariane 6 before launch has been assembled.

The mobile gantry is a 90 m-high, nine-storey structure weighing 8200 tonnes. Riding on rails, it is retracted before launch.

Work platforms will enable engineers to access the vehicle levels to vertically position Ariane 6’s central core directly on the launch table, add two or four boosters depending on the launch configuration, and integrate the fairing that houses the payload. Read more…

Ariane 6’s Vulcain engine set for first firing

Vulcain 2.1

Vulcain 2.1

A Vulcain rocket engine recently arrived in Germany ahead of its first test firing in December to demonstrate new capabilities and technologies developed for Ariane 6.

The Vulcain 2.1 will help to propel Ariane 6, new-generation launcher for Galileo, in the first 10 minutes of flight, up to an altitude of 200 km.

The engine delivers 135 tonnes of thrust in vacuum, and weighs the same as an Airbus A318 jet engine but provides more than 10 times the power. Read more…

[vid] Galileo Launch 9 liftoff replay

Europe has four more Galileo navigation satellites (satellites 19–22) in the sky following their launch from Europe’s Spaceport in Kourou, French Guiana at 18:36 GMT (19:36 CET, 15:36 local time), on an Ariane 5 rocket, operated by Arianespace.

 

Galileo launch brings navigation network close to completion

Liftoff of Ariane 5 Flight VA240 from Europe’s Spaceport in Kourou

Europe has four more Galileo navigation satellites in the sky following their launch on an Ariane 5 rocket. After today’s success, only one more launch remains before the Galileo constellation is complete and delivering global coverage.

Ariane 5, operated by Arianespace under contract to ESA, lifted off from Europe’s Spaceport in Kourou, French Guiana at 18:36 GMT (19:36 CET, 15:36 local time), carrying Galileo satellites 19–22. The first pair of 715 kg satellites was released almost 3 hours 36 minutes after liftoff, while the second pair separated 20 minutes later. Read more…
