Space Team Europe for Ariane 6: Julien Guiridlian

Video: 00:02:19

They say it takes a village to raise a child. To launch a rocket, we have the combined expertise and passion of Space Team Europe. Julien Guiridlian is one of many making the first Ariane 6 launch possible and has been interviewed as part of a series highlighting some of the people that make up this dream team.

Working for France’s space agency CNES, Julien is Ariane launch complex assistant, which means he takes care of the ground segment for the combined tests on Europe’s new rocket. Julien takes care of coordinating everything from the fuel for the launcher, to ensuring there is electricity and the mechanical connections between the rocket and the launch pad. Ariane 6 is all about teamwork, and the team is ready for the match.

Space Team Europe for Ariane 6: Michel Bonnet

Video: 00:04:45

They say it takes a village to raise a child. To launch a rocket, we have the combined expertise and passion of Space Team Europe. Michel Bonnet is one of many making the first Ariane 6 launch possible, and has been interviewed as part of a series highlighting some of the people that make up this dream team.

“Who has not dreamed of working in the space sector?” he says, recalling how he built small rockets as a teenager using sodium chlorate, sulphur and sugar. In 1995, after years of work with helicopters and nuclear submarines, Michel started work in the space sector. For Ariane 6’s first flight, he is the Inaugural Flight Principal covering mission preparation, including the several small satellites being launched, and the launch campaign follow-up.

Michel is also head of a team of six engineers who are together working on the future possibilities for Ariane 6, often focussing on potential exploratory missions after 2030 and what modifications would be necessary to the launcher to make them feasible.

Trial by fire for Ariane 6’s upper stage

Video: 00:01:01

On 1 September 2023 ESA’s all-new Ariane 6 launch vehicle fired its two upper stage engines to simulate the way they will have to operate together at German aerospace agency DLR’s engine test centre in Lampoldshausen, Germany. The test – of the new Vinci engine and a smaller Auxiliary Power Unit (APU) – took place on a purpose-built test bench.

Vinci, the upper stage engine of Ariane 6 fed by liquid hydrogen and oxygen, can be stopped and restarted multiple times – to place satellites into different orbits and then de-orbit the upper stage, so it is not left behind as hazardous debris in space.

The APU makes it possible for Vinci to restart in space, by maintaining adequate pressure in the fuel tanks and preventing bubbles in the fuel lines. The power unit uses small amounts of liquid hydrogen and oxygen from the main tanks – replacing a system which relied on large quantities of tanked helium.

Ariane 6 is an all-new design, created to succeed Ariane 5 as Europe's heavy-lift launch system. This autonomous capability to reach Earth orbit and deep space is the foundation of Europe's vision of space-enabled navigation, Earth observation, scientific and security services. This vision is reality thanks to the sustained dedication of thousands of talented people working in ESA's 22 Member States who call themselves #SpaceTeamEurope.

ESA owns and manages the Ariane 6 programme and defines its performance objectives; ArianeGroup is the prime contractor, and launch operator is Arianespace. France's space agency, CNES, operates Europe's Spaceport in French Guiana – the home of Ariane launchers since the first liftoff in 1979.
