For space, it all starts with rockets: they are the gateway to space.

This is what we do at ESA Space Transport. ⬇️

The first full-scale Phoebus oxygen tank is being made using automatic fibre placement technology.

The design is programmed into a machine, which lays down the carbon fibre tape, similar to how a sewing machine uses thread.

Carbon fibre reinforced plastics are a mix of two materials: the fibres and a plastic resin infused together.

But the difference lies in which threads are used, their composition and how they are weaved together.

Did you know not all carbon-fibre is created equal?

Carbon fibre used in racing cars is not the same grade as used in a phone case, for example.

And definitely not the same used on the Phoebus project!

And on that note...

The upper and the main stages have arrived in Kourou for the next Ariane 6 launch.

Time to build a rocket! 🚀

A modern cargo vessel named "Canopée" sails across calm waters under a clear blue sky. The ship features four prominent vertical structures which allow the use of wind-assisted propulsion technology. Positioned centrally in the frame, the vessel stands out against the serene ocean backdrop, highlighting a blend of traditional maritime transport with innovative, sustainable design elements. A large container marked is being carefully unloaded from the Canopée vessel at the Port de Pariacabo. The container, housing Ariane 6's Upper Stage, is being transported by a blue truck. Several workers in high-visibility gear are present, coordinating the logistics of this complex operation. Inside a spacious industrial facility, a Ariane 6's Upper Stage is being carefully transported on a heavy-duty vehicle. The scene includes several personnel in safety gear, one prominently wearing a blue shirt, overseeing the operation. The facility’s high ceilings, metal framework, and bright lighting underscore its suitability for handling large and sensitive space hardware.

Ariane 6’s metallic nozzles have advanced cooling: over a thousand small cooling channels run through the nozzle’s millimetre-thin wall.

These channels allow the flow of liquid hydrogen, which helps maintain the nozzle’s structural integrity by cooling it down.

Inside an aerospace facility, a cylindrical metallic structure, part of the Vulcain 2.1 engine nozzle extension for Ariane 6, is positioned on a bright orange support base. 

The component features finely machined horizontal ridges and is surrounded by robotic arms and cables, indicating active manufacturing or testing.
The environment includes control panels and technical equipment, reflecting the precision and complexity of modern space propulsion engineering.

Nozzles direct the thrust and flow of exhaust gases during launches.

This means lots of heat, as exhaust temperatures can reach up to 4000 ºC.

In a high-tech industrial setting, a large ribbed cylindrical component, part of the Ariane 6 main engine nozzle, is suspended by an overhead crane system. A technician stands nearby, operating a control device and monitoring the process. The environment is filled with precision machinery and equipment, highlighting the advanced engineering and careful handling required in aerospace component manufacturing.

Sweden is not only an @esa.int founding member and a host of the Esrange Space Centre in Kiruna, but also an important contributor of Ariane 6.

GKN Aerospace, based in Sweden, provides turbines and nozzle extensions for Ariane 6's rocket engines.

An infographic celebrating Sweden’s role in the Ariane 6 rocket programme. 

At the top, the ESA logo is prominently displayed above the title “Ariane 6 Made in Sweden.” 

The graphic highlights Sweden’s 1.5% contribution to the programme, emphasising its involvement in building Europe’s most powerful rocket. A detailed illustration of the Ariane 6 rocket is shown, with callouts identifying Swedish-made components: turbines for the Vinci engine and both turbines and nozzle extension for the Vulcain 2.1 engine, all produced by GKN Aerospace. 

A map of Europe at the bottom right pinpoints Sweden and visually connects it to other parts of the continent, accompanied by a Swedish flag.

Contract for a reuseable upper stage demonstration mission signed at IAC ✍️

@esa.int and Avio signed a contract for 24-months of development activities aiming at the in-flight demonstration of a reusable upper stage.
A ceremonial contract signing event is taking place, highlighting a collaboration on the "Reusable Upper Stage Demonstrator Activities." Two key representatives: ESA's Director of Space Transportation Toni Tolker-Nielsen (left) and Avio’s Chief Commercial Officer and Launch Services Director Marino Fragnito (right), both seated at a table, signing the agreement. The table is decorated with miniature flags symbolising international cooperation. ESA's Chief Technical Advisor for Space Transportation Giorgio Tumino stands nearby, observing the proceedings. Behind them, a large screen displays the event title and participant names, with ESA and AVIO logos, along with a commemorative emblem marking ESA’s 50th anniversary in 2025. The setting conveys a formal and significant milestone in space transportation development.

The views are unmatched ✨

This is an aerial view of Europe's Spaceport in Kourou, French Guiana - our home to the ESA-developed rocket families of Ariane and Vega.

500 km north of the equator, rockets gain extra performance thanks to a ‘slingshot effect’ from the speed of Earth’s rotation.
