🚀 A single Prometheus® engine is designed to be reused up to 5 times, with multiple ignitions possible during a mission and across successive flights.
Which aspect of reusability impresses you most: durability, multiple ignitions or cost reduction?

Ordinary fabric in, rocket-grade carbon fibre out. ArianeGroup is the only manufacturer of Xrayon®, made in a ~10m furnace, patiently transformed step by step. 🚀

In space, every kilogram counts. ArianeGroup builds composite structures, stacked carbon layers + aluminium honeycomb, rigid, lightweight, built at Le Haillan. 🚀

Ariane 6’s 10th flight is on the horizon. 🚀
ARIANESPACE is preparing VA271, with 36 Amazon Leo satellites aboard an Ariane 64, from Europe’s Spaceport in French Guiana. Liftoff is currently targeted for no earlier than November 23.

🚀 VA271 – LE-04 : Ariane 6's 10th flight is on the horizon!
Arianespace is preparing to launch 36 Amazon Leo satellites aboard Ariane 64 from Europe's Spaceport in French Guiana. Liftoff is currently targeted for no earlier than November 23.
This will be the fourth Ariane 6 mission for Amazon Leo, bringing the total number of satellites launched by Arianespace for the constellation to 136, upon successful completion.
For this mission, Ariane 6 will fly in its most powerful configuration, with four P160C solid rocket boosters.
Another step in Ariane 6's operational ramp-up and our continued partnership with Amazon to help bring connectivity to more people around the world.

🚀 The launch window is set.
The launch window is now confirmed for Ariane 6's next mission, dedicated to the launch of the MTG-I2 satellite.
Liftoff is scheduled for August 27, 2026, from Europe's Spaceport in French Guiana, within the following window:
- 16:10 – 18:40 (Washington, D.C.)
- 17:10 – 19:40 (Kourou)
- 20:10 – 22:40 (UTC)
- 22:10 – 00:40 (Paris - August 28)
Launching aboard Ariane 6, MTG-I2 will strengthen Europe's next-generation geostationary meteorological satellite system, providing enhanced imagery for the early detection of severe storms, weather forecasting and climate monitoring.
Designated VA270, this mission will be Ariane 6's fourth launch of the year and its first mission to geostationary transfer orbit.
The launch campaign is underway. Stay tuned.

🪐 Reaching Mars is only part of the challenge.
For ExoMars, protecting the spacecraft during atmospheric entry is just as critical. ArianeGroup contributes with Norcoat® Liège HPK.
Hardest phase: launch, cruise, entry or landing?

World Space Week 2026 is here, celebrating this year's theme: "Rocket Revolution."
Over 45 years, 6 generations, one ambition: keep Europe's access to space independent.
🚀 Ariane 1 (1979) - Capable of placing nearly 1,850 kg into geostationary transfer orbit. It marked the beginning of Europe's autonomous access to space.
🚀 Ariane 2 (1986) - A shorter chapter, but an important one: upgraded engines and a longer cryogenic third stage paved the way for greater performance.
🚀 Ariane 3 (1984) - Boosted with solid propellant strap-ons, extending what the early Ariane family could carry.
🚀 Ariane 4 (1988) - The workhorse. 116 launches, only 3 failures, and more than 180 satellites carried into orbit over 15 years, one of the most reliable launchers of its era.
🚀 Ariane 5 (1996) - The legend. 117 flights, a 98.4% reliability rate, and a role in some of space exploration's defining missions: the Rosetta comet probe, the BepiColombo mission to Mercury, and the launch of the James Webb Space Telescope on Christmas Day 2021.
🚀 Ariane 6 (2024) - The new generation, carrying that legacy forward with a reignitable upper stage for greater mission flexibility.
Which one is your favorite?

Space used to be for a few. Now startups, universities and new space nations are in too. "Rocket Revolution" is this year's World Space Week theme. We build the launchers that keep that access open for Europe. 🚀

ExoMars, born from three missions: Beagle2 (2003), Huygens (2005), Schiaparelli (2016). Each one built ArianeGroup's expertise in atmospheric entry.
Today, that heritage protects Rosalind Franklin's 3.80-metre shield, the largest ever built in Europe. 🛡️

The closer to launch, the less room for surprises. In the final minutes, everything runs on an automated sequence: safety barriers lifted, battery switch, engine ignition. One parameter out of range stops it all. 🚀

Don't bring Earth to Mars.
Rosalind Franklin searches for signs of life on Mars, so it must not carry any of its own from Earth. In ArianeGroup's clean room, both visible particles and invisible micro-organisms are tracked and eliminated before the thermal shield ever leaves for space. 🦠
💬 Which do you think is harder to control: a visible particle, or an invisible micro-organism?
#RocketMakers #Civil #ExoMars
Built to survive Mars. But first, it has to prove it.
ArianeGroup tests its thermal protection with SIMOUN, an artificial furnace powerful enough to recreate Mars's extreme heat. It's also bent, shaken, and checked piece by piece. 🔥

🚀 Why doesn't Ariane 64 fly straight up?
Because it would waste energy.
A launcher doesn't just need altitude.
It needs the right trajectory. 🧵
For Ariane 64, every part of the flight profile is designed around the mission's needs:
- payload mass
- target orbit
- launcher configuration
- performance margins
🚀 Ariane 64 doesn't turn early by accident.
It follows a carefully designed trajectory to use its power efficiently and deliver Europe's most demanding missions.
