How is a launch window defined?
It isn't chosen. It's calculated.
Every launch begins long before countdown.
Engineers calculate the precise moment when the launcher's trajectory, Earth's rotation and the mission's orbital requirements all come together.
That moment becomes the launch window: the period during which liftoff will place the satellite on the right path to its destination.
Behind every countdown lie months of calculations, simulations and mission planning.

Why does launch happen at a specific time?
Every mission is designed to place its satellite into a precise orbit.
A launch window defines the period during which the launcher can lift off while meeting the mission's orbital requirements.
Outside that window, the planned trajectory can no longer be achieved.
Because every second counts when your destination is space.

📅 Save the date: August 27, 2026.
On August 27, Arianespace will launch MTG-I2 aboard Ariane 62 from Europe's Spaceport in French Guiana.
Developed through the long-standing partnership between ESA and EUMETSAT, MTG-I2 is part of Europe's next-generation geostationary meteorological satellite system. It will provide enhanced imagery to support the early detection of rapidly developing severe storms, weather forecasting and climate monitoring.
Designated VA270, this mission will mark Ariane 6's fourth launch of the year and its first mission to geostationary transfer orbit.
Stay tuned as we prepare for launch.

🚀 SUCCESS.
36 Amazon Leo satellites deployed.
🔥 First flight with P160C boosters.
📦 Heaviest payload ever launched by an Ariane launcher.
📈 The biggest Amazon Leo stack ever launched to date
With VA269, Ariane 6 has now launched 100 Amazon Leo satellites in just five months.
A new milestone for Ariane 6 and for Amazon's low Earth orbit constellation.
