The European Ariane 6 rocket has set a new record by deploying 36 Amazon Leo satellites into orbit – more than ever before on a single mission. At first glance, this may look like a purely technical achievement. However, it reflects something broader: Europe’s return as an independent actor in the space race, intensifying competition between Amazon […]
