T he degree to which the Falcon 9, a rocket developed by SpaceX, dominates its competitors is not just unprecedented in space travel. It is unprecedented in more or less every field of human endeavour. In 2023 Falcon 9s launched over a thousand tonnes of payload into orbit, some 80% of the worldwide total. Whereas previous launchers rarely managed much more than ten blast-offs a year, Falcon 9s now leave their launchpads in California and Florida roughly ten times a month. The first stages of Falcon 9s have been successfully reused after returning from space and landing themselves more than 300 times. No other orbital launcher has managed such a thing even once.
