The End of Free Skies | FAA Starts Charging for Rocket Launches

On April 22, 2026, the FAA published a final rule implementing per-launch user fees for commercial space transportation — the first time the U.S. government has charged payload-based fees for rocket launches. Starting at 25 cents per pound with a $30,000 cap, the fees are modest today. By 2033, they won't be.
