Though it is a very powerful machine, it is not the most powerful. Saturn V rocket and LHC still hold those accomplishments. Catching a rocket in mid-air is very impressive though.
Incorrect Starship is more powerful than the Saturn V.
Thrust:
Saturn V: At liftoff, the Saturn V produced approximately 34.5 million newtons (7.7 million pounds) of thrust.
Super Heavy-Starship: The Super Heavy booster, when using all Raptor engines at full thrust, is designed to produce around 75.5 million newtons (17 million pounds) of thrust. This makes the Starship system significantly more powerful in terms of thrust at liftoff.
Payload to Low Earth Orbit (LEO):
Saturn V: Could deliver about 118 metric tons to LEO.
Super Heavy-Starship: SpaceX aims for a payload capacity of up to 150 metric tons to LEO, though this figure is subject to change as the system's development progresses.
Payload to the Moon:
Saturn V: Managed to send around 48.6 metric tons to lunar orbit for the Apollo missions.
Super Heavy-Starship: While exact figures for lunar missions are still speculative, the system's design suggests it could carry significantly more than the Saturn V, potentially over 100 metric tons to translunar injection.
