Google AI:
SpaceX’s Raptor 3 engine eliminates the need for a separate heat shield by integrating advanced regenerative cooling and internalizing fluid paths, allowing exposed components to cool themselves with liquid methane, which significantly reduces weight, complexity, and cost, enabling higher performance and payload for the Starship. This “clean” design means small fuel leaks burn off safely in the superheated plasma, improving reliability and boosting overall efficiency.
