Rockets turn horizontally shortly after launch to minimize gravity drag and optimize energy use during ascent. While gaining altitude is essential, achieving horizontal speed quickly reduces the time spent fighting against gravity, which is crucial for efficient flight. The initial vertical ascent helps to minimize atmospheric drag, but a rapid transition to horizontal thrust allows rockets to utilize their powerful first-stage engines effectively. This method balances the need for both kinetic and potential energy, as the rocket must achieve significant speed and altitude to maintain orbit. Overall, the gravity turn technique is designed to maximize efficiency and structural integrity during launch.
