SUMMARY
Rockets turn horizontally shortly after launch primarily to minimize gravity drag and optimize energy efficiency during ascent. The initial vertical ascent is necessary to counteract gravity, but transitioning to a horizontal trajectory early allows rockets to achieve orbital velocity more effectively. This method reduces aerodynamic pressure and structural loads, as the atmosphere thins rapidly at higher altitudes. The gravity turn maneuver is essential for balancing thrust and minimizing energy waste during the launch phase.
