Why Rockets Curve After Launch: The Physics of Fuel Efficiency

Every rocket that has ever left Earth has told the same quiet lie: it appears to defy gravity, yet it survives only by surrendering to it. The curving arc that follows a vertical launch is not a flaw in the design but a negotiation with the fundamental forces of the cosmos — a spacecraft learning, in real time, to fall sideways fast enough to miss the planet entirely. From the earliest orbital missions to Artemis II's journey toward the moon, this gravity turn has remained humanity's most elegant answer to the question of how fragile machines and mortal crews can slip free of a world that neve
