🌌 "To leave Earth behind, a rocket must reach 25,000 mph—the speed where gravity loses its grip."
A rocket escapes Earth by achieving escape velocity: about 25,020 mph (40,000 km/h)[citation:7]. Below that, gravity pulls it back into orbit. To generate this thrust, rockets burn propellant—fuel and oxidizer—expelling hot gases like a balloon releasing air[citation:7]. Larger planets require higher escape speeds: leaving Jupiter demands 133,100 mph[citation:7]. Staging helps rockets shed weight, discarding empty boosters to continue the journey[citation:7]. Once escape velocity is reached, even after propellant runs out, the rocket coasts away from Earth forever[citation:7]. This is why we can explore the Moon, Mars, and beyond. Let these quiet facts about rockets and space carry you into restful sleep.
