A rocket engine produces thrust by reaction to exhaust expelled at high speed. Unlike jet engines, rockets are fuelled entirely by propellant which they carry, without the need for oxygen from air; consequently a rocket can fly in the vacuum of space, indeed rocket engines operate more efficiently outside the atmosphere.

AI overview

A rocket is an elongated vehicle powered by a rocket engine that expels exhaust at high speed to create thrust, allowing it to fly even in the vacuum of space where there is no air. Rockets matter because they carry all their own fuel and don't need oxygen from the air to operate, making them uniquely capable of reaching space and beyond, unlike jet engines that depend on atmospheric air.
