Would propellers work in space

Propellers would not work in space because they rely on the presence of air to generate thrust through the movement of blades. In the vacuum of space, there is no air or atmosphere to create the necessary lift. Instead, spacecraft use rocket engines that expel gas at high speed to produce thrust, adhering to Newton's third law of motion. Thus, while propellers are effective in atmospheric conditions, they are impractical for the vacuum of space.
