Photon rocket

A photon rocket is a type of spacecraft made up of a rocket and a device called a photon drive. The photon drive helps the rocket fly further and faster into space by shooting out beams of light, called photons. As the photons move away from the rocket, they create a push on the rocket, like a tiny gust of air pushing it forward. This pushes the rocket faster and farther, helping it reach its destination faster.
