Researchers have proposed a new propulsion method that could make covering the vast distances required for interstellar missions feasible within a human lifetime.
The fundamental challenge in reaching a different star system lies in figuring out how to generate and transfer enough energy to a spacecraft both efficiently and affordably. The physical limitations of modern spacecraft pose significant challenges for reaching interstellar space in a human lifetime, especially with limited room onboard for carrying propellant or batteries. If we ever want to achieve the tremendous speeds necessary to cross interstellar distances in a human lifetime, we need to find outside-the-box solutions.
Enter relativistic electron beams made up of electrons moving close to the speed of light.
