Interstellar Propulsion

Propelling human and robotic payloads to the stars is one of the most fantastic challenges facing mankind. The nearest star like our own, Alpha Centauri, is 4.3 light years away. That is roughly equal to twenty-four trillion miles! That may be a little difficult to comprehend. In a simplified comparison, think of the cup of coffee sitting next to you as the distance between the earth and the sun. In these relative terms the distance to Alpha Centauri would be roughly fifty miles away.
