Laser-pushed lightsail starship, artwork. This starship's lightsail is 1000 kilometres across. The centre of the Milky Way galaxy is in the background. The starship is sailing away from two points of light at upper right. One is the Sun, while the greenish light near the Sun is a laser. An array of lasers near Mercury is redirected at the edge of the Solar System by a focusing fresnel lens that produces a single powerful coherent beam that can reach a distance of a few light years. This accelerates the starship to about 20 percent of the speed of light. Such a system could carry a cargo of many tons to other star systems.
