Proof of concept lightsail material suitable for interstellar mission

Proposals using large light sails like the Starshot Breakthrough, require mirrors with lateral sizes of 4 × 4 m2, thicknesses of 0.05 lambda, reflectivities of 90 %, ppm level optical absorption and a total mass of only 1 gram. Photonics Crystal are designed with a lattice of holes which remove about 30 % of the …

Progress to stable laser propelled sails

Stable flight of a laser sail is an essential requirement of beam-driven propulsion. Centauri Dreams talked to James Benford about work towards stable beam flight. It places considerable demand upon the shape of the sail and beam. James Benford takes a hard look at where we are now in the matter of sail stability. He …
