lasersSilicon and silica oxide nanomaterials would be best for laser pushed sail

0
California Institute of Technology researchers have worked out that super thin structures made of silicon and silica oxide convert waves of infrared light into a momentum that would accelerate a probe to speeds of around 60,000 kilometres (37,000 miles) per …

futureProof of concept lightsail material suitable for interstellar mission

0
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 …

futureProgress to stable laser propelled sails

0
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 …
