photonic propulsionUsing Spacex BFR to rapidly and affordably build interplanetary photonic railway by the 2030s

The Lubin UCSB laser propulsion system efforts have been funded by Breakthrough Starshot for $100 million. They are working working to demonstrate proof of concept for light-propelled nanocrafts. A large scale network of several 70 Gigawatt lasers on Earth, Earth …

futureDirected Energy Propulsion has made a lot of experimental progress

Philip Lubin, University of California, Santa Barbara, Directed Energy for Interstellar Study Starting at 26 minutes of this video. They are making progress with laser locking over kilometer distances. They are making 2 gram starchip prototypes. they are looking at …

futureProof 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 …

futureProgress 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 …

energyNASA Concept to use 100 MW beamed power for ion drive that is 20 times better

John Brophy at NASA Jet propulsion laboratory combines a near term 100 megawatt laser beamed power system to enable an ion drive with 70 megawatts of power and 58000 ISP. They propose a new power/propulsion architecture to enable missions such …
