Abstract: Dr. Lubin will discuss how his team has proposed an orbital planetary defense system that is capable of beamed power allowing a number of directed energy (DE) possibilities including planetary defense, propulsion allowing relativistic probes and interstellar communications using existing technologies. Recent developments in photonics allow such a system whereas even a decade ago it would have been simply science fiction. . . .
