“…The NOVA laser of Lawrence Livermore National Laboratory and VULCAN laser of Rutherford Appleton Laboratory have demonstrated the feasibility of photofission using uranium-238 [10]- [12]. Tabletop laser systems achieving the ultra-intense laser have been established for producing photofission of a uranium-238 target [12].…”

“…Noted by Naik et al the determination of photofission energy yield for uranium-238 is an evolving scientific subject pending convergence [15]. The photofission energy yield ratio developed by LeMoyne and Mastroianni utilizes the experimental findings that 7 × 10 4 fissions per joule of the ultra-intense laser are feasible [2] [10] [12].…”

“…These multiple sources affecting the research and development of laser devices likely promotes considerable promise for the correlated evolution of ultra-intense laser systems. Ultra-intense lasers on the scale of 10 20 W/cm 2 have generated sufficient bremsstrahlung photons to achieve photofission through institutions, such as Lawrence Livermore National Laboratory's NOVA laser and Rutherford Appleton Laboratory's VULCAN laser [10]- [12].…”

Project New Orion entails a pulsed nuclear space propulsion system that utilizes photofission through the implementation of an ultra-intense laser. The historical origins derive from the endeavors of Project Orion, which utilized thermonuclear devices to impart a considerable velocity increment on the respective spacecraft. The shear magnitude of Project Orion significantly detracts from the likelihood of progressive research development testing and evaluation. Project New Orion incorporates a more feasible pathway for the progressive research development testing and evaluation of the pulsed nuclear space propulsion system. Photofission through the application of an ultra-intense laser enables a much more controllable and scalable nuclear yield. The energy source for the ultra-intense laser is derived from a first stage liquid hydrogen and liquid oxygen chemical propulsion system. A portion of the thermal/kinetic energy of the rocket propulsive fluid is converted to electrical energy through a magneto-hydrodynamic generator with cryogenic propellant densification for facilitating the integral superconducting magnets. Fundamental analysis of Project New Orion demonstrates the capacity to impart a meaningful velocity increment through ultra-intense laser derived photofission on a small spacecraft.
