Sunbeam: Near-Sun Statites as Beam Platforms for Beam-Driven Rockets

We outline a method of beamed power for propulsion that utilizes relativistic electron beams. The physics of charged particle beam propagation in the space plasma environment is discussed and the long-range (>100 A.U.) advantage of relativistic electron beams is emphasized. A preliminary statite based beam emitter for powering probes to ~0.1c is proposed and the challenges in beam-power uses are explored.

The Benefits of Spin Polarization for Inertial and Magneto-Inertial Fusion Propulsion

Spin-polarized fusion has the potential to lower the radiation shielding and ignition requirements for fusion rockets while simultaneously increasing the fusion fuel burnup and provide better momentum coupling to a spacecraft. This potential is estimated using simple, analytic techniques. Both DT and D\textsuperscript{3}He fusion fuels are analyzed.
