energyGame Changing Direct Drive Fusion Propulsion Progress

Direct Fusion Drive, is a unique fusion engine concept based on the Princeton Field-Reversed Configuration (PFRC) fusion reactor under development at the Princeton Plasma Physics Laboratory. The truly game-changing levels of thrust and power in a modestly sized package could …

materialsA SpaceCraft Could Get to 430,000 Miles From the Sun Using Proposed Coating

In 2018 the Parker Solar Probe launched and plans to approach the Sun to within 8.5 solar radii (4 million miles) of its surface. This is seven times closer than any previous mission. Researchers think a new coating could allow …

cubesatImproved Solar Sail

The conventional means of collecting and redirecting solar sail light uses a metal-coated polyimide film but this is sub-optimal and unstable because the very large and very thin sail must be rapidly slewed away from the sun line for navigational …

physicsMass Beam Propulsion

Gerald Nordley provided a mass beam propulsion overview at Space Access 2019. There have been many kinds of mass beam propulsion. Use of mass beams, instead of light, allows great efficiency by adjusting the beam velocity so the redirected mass …

newsUltrahigh Acceleration Neutral Particle Beam Driven Sails

James Benford presents his Ultrahigh Acceleration Neutral Particle Beam-Driven Sails at Space Access 2019. The Neutral Particle Beam-Driven Sails could enable an interstellar probe to alpha centauri that would be 1000 times larger and 60% of the speed of the …

Positron Dynamics will use Krypton isotopes to generate positrons and catalyze fusion propulsion. #SpaceAccess2019

newsQ Drive to Use Power of Solar Wind for Braking With Reaction Mass

Jeff's new idea is to take the energy from the passage through the plasma of space to use on the reaction mass that a spacecraft is carrying. This the Drag-powered reaction: Q-Drive. #SpaceAccess

electric sailThrust Vectoring of an Electric Solar Wind Sail

The electric solar wind sail is a propulsion system that uses the solar wind proton flow as a source of momentum for spacecraft thrust. The momentum of the solar wind is transferred to the spacecraft by electrically charged light-weight tethers …
