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 …

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 …
