Abstract: Establishing and growth of a lunar or planetary surface base involves continuing to use landing spacecraft as docked modules of the base for habitation and work. A first spacecraft is landed at a specified surface site then doubles as first module of the base. A second (and later third and subsequent) spacecraft is landed at the site a safe distance from the existing base modules then moved over the surface into a side-by-side position to dock with selected base modules. At least some of the landing, surface transport, and operational electric power is supplied by micro-fusion using ambient cosmic rays and muons interacting with deuterium-containing particle fuel material to generate energetic reaction products.

Abstract: A craft having a source of deuterium-containing micro-fusion fuel particles is operable above a planetary, lunar or asteroid surface in the presence of ambient cosmic rays. The fuel particles are dispersible from a set of ports, where at least some of the ports are in an underside of the craft body and others are in lateral sides of the craft body. Dispersed fuel particles interact with ambient cosmic rays and muons to generate energetic reaction products, at least some which are then received by the underside of the craft to generate lift and also selected lateral sides of the craft to generate propulsive thrust in a desired lateral direction. The craft can carry tethers and winches to carry a payload above the surface from location to another. In another embodiment, a balloon-based design, such as a dirigible, provides primary buoyant lift, while the micro-fusion particles provide at least lateral thrust, and supplemental lift where needed.

Each generator unit includes a source of deuterium-containing particle fuel material that can be supplied as a dispersed cloud in a columnar reaction volume. Ambient cosmic rays and muons entering the reaction volume interact with the dispersed fuel material to generate energetic reaction products that drive turbines coupled to electrical generators.

Abstract: A collision-avoidance propulsion system and method for orbiting satellites and other spacecraft takes advantage of ambient cosmic rays in space to catalyze micro-fusion events via particle-target fusion and muon-catalyzed fusion processes, using the reaction products to produce thrust upon orbiting satellites and other spacecraft. A supply of deuterium-containing particle fuel material is propelled in a specified direction of the spacecraft in response to indication of a potential collision with another space object (e.g. orbiting debris). In one embodiment, this may be performed by propellant gas expelling the fuel material through conduits to specified ports on the exterior of the spacecraft. The propelled material interacts with the ambient cosmic rays and muon generated from those cosmic rays to induce micro-fusion. A portion of the energetic reaction products (e.g. alpha particles) are received upon the spacecraft to alter its trajectory in a manner that avoids the potential collision.

Abstract: Asteroid redirection and soft-landing systems are provided that use cosmic ray and muon-catalyzed micro-fusion. These systems include a micro-fusion propulsion system providing thrust for redirecting a small asteroid, as well as providing a particle cushion at a landing site for a soft-landing. The systems deploy deuterium-containing fuel material as a localized cloud interacting with incoming ambient cosmic rays to generate energetic fusion products. Dust or other particulate matter in the fuel material converts some cosmic rays into muons that also catalyze fusion. The fusion products provide thrusting upon the asteroid. The fusion products also aid deceleration of incoming asteroids to be mined for a soft landing upon a lunar or planetary surface.

Abstract: A micro-fusion powered spacecraft makes use of ambient cosmic rays and muons generated therefrom to provide micro-fusion propulsion. The craft has a centrally located internal reaction chamber with an upper dome and tapering to a bottom exhaust opening. The chamber is radially surrounded by the main body of the craft. Ports from a fuel supply in the main body inject a deuterium-containing micro-fusion fuel material as a dispersed cloud into the chamber. Ambient cosmic rays and muons penetrate the upper dome into the chamber and interact with the fuel to produce energetic reaction products. Some of the reaction products exit the chamber through the exhaust opening to provide reaction thrust, while other reaction products interact with the dome of the chamber to directly apply a thrusting force. The exhaust system has a set electrostatic plates that deflect reaction products to steer the reaction thrust.

Abstract: A spaceplane and hybrid reaction engine employ micro-fusion enhanced propulsion in the presence of ambient cosmic rays and muons in the upper atmosphere at altitudes greater than 20 km. The reaction engines for the spaceplane may be of different types operable in different speed and altitude regimes, but at least one engine type incorporates a supply of deuterium-containing micro-fusion fuel that can be injected into the fuel mix along with the primary chemical fuel or into the exhaust in the nozzle section. The energetic fusion products from particle-target and/or muon-catalyzed fusion provide supplemental thrust for the spaceplane.

Abstract: A method, operable in the presence of ambient cosmic rays, is provided for braking a craft upon approach to a planet, moon or other space body, e.g. in preparation for landing. Deuterium-containing particle fuel material is projected in a specified direction outward of the craft, which interacts with both the cosmic rays and their principal decay product muons to generate energetic micro-fusion products that produce a braking thrust on the craft for a specified trajectory. The micro-fusion products may push directly against the craft, e.g. upon a pressure plate, or upon a sail or parachute connected to the craft, to decelerate the craft. A prepositioned automated landing system at a landing site may project the fuel material toward the craft based on telemetry tracking of an incoming craft and likewise directly disperse the material cloud to form a braking cushion at the landing site.

Abstract: A spacecraft propulsion method uses cosmic ray triggered nuclear micro-fusion events to provide repeated or continuous thrust for artificial gravity during a space flight. In one embodiment, successive packages of deuterium-containing micro-fusion particle fuel material is projected in a specified direction outward from a spacecraft. In another embodiment, the micro-fusion fuel material is a coating upon a set of angled rings arranged circumferentially around the spacecraft. In a third embodiment, the micro-fusion fuel is dispersed in proximity to “wind” turbines to generate electricity for ion thrusters. In each case, the material interacts with the ambient flux of cosmic rays to generate micro-fusion products having kinetic energy that either produce thrust upon the spacecraft or drive the turbines whose electrical output in turn powers the ion thrusters.

The spacecraft has means (such as a pusher mechanism) for receiving at least some portion of the generated kinetic-energy-containing products to produce thrust upon the spacecraft.

The micro-fusion generator systems deploy deuterium-containing fuel material as a localized cloud interacting with incoming ambient cosmic rays to generate energetic fusion products.

Abstract: A method is provided for heating or lighting a designated local area of a planet, moon or other space body in the presence of an ambient flux of cosmic rays by employing either or both muon-catalyzed or particle-target fusion of deuterium-containing fuel material. A series of packages of the fuel are directed to a location that is a specified distance from the local area to be heated or illuminated, for example at a specified altitude above that local area. The fuel material is then released, e.g. chemical explosive, to form a localized cloud that is exposed to and interacts with the ambient flux of cosmic rays and with muons generated from the cosmic rays. The resulting nuclear micro-fusion produces energetic reaction products together with usable heat and light radiating from the localized cloud of material.
