The present invention generally is a system and method for ground, atmospheric and space based solar powered electrical energy generation and transmission of beamed microwave power. Specifically it is a system and method for generating electrical energy from a plurality of photovoltaic cells dispersed on a flexible surface each in close proximity to and functionally connected to microwave generating and transmitting means for controllably forming one or more stronger microwave beams by combining a plurality of much weaker individual microwave beams. The invention can be a microwave beam weapon for detecting and transferring microwave energy to non-cooperative targets or it clear orbital debris by momentum transfer to space object through microwave radiation pressure. Most practically it can provide electric power and microwave beam weapon defense to remote military and civilian facilities, including forward operating bases.

The present invention relates to an aerospace vehicle comprising an airplane or spacecraft, operatively coupled to an airship balloon containing lighter than air gas adapted to elevate the vehicle. A control system adapted to deflate the balloon upon reaching a predetermined altitude by directing the gas for powering the vehicle at greater speed. The balloon can be re-inflated for decreasing the speed of the vehicle upon reaching a destination and deflated in a controlled manner for landing the vehicle or disengaged from the vehicle upon transferring the gas from the balloon to a propulsion system of the vehicle.

Various embodiments provide for Corrugated Rollable Tubular Boom (COROTUB) designs. Various embodiments provide a new thin-shell tubular mast design, specifically COROTUB designs, that have unique corrugation features enabled in part by shells only affixed to each other at two respective cross-sectional end web regions.

A transportation network for providing propellant in space can include optical mining vehicles that concentrate solar energy to spall captured asteroids, capture released volatiles, and store them in reservoirs as propellants. The network can also have orbital transfer vehicles that use solar thermal rocket modules that focus solar energy on heat exchangers to force propellant through nozzles, as well as separable aeromaneuvering tanker modules with reusable heatshields and storage tanks. The network can have propellant depots positioned between Earth and a transport destination. The depots can mechanically couple to accept propellant delivery and to supply it to visiting space vehicles.

A spacecraft reaction control system comprising: a spacecraft having a center of mass; a length of tether extending from said spacecraft and offset from said spacecraft's center of mass and means for controllably changing said extension of said offset such that a variable force is exerted upon said spacecraft by said tether, said force being offset from said center of mass.

Systems for insulating a space vehicle or space borne container from an external environment as well as cryogens from heat sources. Such systems also protect the vehicle from the high dynamic pressures, the high heat loads encountered in atmospheric flight, and provide storage capability that strongly limits, or effectively eliminates, cryogenic boil-off losses once in space. Such systems include an expandable structure having a plurality of contiguously adjacent expandable layers. The layers are connected by a plurality of tension connectors between successive layers. For launch and flight the layers can be restrained in a collapsed position. Whereupon exiting a free stream environment, the layers are expanded where they can lock into place or otherwise remain in an expanded state. The expansion creates separation between the layers with minimal conduction paths providing near theoretically perfect multi-layer insulation and extremely effective debris protection.

Solar collectors can provide power for electricity, thermal propulsion, and material processing (e.g., mining asteroids). In one aspect, a rocket propulsion system is configured to produce thrust for a spacecraft and includes: one or more optical elements configured to receive solar energy. The optical elements include: a first window configured to allow energy to enter the rocket propulsion system and form a concentrated energy beam, and a second window positioned to allow the concentrated energy beam to pass to the heat exchanger. The second window is spaced away from the first window to form a pressurized plenum chamber therebetween. The system further includes: a heat exchanger configured to receive the energy and use it to heat and pressurize a propulsion gas, and a rocket nozzle configured to expel the pressurized propulsion gas.

Exemplary embodiments described herein include innovative engagement devices. Exemplary engagement devices may include on or more tape spring systems. The tape spring system may include a continuous or segmented bi-stable tape spring. The tape spring can be stowed in a rolled up configuration, extended to a deployed configuration, and then triggered to return to a retracted configuration.

An earth to space transport method, system and apparatus. The earth to space transport system can include a main body; a plurality of storage tanks disposed in an inside of the main body, the storage tanks configured to store helium; one or more electric jet propulsion turbines coupled to the main body; a first inflatable cushion disposed at a top of the main body and a second inflatable cushion disposed at a bottom of the main body; a space capsule disposed above the first inflatable cushion; a power generator; and a rotor propeller. Such an earth to space transport system may be utilized to efficiently move humans, satellites and cargo from earth to space.

Solar collectors can provide power for electricity, thermal propulsion, and material processing (e.g., mining asteroids). In one aspect, an apparatus for collecting solar energy and simultaneously protecting against damage from a resulting energy beam includes a solar energy collection system including at least one concentrator and a target configured to use, store, or convert the solar energy, the collection system configured to cause solar energy to focus on the target, at least one sensor configured to detect misalignment of the concentrator by determining that some or all of the collected solar energy is offset from the target, and a safety system configured to redirect the energy or interpose a safety structure for shielding other non-target systems from receiving too much solar energy from the collection system.
