Disclosed are a method of flying on the moon and a device for flying using the method. A medium on a surface of a moon and a medium accelerating module are used in the flying method. The medium is transferred into the medium accelerating module, accelerated by the medium accelerating module, and ejected out of the medium accelerating module by using a power supply. A counterforce is generated in accordance with the momentum conservation, and the counterforce overcomes the lunar gravity and drives a load to take off. The method is suitable for the environment of the moon where flight by means of atmospheric buoyancy is impossible due to the shortage of atmosphere.

Systems and methods are disclosed for mining lunar and Martian polar permafrost to extract gas propellants. The method can comprise identifying a plurality of near-polar landing sites in craters in which the surface comprises permafrost in perpetual darkness, wherein such landing sites have perpetual sunlight available at altitudes of about 100 to 200 m. A mining outpost can be established in at least one of the sites and a high altitude solar array deployed at the landing site using a lightweight mast tall enough to generate near continuous power for the outpost. Systems and apparatus are disclosed for mining the permafrost at the landing sites using radiant gas dynamic mining procedures. The systems can comprise a rover vehicle with an integrated large area dome for cryotrapping gases released from the surface and multi-wavelength radiant heating systems to provide adjustable heating as a function of depth.

Described herein are apparatuses and methods for use therewith that can be used to remove dust and other types of particulates from a solar array of a spacecraft, a lander, a rover, or the like. Such an apparatus can include a main body and a solar array extending from the main body. One or more piezoelectric devices is/are attached to the solar array. The piezoelectric device(s), when activated, is/are configured to vibrate at least a portion of the solar array to thereby loosen particulates adhered thereto. The apparatus also includes one or more linear actuators that when actuated is/are configured to at least one of bump against, push on, or pull on at least a portion of the solar array to thereby jettison from the solar array at least some of the particulates that were loosened by the one or more piezoelectric devices.

An assembly for providing an active seismic source includes a motor and a drive shaft coupled to the motor. A crank is coupled to the drive shaft. The motor is configured to impart rotation of the crank in a first rotational direction. A one-way bearing permits rotation of the crank relative to the drive shaft in the first rotational direction and inhibits rotation of the crank relative to the drive shaft in an opposed second rotational direction. The assembly also includes a strike plate, a track, and a hammer that is movable along the track along an axis that extends toward and away from the strike plate. The hammer contacts the strike plate. A biasing element biases the hammer toward the strike plate. A linkage arm couples the hammer to the crank and translates rotational movement of the crank to linear movement of the hammer.

Described herein is a method of constructing a landing pad using a rocket engine while in-flight. Among other benefits, this method can reduce ejecta that otherwise would occur during landing on an unimproved surface. While a spacecraft is hovering over an unimproved surface, the spacecraft can inject particles into its rocket engine, after which the particles absorb heat from the engine and are projected at ballistic speeds toward the unimproved surface to create a landing pad. After constructing the landing pad and waiting for the landing pad to cool, the spacecraft can land on the landing pad. Also described herein are landing pads created from such particles as they impact the surface in a disc splat mode into the unimproved surface.

A reconnaissance rover configured for multiple agile and autonomous landings over a small body or moon. The reconnaissance rover comprises a detection unit, a processing unit, a control unit and a drive unit. The detection unit is configured to detect at least an environment in front of the reconnaissance rover, in the direction of a trajectory of the reconnaissance rover over a surface of the small body or moon. The detection unit is further configured to provide environmental data based on the detected environment. The processing unit is configured to update the trajectory based upon the provided environmental data. The control unit interacts with the drive unit to move the reconnaissance rover according to the updated trajectory.

An energy absorption system, for absorbing an impact energy imparted to a subject upon landing on a surface, includes a mass containment vessel fixed to the subject and a plurality of electromagnets disposed at fixed positions relative to the mass containment vessel. The mass containment vessel may contain one or more mass elements movably disposed therein. A controller may be configured to charge one or more of the electromagnets upon an impact of the subject with the surface to move the mass element(s) toward the surface by electromagnetic force. Alternatively, the energy absorption system may include a pulley system operable to mechanically move one or more mass elements along an axis, a multi-axis joint connecting the pulley system to the subject, and a controller configured to operate the pulley system upon an impact of the subject with the surface to mechanically move the mass element(s) toward the surface.
