Space vehicles are provided, each including a body and a solar panel array system. The body has a longitudinal axis and a plurality of body portions. Adjacent body portions are hinged to one another about a respective body hinge axis to enable the body portions to be selectively pivoted about the respective body hinge axes with respect to one another from an undeployed configuration to a deployed configuration. In the undeployed configuration the body has a first length dimension along a reference axis, and in the deployed configuration the body has a second length dimension along the reference axis. The second length dimension is greater than first length dimension. The solar panel system includes at least two panel sets. Each panel set has at least one solar panel, each panel set being movably mounted to one of the body portions and being selectively deployable from a stowed configuration to an extended configuration. In the stowed configuration the at least one panel of each respective panel set is in circumferentially overlapping relationship with an outside of the body, and in the extended configuration, the panels are projecting away from the respective the body portion. Methods for deploying a space vehicle are also provided.

The present invention relates to articulating spacecraft chassis and methods of making and using same. The present invention relates to spacecraft chassis and methods of making and using same. Such spacecraft chassis have a dynamic movement capability that allows the spacecraft to alter its structure while still maintaining industry volumetric launch standards. This capability increases opens up a wide range of achievable volumetric states and increases the ability to meet mission requirements by introducing a new tunable parameter. In addition, the judicious selection of certain dynamic movement parameters can result increased payload capabilities and improved maneuverability.

A landing device for a low gravity lander having a main body. The landing device comprises a number of leg-like rods attached to the main body, wherein, in a deployment position of the rods, each of the number of rods is inclined with regard to a plane of a first side surface of the main body such that the rods substantially extend in a direction of movement of the low gravity lander. Furthermore, the number of rods is made such that they bend or buckle under forces within a predetermined range by an impact due to a landing on a landing surface, thereby absorbing an impact momentum.

Latching or locking deployment hinges are provided that include a latch mechanism, a spring-loaded tensioning device, and a trigger mechanism. The trigger mechanism and the spring-loaded tensioning device are configured to transfer the compressed spring load in the spring-loaded tensioning device to the latch mechanism once the hinge has closed sufficiently far enough to latch together, thus inducing a pre-load through the latch mechanism that eliminates gapping in the hinge interface. The hinges may be sprung or actuated using a powered drive mechanism.

A panel array and associated deployment system may include a first cable extending along a first row of panels and coupled to each panel of the first row of panels. The array and system may further include a second cable extending along a second row of panels and coupled to each panel of the second row of panels. The array and system may also include a first column of panels comprising a panel from the first row of panels and a panel from the second row of panels. The system may further include a spool positioned adjacent the first column of panels. The spool may be coupled to at least one of the first cable and the second cable and configured to apply tension to the first cable and/or the second cable.

Embodiments generally relate to small satellites. Example small satellites may include a satellite body having a rectangular tile shape, with a substantially flat front side having a length and width and being separated from a substantially parallel back side by a depth, wherein the depth is equal to or less than a third of the length and the width. A patch antenna array may be positioned on the front side and/or a large patch antenna may be positioned centrally on the front side. A solar panel may be positioned on or coupled to the back side.

A reusable device for holding and releasing a bar. The device includes a tightening component, a hold and release component, and at least one loosening component. The hold and release component includes a plurality of segments, each segment includes a first bearing surface configured to bear on part of the bar, when the plurality of segments is in a holding configuration under the effect of a tightening pressure generated by the tightening component. The plurality of segments includes a second bearing surface configured to bear on one end of the at least one loosening component. The at least one loosening component is made from a first single-acting shape memory material. Each end of the at least one loosening component exerting a loosening pressure compensating for the tightening pressure, so as to place the hold and release component in a configuration in which the part of the arm is released.

A deformable support apparatus includes a deformable body configured to transition between at least an extended state and a contracted state where a stiffness of the deformable body in the extended state is greater than a corresponding stiffness of the deformable body in the contracted state. The deformable body includes a first member and a second member coupled to and in opposition to the first member, and arranged about a longitudinal axis. In the extended state, the first member has at least a first curved portion and the second member has at least a second curved portion. The at least a first curved portion is a positive curved portion with respect to the longitudinal axis and the at least a second curved portion is a negative curved portion with respect to the longitudinal axis.

An exemplary embodiment of the present invention provides a deployable solar panel mounted on a movable body configured to be movable, the deployable solar panel including: a solar panel mounted on an outer portion of the movable body and configured to convert light energy into electrical energy; and a yoke having a reinforcing part stacked on at least one surface of a base to connect the movable body and the solar panel and configured to attenuate vibration transmitted to the solar panel.

Exemplary embodiments are described herein for compactable antennas. Exemplary compactable antennas include a support structure and a reflector surface. The support structure may directly or indirectly define the reflector shape. Exemplary embodiments comprise deployable support structures to permit the compactable antenna to have a smaller volume stowed configuration and a larger volume deployed configuration.
