Self-determined shot geometry for open-configuration portable x-ray computed tomography (CT) includes capturing one or more x-ray shot images into a computing system, and estimating an unknown constellation model and one or more shot geometries. It also includes reconstructing a volume image from the one or more captured shot images and the one or more geometries using computed tomography.

Energy storage radiators are disclosed. The structure of the radiator may be used as a battery to store and release energy, as well as serving to regulate the temperature of that battery and the associated device or vehicle. The structure may be configured to provide mechanical support, an enclosure, an attachment point, or an extension for a vehicle or a device.

Scalable radioisotope power tiles that can provide heat, electrical power, or both, are disclosed. Unlike conventional radioisotope thermoelectric generator (RTG) designs, the scalable radioisotope power tiles do not necessarily seek to minimize the RTG surface area.

A method for self-determination of shot geometry for use in open-configuration portable x-ray computed tomography (CT) includes inputting one or more x-ray shot images into a computing system. The method also include determining, by the computing system, one or more shot geometries from the one or more inputted x-ray shot images.

A propellant management device (PMD) may reduce or prevent liquid propellant from entering a thruster manifold (TM) or gas venting manifold (GVM) while allowing propellant vapor and/or gas to pass through the PMD to allow for thrust or venting.

An expanding battery mandrel includes a cylindrical cell, a cylindrical mandrel having a slit along a length of the cylindrical mandrel, and a plurality of electrolytes wrapped around the cylindrical cell.

A framework for interfacing a blockchain-based ground system with flight software and satellite orbit analysis applications is disclosed. A blockchain application (e.g., a web application) for secure management of satellites has three components—a client, a server, and a private and permissioned-based blockchain network (e.g., a Hyperledger Fabric™ network).

An apparatus for detecting leaks in a battery includes a plurality of cells, each which include a pair of conductive leads bracketing a polymer seal, and a wireless measurement and communication chip (“chip”) configured to perform capacitive measurement, showing a change in capacitance when bridged by ionically conductive species or when a wick is suffused with an electrolyte.

A non-contact angular motion measuring device includes a mirror configured to move or rotate about a pivot axis. The device also includes a curved target, circularly symmetric around an axis normal to the mirror. The device further includes at least one pair of sensors configured to emit fields towards the curved target rather than the mirror.

Embodiments of the present invention include modular solar power cells, arrays, and power management systems for use in satellite systems and constellations.

Methods, systems, and computer program products are described for automatically reducing interference within received signals. A first radio frequency (RF) signal having (i) a desired component and (ii) an interference component with a noise component and a jammed component is received.

Baffled Calotte dome observation and/or communications systems are disclosed. For instance, a visible or infrared telescope and associated sensor systems, a laser, etc., may be enclosed in a Calotte dome with a baffle mounted on the opening and a window and/or filter mounted on top of the baffle.

A free-floating spherical gimbal ("gimbal") that includes a moving portion substantially spherical in shape and partially enclosed within a larger spherical and stationary cavity. The moving portion of the spherical gimbal is maintained in a location without direct mechanical contact with the stationary cavity.

A method of accelerating the reduction of residual stress in a bonded structure is provided. The method can include: providing a bonded structure having at least two substructures, wherein the substructures are bonded together with an adhesive; and submitting the bonded structure to a high-humidity environment having a relative humidity of at least 75%.

Cell-based space systems with nested-ring structures that interlock and can change configuration to support a mission are provided. The cells may self-assemble into a larger structure to carry out a mission. Multiple rotatable rings may be included in a cell, with a payload/control section in the center. The rings may provide power and/or data to trams that move about the rails.

Under one aspect, a method is provided for processing a received signal, the received signal including a desired signal and an interference signal that spectrally overlaps the desired signal. The method can include obtaining an amplitude of the received signal.

Many in the space weather community consider our understanding of the buoyancy of the thermosphere and its effects on the orbits of satellites in Low Earth Orbit (LEO) to be insufficient during short time frames. Disclosed herein is an approach for making on-demand thermosphere buoyancy measurements using a deployable low mass retroreflector with CubeSat-like dimensions.

Under one aspect, a method is provided for processing a received signal, the received signal including a desired signal and an interference signal that spectrally overlaps the desired signal. The method can include obtaining an amplitude of the received signal.

A method for constructing an inflatable environment on top of or beneath a surface of an extraterrestrial object includes spraying Regishell onto an airform or piping the Regishell into a sandwich membrane layer of the airform.

An assembly comprises an exposure chamber configured to receive a structure and identify at least one portion of the structure for further processing. The exposure chamber is further configured to expose the at least one portion of the structure to radiation such that a high cure state and a low residual stress are achieved for the structure.

An apparatus may include a group of distributed-input series-output (DISO) converters, each of which are actively controlled by a common maximum power tracking (MPT) controller.

A mixed-media Ethernet switch (the switch?) is configured to allow a variety of devices to communicate on a given network. The switch includes a plurality of ports. Each of the plurality of ports are configured to connect with, and communicate with, a corresponding traditional medium or non-traditional medium.
