A configurable spacecraft attachment and deployment system and a method of constructing a configurable spacecraft attachment and deployment system are provided herein. In one embodiment, the configurable spacecraft attachment and deployment system includes: (1) a connecting structure configured to secure at least one spacecraft to a launch interface, (2) an actuating assembly configured to constrain the spacecraft to the connecting structure before deployment thereof and release the spacecraft from the connecting structure when deployed, and (3) a deploying mechanism coupled to the connecting structure and configured to eject the spacecraft from the attaching structure, wherein the connecting structure, the actuating assembly, and the deploying mechanism are modular components and the connecting structure and deploying mechanism are selected to form the system based on parameters of the spacecraft.

In at least one aspect, a small satellite includes a cylindrical body, a predetermined payload volume, a payload adapter ring mechanical interface for interchangeably mechanically coupling to a launch vehicle payload adapter ring, an electrical interface specifying a set of electrical specifications for interchangeably electrically coupling to the launch vehicle payload adapter ring, a specified center of gravity location and specified frequency response, where the predetermined payload volume, payload adapter ring mechanical interface, electrical interface, specified center of gravity location, and frequency response range allow the small satellite to be interchanged with other small satellites when coupling to the launch vehicle.

A nanosatellite with an illumination element, and an arrangement of nanosatellites in low earth orbit (LEO) arranged to controllably apply their illumination to be visible on the ground. The nanosatellites may be coordinated to provide illumination events visible on the ground at particular locations and particular times. Each nanosatellite has an illumination element that provides a sustained external illumination event being of at least momentary duration and to be visible from the ground. The event forms at least part of a display for viewing from the ground.

A satellite includes a housing, a circuit board containing circuitry, a battery electrically connected to the circuit board, a tank, an expandable balloon disposed in the tank, a heater, a valve providing liquid communication between the tank and the heater when in an open position and providing no liquid communication between the tank and the heater when in a closed position, and a nozzle having an orifice in liquid communication with the heater. Operating the satellite includes partially filling the expandable balloon with a gas, loading liquid fuel into the tank, launching the satellite into space, opening the valve to cause the liquid fuel from the tank to pass into the heater under pressure provided by the gas in the expandable balloon, activating the heater to heat and vaporize the liquid fuel into a fuel vapor, and expelling the fuel vaper out of the nozzle.

A satellite assembly is disclosed, including a satellite and a shroud. The satellite is stowed in a launch vehicle and the shroud includes a frame supporting a flexible thermal blanket enclosing the satellite.

A satellite apparatus is disclosed, including a housing having first and second opposing walls, and a support structure inside the housing spanning the first and second walls. The support structure is structurally connected to the housing only at the first and second walls, and an end portion of the support structure is configured for connection to a launch vehicle by a separation system.

A strut-and-node truss design that is applicable to space frame structure designs can be assembled with using robotic (semi-autonomous and/or fully autonomous) or telerobotic assembly/joining. The assembly system can include a storage module that includes the components for assembly and an assembly module that can retrieve and assembly the components. The resulting truss structure can be connected to an antenna (e.g., carried by the storage module) for deployment. The assembly module can be operated repeatedly in conjunction with additional resupply systems that provide additional components for assembly.

A satellite dispenser includes a central tubular structure. The satellite dispenser also includes a plurality of satellites arranged around the central tubular structure. The satellite dispenser further includes a plurality of shear connectors coupling the central tubular structure and the plurality of satellites arranged together in shear continuity.

A satellite system can include one or more satellites that orbit the Earth. The one or more satellites may have satellite buses that support antenna arrays. The antenna arrays may include space fed arrays. Each space fed array may have an antenna feed array and an inner array that is coupled to a direct radiating array. The direct radiating array may operate in the same satellite band as the space fed array, or upconversion and downconversion circuitry may be used to communicatively couple a direct radiating array that operates in a different satellite band to the space fed array. The satellites may have peripheral walls with corner fittings that can be selected to provide the satellite bus with particular leg strengths. This can reduce overall mass of the satellites in a payload fairing while accommodating different types of antenna arrays.

A satellite system may have a constellation of communications satellites in orbits such as highly inclined eccentric geosynchronous orbits and low earth orbits. To place satellites in inclined eccentric geosynchronous orbits, a series of launch vehicles may be launched. Each launch vehicle may be used to place a set of satellites, such as a set of three satellites, into a common orbital plane with distinct longitude of ascending node values. To place satellites in low earth orbits, a series of launch vehicles may be launched, each of which releases satellites in sequence from a stack of satellites into a common orbital plane. After desired separations have been produced between the released satellites, circularization procedures may be performed using the propulsion systems of the satellites to place the satellites into final orbit.
