  • Patent number: 9022323
    Abstract: For capturing satellites and other orbital objects, one or more independent capturing units are releasably arranged on a spacecraft serving as a steerable carrier vehicle. Each capturing unit has a propellant charge and at least one braking thrust nozzle of its own, and a closeable capture net releasably connected to the capturing unit via a tether line. The net is deployed from the capturing unit to capture the orbital object. Position or attitude control engines of the carrier vehicle are operated for orienting the combination including the capturing unit and the orbital object captured in the net. The capturing unit is then released from the carrier vehicle, and applies a braking thrust to the captured object so as to deorbit the captured object together with the capturing unit.

  • Publication number: 20150115106
    Abstract: A tethered spacecraft has a first endmass and a second endmass with a telescoping stacer spring and a tether arranged between the endmasses. The spring is coiled around a center rod and initially contained within a housing, the spring being biased to push the first endmass away from the second endmass. The spring housing is affixed to the first endmass, a first end of the spring being affixed to the spring housing, and tether are affixed to spring at one end and to the second endmass at the other end. A pretensioned loop holds the endmasses abuttingly together, and a burnwire release mechanism cuts the loop to deploy the spring. Upon deployment, the spring extends to its full length to form a cylindrical boom, and the endmasses continue to move outward along the spring centerline until stopped by the tether.

  • Publication number: 20130233974
    Abstract: The invention relates to the energy provision of space transport systems and to the organization of a load flow between spacecraft in planetary orbits. The method comprises a spacecraft tank trapping and accelerating atmospheric air and loads located in the trajectory of movement thereof. The loads are transported beforehand to said trajectory by corresponding spacecraft, including suborbital spacecraft, and are then transferred to other spacecraft. Velocity losses of the spacecraft tank due to the trapping and accelerating of atmospheric air, loads and to aerodynamic drag are compensated for by a propulsion unit. The propulsion unit may use reactive engines—with consumption of part of the incoming load—or electrodynamic cable systems. Operation of the propulsion unit of the spacecraft tank is ensured by a supply of load energy carriers using atmospheric gases.

    Abstract: In some embodiments of the invention, methods and devices are provided that perturb a trajectory of a space-orbital object. For example, a spacecraft may be sent to a location near a space-orbital object orbiting the Earth. A net may be released from the spacecraft in a manner (e.g., with a given alignment, direction and velocity) that results in the net contacting and/or entangling with the object. This contact or entanglement may alter a velocity of the space-orbital object and thereby may alter its orbital path. In some instances, the net's velocity is sufficient to experience increase drag by the Earth's atmosphere, relative to the drag it would have otherwise experienced if the net did not contact the object.

  • Patent number: 7413147
    Abstract: The invention is a system and method for propellantless, ultrahigh precision satellite formation flying based on ultrahigh precision intracavity laser thrusters and tethers with an intersatellite distance accuracy of nanometers at maximum estimated distances of tens of kilometers. The repelling force of the intracavity laser thruster and the attracting force of tether tension between satellites form the basic forces to stabilize matrix structures of satellites. Users of the present invention can also use the laser thruster for ultrahigh precision laser interferometric metrology, resulting in simplification and payload weight reduction in integrating the thruster system and the metrology system.

  • Publication number: 20080185481
    Abstract: Methods and systems for providing space tethers for limiting the dynamic response of structures are disclosed. In one embodiment, a method for limiting the dynamic response of a structure having a base member and a substructure projecting outwardly from the base member includes coupling a first end of an elongated flexible tether to the substructure at a first location spaced apart from the base member; and coupling a second end of the elongated flexible tether to the base member at a second location spaced apart from the substructure, the tether being configured to be in a non-taut configuration when the substructure moves within a design volume with respect to the base member, the tether being further configured to be in a taut position when the substructure displaces to a limit of the design volume.

  • Patent number: 7207525
    Abstract: A remotely controlled apparatus for grasping an object such as a satellite in space includes a free-flying grasper unit connected by a selectively extendable cable to an orbital platform. The orbital platform and the grasper unit are preferably each independently propelled by respective propulsion systems including multi-axis maneuvering nozzles respectively provided on the orbital platform and on the grasper unit. The grasper unit preferably includes a grasper unit body and a grasper-arm mechanism having a controllable grasping claw articulately mounted on the end of a controllable telescoping arm that extends from the grasper unit body. The grasper unit preferably further includes a camera and a distance measuring sensor to provide visual and distance feedback data for assisting the remotely controlled maneuvering of the grasper unit and actuation of the grasper-arm mechanism.

  • Patent number: 7178763
    Abstract: Mechanism for passively deploying expendable space tethers on orbit, by means of an initial separation impulse only, provided by a simple spring system that is part of the mechanism itself. The passive deployment of the space tether and a tethered end-mass is provided by the particular mechanism devised, having very low deployment friction and resistance. Tether deployment brake towards the final part of deployment is produced by a daisy-like brake, stored within the winding of the fixed tether spool so that it is automatically deployed (opened) and starts its deployment braking or resistance function from a planned point of the tether deployment in space.

  • Patent number: 7168660
    Abstract: Capture devices are mounted on a space platform such as a spacecraft or utility satellite. Each capture device includes a folded capture net stored in a housing, guide weights connected to the net and received in spring-loaded ejection tubes oriented at an acute angle relative to the axis of the housing around the perimeter thereof, and a spring-loaded releasable cover that is connected to the net, covers the net in the housing, and holds the weights in the ejection tubes. When the cover is released, it is spring-ejected from the housing while pulling out and unfolding the net, and the weights are spring-ejected out of the ejection tubes while spreading out the net. After the net wraps around a free-flying target object in space, net closure mechanisms reel-in a net pursing line to close the net, which is connected to the space platform by a tether line on a winch.

  • Patent number: 7118074
    Abstract: A tether system for providing thrust to or power subsystems of an artificial satellite in a low earth orbit. The tether has three main sections, an insulated section connected to the satellite, a conducting section connected to the insulating section for drawing in and releasing electrons from the space plasma and a non-conducting section for providing a tension to the other sections of the tether. An oxygen resistant coating is applied to the bare wire of the conducting section as well as the insulated wires of the insulated section that prevents breakdown during tether operations in the space plasma. The insulated and bare wire sections also surround a high tensile flexible polymer core to prevent any debris from breaking the tether during use.
