NRL's Magnetically Attracted Fluid System (Code 8230). The system allows fluid transfer in conditions where the host and target systems are moving independent of each other at unknown and uncontrolled relative rates., Schematic of NRL’s Magnetically Attracted Fluid Transfer System (NRL Code 8230). System was initially designed and prototyped to transfer fuel through a robotic arm from a host refueling ship to a target fuel tank on an unmanned surface vehicle, without the need for direct, Diagram of NRL’s Magnetically Attracted Fluid Transfer System (NRL Code 8230). The system reduces or eliminates the need for human intervention in the process. Magnetically Attracted Fluid Transfer System

NRL in partnership with the Defense Advanced Research Projects Agency (DARPA) have developed a new system where a refueling vehicle can be operated autonomously or remotely to fuel a vehicle with a magnetically coupled rapid-breakaway fuel transfer system. The system provides a self-aligning magnetic connection between the host system and a target system. The magnetic connection includes a transferrable puck that the host system manually or autonomously attaches to a target vehicle’s fuel receptacle. Enhancing the system with a controllable electromagnet, it can directly control when the puck is transferred or if a connection should be maintained during refueling. The magnetic connection differential allows the puck to connect to the target system, and in the case of a jolt to the system, the magnetic connection will be lost to the host system while the puck remains connected with the target.

  • New “step” architecture for space solar module (patent pending) better radiates heat
  • Module four-times more efficient at converting sunlight to microwave energy than closest competitor
  • Assembled in satellite array, modules could beam power to on-Earth receiver, providing sustainable, base-load power for a city or military missions
Low Earth orbit is the region of space within 2,000 kilometers of the Earth's surface. It is the most concentrated area for orbital debris., Orbital debris mitigation Mitigation Concept of Low Earth Orbit

Physicist and Engineers at the U.S. Naval Research Laboratory Plasma Physics Division and Naval Center for Space Technology have researched a technique to 'sweep' Low Earth Orbit (LEO) debris from space using an Active Debris Removal (ADR) system of deployed micron-scale dust.
