Thrusters for propulsion generally require nozzles but is this necessary in the vaccum of space?

Space junk is a major problem for space travel. We use an energetic particle beam to manoeuvre a satellite close to junk then blast it with the particle beam to deorbit the junk

Low Earth Orbit satellites such as CubeSats can have their lifetime boosted by using our unique plasma thrusters to insert them into higher orbits. 

Active plasma thrusters are needed for in orbit manouvers and for arranging constellations of satellites. 

We employ Particle in Cell simulations that are inexpensive true computer experiments to complement the use of costly industrial microchip plasma systems.

High power ion beams can be used to replace lasers as sources for evaporated coating material. Work with industry to discover the physics.

There is no lunar GPS so how will satellite orbits be determined for safety and efficiency in designing missions.

When plasmas are decoupled from their source of power, much can be learned about non-local effects of energy transport.

Experimental work on expanding plasmas is greatly aided by computer simulation using plasma fluid codes.
