[Paul J Wilbur; United States. National Aeronautics and Space Administration.]. The Plasma and Space Propulsion Laboratory at UCLA is investigating advanced electrospray emitter concepts for high performance, long lifetime, and highly throttlable thrusters.

In particular, the hybrid emitter geometry, which consists of a capillary emitter with a protruding coaxial needle, allows for variable performance depending on the.

Advanced electric propulsion and space plasma contactor research annual report / by: Wilbur, Paul J. Published: () Thin-film photovoltaic solar array parametric assessment / by: Hoffman, David J., Published: (). This plasma is then accelerated out of the thruster by the Lorentz force.

The Lorentz force is a force created by the interaction of a magnetic field and an electric current. As the propellant is consumed, a spring forces the remaining solid propellant forward, providing a constant fuel source.

The Electric Propulsion System. The existence of such an I-V regime is important to achieve low impedance performance without being affected by the space plasma properties for a cathodic plasma contactor. Experimental data on the plasma structure and properties downstream from the ionization stage are presented as functions of the xenon flow rate and the electron emission.

Plasma contactor development for Space Station. The system represents a dual-use technology which is a direct outgrowth of the NASA electric propulsion program and, in particular, the.

Spacecraft employing electric propulsion – e.g., Deep Space 1 (Polk et al., ), SMART (Gonzalez del Amo et al., ), Dawn (Rayman et al., ), and Hayabusa (Kuninaka et al., ) – all use hollow-cathode electron emitters or plasma contactors to actively control the spacecraft conducting structure by providing a low-impedance path.

A plasma propulsion engine is a type of electric propulsion that generates thrust from a quasi-neutral is in contrast to ion thruster engines, which generate thrust through extracting an ion current from the plasma source, which is then accelerated to high velocities using grids/anodes.

These exist in many forms (see electric propulsion). NASA has selected Aerojet Rocketdyne, Inc. of Redmond, Washington, to design and develop an advanced electric propulsion system that will significantly advance the nation's commercial space capabilities, and enable deep space exploration missions, including the robotic portion of NASA’s Asteroid Redirect Mission (ARM) and its Journey to Mars.

An electrically-powered spacecraft propulsion system uses electrical, and possibly also magnetic fields, to change the velocity of a of these kinds of spacecraft propulsion systems work by electrically expelling propellant (reaction mass) at high speed.

Electric thrusters typically use much less propellant than chemical rockets because they have a higher exhaust speed (operate. Preface This book is the second volume of our introductory text on Space Plasma Physics.

American Institute of Aeronautics and Astronautics Sunrise Valley Drive, Suite Reston, VA This is the goal of NASA’s Solar Electric Propulsion project, of which the PPU development is part.

Hall-effect drives are different from the so-called Em drive, which supposedly works (it’s still not clear that it works) by using an electromagnetic field to produce thrust despite the absence of any reaction. Plasma-based propulsion is becoming the baseline solution for satellite stationing and attitude/orbit control.

This electric propulsion technology, also called Hall effect or stationary plasma thrusters, offers a significant weight reduction compared with traditional chemical propulsion systems. In this type of system, a stream of electrons bombards a fuel (such as xenon gas).
