162. Variable-Specific-Impulse Magnetoplasma Rocket of one of the propulsion systems being considered by NASA for a manned Mars mission....... http://www.nasatech.com/Briefs/Sep01/MSC23041.html

Variable-Specific-Impulse Magnetoplasma Rocket Discuss this and other technologies with colleagues at the Reader Forum This rocket is expected to enable long-term human exploration of outer space. Lyndon B. Johnson Space Center, Houston, Texas I sp ) places the VASIMR far ahead of anything available today. Inasmuch as this rocket can utilize hydrogen as its propellant, it can be operated at relatively low cost. Because the VASIMR uses plasma to produce thrust, it is related to several previously developed thrusters; namely, the ion engine, the stationary plasma thruster (SPT) (also known as the Hall thruster), and the magnetoplasmadynamic (MPD) thruster [also known as the Lorentz-force accelerator (LFA)]. However, the VASIMR differs considerably from these other thrusters in that it lacks electrodes (a lack that enables the VASIMR to operate at much greater power densities) and has an inherent capability to achieve high and variable I sp . Both the ion engine and the SPT are electrostatic in nature and can only accelerate ions present in plasmas by means of either (1) externally applied electric fields (i.e., applied by an external grid as on an ion engine) or (2) axial charge nonuniformity as in the SPT. These ion-acceleration features, in turn, result in accelerated exhaust beams that must be neutralized by electron sources strategically located at the outlets before the exhaust streams leave the engines. In the LFA, acceleration is not electrostatic but electromagnetic. A radial electric current flowing from a central cathode interacts with a self-generated azimuthal magnetic field to produce acceleration. Although LFAs can operate at power levels higher than those of either the ion engine or the SPT and do not require charge neutralization, their performances are still limited by the erosion of their electrodes.

Advanced Propulsion Space Settlement relevance Even though modern chemical rockets have sent us to the Moon, to build large space settlements we will need something more. Today, the high cost of launching into space limits the number of people who go there. Advanced propulsion, however, offers a chance to dramatically lower launch costs. Futhermore, many of the ideas being proposed would allow us to move around the solar system much quicker than we do today. Instead of months to Mars, it would be weeks. Years to Jupiter and Saturn would be months. And centuries to the stars would become years.

169. Electric Propulsion Electric propulsion is most broadly defined as the acceleration of propellants by electrical Electric propulsion technology is steadily improving as our http://www-leland.stanford.edu/group/pdl/EP/EP.html

SPDL Electric Propulsion Activities Overview Electric propulsion is most broadly defined as the acceleration of propellants by electrical heating, electric body forces, and/or magnetic body forces. This leads to a natural division of the three forms of electric propulsion. In Electro-Thermal thrusters, the propellant gas is electrically heated and expanded through a nozzle. Common examples include resistojets and arcjets. In Electro-Static thrusters, the propellant is ionized and the resulting ions are accelerated through an electric potential. Common examples include Hall effect and Kaufmann type thrusters. Electro-Magnetic thrusters utilize electric and magnetic body forces to accelerate ions. The most common type of electromagnetic thruster is the magnetoplasmadynamic thruster, or MPD. Research Statement Electric propulsion technology is steadily improving as our understanding of the physics governing thruster operation increases. Efforts that combine both experimental and theoretical studies of the plasmas within electric propulsion thrusters are necessary in order to build reliable models of performance that can be then used as design tools for improved next generation thrusters. Areas of Active Research Arcjet Thrusters Due to their relatively high specific impulse (500-1,200 sec.) and moderate thrust levels, electro-thermal arcjet thrusters are playing a growing role in satellite propulsion. Existing and planned applications include arcjet thrusters for station-keeping and on-orbit maneuvering. Low power hydrazine arcjets are now in use on the TelStar IV class of communication satellites and the first space test of a high power arcjet for use in orbit raising operations will be launched in 1997 under the Air Force

The laboratory began investigating HEV technologies more than a decade ago. In the past few years several commercial HEV models, which are powered simultaneously by batteries and fuel, have taken their place in the mainstream automobile market. More recently, HEV drivetrains have been used successfully in heavy-duty trucks, buses, and military vehicles.
