The opposite difference is that the only cathode is replaced by multiple, smaller cathode rods packed right into a hollow cathode tube. In the middle is a spike that is wound to provide a radial magnetic discipline between it and
Vapor devices the surrounding tube.
The gadget has a roughly constant magnetic discipline in the source tube (supplied by solenoids within the prototype), but the magnetic subject diverges and quickly decreases in magnitude away from the supply region and may be considered a type of magnetic nozzle. This separation of the ionization and acceleration phases allows throttling of propellant circulation, which then changes the thrust magnitude and specific impulse values. The antenna then excites a helicon wave in the plasma, which additional heats it.
The LiLFA thruster builds on the MPD thruster. Under a research grant from the NASA Lewis Research Center during the 1980s and nineties, Martin C. Hawley and Jes Asmussen led a group of engineers in developing a microwave electrothermal thruster (MET). Using topographic information, NASA groups deduced that crustal depression associated with a distinguished mountain ridge on the main hemisphere is finest defined if there was a worldwide subsurface liquid ocean like that of Enceladus.
This venture is led by former NASA astronaut Franklin Chang-Díaz (CRC-USA). The subsurface ocean could have resulted from a 2:Three orbital resonance between Dione and Tethys early within the Solar System's historical past that led to orbital eccentricity and tidal heating of Tethys's inside. Its orbital eccentricity is negligible, and its orbital inclination is about 1°. Tethys is locked in an inclination resonance with Mimas; nonetheless, as a result of low gravity of the respective our bodies, this interplay does not cause any noticeable orbital eccentricity or tidal heating.
This resonance maintains Enceladus's orbital eccentricity (0.0047), providing a supply of heat for Enceladus's in depth geological exercise, which shows up most dramatically in its cryovolcanic geyser-like jets. A small part of the surface is coated by smooth plains that could be cryovolcanic in origin. Its origin may be associated to a deposition of bright ice particles from the E-ring onto the leading hemispheres and

This coloration and darkening of the Tethyan floor is typical for Saturnian center-sized satellites. The fashionable names of all seven satellites of Saturn come from John Herschel (son of William Herschel, discoverer of Mimas and Enceladus). Once Mimas and
