6 kW Hall thruster in operation at the NASA Jet Propulsion Laboratory. In spacecraft propulsion, a Hall-effect thruster (HET) is a type of ion thruster in which the propellant is accelerated by an electric field. Hall-effect thrusters (based on the discovery by Edwin Hall) are sometimes referred to as Hall thrusters or Hall-current thrusters.
AEPS is based on the 12.5 kW development model thruster called 'Hall Effect Rocket with Magnetic Shielding' (HERMeS). The AEPS solar electric engine makes use of the Hall-effect thruster in which the propellant is ionized and accelerated by an electric field to produce thrust. To generate 12.5 kW at the thruster actually takes a total of 13.3 ...
PPS-1350 is a Hall-effect thruster, a kind of ion propulsion system for spacecraft. It was used in the SMART-1 mission to the moon and one geostationary satellites: Inmarsat-4A F4. [1] [2] It creates a stream of electrically charged xenon ions accelerated by an electric field and confined by a magnetic field. [3]
SPT-140 is a solar-powered Hall-effect ion thruster, part of the SPT-family of thrusters. SPT stands for Stationary Plasma Thruster. [1] [2] Like other members of the SPT series, it creates a stream of electrically charged xenon ions accelerated by an electric field and confined by a magnetic field. [3]
SPT-series thrusters. Upper-left one is SPT-100. SPT-100 is a Hall-effect ion thruster, part of the SPT-family of thrusters.SPT stands for Stationary Plasma Thruster.It creates a stream of electrically charged xenon ions accelerated by an electric field and confined by a magnetic field.
An MPD thruster was tested on board the Japanese Space Flyer Unit as part of EPEX (Electric Propulsion Experiment) that was launched March 18, 1995 and retrieved by space shuttle mission STS-72 January 20, 1996. To date, it is the only operational MPD thruster to have flown in space as a propulsion system.
A former Tennessee teacher who got pregnant after raping a 12-year-old boy pleaded guilty and has been sentenced to 25 years in prison with no parole. On Dec. 20, Alissa McCommon, 39, of Covington ...
Busek has also developed Hall thrusters that operate on iodine, [10] [11] bismuth, [12] [13] carbon dioxide, [14] magnesium, [15] zinc, [16] and other substances. An iodine fueled 200 W Busek Hall thruster will fly on NASA's iSat (Iodine Satellite) mission. Busek is also preparing a 600 Watt iodine Hall thruster system for future Discovery ...
