Now, the future has arrived. This important new book explains the fundamentals of electric propulsion for spacecraft and describes in detail the physics and characteristics of the two major electric thrusters in use today, ion and Hall thrusters. The authors provide an introduction to plasma physics in order to allow readers to understand the models and derivations used in determining electric thruster performance. They then go on to present detailed explanations of: Thruster 410 0$aJPL space science and technology series ;$v1. 606 $aIon rockets 615 0$aIon rockets. 676 $a629.47/55 700 $aGoebel$b Dan M.$f1954-$0870086 701 $aKatz$b Ira$f1945-$0870087 801 0$bMiAaPQ 801 1$bMiAaPQ 801 2$bMiAaPQ 906 $aBOOK 912 $a9910144427803321 996 $aFundamentals of electric propulsion$91942507 997 $aUNINA
