3. What Is An Ion Thruster
Form of electric propulsion that creates thrust by accelerating ions
Electrostatic – use Coulomb Force
Electromagnetic – use Lorentz Force
Currently Only Practical in Space

4. What Is An Ion Thruster Low Thrust, High Efficiency 0.5 N of Thrust
200,000 mph top speed
18,000 mph in Space Shuttle
Low impulse = 90% efficiency
35% in Space Shuttle
