Electric Propulsion
This type of Ion Thruster does not have corrosion as a drawback.
What is a Hall Thruster?
These are the two types of nuclear propulsion methods that satellites use.
Thermal and Electric
This type of maneuver allowed the Voyager spacecrafts to propel itself farther distances in our solar system.
What is a gravity assist?
A type of gas process that utilizes high pressure to expand its propellant for thrust.
Cold gas
The charge on the propellant atoms as they enter the discharge chamber.
What is neutral?
This is the isotope that is used during a nuclear reaction to create heat.
Uranium-238
The Solar Electric propulsion system aboard the Psyche spacecraft is this many times more effective than traditional chemical thrusters.
What is 15 times more effective?
A type of gas process that utilizes combustion to expand its burnt propellant for thrust.
Hot gas
They cause the electrons to stay in the discharge chamber for longer so there can be more collisions with propellant ions.
What are magnets/magnet?
This is what's used to convert the heat generated by nuclear fission into electricity for a nuclear-electric propulsion system
Thermionic converter/Thermionic reactor
The difference between specific impulse and impulse bits.
Specific - ratio of thrust to weight flow rate
Bits - Δp required for accurate and precise orbital control
Type of propulsion device that solid propellants are widely used for, and at least one reason why.
Boosters. Solid propellants are cheaper & easier to store (low degradation over time)
