Electric rockets

High efficiency, low thrust, long duration.

Electric propulsion is not a launch replacement from Earth, but it is powerful for in-space station-keeping, orbit raising, and deep-space missions.

Hall Thrusters

Ionize xenon or krypton and accelerate ions with electric and magnetic fields.

Gridded Ion

Very high specific impulse with low thrust, suited to long-duration science and commercial spacecraft.

Nuclear Electric

A reactor can provide electric power for efficient low-thrust propulsion over long periods.

Reality Check

Electric propulsion can reach high total velocity over time, but thrust is too low for launch from Earth. Chemical rockets remain necessary for liftoff.
