The Variable Specific Impulse Magnetoplasma Rocket (VASIMR) is an electro-magnetic thruster for spacecraft propulsion. It uses radio waves to ionize a propellant and magnetic fields to accelerate the resulting plasma to generate thrust.

Current rockets… Only works on vacuum..
“VASIMR is not suitable to launch payloads from the surface of the Earth due to its low thrust to weight ratio and its need of a vacuum to operate” (Wiki)

Sweet we have Ion engines.

Ionized Plasma, but yes we can build TIE fighters now. Dogfights will take days or weeks, and the ships will be the size of buses.

The Orion Project was way cooler!

George Dyson’s book ‘Project Orion’ is a great read.

Very cool, and unlike Project Orion, might actually occur in this political climate (nukes in space? that won’t freak out other nations). Neat technology, but the energy usage makes it difficult to implement.
