How does plasma thruster work?
The thruster works by creating high-current electric arc between the two electrodes. The current running through the cathode back to the power supply induces a magnetic field. The magnetic field and the electric current interact to create a Lorentz force that propels the plasma out of the thruster, producing thrust.
Can plasma generate thrust?
A plasma propulsion engine is a type of electric propulsion that generates thrust from a quasi-neutral plasma. This is in contrast with ion thruster engines, which generate thrust through extracting an ion current from the plasma source, which is then accelerated to high velocities using grids/anodes.
How fast will we travel to Mars?
If you could travel as fast as the New Horizons spacecraft (which is famous for visiting Pluto back in 2015), you could potentially reach Mars in as little as 39 days depending on the alignment of the planets and the 36,000 mph (58,000 kph) speed that New Horizons reached.
Is an electric jet feasible?
It is possible for small aircraft to be powered by electricity. In fact several companies are already developing small electric aircraft and they could come on the market within the next few years. But for the large aircraft we all use more frequently it is unlikely to happen anytime soon.

How does a beam powered propulsion system work?
With beamed propulsion one can leave the power-source stationary on the ground, and directly (or via a heat exchanger) heat propellant on the spacecraft with a maser or a laser beam from a fixed installation. This permits the spacecraft to leave its power-source at home, saving significant amounts of mass, greatly improving performance.
Can a plasma rocket be powered by a laser?
A laser powered plasma rocket is a straightforward solution. A ground based propulsion laser on Earth beams light onto a focusing mirror attached to the spacecraft. This mirror focuses light to an intense hot spot at the target. The target would be a small piece of matter at the center of a magnetic nozzle.
What can be used as a propellant in a plasma engine?
This fact, combined with the absence of hollow cathodes (which are sensitive to all but noble gases) allows the possibility of using this thruster on a a variety of propellants, from argon to carbon dioxide, air mixtures, to astronaut urine. Plasma engines are better suited for interplanetary missions.
