Using Interplanetary Medium as Propellant for Plasma Thruster Propulsion

Abstract: Consuming long-range interplanetary medium with fuel for driving plasma thrust is vital. Methods of capturing the space environment depending on its density and the ship velocity are indispensable issues to extract the space environment as a propellant. This matter of neutral fluxes would use solar radiation to create ionization in a plasma thruster. Extracting propellant at certain ranges look extremely promising where a low thrust device operates continuously to deliver a celestial target close at the speed of light. However, at longer distances, the density of space rapidly diminishes and it may be impossible to maintain at a plasma thruster continuous operation mode but instead might be workable with a pulsed engine. Nonetheless, at still longer-range interstellar missions, the insufficient propellant will require examining other alternatives than a plasma thruster for other candidate propulsion system, possibly either propellantless or a propulsor is driven by electric and/or magnetic fields to satisfy these mission objectives.
