The Texas-based aerospace company Ad Astra's VASIMR engine creates a thicker ion stream by shooting radio waves, rather than electrons, at argon gas. Then, the engine's superconducting magnets fling the ions to generate 50 times as much thrust. In July the company demonstrated the ion-making step, and next month it will fire up the 200-kilowatt machine at full power - almost strong enough that. The Ares 3 mission's duration not only is very similar, but also the book states that four VASIMR engines propelled the ship, Chang said. At some point in the story the Hermes crew start reconfigurating the ship in order to rescue Watney, and they start doing recalculations for a 'slingshot' trajectory that could get Hermes and the Ares 3 crew back to Mars. That is possible thanks to. 4/28/2020 The Variable Specific Impulse Magnetoplasma Rocket (VASIMR) is the newest propulsion engine being used in space exploration.

The Variable Specific Impulse Magnetoplasma Rocket (VASIMR) is a high power, radio frequency-driven magnetoplasma rocket, capable of I s]/thrust modulation at constant power. The physics and engineering of this device have been under study since 1980. The plasma is produced in an integrated plasma injector by a helicon discharge. However, the bulk of the plasma energy is added downstream by ion cyclotron resonance. The system features a magnetic nozzle, which accelerates the plasma particles. planetary missions.1-4 The Variable Specific Impulse Magnetoplasma Rocket (VASIMR®) VX-200 engine is an electric propulsion system capable of processing power densities on the order of 6 MW/m2 with a high specific impulse (2000 s to 5000 s) and an inherent capability to vary the thrust and specific impulse at a constant input power. The potential for long lifetime is due primarily to the radial magnetic confinement of both ions and electron

Diffuse gas is ionized into plasma and contained in a magnetic field, heated by radio frequency energy to a very high temperature, and then allowed to expand out of a magnetic nozzle. This requires a large. But a new engine, called VASIMR (Variable Specific Impulse Magnetoplasma Rocket), will have much more oomph than previous ones. That's because it uses a radio frequency generator, similar to transmitters used to broadcast radio shows, to heat the charged particles, or plasma
So I am using the VASIMR data of approximately 5N of force per 250kw of power draw. As far as I can see, this scales fairly linearly, so 500kw would result in 10N of force. (Might require two engines, I'm not sure how ion drives actually scale up, but that's a separate question) VASIMR technology can be combined with solar power arrays for use in near-Earth, sub-lunar settings. But for Deep Space missions it can be combined with a small nuclear reactor to generate electricity and dramatically increase thrust. Firing a VASIMR engine continuously for a lengthy burn when attached to a nuclear power source would be not only sustainable but also reduce a flight to Mars. The VASIMR® engine has three important features that distinguish it from other plasma propulsion systems: The VASIMR® engine has the ability to more widely vary its exhaust parameters (thrust and specific impulse) in order to optimize mission requirements resulting in the lowest trip time with the highest delivered payload for a given fuel load 2.1.

The VASIMR engine is different, Chang Diaz explained, because of the fuel's electrical charge: When gas gets above 10,000 [kelvins], it changes to plasma - an electrically charged soup of particles. And these particles can be held together by a magnetic field. The magnetic field becomes the canister, and there is no limit to how hot you can make the plasma. We're likely to find.
The VASIMR engine is a concrete development than can make all of this happen. We would like to have efficient fusions rockets, Interstellar Ramjets, beamed energy powered craft, fusion runway craft, and matter antimatter rockets, but we do not yet have such. However, we have a technology which could in theory be powered by fusion, matter/antimatter, beamed energy, and interstellar hydrogen and.
