NASA Plans Test of New Plasma Drive

Sallust writes "Flightglobal has an interesting article about the testing of a new electrically powered plasma engine called the Vasimir. It's being developed by former astronaut Franklin Chang-Diaz and promises to greatly reduce the time and fuel required for interplanetary journeys. According to the article: 'The Vasimir involves the injection of a gas such as hydrogen into an engine that turns it into a plasma. That plasma is then energised further using radio signals as it flows through the engine, a process controlled by electromagnetic waves from superconducting magnets. Accelerated and heated through this process the plasma is focused and directed as exhaust by a magnetic nozzle. Vasimir is many times more efficient than conventional chemical rockets and far less fuel is needed.' The developers are finalising an agreement with NASA to fit a scaled-down version of the engine to the ISS to conduct operational tests. There is also a concept video on YouTube suggesting a journey time for a manned craft to Mars on the order of 60-70 days."

      I'm sorry but, in Soviet Russia you will propel the plasma engine.

    everything's working towards the big flash. you call this 'weather'? the difference between the 'laws'/perception of man'kind' & the processes of the creators, will become crystal clear to those whose conscience/spirit have not been damaged, or completely taken, by man-made illusions. fear is the primary weapon of unprecedented evile. that, along with deception & coercion, helps most of us remain (unwittingly?) dependent on its' greed/fear/ego based hired goons' agenda. Most of yOUR dwindling resources are being squandered on the 'war', & continuation of the billionerrors stock markup FraUD/pyramid scheme. nobody ever mentions the real long term costs of those debacles in both life & the notion of prosperity, not to mention the abuse of the consciences of those of us who still have one. see you on the other side of it. the lights are coming up all over now. conspiracy theorists are being vindicated. some might choose a tin umbrella to go with their hats. the fairytail is winding down now. let your conscience be yOUR guide. you can be more helpful than you might have imagined. there are still some choices. if they do not suit you, consider the likely results of continuing to follow the corepirate nazi hypenosys story LIEn, whereas anything of relevance is replaced almost instantly with pr ?firm? scriptdead mindphuking propaganda or 'celebrity' trivia 'foam'. meanwhile; don't forget to get a little more oxygen on yOUR brain, & look up in the sky from time to time, starting early in the day. there's lots going on up there.

    is it time to get real yet? A LOT of energy is being squandered in attempts to keep US in the dark. in the end (give or take a few 1000 years), the creators will prevail (world without end, etc...), as it has always been. the process of gaining yOUR release from the current hostage situation may not be what you might think it is. butt of course, most of US don't know, or care what a precarious/fatal situation we're in. for example; the insidious attempts by the felonious corepirate nazi execrable to block the suns' light, interfering with a requirement (sunlight) for us to stay healthy/alive. it's likely not good for yOUR health/memories 'else they'd be bragging about it? we're intending for the whoreabully deceptive (they'll do ANYTHING for a bit more monIE/power) felons to give up/fail even further, in attempting to control the 'weather', as well as a # of other things/events.

    dictator style micro management has never worked (for very long). it's an illness. tie that with life0cidal aggression & softwar gangster style bullying, & what do we have? a greed/fear/ego based recipe for disaster. meanwhile, you can help to stop the bleeding (loss of life & limb);

    the bleeding must be stopped before any healing can begin. jailing a couple of corepirate nazi hired goons would send a clea
