Mars In 39 Days via ...The Variable Specific Impulse Magnetoplasma Rocket.
Via The Fourth State of Matter, according to Dr. Franklin Chang-Diaz. Friend and fellow astronaut of soon to be NASA administrator Bolden. This new technology was mentioned during NASA confirmation hearings by General Bolden the other day. NASA Advanced Space Propulsion Laboratory "This plasma rocket drive is not powered by conventional chemical reactions as today's rockets are, but by electrical energy that heats the propellant. The propellant is a plasma that reaches extreme temperatures - 50,000º and above. Some scientists call this the fourth state of matter." http://spaceflight.nasa.gov/shuttle/...spl/index.html |

Cost of thrust is energy, mv^2/2 Outputting a propellant stream with relativistic velocity is a complicated way to burn money for the energy without imparting thrust to the space craft. Even idiot NASA is not proposing building CERN... In... Space! Here's the Head Start analysis, git: 1) You burn a megawatt to beam light from the rear with a purely enormous specific impulse. Are ya goin' anywhere? No. 2) You burn a megawatt to beam mercury ions and an electron dribble to the rear. Are ya goin' anywhere? No - and mercury will plate out everywhere, shorting all electronics and dissolving the craft by amalgamation. 3) You burn a megawatt to beam ionized SF6 and a proton dribble to the rear. Are ya goin' anywhere? No - and all the insides corrode away from liberated fluorine. 4) You burn a megawatt to beam xenon ions and an electron dribble to the rear. Are ya goin' anywhere? No - and price a tonne of xenon. Burning gold would be way cheaper. 5) You burn a megawatt to burn superheated algae with giant algae culture tanks baking in hard solar UV and cosmic radiation... idiot -- Uncle Al http://www.mazepath.com/uncleal/ (Toxic URL!

You know what quotation marks are right? He's an idiot, why do you say that? And it would be nice if you replied in plain English instead of your usual gibberish.

Negative fifty thousand degrees, ****nozzle. Gawd, it was a hyphen. Did you really read that sentence as meaning minus fifty thousand degrees and....above?

if it works.........
you build a solar explorer, it leaves earth and visits all the planets stopping in orbit at each one , perhaps dropping off a robotic explorer at suitable planets. a pluto explorer could go there then explore some asteroids. wonder how such a engine could scale up to redirect a planet killer asteroid? in any case we could be zipping around the solar system within 10 to 20 years, for robotic exploration.. mars in 39 days? hey how many are planning to take the new 4 month mars vacation? see the new mars explorers, a old viking lander site, how long to a nearby solar system? |

"Brian Gaff" wrote in message om... Isn't this stuff awfully dangerous as well though? I was wondering what people think of it, I've never heard of it before. The fact that Bolden brought it up in his Congressional hearings would suggest it's not some pipe-dream. And it's being developed by a long time friend of his a fellow astronaut which tells me this might begetting some real funding soon. I jus find it odd he brought it up, is this some promising new technology few knew about? Or is Bolden selling Congress some kind of bill of goods to justify the manned space flight program with on to the Moon and Mars? I think it was a song and dance to pump up support for another moon-shot.

You still aren't anywhere near a non-epsilon fraction of c so a bit of web searching for distances and some math will tell you the decades if not centuries or more involved. rick jones -- No need to believe in either side, or any side. There is no cause. There's only yourself. The belief is in your own precision. - Joubert these opinions are mine, all mine; HP might not want them anyway... feel free to post, OR email to rick.jones2 in hp.com but NOT BOTH... |
