Comments on MagBeam Propulsion - To Mars And Back In 90 Days
Magnetized-beam plasma propulsion, or magbeam propulsion, could cut the time required for long journeys around the solar system from years to weeks. (Read the complete story)

"Great article and fantastic site. Congrats. "

"I don't see how one can keep such a plasma beam well-collimated (so that reasonable sized 'receivers' can be used) over such enormous distances without the need of external guide fields. How do you take into account deflections by intra-solar magnetic fields?"
(Barry Stallard (bwstallard@comcast.net) 10/20/2004 2:03:47 PM)
"Welcome to the Galactic Community! With the Ansari X Prize won and now our propulsion systems solved, us wee Earthlings can venture beyond our planetary borders. One more puzzle must be solved - Love Thy Brother! If we are worried about people from other countries in our own, how will we feel when we create the issue of people from other planets? Given that the age (birth -> death) rate will be differant in outer planets. Evolution is about to go wild ! Well Done on a Fantastic Discovery, anyone called Sir Richard Branson Yet? (Virgin Galactic) "

"this breaktthrough is mind blowing"

"So in essencewe could be there before we ever get there right? What I mean is, if the necessary deflector is infront of the payload as it is propelled to it's destination, then the apparatus for return is already there. Do I have it correct??? -N8-"
(Nathan Posey 10/21/2004 2:17:44 PM)
"That's exactly right! A ship using conventional technology would need to set up the station at the other end. This is not really an explorational technology.
In the Mote in God's Eye novel, the alien craft is accelerated using laser light pressure on a large 'sail.' When the craft gets to the next star, it uses the sail as a solar sail, to brake and steer.
BTW, I think that Robert Forward, who created the idea for laser-based propulsion also had a design for a way to decelerate using a laser beam coming from behind you."
(Bill Christensen 10/21/2004 11:34:45 PM)
"Does anyone here read Larry Niven? He's pointed out that anything worth doing in space - communications, propulsion, energy transmission - is an effective weapon. This is relevant to a beam sufficiently collimated to impart appreciable impulse at interplanetary distances. As a charged particle beam, it probably won't penetrate the Earth's atmosphere. So that's ok. Indeed it might have some value cleaning up low-orbit debris. Any thoughts?"
(Nile 10/23/2004 5:12:03 AM)
"Nile - Sure! there is lots of Larry Niven here. You might take a look at the Wunderland Treatymaker (on the subject of anything can be a weapon). I haven't heard anything else about "alternative uses" for MagBeam."
(Bill Christensen 10/23/2004 10:24:35 AM)
"The really sad thing is that back in the late 60's early 70's the von Braun team had the technology to make the round trip to Mars in about 30-45 days. Using Saturn V and follow on booster technology. Simple conventional rocketry."
(Jim 10/24/2004 11:08:08 AM)
"I see two potential show stoppers to this notion. First the idea of propagating a plasma jet out to an interplanetary craft is as tenuous as the plasma itself. Second, even if such beam projection were magically possible, the interaction of the plasma at the target seems to be determined by the "deflector system" similar to the mini-magnetosphere idea and real transfer of momentum to a solid object from plasma - magnetic field interaction has yet to be demonstrated. What keeps the energy from just being dissipated by plasma turbulence and eddy currents in the deflector magnets? Far preferable it seems to me would be the use of the HPH thruster directly in a plasma rocket that used a good nuclear power source and demonstrated good thrust efficiency and several kN of thrust at Isp > 30,000."
(R. E. Terry 10/25/2004 7:35:59 AM)
"The main problem i see with this idea even if it does work. is its limited abitity of flexibilty. First prob, is that you have to get up and down from the planets that you are going to, what more convention rocket systems just to achieve orbit with small payloads or landing through some unpowered means, tedious and time consuming and expensive. second, other than mars and the inner system and only when mars is in line of sight where else could you go as the asteroid belt would prevent any further use. Without flexibility and self containment your options become limited and a vessel without its own self contained propulsion would be at the mercy of to many variables leading to disaster. Why not attach the engine to the space craft and use it like a self contained sail vessel with its own wind. "
(wade young 11/1/2004 2:52:04 AM)
"I also think the risk that the decelerating magbeam will fail to high. Astronauts would want to control their spaceship in case of emergencies or changes during the flight."
(Ton Schuckman 11/19/2004 3:43:53 AM)
"Moving in the right direction. This will breed a new generation of systems necessary to support this advancement and stimulate the R@D community..."
(Desertwings@iwon.com 11/30/2004 1:30:07 PM)
"I think the solution is just not feasible: how do you think to send the magnetic propeller on "
(massimo 12/1/2004 12:02:00 AM)
"how do you manage to send a magnetic station on mar orbit?"
( 12/1/2004 12:13:53 AM)
"But how the first deaccelator will be puted on the end point?? It's look's like first mission have to take that 2,5 year on one side."
(jim 12/1/2004 3:31:45 PM)
"Interesting idea. If NASA can just overcome its infatuation with chemical rockets, it could be made to work, and be very effective."
(Keith 2/12/2005 7:35:28 AM)
"I hope we will be able to use this concept within the next 10-20 years. we could explore more than ever with humans instead of machines. good luck to the program."
(Austin 4/27/2005 5:53:06 PM)
"gone yersels a hope it works for yous coz if it dusnae thats more lifes youve taken resposibility for killing "
(douglas thomson 5/1/2005 6:12:12 AM)
"I like how sci-fi is close becaming sci-fact. It's real easy to be a negative skeptic but none the less u are needed. this doesn't mean rockets aren't going to be use , we could use the rocket to get to a space station that has the MagBeam and the MagShuttles that conects to another space station on mars orbit were u can dock and get on a Mars lander unit. Anything can is posible if we dont stop dreaming it happen once and it will happen againg. In 10 to 50 years."
(Dave (14 years old) 5/6/2005 11:41:38 AM)
"Hello there: My name is Mario Alejandro Faggiani I live in Argentina and i'm a aircraft pilot. I have to say to yours that This is the most great and fantastic proyect that I have heared in my life and it is a cool new propulsion systems. I would like to receive more information about it. thanks a lot Mario"
(Mario 8/21/2005 5:55:48 AM)
"This helped with my school project!
(You're welcome! Bill)"
(Marisa 1/25/2006 12:43:08 PM)
"This has amazing possibilities, looking forward seeing what applications arrise and when.."
(Carl 2/15/2006 9:25:31 AM)
"Solar powered power stations would be sort of unfeasable past Jupiter, wouldn't they?"
(Richard Tallino 2/18/2006 4:36:20 AM)
"I guess you could always make them bigger, gathering more light and therefore more power..."
(Bill 2/18/2006 6:25:50 AM)
"I wonder if it was possible to keep the plasma contained within field magnets and achieve propusion through the aceleration of the plasma with linier magnets along a limited distance allowing it to give a reactionary impulse that could be repeated at a uniform rate."
(Tom Yarbrough 2/21/2006 1:45:34 PM)
" In response with the Magbeam Project ...what I wish to imply is that the beam absorbing energy from a close star. And using it to generate a greater propulsion energy source. As it is - now and consistent with einstein's relativistic theory. The problem does not arive fom the problem of propiuslion in the degree of which the standing capacity to lightspeed atomic energy meets propulsion math figures. ou will find that it is the instinct of the ZPE vacuum spectrum that actomatically cahnges the energy content when traveling through interstellar space. Your facts relative to Einstein's would be complete if Einstein's mathematic figure;s were correct. But they are not.. What I nmean to say is - that interstellar space - in the planck scale equals 10 -34cm. The body weight of an object in space also chamges. reluctantly, if the capacity of acceleration in empty ZPE space is equal to Einstein's figure's based with Maxwell Plancks on ZPE. Then the interstellar medium acting from 6.6 grams CM to ZPE...is equal to the speed of light. It is the vacuum that increases the velocity of atomic energy propulsion and not a theme of technology..but awardable. The facts illustrates and according to The Quanta Physics Theory ..Proffessor Rod Kawecki phd..asserts that lightspeed capacity relevent to Einstein's equations - become automatically acessable on the entry of interstellar space. The mass relatiivistic feat for FTl propulsions are exempt in ZPE space. With that in mind - a ship traveling in empty space with the capacity to travel at lightspeed will do do automatically - under those terms in Einstein's formula - mention you exempt relativistic theory energy. I assure you my equations are correct. Consistent with relativity and quantum dynamics. The Quanta physics Theory - secures a FTL theorem based on the exempt relativistic gravity interferences we have on Earth. The way Einstein resolved his theory in 1906 his formula does not explain with the Quanta Physics format. It is for this reason I have developed this new formula.. Rod Kawecki phd...Los Angeles California.. The Magbeam propulsion project technology does increase the availability of propulsion power for the journey and is a great enlightenment for space travel. Refer to ...physicsamerica.com or special relativity quanta physics.com"
(Rod Kawecki 6/9/2006 5:34:57 PM)
"I think this idea is stupid. That means you have to have one of these things at mars just to propel the ship back to earth. And what would happen if there needs to be a course change in mid flight? There still has to be some kind of propulsion on the ship. In my opinion this is a waste of time and money. The ion thruster seems more promising than this. People need to take space more seriously. Just imagine the amount of knowledge we can learn if we had an effective means of transporation in space. The vastness in space is so huge theres bound to be other forms of intelligent life. Maybe they arent contacting us because we arent "advanced" enough yet? It makes me wish that I was born 200 years later. Becase at this current pace thats how long it seems that there will actually be any formable space travel."
(John 8/10/2006 12:31:21 AM)
" Lengthly space travel takes a lot less than what science writers call manipulating dark matter and creating wormholes. The science is already here. Its that the facts are not. Until " The Suopertellic Universe" by Rod Kawecki. STR and GRT is inconclusion in its facts. Shame on you. If velocity is weighed against the drive field grade than what's the light constant. Kawecki expalins why Einstein's work is inconclusive and resorts into his alternate theory in space travel technology."
