You'd be surprised though, at how many intelligent people have misconceptions of gravity. Ask people what would happen to a pencil if you're standing on the moon and you drop it.

Trick question? A pencil can't be dropped on the moons surface.

Well, we're supposing you're in a spacesuit, so you can be on the moon's surface without dying.
Huh? The moon has gravity....
And that's correct. But you'd be shocked by how many people will say, "It'll float away." I've done this to a bunch of engineers and med students, and there's a large number of them that don't get it right. For some reason, no atmosphere and no friction somehow leads to the incorrect assumption of no gravity.

I already said I'm not an astrophtsicist. Deep space gravity is not my specialty. However conventional means at this point would be quite a haul for humans. Wed have to devise another way. However if repulsed by magnets, you could aim at any concievable point to account for whatever gravity may exist in the vacuum of space. If you have a better idea I'd like to hear it.
I think you're under the assumption I mean launching from earth or the moon when I'm envisioning something closer to a space station.

It's Cysko, I think.
It's Cysko, I think.
I guess if you guys are posting again it means my account us unlocked, but I kind of like this name better. Fwiw I'm an electrical engineer. However I'm just simply thinking of means to make the insanely long trip to mars more hospitible to human life

What does this stupid ass thread have to do with politics ???
It should be moved to the barbershop. Oh, wait, if I had posted it,
Zomblow the hypocrite would have moved it.

You don't need to be an asyrophysisist to know there is gravity in space lol
Even if you shot a craft off of a space station with magnets you would need a long ass rail to get up the the speed needed to escape the orbit of whatever the station is orbiting around and to just get there in a timely manner. Then once you are on your way you have no means of control or steering. You also have no way to get back.

You mean like a discussion 1 of our members wanted to have with his friends here about his new coffee maker?
Wait, maybe it was the 1 about popular music. That 1 even related to pop music has to generational politics.
This 1 has to do with politics since obama wants to dump the space program So we can afford to put every american on food stamps.
Even if that werent the case, I wouldn't move it.
Moving threads so far has only been used as a means to insult the member who posted it.
I don't plan to do that.

Oh, sure, Steve. Have a really nice valid reply, you ... you....
non liberal.
dammit.
Except Zombo will. He's taken sides. Can you stop that?

Actually pal, I don't know that he has.
I don't have that power from my moderator controls.
I don't know what T or Bunker posted or sent to force his hand.
I've seen Bonkers over the top garbage here so I assume his personal stuff was even worse.
As I've said before I believe T is an asset to the board as a participant.
I have not seen the offending post office is, but I assume they existed.

To me its a welcome change, even if my ideas are cockneyed, from talking about how Obama will make us all slaves.
In that note, woody, what's a better idea for getting humans to mars?

And it seems that most every one of these "non-political topics" have a way of turning into more interesting talks if you will!
I like em, and I think Steve has the right idea of allowing all posters a chance to have a say!

Here's an abstract from a paper out of Princeton that discusses the propulsion options to Mars.
In this paper, high-power electric propulsion options are surveyed in the context of cargo and piloted missions to Mars. A low-thrust trajectory optimization program (RAPTOR) is utilized to analyze this mission. Candidate thrusters are chosen based upon demonstrated performance in the laboratory. Hall, self-field magnetoplasmadynamic (MPDT), self-field lithium Lorentz force accelerator (LiLFA), arcjet, and applied-field LiLFA systems are considered for this mission. In this first phase of the study, all thrusters are assumed to operate at a single power level (regardless of the efficiency-power curve), and the thruster specific mass and powerplant specific mass are taken to be the same for all systems. Under these assumptions, for a 7.5 MW, 60 mT payload, piloted mission, the self-field LiLFA results in the shortest trip time (340 days) with a reasonable propellant mass fraction of 57% (129 mT). For a 150 kW, 9 mT payload, cargo mission, both the applied-field LiLFA and the Hall thruster seem reasonable choices with propellant mass fractions of 42 to 45% (7 to 8 mT). The Hall thrusters provide better trip times(530-570 days) compared to the applied-field LiLFA (710 days) for the relatively less demanding mission.
Here's the full paper.

To be honest, I have no idea what the hell any of these technologies are, and I'd only heard of ion thrusters on the Discovery channel maybe a decade ago. But it appears that your magnet proposal does have some application
-
All the technologies that have changed the world had plenty of detractors. Magnets may easily not be the answer but at least I didn't go full Retard

Announcing a tragic development with the Mars rover...

Watch out, some of our members may actually think that is a real picture.

There you go, woody, bumped. The magnet propulsion is MPTD.
