Evidently, there are a lot of banks, analysts, and other people willing to commit great deals of money to things they can't see, but are guided by these principles. The fact that you are ignorant of their existence is not evidence for your position". Hey, sts60 What craps are you saying? Earth satellites are at a ridiculous distance in comparison with 500 million kilometers of Mars. You said you couldn't see a space probe a kilometer away, which, even if allowing for hyperbole - if you intended that, though I frankly doubt you're capable of such literary devices - is just silly. I pointed out that spacecraft on deep-space trajectories have been imaged as far as eight million kilometers away. In any case, the point is that the same physical laws govern the motion of Earth-orbiting satellites and deep-space probes, including those which go to Mars. If it doesn't work for a Mars orbiter, it doesn't work for the satellite which beams TV signals to the ground. Perhaps you are denying the existence of such satellites? Once again, you've made a statement out of ignorance, and tried to back it up with nothing but bluster. Quit trying to bulls**t us. Some of us do this for a living, but one doesn't have to be an engineer to see through your claims. BTW, Mars is never 500 million km away, not even close. Not that it changes the argument, really, but it does point out that you have yet to get even the most basic facts straight.

Hey, I'm not a conspirator, I'm only a little child that hates those who want to make game of me.
The earth runs at 100,000 kph around the sun along its orbit, Mars does about the same along another orbit, you can't see your probe, you can't see Mars but you are able to drive your probe to a target of 500 million kilometers distant. You are really little children that believe to fables. ;D ;D ;D

Rather than continuing to make yourself look foolish, I suggest you read the following Web page: www.braeunig.us/space/orbmech.htmAfter you've worked through all the example problems and gained at least a moderate level of proficiency, please come back to this forum and we will discuss orbital mechanics on an intelligent level. If the above Web page is above your understanding, then you have no business commenting on the dynamics of interplanetary trajectories.

Orbital mechanics is very interesting. It's a pity that you can't apply your theories in real world since you can't see the objects and then you can't execute any manoeuvers with them. What a pity, I'm really sorry. ;D ;D ;D

Orbital mechanics is very interesting.
And of great practical use. It's a pity that you can't apply your theories in real world...
Orbital mechanics is used all the time in the real world.
...since you can't see the objects
Yes, we can.
...and then you can't execute any manoeuvers with them.
The ability to execute manuevers according to the principles of orbital mechanics is the mainstay of a $50 billion industry.
What a pity, I'm really sorry.
No, you're clueless.

Hey, I'm not a conspirator, I'm only a little child Your first truly accurate statement.
that hates those who want to make game of me. We're not trying to make sport of you. We're trying to educate you. But you seem unwilling and/or incapable of learning anything, though. This, along with your uninteresting prose, makes your service life as a cat toy very limited to us.
The earth runs at 100,000 kph around the sun along its orbit, Mars does about the same along another orbit, Not quite "about the same", but you've stated the wrong problem as an objection, and it wouldn't be a useful objection anyway, and you would have no idea why in any case. But then again, understanding doesn't come from Google.
you can't see your probe, You've already demonstrated you have no idea how far out a probe can be visually imaged. In any case, you can see it just fine by its radio signal. So you are, again, incorrect. By your view of things, all my neighbors are wasting their time pointing their satellite dishes at those "invisible" spacecraft. How do you think they get their television signals? Magic?
you can't see Mars Mars is a spectacular naked-eye object in the night sky. Are you, literally, blind?
but you are able to drive your probe to a target of 500 million kilometers distant. Mars is never 500 million km distant from Earth. This has already been explained to you. And, yes, we can "drive" a probe there, or to Jupiter, Saturn, and beyond, with great accuracy. That's because there are people who actually learn and do things.
You are really little children that believe to fables. No, I'm an engineer, and I understand how it actually works. You don't. In fact, you seem to have much less than the average layman's grasp of how the physical world works. That's kind of an impressive achievement, in a weird Ripley's sort of way.

Can your software see the probe that is going to Mars? No, o.k.? How can your software drive the probe if it doesn't see where it is? ;D ;D ;D

With compliments. But explain how you can do it. ;D ;D ;D
