The only person here not understanding the basics is you.

That’s why everyone else is able to provide links to pages on basic orbital mechanics, and all you can say is “iTs ImPosSiblE!”.

Why do you think you know better than everyone who studies it, and everyone who launches satellites?

You’re no different from the flat earthers who don’t believe in gravity at all. The problem isn’t that you’ve come across something you don’t understand, it’s your stubborn refusal to even try to understand it. You just keep saying you’re right and everyone else is wrong.

Sorry, I know very well what an orbit is according Gallileo and Newton. It is an object flying around a celestial body, e.g. a planet around the Sun, a moon around a planet or a satellite around Earth. The orbit can be round or elliptical. The dynamics of it are easy to understand if you believe in gravity (a force that attracts masses).

This Holman transfer of a spacecraft moving between two planet orbits (Earth and Mars) you refer to is not proven. The spacecraft cannot get away from Earth as suggested (it will always orbit Earth at variable speeds) and, if it arrives close to Mars in its orbit around the Sun, it will just crash there.

What are your calculations for the transfer not working? All you ever say is that scientists won't return your voicemails and that it won't work. You never say why it won't work.

What's incorrect about this:

Show us how the calculations are incorrect. Otherwise, you have no challenge.

I have done at my website since many years. "Gravity kicks" and similar are pure BS. Don't tell me that space travel is to orbit from planets to planets and be kicked to the target by gravity kicks?

What space travel sect do you belong to? NASA? ESA? JAXA? Or the Russian one?

Why don't you show us here how the calculations presented are incorrect? Again, you just saying so does not suffice and does not make for a challenge. You have no challenge until you can show where the errors are.

But I do it at my website. Visit it! I cannot copy/paste it all the time.

Topic here is orbits and how they work.

Do you know what an orbit is?

Good.

All things I know in orbits like planets, moons, satellites, space garbage have always been in one orbit from start to end since billions of years. I have never known any object that can transfer from one orbit to another. And why do it? Why not stay in orbit?

I checked. And no, there are no calculations on your site that refute these calculations. Address these calculations presented directly. Where are they wrong? Without your calculations you have no challenge.

Please check again. All calculations are there.

I did. There's nothing there. Post some calculations you have that address and show where the ones posted here are incorrect. Otherwise, no calculations means no challenge.

If you want to have a thread here then you need to address things here. You can't just say, "Oh, just go look at X site...". Especially considering it's your own site. You need to be able to respond directly.

? I thought I explained the **Gravity Assist Kick** fraud at http://heiwaco.tripod.com/moontravelc.htm .

No, you did not provide any calculations. All you say are things like, "The gravity assisted kick/slingshot nonsense was probably invented by some NASA science fiction writers in the 1950's not knowing much and is now taught at US universities as astrophysics. It is comical. Every time I meet astrophysicists, I ask about gravity assisted kicks. They cannot explain them!"

That's not a calculation showing how transferring orbits is impossible. It's you just saying so because someone won't answer your questions or return your calls and you're not an astrophysicist - Because they know they are obviously dealing with someone who has crackpot conspiracy notions. Why bother.

Unless you have some calculations showing how the presented calculations are wrong, you have no challenge. No calculations, no challenge. Your opinions do not amount to a challenge.

Do the calculations and let us know when you actually have a challenge. In the mean time, none exists.
