Rosetta's Philae probe makes historic landing on comet

It took me 10 minutes to search those publicly available reports and compile that list. I am not impressed by your ignorance and laziness at all. You obviously know nothing about space flights heywee!

Using http://sci.esa.int/services/36371-search/ + Rosetta Status Reports I just get 8 pages of reports in no order at all and very little about gravity assist kicks.

Eat your own words first and then I'll help you find those reports.

The reports are a joke! Written by some SF writer with little knowledge of physics for young boys to fantasize about. So all details of the gravity assist kicks are left out. It is just said they took place and everything went fine, bla, bla. The last kick is hilarious ... Rosetta flew over the South Pacific at 2 500 000 m altitude and was kicked away to comet 67P.

Not quite sure what is hilarious about the last gravity assist occurring at 2,500km from Earth?

You didn't believe that Rosetta burned any fuel for each kick. Now that I showed you that Rosetta did make several trajectory correction maneuvers for the first gravity assist, you still didn't understand how that kick could happen. Listen heywee, the fact that you don't understand it, it doesn't mean it didn't happen. And to be honest with you, we can clearly see that actually you don't understand quite a lot.

There are contradictory reports about Rosetta correction maneuvers and fuel consumption. ESA uses the NASA/JPL favourite term nominal that can mean anything like inconsiderable. Fact remains - a gravity assist kick is not possible in space. Particularily not over the South Pacific!
But thanks for your input.

Why not over the south Pacific?

What's impossible about a gravity assist?

What contradictory reports?

It is explained at my web site. Pls study it!

As mentioned earlier, stop forcing us to visit your malicious website. Please copy the relevant information here if you want to debate here and answer these questions:

What contradictory reports?

What's so special about South Pacific?

Not to mention your website needs to be reorganized. Information is just thrown around with no order.

That website is also just one page.  It would probably be a good idea to organize it a bit.

Thanks for your cooperation.

So let's await the reply by ESA.

Why would you expect a reply from ESA when you provide a link to a (popular) web site that calls the entire Rosetta program a fraud and the ESA director general a clown?

Also, it should be pretty obvious that it's much more efficient to make small mid-course corrections far out than it would be to make large corrections just before the gravity assist.

That website is also just one page.  It would probably be a good idea to organize it a bit.

Hey, mikeman, since you did apparently venture there, is there advertising on Anders' site? Given all the pimping it gets, he must be paid by the page view. If there's no advertising, the question becomes who and, perhaps more important, why?

Don't go back just to answer this question, just say if you noticed any ads. If there are and you remember who, that would be useful to know.

I am an optimist and hope somebody at ESA will provide the missing info about the impossible gravity assist kicks that evidently never took place. The whole project is a fraud! No Rosetta in space. Human space travel is not possible and robotic ones like Rosetta much too complicated to do.

Better to get the kick right in the first place with no corrections later. But you always run out of fuel any way you do it and there are no kicks.

I checked out your link to the €1,000,000reward thing and at first I thought that the reward was to disprove the Gravity assist kick thing which I could develop a program to do, but unfortunately it's about the 9/11 incident and I actually believe that it was caused by the government anyway, so darn.  Programs take a lot of time and energy to write, so I don't want to write an orbital simulation program just to prove a point.  If I am mistaken and the reward does extend to proving that gravity assist manuvers are possible then I will start development of the program imediately and I will even show my source code so people can make sure that I did not cheat.

I'd say that you're lot more than an optimist if you insult an agency that you're trying to get information from.

Actually, it's better to design a space probe to carry enough fuel to make any mid-course corrections that you might need.

Why would anyone waste the effort when you've already proven that you will never accept any evidence that you're wrong?

The Challenge #2 is about human space travel in 3D and, if you require it, gravity assist kicks. You can always use the Moon to demonstrate anything about gravity assist kicks, e.g. they do no work, really.
Moon is too big in 3D (and not a mathematical point mass in 2D used by many astrophysicians) so you will spin off in an unkown direction, if you try. You know - you cannot ever collide with a 1D point in 3D or 2D.

Why would anyone waste the effort when you've already proven that you will never accept any evidence that you're wrong?

Just try to win the my Challenges and prove that I am wrong. I will evidently accept that. I am quite certain that I am right though but ... you never know. That's the Challenge. And you do not waste your time by using your brain a little now and then (in lieu of writing stupid comments at this forum without any thought at all).

If I were to write a program to simulate a gravity assist manuver only using the gravity equasion and Newtonian laws of motion would that be enough to get the reward?

Study the requirements:

"The Anders Björkman Challenge 2 is first to calculate the amount of fuel (or energy) required to complete a manned Moon and/or planet Mars return trip after being ejected into space from Earth towards the Moon and/or planet Mars by external rockets and second to describe the space ship incl. heat shield, its engines and fuel tanks that can carry that amount of fuel using 1960 or 2014 technology."

Note that you can use an external rocket to leave Earth but then your spacecraft is on its own. Easiest is just to copy/paste the 1969 NASA Apollo 11 Moon return trip! I wonder why nobody has done it!Maybe it was all fantasy? Like the Rosetta!

You must first prove that you have the money heywee.

Here is a possible Challenge solution to go Mars (or its Moon) and back using gravity assist kicks !

You send your Mars spacecraft to the Earth Moon for the first kick and direction change back to Earth - speed increases! The second kick is with Earth with a direction change back to the Moon. After a few kicks between Moon/Earth your space ship has reached a very great speed using no fuel and you kick your self away to Mars (or its Moons), where you arrive after two days.
At Mars you use the Mars Moons to kick your speed down to almost 0 again, so you can land on a Mars Moon. You must have enough fuel to land and to get off a Mars Moon, but then you can kick yourself back to Earth using  gravity assist kicks ! Gravity assist kicks provide free energy, you know!

But maybe the high g-forces applied at every kick will kill you?

You must first prove that you have the money heywee.

Put the money into an escrow account, accumulating interest, which will be held by a court appointed committee of referees until the prize is awarded. Publish a clear acceptance criteria which can be verified by the referees.

Once you have done this, I will hire the best rocket scientist in the world and share the prize with him
