Jar files are normally executable. At least when Java is installed. Of course you have to make sure to have Java 6. I have heard that Java 7 (recent release) breaks Java 6 code. Anyway, please start if from a console/command line and attach a screenie of the command line/console output.

Got myself a more professional place to host the Calculator! Mediafire only gets you this far. And it's better to have two repos for development just to be on the save side.

Mehr acht oder neun. k;)

I don't really think that there is any need for a 'reentry calculator'. You just need to either go on a Hohmann into the atmosphere or point straight down. Anyway, I'm now halfway towards modifying the Stage calculators to include Custom parts.

Well... For me programming it serves two more uses then simply having a useful tool for KSP. One: Its useful for a Collage course on Object Oriented Programming, as the language in the course is Java. Two: It makes me do an in depth research on orbital mechanics that may prove useful for a little game that I have in mind for a couple of years.

Only because the orbital speeds of Kearth are relatively low and the moon would be rather far away. Looking at the Delta-v involved and the orbital speeds... The starting velocity is about 3300m/s, but when you arrive you are only about 5m/s slow. Yeah, could need 51 days on a Hohmann orbit. Also keep in mind that the actual Apollo missions did not follow a Hohmann orbit. That is in the planning stages. But first I need to make sure that I can read what custom parts are installed, rework the stage calculator accordingly to make use of those parts and then save everything in a config file so that the whole stuff is not needed to be loaded again and again. Not to mention clean up the code a little to be reusable. Then I will think about how to read .craft files...

Actually it would be the green dot. I expected the Velocity Vector to be the degree readout under the globe.

Exactly. At the moment that is not possible to actually implement. For the same reason the launch orbit calculator is experimental.

No problem. Feedback is always needed and wished.

There was a bug in the code that I did not notice. Somehow the inclusion of images for a window icon and the About dialog was broken by packaging up the program into a jar file. I'll need to look into it, but for now I have removed them.

Would be interesting to see a console readout then, when you try to start it over the command line.

Do you have Java installed? If yes, it should run without problems.

'Nother Update. V0.8!

That soooo going into my calculator.

'Nother update! Must be a weekend...

Take a look at my Java based calculator. It does Circular Orbits, Elliptic Orbits and Hohmann Transfer Orbits with Graphical overlay.

You should replace the USA flag and the NASA tag with the KSP tag.

UPDATE V0.6.6!!

Have you tried dropping the perigee into the atmosphere? That should get you down without needing too much delta-v.

True... Might be better.

update!

You are correct, Funk. Maybe I should add a help file to the program... Hey, it's as much of a work in process as KSP.

Exactly... So I marked the Launch Orbit Calculator as Experimental, until we may get a way to catch that angle...

Hmm... I think I may need to modify the calculator again... Just noted some explanations about that... Oh well... Gonna implement an elliptic orbit calculator anyway and a bug hunt is not much of a problem.

Did you unpack my calculator?
