Launch from the mun?

[Picooz]

Hello!

I hope this is the right forum ^^

Is it possible to start on the mun? Is there a mod for it or something? I have some stuff I want to try out but it\'s annoying to launch at kerbin and then fly to the moon and land.

Thanks in advance!

You can\'t start from the mun but to get there quickly to test things out you could modify an engine.

Maybe you can land once, look at the location data in the persistant.sfs file, then put the thingie you want to test on the KSC launchpad, save and exit the game and paste the mun-coordinates for that vessel.

Just an idea, never tried it and it\'ll probably end badly for lots of reasons, but maybe worth a shot

I have done this a few times and it does indeed work, it helps to have the capsule of the Mun rocket at the same height as the craft you intend to copy the data to though, as to avoid the new craft falling very far.

Just a few notes, Wordpad and Microsoft Word will damage the persistence file, so use something else.

Whenever modifying your persistence file don\'t forget to back it up in case things go wrong, you\'ll want to copy this section :

sit = LANDED

landed = True

landedAt =

splashed = False

met = 432311.805300157

lct = 1926.17995694653

CoM = 0.003766442,-1.178006,-0.0001837087

stg = 2

prst = False

cPch = 0.358, FLOAT

cHdg = -0.316, FLOAT

cMod = 1, INT

ORBIT {

INC = NaN

LPE = 139.201165147963

LAN = 71.7606741221753

MNA = NaN

EPH = 582105.640447331

REF = 2

OBJ = 0

}

: to the vessel you wish to move to the Mun, overwriting it\'s own data, there is just one thing you must change, and that is the stage (stg = 2 in this case) must be changed to the same number as the craft you are overwriting.

Edit: I forgot to add, the target craft on the Mun will have to be deleted before you load the file or both ships will be in exactly the same spot.

Hope this helps.

Does the vessel need to be in orbit already?

[Picooz]

I have the mod instant orbit but I can\'t seem to get it to work. Can anyone make a simple step-by-step guide for me?

[sal_vager]

The vessel you want to move to the Mun needs only to be on the launchpad, you\'ll then move the entire rocket there.

If you want to only move the upper stages you can either remove the bottom and launch without saving so as not to mess up your craft file, or you can get into orbit first and then edit the persistence file.

It\'s only really important that the craft on the Mun has enough room around it for the new rocket, and that you remember to change the stage so the rocket that ends up in its place will work.

KSP should handle the altitude if there is a small difference, with the new rocket automatically raised to the correct height, but if your target craft is tall and your new craft is short, you can find the new craft falling several meters with no time to start the engines and land safely.

As long as you make copies of the persistence file you\'ll be able to sort things out if they go wrong

About the instant orbits, which version are you using?

Foamyesque\'s is broken in 0.14.4, you may need to try Jellycubes here : http://kerbalspaceprogram.com/forum/index.php?topic=7844.0

When I edit the persistent file and save it does not show up in-game. And after doing this I can\'t go back from the tracking center.

Edit: I can\'t even launch anyting now without deleting the persistent file.

[sal_vager]

You\'ll have to restore the backup you made, you did make a backup like I said to do didn\'t you?

The persistence file can become unreadable if the info is pasted in incorrectly, it has to have all the brackets in place just as it did when you opened it, also some text editor programs can corrupt the file, I have been told Notepad works though.

You\'re intent here is to copy the location data from the ship on the Mun to the ship on the pad, I did actually forget something earlier in that you also have to delete the entire Mun ship afterwards, start from the line with VESSEL { and end on the line with } before the next VESSEL { entry.

If you don\'t do this you\'ll see both craft in the same spot, sorry for the omission

If you like, post the working persistence file before any changes here and I\'ll try changing it for you, you can attach it with the Attachment Options below the text box.

Oh! So I don\'t add the new vessel? I just overwrite the existing one? Alright then. Thank you!

[sal_vager]

Yeah, copy the targets vessel data to the new vessels data, delete the target vessel and hopefully it\'ll be the new vessel on the Mun in the target vessels previous location, if I were you I\'d keep a backup of the target vessel persistence info so you can quickly past it to new ships for your Mun testing, just past the info you need to a new file called Mun_launch.txt or something.

Good luck
