Sorry for the late response. Please download my spacecraft from the following link and test if you have the same problems with it as me. http://s000.tinyupload.com/?file_id=95574433043516141547 Thanks a lot. Cheers

Those of you who want to test my craft can download it from the the following link (hope it is working): http://s000.tinyupload.com/?file_id=45181572118438041047 I'm excited about your experiences! My idea was as well, if it is a phantom force from some part, this force should always be directed into the same direction relative to the craft. Therefore I already tried to point it into several directions for a short period of time, but it made no difference. Than I was thinking: relative to Kerbal, the craft is always pointing into a different direction (if SAS is on; if it is off, the craft shall not rotate) on one orbit and the mysterious force should lift the orbit on one side of the Kerbal and lower the orbit on the other side of Kerbal... am I right? Therefore the effect should be deleting itself, but there is definitly happening something. @Aethon: the procedure you described seems to be very annoying. But I don't want to redesign the position of the OKTO. I was very happy to get it to this location!

thanks vexx. @starwhip: I have cheated a bit with the modular girder segment... I hope this is not causing any problems, it never had until now. Unfortunately I won't be able to upload something in the next few hours, so don't wait for it (but please don't for get me... ;-) ). Cheers

UPDATE to show my spacecraft and the problem I have managed to upload some pictures, see attached. I have launched the vessel again to make some other pictures. I have now choosen a higher orbit, to see if the problem still occurs. And, yes, it is, but much less. But this doesn't matter. In my oppinion, nothing should happen, or am I wrong? In this case, I can't park a probe on an orbit of 80km. What if I have to warp a different probe for 1 year... this one wouldn't survive. Indeed, it is mor realistic, but it shouldn't be the case! The first picture has been taken right after injection into the orbit and the second after one full orbit. As you can see the Periapsis is now 60m lower and the Apoapsis 40m higher (latest update: PE 220m lower, AP still +40m). So, this vessel would have an PE of 69000m after 200 orbits. I am sure, the values would be greater if I would be in a lower orbit. The third picture has been taken after the second orbit, which I have warped... and, compared to the first picture, not much has happened... isn't it interesting? Ah, and btw, the orbital period is also getting faster... Is my TWR changing because of the differents hights I have during one orbit? I have not yet changed the configuration to test if something will be different... I will do next. Regards, Johannes

OK. Thanks. I'm sure every throttle is at zero. This was of course my first idea and I have checked this several times. I'm using EngineerRedux-0.6.2.12 and KerbalAlarmClock_3.1.1.0. Next thing I will do is to run Kerbal without those mods. Maybe going to warp will help as well, I haven't done this during setting nodes. If nothing helps, I will upload this vehicle that you can test. Cheers

First of all, thanks for your answers. You have probably already noticed that I am new in this forum and I'm not yet familiar with every option here... I can't see my original post, is this normal? I would like to delete everything related to the pictures I have mentioned. Sorry about the pictures, I was not aware that it isn't working like this. But I think you understod my problem anyway. However, unforunatly, nothing is fluctuating. The orbit is contiunously decreasing. And it is not a small amount... a few metres in a few seconds... this means it is decreasig 2000m in half an hour. It makes much sense if there is a phantom impulse created by a part. Can this be done by any part, or does it hase to be an engine? Regards, Johannes

I know what you mean, but this is not the case! Nothing is fluctuating, it is continously decreasing, even on a higher orbit.

Good day forum members, I have an issue I have never heard about... My orbit of one spacecraft is getting lower, although Periapsis and Apoapsis is above 70km. While trying to achieve a path to Minmus (I spent a lot of time to this), suddenly my spacecraft was in an orbit within the atmosphere of Kerbin and decreasing fast, which confuses me. I was trying to find any way to Minmus, which costs less fuel as possible, therefore I made some screenshots during gaming, please see attached. You can see, that within a few seconds (the time between creating the screenshots), the Apoapsis was getting from 72,797m to 72790m. Afterwards I burned up to an orbit at around 85km and the same problem appears. I think, this should not happen and it shouldn't matter what kind of spacecraft I am using. FYI, every engine was shutted down and no RCS was activated. So, please tell me, what is going wrong and what can I do to solve this issue. Thanks a lot, Regards, Johannes - - - Updated - - - Unfortunately, posting the images didn't work, but that doesn't matter. I think the issue is pretty clear.
