Hi there. A really annoying bug have occurred many times in my KSP. Sometimes while im in orbit i can't save a game or recover vessel or do anything but load another save. I'm able to steer my ship and do what i want with it. This thing happens even sevral times in a row: i saved my game while i was on trajectory to Mun and i couldn't saved anymore when i was on Mun's orbit. I tried to load previous save but it happend again. Please do something about it.

The challenge is as follows make the longest craft possible, and make it orbit. I want to see how far we can push the limits of this game. I will keep track of the scores in two classes: Stock parts only and Anything goes. To qualify for Stock parts only class you must adhere to the following rules: 1. All of your crafts may only use Stock parts (Obviously) 2. You must launch the craft from KSC into orbit 3. You may build it giant on the ground and launch it in one piece, or make lots of little pieces and assemble them in orbit. 4. No mods or cheats that alter the physics of the game or the parts. - Mods like mech jeb, navyfish docking alignment indicator are accepted. [5. No excessive space between parts] <-- should I add this one? (I think so) 6. Pictures or video of each type of craft at the launch pad, as well as pictures that validates your claimed score. To qualify for Anything goes: 1. Mod it, hack it break it, do what ever you want. 2. Picks or it didn't happen. To measure your craft I recommend you to use the navyfish docking alignment indicator. Take a separate craft and align it with one end of your long craft, set a docking port on the other end as your target, and read out the distance from the mod. If you have a different method however I will accept that, as long as I deem it rigorous enough. Top scores: Stock parts only: 1. neistridlar [600m] 2. 3. Anything goes: 1. qzgy [999 999 900m] 2. EpicSpaceTroll139 [ 6 973 597 m] 3. neistridlar [600m] 4. 5.

Hey guys, Bit of advice needed. I've been following Matt Lowne's video on making a basic SSTO So I made the craft he builds ( pretty accurately, same fuel tanks engines and a good COM / COL position ) but I'm having real trouble getting it into orbit. Now I'm very aware this video was made in 1.05 and I'm playing 1.3.1 - Are there big differences between the two versions that render the craft non viable or do I just need a lot more practice? Matt doesn't seem overly precise in his wander into LKO and onwards. I've yet to hit LKO. Here's my craft file: https://drive.google.com/open?id=18JGd3Mkp-Qc8Q8UCJ2lWNccSpZ_BLX2C On the runway I set the winglets on the end of the wings to have authority of 10% or it gets a little roll happy.

Today I tested the Kertimis Rocket! In case you were wondering, it didn't work. I don't know what went wrong, but I think one of the parachutes overheated and exploded, dooming all of my Kerbals to a firey death. Thank god for the Revert button! I'm still working on the Kertimis II, but it will be even bigger and even better than the Kertimis I! (note: I don't have any pictures)

Hello guys. Im new here . I've been playing KSP for about 22 hours now and It was amazing and I love it so much. So I pick this one contract and its called World's First contract. I've done a lot of World's First contract such as launching the first rocket,Orbiting kerbin and escape the atmosphere. But this one contract that don't understand.Which is the "Return to Kerbin from Orbit". Click "Note" and it says " Slow Down a vessel in orbit and return it to the surface to achieve this goal" . How? What kind of ship should I design? Thank you

I don't know you but each time I have to launch into a specific orbit inclination for contract mission, going to Minmus .... I am facing the problem of when will the ascending or descending node will past over the KSC to permit a clean direct orbit inclination without modification once in orbit. I asking you if there is a way to do that in the stock game or if a mod allow you to know that and if it is not ,if it is possible .

so i got a contract to get an unmanned space probe into an equatorial orbit around the mun, but it wont complete. it says my apoapsis must be 232,000m and periapsis 211,000m and i have met these down to the nearest 100m and my inclination must be 180° which for all i can tell it is, give or take 5°. any help is much appreciated, thanks.

how can i make that my two Rockets are on the same place? (in orbit) http://prntscr.com/hvbnel point (green) (blue)

So I recently borrowed a friend's internet to update my KSP from 1.0 to the current version and get all the mods I plan to use, and I'm noticing that some techniques I used before to get things into LKO are not working anymore. So my question is this: I have a large (180 ton) interplanetary science vessel parked in a high orbit around Kerbin and, after returning from a low space flyby of Eeloo, it has just enough DeltaV to deorbit itself, and not much else. It runs on nuclear engines and I need 16,000 units of liquid fuel to top it off, but I am having a DEVIL of a time getting that much fuel into orbit. I guess I was so excited to finally get it into orbit and do some 'splorin that I didn't think about how I would refuel... Any tips? EDIT: I suppose I should clarify what exactly the problem is. I'm trying to do this in as few launches as possible to avoid running out of funds. I guess I could do a bunch of rescue missions and whatnot but I just want to fly around in my capital ship lol

This is very simple. Place at least one Kerbal in orbit, using ONLY the LV-N engine for propulsion/impulse. Lowest launch mass wins. Go.

This may have been asked, but is there anyway to establish an orbit around a particular space station?

I just bought KSP yesterday, and I can not create nodes of maneuvers, my apoapsis points should be blue except that they are gray, so I can not create a node by clicking. Can someone help me?

Hello ! I made a geostationary orbit in ksp with 3 satellite around kerbin, It was working well until I leave my save and come back on it : The 3 satellites wasn't separated by 120 degree as before but the 1st one was like 20° from the 2nd and the 2nd was 35° away from the 3rd and last one.. I did not changed the gravity in debug panel or anything like that so I don't know why is this happening...

I'm trying to recreate a KSP-like game in Java, and I have no idea how KSP calculates Apoapsis, Periapsis, etc. when your ship is moving in space.

Greetings, Messing around making a space sim game, but in the orbital calculations, atm im a bit stuck with if eccentricity is actually a vector depicted in a 1x3 matrix with I J K But ive often seen it refereed to as a scalar/magnitude. Im using the formula here

I know others have done it and I won't be the last either but I was particularly please with this result. Having rescued Parey from the suface of The Mun and Oremy from orbit of the same I let them have a few hours R & R and snacks aboard the space bus docked at Babylon K ( Only Parey was granted access to the K proper due to the all female crew, no boys allowed! ). Once refreshed they were taken by Space Bus ( previously Level Up Bus in another thread but renamed ) to Kerbin Orbital Station where they transfered to a rocket bus flown by Valentina. As Valentina had a go at throwing the ship at the KSC. The results were better than expected. At 7km up things were looking very promising! Then at 1100 meters she remembered that she should probably open parachutes at this point. The final result being a gentle touchdown on the landing gear just 1.8km from the VAB

So, I"m not sure if this is a bug, or if this is considered normal, but I cant seem to complete tourism contracts that require you to orbit the sun. I've figured out a work around, but it doesn't seem quite right. My problem is that I can not get "Orbit the Sun" mission parameter to go green, even though I'm clearly orbiting the sun and do not have any encounter with any planet. I get "Flyby the Sun" to complete, but "Orbit the Sun" will not complete UNLESS the kerbal's vessel is the active vessel when orbit is acheived. Like I said, I've been able to figure out two ways to make it complete once I am in orbit around the sun, but I shouldn't have to do it this way: 1) I had a transfer stage that had a lander docked to it that made it to solar orbit ("Orbit the Sun" was not complete for 2 tourists). The kerbal tourists that needed "Orbit the Sun" were in the lander. The transfer stage was the root vessel. I undocked the lander from the transfer stage and suddenly the two tourists mission parameters of "Orbit the Sun" went green. 2) On another occasion, i didn't have the same lander/transfer setup so I couldn't just undock. I set up a maneuver to re-enter Kerbin SOI, then right after I'm in Kerbin SOI, I set up another maneuver back to solar orbit and just keep the vessel active while it leaves Kerbin SOI and enters Sun's SOI. I've tried playing around with KLM to see the data in the save file. It appears that my kerbal's are not getting "Orbit,Sun" attribute added to their Roster / Flight_Log. I was thinking maybe there was something with Kopernicus causing an issue with solar orbit identification, and I tried removing that, but it didnt help. Does anyone have any other ideas as to what could be causing this? Here is my Game data directory and a screen shot with some "proof" of flight condition/situation.

Just wondering if any maths / rocket surgery people out there that might be able to point me in the right direction for formula to work out the following for an airless body in KSP. The question I'm trying to work out is for the bodies in the game that allow a Synchronous orbit, and given the limiting factor of SOI of the body, how close could I get to the surface with a vessel using an Eccentric Geosynchronous orbit? ie something like a Molniya orbit that had the same sidereal duration as the body it was orbiting.

I am designing my first Mun Lander. I am using Kerbal Engineer Redux and I've had a look at the dV chart. I've decided on a 3 stage 2 Kerbal mission. 1) The lifter - Carries the two other stages to LKO ~ 3500dv 2) The transfer / return stage - Carries 2 Kerbals Lander will be docked with this. ~1500 dv 3) The Lander - Carries 1 Kerbal - has a materials bay, goo, temp, barometer, and seismograph. 1400dV (600 dv land 600dv up and 200 spare for orbit maneuver and docking ) If I'm understanding this correctly then I need about 600dV to reach land on the Mun from LMO and presumably the same to get back up plus a safety margin for docking? And I use KER set to Mun to calculate my total dV?

Hello everyone, I'm having some issues while playing ksp, when my ship (stock or costum) is in orbit arroud any planet or the sun my screen gets black. I can still control the vessel and the navball and other instruments are still functional, however I can't see my ship nor the planets, sun, etc. I've recently noticed that when I engage the vessel engine or RCS thruster, the gameplay gets normal again. Does anyone has faced this problem before? I took some pictures of the problem, maybe it will help. https://www.dropbox.com/s/z5v0vbmz02s73qe/In orbit 2.jpg?dl=0 https://www.dropbox.com/s/fgiy9eft3904kia/In orbit.jpg?dl=0

I have a couple of questions about the above. When circularising my orbit above Kerbin should I also be checking the inclination and if so what should it be at for the best transfer orbit to Mun? Often when I burn for the Mun I find the encounter is going to kick me up at around a 30-45 degree angle. Going for a capture burn at periapsis then puts me in a heavily inclined orbit around Mun. This is ok for tourists and small satellites when I have plenty of dV to spare but I'd like to do things more precisely. May I have some tips on getting a more equatorial orbit around Mun?

I have no idea what has happend to my map, but it is really annoying. I have tried to restart the game and uninstall some mods, but it still looks like this

I'm losing my mind. I have a contract to match orbit, and I've matched it visually and painstakingly precise, but I'm not getting credit. I'm matching the correct direction of orbit: Any ideas? Here's a screenshot:

Hello everyone, Is there a way to make orbit in RSS? I was worst at making rockets (probably) and I hope you guys can give me some tips.
