I've been trying to create a mobile refueling rover. However, I cannot get the ports to work to attach my craft for refueling. I figured maybe I attached them incorrectly or something, so I went back to the sandbox and pulled up the prefabricated crater crawler, which have built-in docking ports. As a test, I have two of them (with extra fuel tanks) just off the Kerbin runway. My plan was to test the concept and see if I could transfer fuel from one to the other. However, I cannot for the life of me get the ports to work. They just bounce off each other. I have set one as a target; I have tried "control from here" and no luck. Earlier, I had played around in a different scenario, where the ports would attach but upon decouple, would explode. This time around, they won't even go together. I am very confused. Interesting, as well. It says they are 5.8 meters apart, but they are touching. Is that distance figure based on the command modules and not the ports themselves?

I've had a problem with controlling ships when controlling from docking ports at a right angle from the root part. Both SAS and mechjeb's Smart ASS have wild oscillations around the roll axis of the docking port, like its overshooting its attempt to stop rotation. This happens with both an inline docking port part like the shielded clamp-o-tron or with a normal docking port attached radially. I might try testing this in an unmodded install, but was wondering if anyone else has experienced this? I have several mods installed but the only one I can think that would effect SAS's ability to hold steady is mechjeb. Nothing out of ordinary appears in the logs Edit: this is in 1.3.1 since I'm still waiting for mods to update

the mission consists in: docking to a target, undocking, redocking, undocking, redocking. the result is unpredictable, sometimes it works some times not, maybe you get the first 2 right but the third bugs, and so can't move on. I kept trying and retrying, but still I can't manage to find a way that ensures completion to the task. Sometimes it seems that it is related to a vehicle modification before mission test, so I deleted and recreated the docking tests dozens of times, but only sometime it seems to be the solution... In the screenshot you can see the project. During the last 2 tests the ATV-gemini dock has worked fine, and triggered the message, but "undocking 1" dind't work the first tima, and not even in the second after I tried to recreate it. I just don't get it, it has the same vehicle specifications of the other, but it fails.

Has anyone else experienced the following problem in the mission "Meet Me in Zero G": The "Undock NOW!" node will not activate for me. I can undock immediately after the dialog message instructions, with no result. after then waiting for a bit, the time since node activates, I get a 0.7 score multiplier, and the waypoint for KSC never activates. Removing the undocking node and replacing it with an identical one fixes it for me.

Is anyone else finding it way less forgiving to dock since the update? Where the vessels used to bounce a bit and slowly orient themselves with the magnets... Now they drive into each other and starts spinning frantically out of control.

Hello, I just launched a rocket into space trying to dock to my small space station. Now i managed to get there and also pretty much dock but i realised, that i put my RCS thrusters (Place Anywhere RCS Port) onto my Docking port on my Rocket which doesn't allow me to dock. I've tried it multiple times but it always got stuck with the magnetic force active but the vessels not connencting. Is there any way to solve this or do i have to do this mission all over again? Thank you in Advance

Hi everyone, I just bought this game a month ago and still tied to it haha, here is my issue, I'm triying to complete the contract regarding dock 2 veesses arround kerbin, so 1st I launched one vessel, then send the other, after some time I managed to circularize the orbit and match both vessels in the same pattern (same AP and PA) however.... I don't how to make them encounter(see attached image) if I burn retrograde then the orbit will change and won't be able to reach any of the vessels... to get the things worse....KSP saved automatically so all my pilots are outthere in kerbin orbit (I wish I could save a game before). I would like to know if anybody have some suggestions / advise on how to dock in this scenario. Screens are in spanish(sorry)... but you should be able to understand velocity and distance meausures Vessel1 have aprox = 3590 m/s DeltaV (remaining deltaV ) Vessel2 have aprox = 2506 m/s Deltav(remaining deltaV ) Hope anyone can provide some suggestions.

In my ongoing career, I've had a number of brushes with the Kraken when dealing with space stations. There are three scenarios in play: Docking. The Kraken strikes immediately after docking. The giant invisible tentacles wrap around it and shake shake shake until it falls apart. Undocking. As above, but on undock, and only one craft is directly affected (although the other might get damaged by flying pieces of rocket). Fuel transfers. This starts with a tiny insidious little vibration as fuel is transferred from one craft to another. Sometimes it stops if I quickly stop the transfer, at other times not. If I'm connected with the Klaw, setting Free Pivot may or may not help. Some hypotheses I've come up with: Scenario 1 happened with a long skinny station when I docked another long, skinny, but heavy craft to a port near its centre. Even though the docking event was at a low speed (0.6 m/s or so), the bump appears to have induced an oscillation along the length of the station, which then amplified into a full-scale Kraken attack. Possible solutions: don't make long skinny stations? If you do, don't dock heavy craft near their centrepoint? Scenario 2 happened repeatedly when undocking a heavy spaceplane from a station, or when undocking a cargo module from a heavy spaceplane. I believe I traced this down to excessive use of Autostrut to Heaviest Part. When I undocked, the heaviest part was removed, the autostrut reconfigured itself, and the rapid changes summoned the Kraken. Possible solution: don't use Autostrut to heaviest part, or only use it sparingly? Scenario 3 happened repeatedly in scenarios where I had a heavy craft docked to the station orthogonally and was transferring fuel between the two, which shifted the CoM laterally. I'm not quite sure what the contributing factors to this are, except that Autostrut to Heaviest Part certainly makes it more likely. What techniques are you aware of that would make stations less prone to summoning the Kraken, apart from being very careful when using Autostrut to Heaviest Part? Which geometries are more Kraken-resistant? How do you configure a station that has lots of docking ports to accept different kinds of incoming craft, but doesn't summon the Cosmic Dread Lord when large craft dock with it?

Hey guys, I'm sorry if this was asked before but I'm just losing my mind. I recently started building my space station, it has living quarters and a science module, connected by a Rockomax Multihub connector. My problem is, because of the idiot that I am, I forgot to add docking parts to the remainder of the ports of the Multihub connector. My question is, is there any way that I can attach a docking port to the remaining ports of the Multihub connector? Or do I just destroy that space station and build another one? Thanks

Hi, A couple days ago i found this bug in my current game: Both the rover and the trailer were created as part of the same ship originally, once in Duna they were decoupled independently and i docked them later to transfer LFO to the scout rover from the mining trailer. The rover appears to float after undocking, but it is still connected to the trailer. When time warp is activated all the rover parts return to the original position as if it were docked. I'm playing 1.3.0 x64, with just one mod installed, KJR v 3.3.3 (up to date). I tried to delete the mod and load the scene again, but the rovers have the same behaviour, so i'd say is not related to the mod. I also tried to modify the persistent file using KML 0.7.2 to fix all the docking bugs, but the problem persists. Connecting another rover with a claw didn't fix anything either. Any ideas?

I have played KSP for quite a while now (and love it), but only recently have started using docking ports. for a minmus mission I decided to go with a lander vessel on top of a large carrier vessel joined by two docking ports. I tested it in orbit over kerbin, and it I could undock and dock it with no problems, except that after docking again the stages of the lander vessel are merged with the stages of the carrier vessel. Is there a way to prevent this from happening? Or should I build the craft differently (Now I have built both in one go, no subassemblies)? What I would like is the staging sequences of the two vessels to be kept separate. I don't even need to see the stages of vessel2 when controlling vessel1 (and vice versa). Hope someone can advice.

So this problem arises with my folding wing SSTO, and the basics of it are that after undocking the bottom ports to fold the craft up, it refuses to fold back down as the docking ports haven't moved 10m from each other. Any tips other than f5 + f9? Id greatly appreciate it if 'theres a mod for that' came into effect here.

Hi there, I've poked my head into the KSP forums a few times, though have omitted a formal introduction as such. So here I am. I'm an engineering school dropout and had been lusting for a game like KSP ever since I had spent weeks on end playing "Buzz Aldrin's Race into Space". I've been playing KSP (badly) for a while, sandbox only. It's one of very few computer games I can still play, as I've lost most of my vision in a traffic collision a few years ago. Consequently, when I bought my present computer, I hadn't expected to play any graphics intense games again, ever. Consequently, not the hottest graphics card. Which you can see in my first KSP video. Well, more like my seventh KSP video. Just the first one that is even remotely watchable and that I didn't have "Eraser" scrub from my harddrive. What you see here: A mission to the mun. On rockets under 500 tons. Yes, the plural. I'm dead certain somebody else has done this, probably when the game version was still below 1. But here's how I did it. No engine with ISP over 310s, so in the Apollo-era ballpark. Rockets weighing about half what the RSBstock Saturn V brings. I don't play career mode, but if you have to make a Munar landing happen with smaller rockets, here's an option. The mission profile: Jeb flies to the Mun, alone, in a 2-seater spacecraft with plenty of ∆v to spare. In case something goes wrong. What would go wrong would be part of Valentina's flight. On a second rocket, carrying the actual Munar landing craft. After flying to the Mun and landing, she goes back up with the ascent stage, and then heads to rendezvous with the waiting Jeb. The rest of the mission should be obvious. Not so obvious, until I flew it for the video: Taking off from the Munar surface, Valentina had enough ∆v left to make it back to Kerbin without Jeb and his big rocket. So I might use the hardware from this video to try a direct ascent flight in a later video. If such is desired, please do let me know. Anyway, here's the video. Caution: The title is no joke. Clumsy is, also, not something you do with your hands. It's a state of mind. So even where I had the right idea about how to do something, I certainly did it in some way that will make you cringe so loud, your neighbors will file a complaint. So don't watch this if you don't wanna deal with being subpoenaed over noise pollution.

I'm new at this game and it was really fun until I got to the docking training. I can't for life clear this stage. Struggle to get the interception markers correct and if I get them correct I will never ever get near the stranded ship, maybe I see it and then everyhing goes really wrong. I follow the guide point to point but no luck at all. Right now I feel that this is the most money wasting game I ever paid for. I know it will be hard to dock but to clear a training session? What will motivate me to continue playing this game if I can't even clear the trainings... Can someone give me a step by step tutorial on how to solve this stage?

I have a mission to "build a new unmanned probe...". My plan is to make a spaceship with one kerbal and an unmanned probe attached, so that I can position the satellite and bring some science data back as well. But when I reach the designated orbit and have the unmanned probe un-docked, the mission requirement "build a new unmanned probe..." is still not fulfilled...... The probe has everything required (probodobodyne, solar panel, antenna). And if I remove the kerbal before launching, the "build a new unmanned probe..." is immediately fulfilled when the spaceship is on launchpad. Is this a bug, or I have to launch it with no kerbal to satisfy the "unmanned" requirement?

I would like to make kerbals come out from docking ports, but I have no idea on how to force them to do so or if is it even possible.I appreciate alternative ways if this is not possible.Thanks for you support.

Hi KSP Community.I have a problem: I have to dock two big fuel tanks (around 6-8m diameter) in orbit for a trip to Mars.Realism Overhaul gives you pre-sized docking ports and TweakScale can't modify them.So yeah , solutions?Mods that add more docking ports for RO?A cfg to add more different sized docking ports of the same type?I don't want to modify a pre existing docking port , since I'm already using them on smaller ships and I fear to break them by doing that.Thanks!

Hi, am i the only who never uses RCS?

What I came to observe is that the Docking Ports (Any size, any make) never behave consistently. Docks sometimes, sometimes doesn't. I have also ensured that the parts have the correct orientation, is controlled from the port, the destination port is targeted and everything else (disabling RCS and SAS just before docking). Didn't work out. I then tried editing the save file from various VERIFIED sources, but all i found was that they were in perfect order. Nothing indicated that the ports had erroneously considered itself docked when it wasn't. So drew a blank there too. I simply can't figure out the pattern of successful or unsuccessful docking. Looks like the ports have a mood of their own. What am I missing?? The game runs smooth as butter, but a huge headache when i have to start docking stuff. If it doesn't dock, start the mission all over again and HOPE to work perfectly. I have come to notice that docking had issues in previous versions, say before year 2015. Very rarely have docking problems been reported in 2016-17, so I assume it's been debugged. So what would be my issue? (I would have attached my quicksave.sfs file, but u cant figure out how.)

I found some really nice and easy ways of docking I wanted to share. Since my time today is limited, I'm not going to finishing this post right away, I'll do further editing of the OP to include more methods. Everyone is welcome to share theirs, if they're better explained than mine or new I'll include them with a reference to the author. 1. My absultely favorite method I can't believe I haven't thought of earlier. Really, I just discovered this method very recently and I hit my forehead onto the table for not thinking of it earlier. Dependencies: (- having completed the rendezvous maneuver successfully (this tutorial is just on docking)) - Torque wheels on both vessels - Control over both vessels (all SAS features on both vessels) - propulsion on one vessel (not necessarily RCS) 1.: get the two vessels close together (less than 100 Meters should be fine) and cancel out relative velocity as precise as possible (0.1 m/s might be too much). To do this, switch to target mode, point retrograde and burn (very gently) until your velocity-indicator reads 0.0 m/s. If you're not close enough to your target, get closer first. 2. tell SAS to point towards the target. Make sure RCS is disabled while the ship turns to prevent any change in relative velocity. It needs to stay zero. 3. switch to the other vessel using the "/" button. 4. repeat step 2 with the other vessel. 5. Throttle up very gently on any of the two vessels until you move towards the target at 0,5 to 1 m/s. If your relative velocity was zeroed out sufficiently and the distance between them wasn't too big, they will dock. this method works surprisingly well, even with very big and sluggish vehicles.

I am trying to build a rover with the docking method, only i can't get these two to dock even though the docking ports are right on top of each other. Is this a bug or am i doing something wrong?

Hello all, Whenever I try to separate the CSM from the 3rd stage, the four fairing pieces that come with the rocket do not detach. I know that I have my staging correct. Does anyone have any helpful tips? Any help is appreciated. mustangpilot51

So I've a question for some of the more nuanced players who swear by Vernor Engines over the RCS thruster blocks. I personally typically use them as secondary controls during very heavy launches to keep things aimed where I want them, and after that I ignore them. For those of you who typically only use Vernors, how do you place your engines for front/back translation during docking maneuvers? Assuming your docking port isn't on your nose, as mine is typically strapped to the side somewhere, it's not simply a matter of using your engines as you need to brake in fine increments as you line up, so without some very unique attachments (like strapping some I-Beams on at awkward angles), I'm wondering how it's done? Words are good, pictures would be awesome! Thanks in advance.

I have been trying to dock this for 45 minutes, I just realized that the hatch is closed, on both sides none the less. But there is no option to open them. What have I done wrong?
