My procedure is standard:
- Launch and start pointing East
- Be on a 45 deg angle eastward by the time you reach 10 km
- Cut engines at desired apoapsis
- Create maneuver node at apoapsis
This is where it goes wrong -- when I drag the prograde marker to circularize I can never get a circular orbit. I have watched countless videos and have been doing this for a while but I always get an elliptical orbit, no matter how finely I tune the prograde/retrograde markers. Am I missing anything?
Hey guys ! How can i make this selected area circular ? I mean only the faces. I've been using maya for couple of months before switching to blender and i could do this operation with circularize component method that maya includes. You can check it out for for better understanding if you couldn't understand my question very well.
Maya Example;
Thanks! Have a good day.

I’ve heard to always circularize an orbit when going to anything that’s not kerbin. I noticed a pattern to get to the mun without having to circularize. Would going straight to the mun be better than circularizing?
I got into Eve orbit with a very high apoapsis, did one complete orbit and then could have a gilly encounter. I did a correction burn mid-way to get into the light side of Gilly and when I try to circularize the manuver node maker says it tooks 2.000 delta-V and if I burn retrogade in Gilly's apoapsis nothing would happen... (I am using nuclear engines btw)
EDIT: I finally did it after tips from every single one of you guys I got into a good orbit on Eve and mannage to get an encounter with Gilly, I landed, got into an Eve Orbit and now I am trying to get an encounter with Kerbin
EDIT 2:You guys are legends love this community
I have a probe with about 500 m/s surfing around the Jovian system, with an apoapsis just above Callisto's orbit (after a dozen flybys already), and a periapsis a few thousand km above Jupiter's atmosphere. I have two options: give it the Galileo fate of Jupiter's atmosphere or the JUICE fate of trying to wrangle it into an elliptical orbit around one of the Galilean Moons. I've been trying the second option, without much luck, and I've tried searching for JUICE's trajectory around Jupiter, but haven't found much useful stuff. Is there anything you all may know about these kinds of maneuvers?
Hello,
Im struggling with understanding how to efficiently circularize around Kerbin. At launch I get my apo to 60-100k. But when I create a maneuver, sometimes the burn time is 3 mins long, othertimes 1 min. Obviously, the less fuel to burn the better but Im honestly not sure how to achieve that shorter time. Does it have to do with my relation to apo as I am ascending? Do I need to flatten the trajectory a little?
So I started playing jsnq a few days ago and when I sent a probe to duna it took about 2000 m/s of delta v to circularize even though the delta v maps says it take 910-1155 m/s so why is it almost double?

Burning prograde at apoapsis will increase the height of periapsis without changing the height of apoapsis (also works in reverse with burning prograde at periapsis will increase the height of apoapsis)
Use this to circularize an orbit by burning prograde at periapsis to bring down your elliptical orbit down to periapsis, or you can burn prograde at apoapsis to make your orbit as high as apoapsis. also works in reverse with retrograde burns.
I’m a noob! But I just spent an hour learning to circularize in LKO and then safely deorbiting to land at a spot of my choosing! I feel very accomplished.
Before I explain my situation, allow me to explain what I do know.
The first time I tried to go to the Joolian moons (Laythe) about two years ago what I did was get a direct Laythe encounter while I was still in Kerbin, then I tried to circularize from my periapsis. I learned my lesson that I was coming in too hot/too fast and I needed to have a stable orbit around the parent planet first. This is when I learned about gravity assists. Throughout the next two years I rarely played KSP and when I do I just build Minmus bases.
Fast forward to this year, when I to to the other gas giants (OPM), I am aware that to get to a circularized orbit in the gas giant I have to pass in front one of their largest moons. From there I just have to get an encounter with the moon I want to go to and circularize from there. That's what I've been doing for the OPM gas giants.
It's been a while since I went to Jool. This time I wanted to go to Vall (my favorite moon btw) to land a rover. I did my usual routine, from Kerbin I got a Joolian orbit, when I encountered Jool I adjust my orbit to get a Tylo encounter and made sure I pass in front to lose speed, then eventually I end up with an elliptic jool orbit. Now I just need to get an encounter with Vall and circularize and land.
Now, here's my problem. When I got my Vall encounter, I tried to circularize but I needed about 4000dV. That's weird, because I am already in an elliptical Jool orbit and I shouldn't need too much dV to land anymore right? What I then tried to do was get multiple Tylo passes in order for me to lose more speed and keep lowering my Jool orbit. However this doesn't seem to work. I either keep getting a larger orbit and/or sometimes a more tilted one. I remember the last time I went to Jool I successfully landed a rover on Vall using the Tylo technique. But I can't seem to do it anymore. Any help would be appreciated. Thanks!
Is it more fuel efficient to slow down at a high altitude or as close to eve as possible (just above the atmosphere)? Im asking because im planning on then making a manouver to encounger gilly, because i cant seem to get an encounter heading straight to gilly.
Is it easier to circularize around a moon or planet without an atmosphere from a higher or lower orbit? Got an intercept with Moho now, wondering where it is best to try to circularize. Thanks.
Basically, are celestial bodies fixed on their courses? If I were to land a mining/refinery rig on Gilly with an engine facing up, could i eventually circularize it's orbit around Eve, given enough time?
I know the radiation pressure is apposite the force of gravity at all parts of the orbit. Since radiation pressure falls off with the 4th power of distance and gravity the 2nd power, I would imagine the radiation pressure would be greatest at the aphelion and slowly over time push the aphelion away from the sun.

I've finally achieved a somewhat intuitive idea of how the peri- and apoapsis is raised/lowered by burning prograde and retrograde.
However, I don't have an intuitive grasp of how burning radial in or out works. If you look at a diagram, it would seem that burning radial-in when you are at periapsis, you would lower your apoapsis. It seems like it would shift your whole orbit. Is that right? Are there other ways that you can circularize?
Other than to possibly have more of an accurate landing site, is there a reason to circularize. Does having a highly elliptical orbit increase the entry/periapsis speed? Thanks for any help, and Merry Christmas!
Fuel Efficiency-wise... Should I be circularizing at 100km and then change your orbit to 650 (for max warp speed), or make my apoapsis 650 right from launch and circularize there?
I was hoping to find a really simple way to circularize my orbit when I hit my desired altitude from launch, without having to do complex math or create nodes. Nothing I have attempted to do has worked very well. Things I've tried include "until apo < peri + 1000 {burn prograde or burn heading(x,0)}"
EDIT: Here is my code (for a spaceplane, I also have some code for rockets which is a bit different) http://pastebin.com/deF0QBJP
