I ended up ragequitting the polar Kerbol contract. My final rocket stage was just a big tank of fuel on four nukes. A Mun+Duna slingshot kicked up my orbit, close to the plane of the target orbit even, but not nearly as much as I hoped. I needed an hour-long 4k burn after that and haha, nope.

I ended up making a million exploring the moons around Jool and practiced aerobraking. Aerobraking is a lot of fun, when it works!

Depending on the number of parts and physical size of your craft, you can use physical time acceleration to take that down to a quarter.

If you're going to do it efficiently, this is another jobn for the bi-elliptic transfer.

Wait until Kerbin is crossing the plane of the target orbit.

Ser up a burn that has you leaving Kerbin's SOI along its direction of travel with a very, very distant solar Apoapsis.

Coast out to wherever that solar orbit crosses the plane of the target orbit. Do your plane change there, when you're moving /really/ slow. Also raise your periapse to touch the target orbit, then come back in and match the target orbit.

You'd save quite a bit of delta-V doing that (I'd estimate that the low limit would be on the order of 5-6km/s from LKO. On the other hand, it takes a /heck/ of a lot of time on the bi-elliptic transfer to push the costs down that low.

This post is where it is at.

I found a welding mod for combining things into single parts in the VAB, but is there one that lets you do it to something already in orbit?

For a spaceplane, is it a good idea to have the center of lift slightly forward of the center of mass so it tends to nose up? It's a bit of a pain in the rear end to keep it headed upwards when the center of lift is behind. It flies fairly stably but I want it going up, not straight.

No, you want the mass sliiightly in front of the lift. This is so when it starts to stall you gently tip forward, rather than doing backflips.

What you need is more control surfaces.

Or RCS/SAS

It seems to work okay, has a nice stable climb. However I just had my RAPIER engines switch to rocket automatically, as they should. But then the ones on the left side switched back to air breathing by themselves and flamed out and the inevitable occurred. :argh:

I can get to orbit pretty reliably with a spaceplane now, but it burns up basically all my fuel. They seem so inefficient compared to rockets, I'm not sure I see the point. I must be screwing something up.

And that's why we don't have spaceplanes and the SLS is a rocket.


With aero revamp, they'll save you some fuel, but you'll still be limited in your payloads. Their real benefit is for stuff like LKO small satellite release, kerbonaut ferrying, and maybe refuelling---so you do your thing, then bring back the ship for 97-100% recovery and the only expenditure is fuel. Of course, if you're swimming in funds or in sandbox there really isn't any point outside of looking cool.

That's what I was thinking after I posted that, am I bad at spaceplanes or is this just an accurate simulation of being cool but pointless? :v:

I'm just working on a cooler ship for taking crew to/from my space station, I wasn't planning to do much with it. But I can't get to orbit with enough fuel to get to the space station unless I send over my orbital tanker to refuel it, which is just making the whole thing pointless.

Groetgaffel smacked the living shit out of himself doing 297 points of damage.
We also don't have any functional SABRE (or RAPIER as KSP calls it) engines yet. Without those any real life space plane is essentially just a rocket with wings anyway.
If the Skylon ever works out as intended it's going to cut launch costs per kilo payload by about 23(!) times.

E: I made a little tiny plane that is absurdly fun to fly with NEAR.



It's all stock except for the TweakScale'd circular intake and whatever mod the curved solar panel comes from. (Near Future Solar I think)
It managed 1300 m/s at an altitude <1000 meters, and pointing the nose 45 degrees up with full throttle right from take-off put it at an apoapsis of 90 kilometers. Again, in NEAR. No idea how it handles in the stock atmosphere.

I strongly recommend a canard setup if you're having trouble with pitch authority. That also lets you put your wings far back to help with getting your CoM ahead of your Col (since the engines tend to be the heaviest part on a space plane)

Hey Max or RoverDude, quick question- will the resource parts be in a separate tab so they don't clog up the Utility tab? That tab in itself is pretty cramped and unorganized already, adding more parts might make it even worse.

You can make your own tabs already, BUT to display and select them you need to keep the full advanced filter interface open. Which is really annoying and only increases confusion.

If you're careful with your encounters you can save deltaV and time by using Jool to kick up your inclination with a well placed encounter, add a burn at perijool and you'll maximize the oberth effect for profit.

Given infinite time you can go out to near infinity and use less fuel, but the Jool encounter will make the whole thing a lot faster.
