Any word on doing the opposite, transferring evenly from one source to multiple destinations?

The boosters on the lower stage are not attached to the decoupler, they're attached to the tank with the decoupler clipping through them.

I don't have any evidence at hand since I'm at work currently, but I did test and confirm it myself.

I recently found out that this is no longer the case, and all 4 connections can connect on both ends.

Take off, fly out a bit, turn around, quicksave. Then quickload and land as many times as you want.

More action groups.

I consider it cheating to do something like put hidden wings inside the body of a plane, but not to do something like put a cubic strut partially inside something as an attachment point.

Maybe use the landing gear to lower the lander down to the rover? Like, have two sets of gear at different heights. Land, drive the rover into position underneath, then retract the first set of landing gear to lower it onto the other set. I've put maybe 30 seconds of thought into this so no guarantees that it will work well, but I'm going to try it when I get home from work.

I'd like some sort of fuel tank ordering system. Maybe give each tank a priority, and the highest are used first, then the second highest, and so on. And make tanks of different size but the same priority drain proportionally, so they run out at the same time.

Drogue chutes...

Just FYI, with that tri-sci module you've built, whichever 3-way adapter you added second will only be connected to one of the science modules. Won't make much difference in that ship, but if you ever connect that top docking port to anything, it may be a bit more flexible than you expected...

No, that's not right. You're thinking of autorotation, and it's not to spread impact forces, it's to land safely without engines.

They list each individual part in the craft file, and if I remember right, each has a field listing the other's it's symmetrical with.

Tried to land a spaceplane on Eve. Landing wasn't too hard, but I realized on the way down, when I tried to start the engines, that taking off again might be problematic...

It's absolutely possible. What parts were in the probes? They need to have a "control" part like a probe core, and probably batteries and/or solar panels or they'll just be useless debris once they detach.

Or are you in sandbox mode?

The way you describe building it, only one of the decouplers will actually be connected on each stack. The game engine won't allow what you're attempting. Two options: 1) Get rid of two of the decouplers, add struts for strength. The struts will disappear when you decouple, but they will also eliminate the decoupling force so you may want to add seperatrons to push the stack away when it decouples. 2) Add the side tanks individually, attached to the decouplers instead of the tanks above/below, and then connect them with fuel lines.

One thing that comes to mind is that the atmosphere in ksp moves along with the surface, so as you go up, it is probably adding some additional eastward velocity due to drag.

Are you sure about that? Keep in mind that the path drawn on the map doesn't show where the planet will have rotated to by the time you land.

What kind of decoupler? If you mean a radial decoupler, that can't work, the tank can only be connected to the decoupler OR the other tank, not both. A stack of tanks will need to be attached with a single decoupler, then struts if you need to strengthen the connection (the struts will disappear when the decoupler is activated).

It sounds like when you attach the replacement tank, you're attaching it to the tank next to it instead of the tank below/above it. Play close attention when you reattach it, you should be able to see where it's connecting before you click. Try changing the camera angle so the tank next to it is not behind the mouse pointer when you're trying to position it.

I wrote a perl script that removes parts and renumbers the rest. It's not really ready for the general public and I haven't tested it with .23 yet though. If you want to post your persistent.sfs file and let me know what part to remove, I can try.

No, you lost delta-v because you added payload. The thrust and energy did not change, you just need more energy to get the same d-v out of a heavier payload.

I looked up last night and saw Jool was quite close to the Mun.

Flew the X-Wing to orbit, refueled at my station, docked with its interplanetary stage, and Landed on Laythe. And forgot to take screenshots except one at takeoff. Hopefully have enough fuel left to get Bill home later...
