Timewarp is one of the biggest reasons you can't do multiplayer. Everybody would want to be on a different time scale, so everybody would have to be at 1:1 and bored most of the time.

I revert if things don't go as planned in any way. The first run-through is now a "computer simulation".

And warm! I did it with a xenon powered probe, and one of the solar panels blew up from overheating.

The difference between time warp and physics warp is that time warp only simulates the position of your entire craft, and only checks for gravity and intersection with planets. It's very simple to compute, which is why it goes up to 100,000x. Physics warp simulates everything, including intersection with every part with the surface, battery charge, thrust, fuel levels, etc. So it's much more processor intensive, which is why it only goes up to 4x. Even then, it takes shortcuts that can make mistakes and cause things to blow up that wouldn't at 1x. There's one exception to time warp- mining operations. IF you go on time warp more than 6 hours, it calculates mining. I think it takes some shortcuts on that, but if you stop timewarp before 6 hours, it resets and you don't get any mining results.

Yes. You can dock without RCS that way, by switching back and forth to line up the docking ports on both ships, then give a light thrust on one of them to get them together.

Anything can explode in Unity, especially during "physics easing". I've had flags explode when coming out of time warp!

That seems right to me- if you're burning, you're going to be slowing down, so it will take longer to get to the ground than if you were just going to let it go. EDIT- oh you mean the time to START the suicide burn? Yeah, that would be a problem.

Does "Set Root" work?

Because it's there?

Think about it. Imagine you could launch it straight up instantaneously to keosynchronous orbit. 2 hours later, launch the next one- the first one is still straight up, since it's in keosynchronous orbit, so the second one ends up in the same spot. Then do it with the 3rd- you end up with 3 satellites in the same spot. Same thing will happen if you use a normal transfer orbit to get it there, it's just harder to visualize.

I've done it that way, but MechJeb has "Advanced Interplanetary Planner" which has the same porkchop display. You click somewhere, and it creates your node.

Elon Musk would agree with you. MOAR BOOSTERS

You also won't see autostrut options unless you have "advanced tweakables" turned on in the settings. If you don't have that turned on, it's probably not the problem because you aren't using autostruts. Another possibility is reaction wheels in multiple modules fighting with each other if you have SAS turned on. Quickest way to fix that is to turn SAS off. If you need SAS on, turn the reaction wheels off in every module except one. You can do that without advanced tweakables.

Go more places. Each place you go only counts once. Basically, plant a flag on mun and minmus, anybody in physics range gets credit so you only have to do it with one kerbal per vessel. And then leave Kerbins SOI and come back, that will get those Kerbals to 3 stars. To get any further you have to go to other planets. https://wiki.kerbalspaceprogram.com/wiki/Experience

Fastest I've gone is maybe 180 in a Decathlon diving before a loop.
