What is going on with minmus' gravity?

Recommended Posts

I am doing an Elcano on Minmus currently, but I am experiencing something strange. My rover sometimes starts losing speed on seemingly downhill slopes. And if i accelerate while on 4x physics warp, after a while I also start losing speed. Additionally, the navball though t I was in orbit while going 2.1 m/s? Is this just a bug due to Minmus' small size/low gravity?

Well, you can click on the Navball to get it back into Surface mode.

As far as slowing down, my first ask would be what settings you have on your wheels.  We all know that wheels and physics sometimes don't mesh well in this game, and they can seriously mess with your mind.  Possibly too much or not enough traction, which would then cause you to stop rolling?  I'm just spit-balling here, but it couldn't hurt to at least take a look.

Yes, I knew this, just weird that it switched is all.

I looked, and it seems that too much traction makes me slow down, and too little makes me speed up. Thanks!

You are welcome.  There are so many different options and settings and tweakables that it is impossible to remember everything.  I simply made a guess based on the number of threads that are out here complaining about wheels.  But I am glad that I was able to help, and you are most welcome!  Happy flying!

The speed loss could also be because you seem to be driving west (orbital direction) on an equatorial route (about 30° N) at a high altitude (orbital navball).  As you speed up, you negate more of your orbital speed so the NavBall reads a lower value.  Just click it to switch to surface speed.

No, I was slowing down to quicksave, going around 2m/s surface speed. Then,  the navball  switched to orbit mode.

The gravity there is low enough that I'm surprised you can get any sort of traction at all. Most likely, all your issues are due to the gravity there. Your wheels don't grip the surface properly and all sorts of weird things can happen at 4x physics warp.

This changes because of your sea-level height is large, thus thinking you are flying. I dunno why.

I had this a while ago, when landing on Minmus.
