[Minmus] Fail to land due to Minmus rotation

[goshiz]

Hi Everyone, I've spend most of my day trying to land near the Monument of Minmus but fail to do so... 

Everytime I try to land using retrograde booster and/or anti-target (for the the final approach) I still have a relative velocity to the ground that make my ship to fall over and land on the side. I search accross google and did'nt find anything interesting, a lot of topic saying it's easier than the Mun (where I can land pretty easily...) so I don't get why I fail to land on Minmus.

Hello @goshiz, and welcome to the KSP Forums!

I do have a couple of suggestions.

I recommend that your NavBall be in Surface mode.  In KSP2, in surface mode half the navball is brown/orange, and the other half is sky-blue.

When landing, you obviously want lateral (sideways) motion to be zero.  One technique to do that is with your navball in Surface Mode:

• Descend to 10 - 50 m above the ground- Just above the ground.
• Stop your descent completely, so that the velocity reads zero.  You will be essentially hovering over your landing site.
• Once you have a velocity of zero, begin a descent straight down.  If you are careful about your thrust direction, you should not pick up very much lateral motion in the last few meters of your descent.
• At touchdown, try to have your velocity at or below 1.0 m/s.  Most parts can handle an impact of up to 6 m/s, but the faster you go the greater the odds of tipping over.

Try to choose a flat landing surface.  Also, wide landers are more stable than really tall skinny landers.

Good luck!  Most likely you will succeed very quickly.

dont go anti-target.

go retrograde of surface.

 

Older KSP didn't allow targeting body when you were in its influence. In ksp2 when you enter orbit of Minmus, you should unselect target to make sure you wont use it as an reference.

Did you find a fix to this bug? This happened to me as well. Seems hard to describe because other people aren't understanding what you are meaning. 

When we are landing the moon (minmus) still spins.. This is making us have a sideways velocity. That makes it impossible to navigate with the navball/SAS, If we tried to land with this bug we would have to have a velocity equal to the spin of minmus in the same direction. That would be ridiculous to try and do.  I just took 200t of rocket up to minmus and discovered this for the first time. EXTREMELY frustrating... Seems the game still thinks you are in orbit and changing navball doesnt work either.

On the left of the navball, it likely says "orbit" and some velocity.

Click that part of the screen, and it will say "surface" and some velocity.

If you then aim retrograde and slow down, you'll descend far closer to how you expect. If you slow down to 0, you'll be hovering over the ground (and then start to fall straight down).

Could you post a set of screen shots where you are in SURFACE mode with almost 0 velocity, yet the screen shots are showing you obviously moving across the surface at a significant velocity?

If so, that may be enough for a bug report, especially if you can quicksave and quickload, and still be in that situation.
