Why does my lander stay in "surface movement" mode?

[jwatte]

I built a booster rocket and a lander, and go a pair of Kerbals to walk around on the Mun.

Then I re-entered the compartment, and dusted off upwards again.

However, I never got the trajectory displays again, and whenever I wanted to switch to space center or otherwise manage the flight, I got the message that I was "moving on the surface" and thus must stay in the mode I was.

I was actually > 50000 meters above the surface, on a ballistic trajectory upwards.

Is there some mode or key I need to hit while on the surface, before taking off, to go back into "trajectory/orbit" mode instead of surface movement mode?

Or, if not, what else could have gone wrong here? I want to bring those Kerbals back!

If you want to manually toggle between different modes, you can click on the velocity indicator to do so.

You're right that it should automatically toggle once you've reached sufficient velocity to establish an orbit, unless you had manually toggled it by accident once before. When you say that you were on a "ballistic trajectory," was it still only suborbital (i.e. did it form a full orbit, or did it still intersect the ground somewhere)?

While what Specialist290 says is technically true, I don't think that this is the problem. If I'm reading jwatte's post correctly, he's in orbit around the Mun, but the game thinks that the ship is still landed. I found someone with a similar problem here, which offers a possible fix.
