Nodes of maneuvers cant appears

[Swap]

 

I just bought KSP yesterday, and I can not create nodes of maneuvers, my apoapsis points should be blue except that they are gray, so I can not create a node by clicking.

Can someone help me?

Hi, @Swap, and welcome aboard!

 

I'm gonna guess you're playing on Career mode. You'll need to upgrade the Tracking Station before you can make maneuver nodes. Hope this helps!

Also need to upgrade Mission control.

Just to build on the answers provided by @Dman979 and @Spricigo above:

• When you upgrade the Tracking Station, then the trajectories will be shown in blue instead of gray, and you'll have more information about them in map view.  But you won't be able to create maneuver nodes yet.
• When you also upgrade Mission Control, then you'll have maneuver nodes.

If you try a sandbox game (as opposed to career), everything's all fully-upgraded for you when the game starts, so in sandbox you have maneuver nodes available from the very start.  But in a career game, you need to upgrade the buildings.
