The Maneuver Node Editor provides a text-based interface for editing maneuver nodes. It can be useful for fine-tuning maneuver nodes when it is difficult to drag around the maneuver gizmo gently enough.

A maneuver node has two properties: a time and a burn vector. The Maneuver Node Editor lets you alter both.

Editing the burn vector

The burn vector specifies how much and in what direction to burn. The burn vector is given in terms of its components in three directions:

  • Prograde (forward)
  • Radial+ (perpendicular to prograde, pointing outward from the planet)
  • Normal+ (perpendicular to the other two).

You can enter values for the prograde, radial+, and normal+ components of the burn and click "Update" to change the burn vector.

Often what you really want to do is make small changes to the burn vector to fine tune the planned burn. The right-hand column of the editor allows this. You can enter a small increment for either prograde, radial+, or normal+ and click the corresponding "Add" button to add the given increment to that component of the burn vector. For example, to increase the prograde component by 1 m/s, enter "1" in the top right text box and click the "Add" just to the left of that text box. If you instead want to decrease the prograde component by 1 m/s, enter "-1" instead of "1".

Editing the burn time

To change the scheduled burn time of the maneuver node, enter a time increment in the bottom-most text box and click "Shift time by." To shift the maneuver node to an earlier time you can enter a negative increment. See the "Format for entering times" section of the Maneuver Planner manual page for information about what formats this text box accepts for time increments.

For convenience you can also snap the maneuver node you are editing to the closest

  • periapsis
  • apoapsis
  • ascending node with your target (one of the two points where you pass through your target's orbital plane)
  • descending node with your target (one of the two points where you pass through your target's orbital plane)
  • equatorial ascending node (the point in your orbit where you cross the equator heading north)
  • equatorial descending node (the point in your orbit where you cross the equator heading south)
