![]() ![]() The reason that's confusing at first is that there isn't any warning that the meaning of the marker changed other than the rather cryptic fact that the text changes from "Orbit" to "Target" in the navball's title box. (In other words if your target it going 2300 m/s and you're travelling the exact same direction at 2314 m/s, it shows a velocity of 14 m/s - your velocity relative to the target, and also the retrograde marker (green) is showing you a direction that is NOT necessarily retrograde to your orbit but rather is the direction to burn to reduce your relative velocity to the target from 14 m/s down to 0 m/s.) You can imagine my confusion when I was being told that to match velocity with my target I need to "burn retrograde until velocity is zero" and I still thought the navball marker was showing my orbital retrograde mark so it sounded like I was being told to slow down to a complete stop so I'd fall straiight down to the planet. That brings up an important point that confused the heck out of me when I watched videos explaining docking because the following important fact was not mentioned to me: When the navball says "Target" at the top instead of "Surface" or "Orbit", that's telling you that the meaning of the prograde and retrograde marks has in fact changed and they no longer show you your movement relative to the planet you're orbiting, but rather they show it relative to the target. ![]() But they are not the prograde or retrograde markers relative to the target, which are still the yellow and green marks like always. The pink markers show you if your craft is *pointed* at the target (or 180 away from it). The way you phrased it here could confuse people. You use that for docking, when you want to close the last couple hundred meters It's important to note that there are seprate prograde and retrograde markers when docking that are in fact different from the pink markers.
