Maneuver node for interplanetary transfer not working as expected
I set up a maneuver node for transfer from a solar orbit (adjecent to Droo's orbit) to Cylero, the projected trajectory indicates intercept of the vehicle with Cylero. After executing the maneuver the vehicle is well short of Cylero.
I have no trouble getting from Droo to Luna.
(I played KSP for years so i think i know how it is supposed to work)

Btw, is there a way to move/slide a maneuver node along the orbit that it is on, in order to optimize it (instead of canceling and retrying in case the timing of the node is wrong/inefficient) ?

It's a little buggy, you have to burn manually for the most part but you can use the nodes to plan when.

You can move a node by opening another one, then the previous one closes as a dot on your orbit line and can be dragged. It is buggy as well though as your burn is preserved in absolute direction. So 90deg on your orbit, your burn changes from prograde to radial out. Not very usefull at the moment.

I really hope they do a better job than KSP at these nodes. Some precise control over burn amount and the ability to plan nodes far in the future. Snap to peri/apo/asc/desc nodes is also useful.

I'm assuming you did a manual burn (there are issues with the auto-burn stopping early).

So, you setup the burn node, which projected an intercept, and executed it. Immediately after executing the burn, it no-longer predicted an intercept? Did you try to warp there anyway to see if there was an intercept, and it just wasn't being predicted properly?

FYI: I'm doing a lot of work on these issues right now, and can hopefully get things working better in the near future.

Thank you, I'm glad I wasn't just going crazy with the auto-burn never getting me all the way there. Happy to hear that it's being worked on!

Yes i did the burn manually. During the burn the node moved retrograde along the new orbit. Figuring it had served its purpose i deleted the node. At the end of the burn the predicted closest approach was well behind the target. Then i used time acceleration, the vessel ended up at that point.

Is there a way to have the burn nodes trigger? Every time I do it, the craft will reach the point, then fly right past it. Is it only a guide to help you figure out what to do?
