Interplanetary

[Matt77]

Hello

My space program has recently gone interplanetary having "mastered" the Kerbin system with stations, rovers and manned flights just about everywhere. Currently a slightly flawed Duna mission is arriving at the red planet and a few probes are in LKO awaiting their transfer windows.

The Kerbal Alarm Clock is saying the windows are different to what Protractor thinks, by quite a large margin

Which one should I trust?

When KAC goes off, make a maneuver node and see if you get an efficient encounter. Same with protractor.

Otherwise, trust Protractor.

Ok, thanks. They actually disagree by a day or more at the mo, but I'm not sure if that's significant in the grand scheme of things...
