Hello, KSP forums.
I'm launching my first Joolian probe, but I don't think I can get a reasonable amount of delta-V without going overboard. So of course, I chose using a gravity assist to propel my probe to Jool. However, I probably won't be able to 'wing' the gravity assists without the transit time becoming impractically huge. Is there a program that can plot out gravity assist maneuvers and perhaps plug them into MechJeb? (I don't trust myself to execute the maneuver properly)
