MechJeb to another planet?


SpaceLaunchSystem

Recommended Posts

I know it's possible to use MechJeb to transfer to another planet, and it was on a Scott Manley video a while back, but I just don't seem to remember how. I've been putting satellites in LKO, and I've been to the Mun, but now I'm ready to attempt a landing on Duna. Can anyone give me a tutorial on getting to other planets with MechJeb?

EDIT: Correct me if i'm wrong, but I believe it was something along the lines of this:

1. Use ascent guidance to place ship in a 500km (approximately circular) orbit.

2. Use "transfer to another planet" under Maneuver Planner to create and execute a transfer burn.

3. Select "fine tune closest approach to target" under Maneuver Planner and create and execute node.

4. Once ship is intercepted into the planet's SOI, create and execute a "circularize" node.

Pretty much that, not much to add.

1) Initial starting Kerbin orbit altitude not particularly important, lower altitude nets you more oberth effect unless your TWR is too low to complete the ejection burn in time. - experiment :)

2) Something like KAC or Protractor will help to time the launch so you don't need to loiter in orbit waiting for a transfer window. MJ "Advanced transfer to another planet" will let you pick a time vs. DV trade that suits you.

2b) MJ can get a bit jittery if you plan a transfer while too far (>1year or so) away from the window.

4) I usually adjust my periapsis soon after entering the target SOI & before circularising.

If you're game, aerobraking at Duna can save considerable DV :)
