How to intercept comet


Question

Posted (edited)

I tried Rosetta mission from the new ESA mission pack. I tried to plot it's course using Duna(mars) as gravity  assist but forget how to do it :-(

The Rosetta mission is much simpler if you just do a direct transfer and try to meet up at or near the comet’s apoapsis. As long as you get close (within about 500,000km) you can match velocities and then intercept as it drops back towards periapsis, which also means the tail will appear and make it easier to see when it drops inside Duna’s orbit.

If you want to go to Duna for any purpose, including a gravity assist, then you need a transfer window.  Your Kerbin-Duna configuration right now is terrible.

Either use Mechjeb's Maneuver Planner> Advanced transfer to another planet function (just target your intended planet and tell it to create a maneuver node) or install Astrogator, both will identify launch windows and plot exact courses for you. I think Mechjeb is a bit more accurate for transfers, but Astrogator has a window that lists off all the upcoming transfer windows in one place, making it easy to figure out what missions you have to launch and in what order, so the compliment each other.
