Starting to loose hope that i'll ever get my Kerbals to Duna...

[SpaceLaunchSystem]

Whenever I build a manned Duna spacecraft, I inexplicably discard it immediately after building it. They usually have enough Delta-V to land (and return!) without help from aerobraking. I use MechJeb, so i'm also probably going to need a tutorial for getting there using it. I'll probably post a separate thread for that.

I'm not sure we can help you with that. Have you tried replacing your legislature?

[Signo]

Just go for it. Duna is one of the most wonderful places around.

I'll echo Signo here. Go for it. If your design deltaV adds up. You will have fun and learn whatever

[Bill Phil]

Go for it without MechJeb first. Getting there on your own is so satisfying... And build probes first. They're generally small and so they use smaller launchers.

(my bolding)

You might need the help of a psychologist or a philosopher ...

Did you have a topic or question for the rest of us?

[SRV Ron]

Go with probes. This very cheap one, one on the left, made it with fuel to spare.

Note, in KSP 0.90 Beta, use the Probododyne OKTO in place of the Stayputnik.

This one is better.

Duna is evil. Duna will rip your dreams to shreds and scatter them in flames over it's surface. Go somewhere else.

Moving this to Gameplay Questions

The important things to pay attention to (after available delta-v, of course) are launch windows and phase angles. As a general rule of thumb, for the most efficient transfers, you want to plot the burn so that your outgoing flight's path is roughly parallel or tangential to Kerbin's own orbit.

While this tutorial is a bit older, the basics should still be perfectly valid for the current version of the game as well.

Once you get the idea of transfer windows down, send a few missions at once (well, within a few days of each other). With Ike in orbit, it can lead to some interesting missions.
