Make a ship that can transport a Kerbal to Duna. However, there is a catch, you can only use 10 parts in your rocket. Parts are anything you attach to your rocket, there are no exclusions (that means that you can find out how many parts are used in the load menu in the VAB). The only requirement is that you get the Kerbal on to the surface of Duna and can plant a flag, there need not be a working craft on the surface, an example of where this might happen is a mass-relay. You can use any means of getting there, such as ion engines and the EVA pack. The winner is the first person to complete this in out-of-game time.
