so, this is the first time I am actually trying to reach duna with far and deadly reentry in carer mode.
this is how I intend to land there:
going down, the fins should stabilize descent while heat shields should protect science equipment.
drogue chutes open and the shield detaches, then the radial engines are enabled for powered landing.
at liftoff, the fins are detached, so tail becomes a pointy nose and the science equipment dropped to reveal a fifth engine.
will test a while in kerbin atmosphere then see how it goes. godspeed, Jedidiah.
update:
everything failed. mission to duna was successful.
I also sent a shipment with supplies and everything, so now jeb is back with bob and bill.
it is now year 2, day 152. I have 365 day of supplies, 3.4k dv, and no solution to get back home; the first window is in 500 days or so.
this is the only transfer solution that could make it. only ejection cost is shown; it assume a perfect burn straight into kerbin atmosphere .

and it relies 100% on aerobraking for capturing... which at that speed is next to impossible as orbit passes quite close to the sun, arriving at kerbin at an odd angle (odd angle = more dv between me and kerbin)
so I will have to mount a super fast shuttle to go and intercept the craft, slow it and drop it in the atmosphere at a reasonable speed.
