Ok, so I like playing in the order of Orbiter > Lander > Rover > Kerbal for most planet missions in KSP. I've already got my orbiter, Explorer I, in a low polar Duna orbit. The next step is putting a lander there. I wanted to design something like the Phoenix lander. But I'm not entirely sure how to do this. I need to make sure I have enough fuel to land safely, but also not make it so the engine touches the ground and the landing skids don't. I could use external fuel tanks, but the lander's mostly packed with science, solar panels and batteries. One of my ideas was to land with the help of Puff Monoprop. engines, but I don't know if it'll be enough to land.
This is what the lander looks like (ofc everything will be retracted on launch)
So I'm not certain where I'd put fuel tanks or monoprop. tanks and whatnot to make it all land. One idea was a skycrane but I haven't ever tried to do that yet.
So, anyone who's better at this game than me, what might I be able to do to get this thing landed and if there's anything I should add, let me know please. Thanks
