Need advice for my Duna Colony

[Jaedinator]

Hello, I decided to build a colony on Duna, but i could need some help.

1. Is it possible to send several modules to Duna on the same transfer Window? Could I be able to control them properly throughout the flight when i launch like 5 modules in a row with ~1 Hour between them?

2. How to chute-land them all on the same spot? (I wont use mechjeb) Landing several crafts on the mun on the same location is fairly easy because i can just kill my horizontal velocity at the same spot every time. But due to Atmospheric drag and the fact that duna is too big to kill horizontal velocity above the atmosphere(too much dV needed), how do i aim parachute landings properly?

3. How do you match the height of rovers and fuel modules so that you can refuel them easily?

I hope you can give me some advice Thank you and have fun

you should be just fine sending multiple missions over the same launch window, there's some give to it, and you can easily send out vessels even a couple of kerbin-days apart without sacrificing much on dV requirements....

still, perhaps more efficient would be to just dock multiple vessels, then send them all together under the same engine (nuclear, at best) -- remember, once you're in orbit, there's no need to accelerate all that fast - so you'll get a more efficient ride out of assembling a larger vessel in a more homely orbit beforehand

plus, then you won't need to juggle between a barrage of assorted vessels - you reduce your "kerbal error" risks by a drastic amount this way

remember Murphy - it's the law!

I sent this to Duna (Vessel to right attached to my orbital station). with 4 Home modules attached and landed them simultaneously

Here they are landed on Duna. I had to move them closer using the DEMV crane in the foreground as they landed 100m apart

Your idea is great, i could just put everything together on the sides of a large truss, the only thing i will need is to pack 2 or 4 of everything, what shouldnt be too bad. And landing could work pretty well too, just decouple them on suborbital trajectory with chutes on. Thanks to you
