[1.0.5] [Delta-V Readouts] [Sandbox] Attempt at a Duna Mission, I don't believe even with KER (Kerbal Engineer Redux), KAC (Kerbal Alarm Clock), and KAX (Kerbal Aircraft Expansions) can give me enough of the readouts required to get to Duna!

[Musicrafter]

Some rough budget estimates off the top of my head:

Ground to Low Kerbin Orbit: 4000 m/s

Transfer burn to Duna: 900 m/s

Duna capture via aerobraking: 0 m/s (thin atmo, go as low as 10km; heat shield optional)   ---   Powered capture: 400 m/s

Low Duna Orbit to Surface: 1300 m/s [parachutes hardly matter, but may save a few m/s]

Surface to Low Duna Orbit: 1300 m/s

Transfer burn to Kerbin: 700 m/s

Kerbin capture via aerobraking: 0 m/s (warranty void if attempted without a heat shield)  ---- Powered capture: 400 m/s

Low Kerbin Orbit to Ground via parachutes: 100 m/s [deorbit burn only]  ---   Powered descent: 2000 m/s

Total minimum: 8300 m/s

Total maximum: 11000 m/s

I'd allot 10 km/s as a safe bet.

A good start point I went for was to just send something there, land it, but don't bring it back. This will allow you to practice a lot of the mission without the pressure of having to return it. I made this craft for a film I made, and it works really well. I think if you go to the thread I link in the description, you can find a guide on how to fly it. If you want more help with the craft, PM me

To be quite honest, I don't plan on returning because of my lander design I have no idea how it would take the Mk1-2 Pod back to Kerbin so yeah...About 12,000m/s is the Dv Objective for me (mabye less if all goes well), I'll be adding the screenshots of my landing stage now. PM Me if you wish to continue helping me

I would like to carry a pre-assembled space station (from LKO) to Duna, with 2 Landers (One for Ike and One Duna), a Crew of 6 (Possibly a crew of 8 because of the Landers becoming manned, whilst the other 6 sustain the station) cause Wynaut, sorry couldn't help myself to the Pokemon Reference), Enough Power for it to stay indefinitly in its Final 25km Duna Orbit, Solar Panels (Duh), Fuel (For Re-Fueling on Interplanetry Missions) and a Return Stage that can get to Kerbin if I'm bored...But of course, it'd be good to start simple and space stations aern't exactly simple...regardless either that or what you've said above would be cool. So here is what I'm planning my mission to look like  (Also it'd be helpful to have some input on weither or not SpaceY is worth installing for a mission like this):

1. Get to Low Kerbin Orbit

2. Assemble the Modules stated above and wait for a Launch Window with Duna

3. Eject for Duna Encounter

4. Arrive at Duna. Do a circularisation burn, till I get a 25km Equatorial Orbit (Give or take 0.1 Degrees)

5. Send the Landers, with enough Dv to return to the station.

6. Wait until I'm bored and return some of the crew to Kerbin to bring up fresh recruits.

 

Of course, I know this will take alot of work and that is why I'm here before the community asking them for help!

Good Luck Guys and Thank you Snark for the delightful response 

If you want to explore Duna in detail, I suggest you to send some refuelling capacity, or at least an upgradable space station you can upgrade later. From Duna, it's very cheap to explore Ike and refuel there.

This can you give you some design example

I would suggest you to assemble your station at target not at LKO, it's easier to do that way (especially for TWR management and wobble avoidance). Send you station there and send a mission with landers and return vehicle. If you refuel there, don't hesitate to burn all your fuel to get there. If you don't refuel there, you can send a third mission with a fuel tank.

Thanks for the help, but do you mind helping me on my current plan (aka. A one-way mission, Lander Images are provided (prey it has enough Dv)

Taking a station to Duna will be FAR harder than dropping boots on the ground and planting a flag and coming home. For the same reason that doing so on Mun is easier.

True, but that's how you progress in the game. I remember after discovering the game and play through Mun and Minmus, I sent a parallel flight mission to Duna/Ike (which was basically a copy of my Mun mission slightly modified). Then I jumped to Jool with a 13 flight space (6 of them were Jumbo fuel tanks) station assembly around Laythe to explore the whole Jool system. I remember preparing the mission for ONE full week, searching after dV maps, designing my 6 different landers, 2 tugs and the return vehicle.

After 1 weeks of preparation, I played 2 weeks until I cam back to Kerbin with more that 40000 science points. That was a very fun mission to do.

I would say to the OP¨, that Sandbox/Hyperedit experimentation if very useful.

Ok, basically, take your last Mun lander, add chutes (2 drogues and 2 to 4 chutes depending on the vehicle mass. I would still suggest to send 2 landers, one for Duna (with chutes) and another for Ike (without chutes). Add a 1800 to 2000m/s interplanetary stage and a 3400 launch stage (in 2 parts 2000 and). 1400m/s)

The Ike Lander should have 600 to 1000m/s

The Duna lander should have 100 to 300m/s for safe landing

As always, lighter is best

The Lander itself is around 17 tons, so yeah...and before I forget to update the post, this is in Sandbox if anyone is wondering! Will plan a mission similar to the Station once I've got the basics down on how to orbit it etc. Will also be installing Precise Node, but its not on the mod list yet so yeah...Thanks for the help @Warzouz but I believe if I get enough budget (as in terms for marginal errors) I'll be good (hopefully xD) so suggestions on what the other stages would look like is much appreciated! Also gimme a name for the ship!

[Warzouz]

@awfulcraftdesigns, BTW, Kerbal-X (stock design) has enough dV to go to Duna and return to orbit. It's an easy ship to fly.

Like originality, so probably not going to do it xD Design ideas using the current lander design would be nice though. (Or a complete new design that uses the mods I've installed xD)

The only reason to install SpaceY is if you want really, really big rockets. You should be able to accomplish your Duna-and-back without them, but if you like having more legos to play with, then go ahead; it can't hurt.

 whenever I plan a manoveur node...it just gets complicated

Being able to correctly use a manouever node is a really fundamental skill. I would strongly urge you to use the tutorial section and watch a few videos, and practice. Manoeuver nodes will reduce difficult problems to trivial problems when mastered.

I meant complicated as in getting the normal to have the perfect 0.6 inclination that Duna has...hence the reason for Precise Node
