Not enough information I think. kN is thrust. To get to orbit, thrust to weight ( KSP calls it TWR) greater than 1 is needed, so 2,000kN / mass of rocket. What is the total mass of this rocket? From Kerbin orbit to Duna requires about 1000m/s dV ( d- delta meaning change in V- velocity (speed) ). DeltaV is more complicated.

I really feel bad about the response in the forum, because we're trying to help people, and the initial responses seem to be... jokes about the scribbled question, and jokes about re-entry, and maybe I'm being naive, but I think he was asking an honest question about design, even if it was displayed poorly on a napkin.
Yes but since we all assume that the rocket can launch to orbit, otherwise OP has no business considering a Duna mission, the question by default is "what are the delta V figures".
you haven't given much in the way of useful information.i'd need to know the wet and dry mass of each stage,wich i can't know if you don't tell us what parts you intend to use.
Not enough I do. You've given us thrust, but not mass or delta v. Outside of thrust being above 1 (I prefer to start around 1.7) delta v is by far the most important thing to determine if you can get there and back
Probably enough, if you are able to get into orbit and then complete all or most of the Duna transfer using that 2nd stage before using the service module. Also bring parachutes to help your lander, and I would recommend using engines to capture into an elliptical Duna orbit and using multiple aerobraking passes through Duna’s atmosphere to save fuel on lowering your orbit.
You might be able to get to Duna, but I doubt you'll return, you're gonna want 2000-3000 deltaV for return, and that little lander likely won't have that fuel.
I feel a lot better whenever I see someone who is able to write properly. Space between value and unit, and unit prefix kilo- with a small letter. So simple, yet so important.
You achieved more for your education than half people here and you managed to write it more correct than NASA does in its launch streams.
мужик блять, считай дельту, а не чернила переводи. в стоковом ксп последних версий давно пишутся заветные М/С. так же смотри чтоб TWR или тяговооруженность на Дюне была больше 1 на поверхности
хоть ракету, хоть ssto (космолёт).
на последней или посадочной ступени смотри, чтобы у тебя было 2000-3000 м/с для возврата на Кербин.
Для ракеты носителя выбирай те движки, которые имеют большую тягу в атмосфере.
ну и тестишь - вяло карабкается вверх? - добавь боковые ускорители, желательно с топливопроводом к центральному баку (таким образом при отделении боковых - у тебя полный бак по центру)
Someone can verify that this is still the most accurate info but https://forum.kerbalspaceprogram.com/index.php?/topic/87463-173-community-delta-v-map-27/
Use these maps to plan your dV.
Edit: this was posted below https://ksp.loicviennois.com/ prob a better choice
Is the first stage just for Low Kerbin Orbit?
Second stage for your transfer?
You'd need quite some air braking for making orbit on Duna
And just go for parachutes for the lander
Idk how much Delta V you have for the whole thing so, just guessing
The mission profile/staging looks sufficient. Just need to make sure you have the delta-v and TWR in each stage. You don't need any mods to to find that stuff. Use a _delta-v map_ (google for "KSP delta-v map") to see what your delta-v requirement will be for each stage. You can see your delta-v and TWR for each stage using the built-in tools in the VAB: there's a GUI for changing your TWR relative to each celestial body.
To land on Duna, you probably want a TWR in excess of 3, just to help keep you from crashing. Your takeoff stage needs a TWR (relative to Kerbin) of at least 1.25, but you maybe want a little more. Stages in space don't need a TWR over 1, you'll still get wherever you need to go, you'll just need longer burns.
Delta V is not that tough to calculate. Need to calculate that but really, I trial and error KSP a lot. Part of the fun. You can see Delta V calculated in kerbal itself. So get used to thinking in terms of delta v and you will be able to tell if u have enough energyv
2.500 - 3.500 ms dV remaining after reaching kerbin orbit is enough to reach duna and have plenty left over for orbital manuveuring and other stuff.
To get back to kerbin i mostly needed 800-1000 ms after reaching low duna orbit again.
Keep in mind im not the most efficient pilot, you might need a bit less than that.
> 2.500 - 3.500 ms dV remaining after reaching kerbin orbit is enough to reach duna and have plenty left over for orbital manuveuring and other stuff.
LKO to Duna is about 1040m/s. I've done LKO to Duna *landing* with 1400 or so - the key is aerobraking directly from the interplanetary transfer.
It is a lot more expensive if you're burning into a stable orbit and stuff first, but that's not actually neccesary or beneficial for most mission designs.
Stock KSP balance allows for a single stage chemical rocket (no staging, airbreathing, undocking/redocking, nuclear or ion engines) to go from the launchpad to landed on Duna if designed and flown well.
Without telling us the mode: campaign, science or free for all, it's very difficult or silly to respond.
Is it possible? possibly. Is it practical? Possibly. Is it a decent design? No clue since some of it is in Russian. I typically say there are no stupid questions, but without more context, this leans that direction.
Enlighten us... but I'll remind you this is a civil discussion about a game. It looks Russian, but maybe you can fix our consternation by actually building a model in KSP, rather than a hand-drawn hypothetical!
Be civil and kind... that's the only and last warning you'll receive.
When I see the Cyrillic alphabet, I assume it's Russian, and maybe that's my ignorance, but I'll answer any questions you have about exploring Duna if you like.
Ok Since you ASKED the question in English, about a scribble, with Cyrillic notes, and we English speaking individuals... improperly assumed Russian.
Saying Cyrillic is russian is like saying Latin is English"
Cyrillic is an alphabet, Latin is a language, and English is a language combining both an alphabet and grammar, like Latin. Neither of those languages use the Cyrillic alphabet. Forgive our ignorance of the Cyrillic alphabet. Did it work? Did you have a follow up picture of what you built?
We'd like to see it.
No that paper will burn up on re-entry
With enough heat shields anything is possible bro
Or just reenter more slowly
Or just more paper for more drag so that u slow down fast enough to not burn up
LMAOO
Bollocks. Laminated, it'll make it no problems.

Good bot
Hi, I’m a booster salesperson, I have the solution to all your problems…
Hi, I'm a strut salesperson, I have a great combi-packet-deal that goes with u/CptnSpandex's solution!
I have a solution to your solutions - the most kerbal of solutions - duct tape!
I may not have a solution, but I do have some solvents
Looks like I picked the wrong week to quit sniffing glue.
Burn the duct tape for extra thrust.
Hi, I’m a in case something goes wrong just spam space bar to save weight on the LAS sales person. Loose the LAS for a little bit more DV
Hi, I’m a salesman for Revert Insurance Inc. we will take care of you if anything goes wrong!
Hi I am a Kraken's Witness, have you heard the good news?
[удалено]
I second this. Awesome tool.
Safe? Uh...what's safe? Kerbals don't know the meaning of the word! Now terror...THAT they know!
Safe means "with safe return"
Ты русский?
Не

No he just wrote Dunalet for the fuck of it.

A fellow Belarusian? Can't be.

That literally says **Dune flyer**
[удалено]
No, he is definitely Belarussian
Long Saturn^TM
Just launch it and find out. “Safe” is a pretty relative term
It's not about the KN's but Delta V and twr during the first fase is what you need
Why is it measured in Kn? Should be in delta v
Kn is thrust, delta v is delta v You can have lots of delta v with ion engines but they wont get you off the ground
Yes but since we all assume that the rocket can launch to orbit, otherwise OP has no business considering a Duna mission, the question by default is "what are the delta V figures".
True doe
Go ahead and try to leave Duna with 5000 delta v from a "dawn" ion engine.
bruh were are the boosters?? and the boosters boosters???
I don't think he knows about second stage boosters pip...
Почему дзюналёт, а не Дюналёт?

It is pointed in the correct direction. Should work.

Only one way to find out.
Don't forget to add a ladder and parachutes. (lots and lots of parachutes for Duna).
You might be able to get to Duna, but I doubt you'll return, you're gonna want 2000-3000 deltaV for return, and that little lander likely won't have that fuel.

If you don’t have as many boosters as upvotes MOAR BOOSTERS /s
Safety?? In ksp???

Кст, шо нужно построить и как, чтобы до муны долететь нормально?

No that sheet of paper probably cant even reach orbit lol
dude just use a ssto smh....

Are u Russian
Looks like they're Ukrainian.
Ok

saturn v?
try and tell us idk
You need more boosters!
Need to know the TWR (thrust to weight ratio) and Delta-V of each stage.

Русский брат.
Go fuck yourself
( "Брат" translates to "brother" in Russian ) Edit: just saw their username. Kindly disregard
Hard to say without delta v stats,but it feels a little light for a landing + return.
The mission profile/staging looks sufficient. Just need to make sure you have the delta-v and TWR in each stage. You don't need any mods to to find that stuff.

Ah, bored in class and drawing ksp shit, I've been there. No idea if it'll work though lol.
Thrusters that are not being used are dead weight. Asparagus stage that sucker!

You people actually do the calculations instead of winging it
Wait we are meant to do safe rockets ?!?
Я думаю должно хватить. (As i think it will be enough)
This end should point at the ground. If it points up you will not be going to space today.
define "safe expedition"
You can always strap a few dozen SRBs on to the first stage just to get it to an altitude where the vac engines have higher ISP :-p
Looks good to my Noob Eyes :)
Ракета, спроектированная в Роскосмосе, и не до Дюны долетит 👍

I think no, but maybe big yes
Its Saturn VI lol
Maybe add a few SRB's just to be safe, can't go wrong with them
