Building a sutiable rocket tp get to the mun?

[al.wallace]

So the story goes,
Ive been having a problem with getting to the mun.
The problems not about getting to the mun but actually building a suitable rocket to get to the mun. "Watch Scott Manleys videos," you cry. Well actually in this case Scott Manleys videos dont actually help me!. I do know some stuff about building a mun rocket though, that there has to be 1 stage that lands you on the mun and gets you back to kerbin, the second stage is the one that gets you on a transfer orbit from kerbin to the mun and finally the third one thats gets you into orbit and out of kerbins athmosphere. So Generally I need help on how to build a rocket to the mun and what to put in it. Another thing to note is that i use mechjeb every now and then.

I basically had the same problems, Scot manley's videos are good quality, but they don't help in how to build your rockets.

My first advice is to go to Minmus first though.
It might be a little farther, but it is way easier to find flat spots (frozen oceans are plenty on minmus), and there is way less gravity, meaning that you need less fuel to be able to safely land.

Give me a bit of time, and I will get you a basic setup using basic parts only, so that I can explain with a working setup before my eyes.

Going to the mun is dirt simple. Just get into a 120km orbit and start burning orbital-prograde. Once AP reached 8-10-11 milliom km you will, in time provided a bit of luck (rather then knowing what your doing) get into a mun-encounter. Once @ the encounter, burn retrograde at the Apoapsis untill your orbit is done.

Thats at least how I do it.

look closely at the "kerbal-X" prebuild ship, this thing is able to get to the mun, land and return. if you let mechjeb fly in the most effiencent way possible, you can even 'softland' the thing back on kerbin (safe landing on the legs, using the engine)

[Furry Eskimo]

Why not try using the premade rockets, or building those you see others have, start simple, it's ok to. I often use boosters or jet engines (lots of them!!) to boost my rockets high up, then drop a stage an boost higher with a mainsail engine and an orange fuel tank, then drop that high up and with a final boost! stabalize an orbit. Then use just a little fuel and a nuclear engine to move over to the mun a small rocket, it takes very little to return :)

Already had this uploaded for somebody else, so give this a shot as maybe a guide. It might not be the most 1337 min/maxed lifter, but I think it looks cool, and it does decent work. If you don't want to use the lander, just delete everything above the tug's 2.5m docking port and build your own. Lifter should be good for anything at or below 30t.

This configuration is meant to rendez-vous with a crew vehicle in Kerbin orbit before ditching the recoverable tug vehicle, so you'll need to supply one of those yourself. Or you can just try flying it to the Mun as is... I suspect that between the tug and the lander there is enough fuel to do so and possibly return to Kerbin orbit.

Caution: you'll need the following mods: drop tank fuel gauge, quantum struts, KSPX.

I won't be giving out my craft file, because I did a lot of mistakes, mostly I put way too much fuel for the ascending phase, and the landing/return phase is a bit tight.

But some things to consider:

1. The landing/return phase.
You will want engines that are not too tall, so that the landing legs can touch the ground. I tend to use aerospike, because they are relatively powerful, and waste less fuel than most engines.

What I do is to put two fuel+engines for this stage on the sides of the command pod (lander can for me).

Do not forget some solar panels, the landing legs, the ladder, and the parachute for the landing on Kerbin.

Basically, this stage is relatively small and light, but you need to have enough fuel for the return too, so more than the default tank might be good.


2. The spacial phase (from Kerbin orbit to Mun or Minmus orbit)
This phase can be easily satisfied by using the nuclear engine, and you don't need too much fuel. If you have MechJeb installed, you might want to see your dV for the stage, because you will need something around 1500 to be sure.


3. The Ascend phase (to kerbin orbit)
You will want to have a lot of fuel, and a lot of power in the engines.

I usually use large fuel tanks as well as Mainsail engines, because I still am not as good as should be.

Asparagus staging can help a lot, and don't forget struts everywhere.



If those tips are not enough, I will provide my craft file, but be aware that it has way too much fuel for the ascend, so you can even do the phase 2 with it, and the return can be a it tricky, with just enough fuel to catch atmosphere, so you might need to use the RCS as a propulsion to correct a bit.

[Power and Wealth]

Just overcompensate. 4 nuclear engines and a 1440 fuel tank in a 120km orbit will get you to the mun xD

[Jaśko]

Kerbal X is capable of going to Mun, landing, and coming back to Kerbin safely. Try to fly it, see how it's built and how the staging is set-up.

[al.wallace]

I need to comfirm would this ship be good for a munar mission?

Its nice to know ksp on steam has a big community ready to help

I'd say that's overkill for a mission to the Mun. As mentioned earlier, the stock Kerbal X is more than capable of completing the mission. One thing I would suggest, if you plan on sticking with this design, is to trade those Torodial Aerospikes for other engines. The LV-N Atomic Engines are incredibly efficient and will likely do a round trip to the Mun with fuel to spare. Using advanced crossfeeding (asparagus staging) for your main launch stack would increase efficiency too. I would strongly recommend a complete redesign of your mission package, as the LV-N stage will likely be underpowered if you're still suborbital after you decouple the centre stack. The picture underneath may give you some ideas for a landing stage if you're still stuck.

But isn't part of the fun of this game based on being able to go overkill for a small mission?

I even built a 5m rocket just to put a simple satelite around Kerbin, just because I could, and it's more fun for me to have this kind of ship rather than some small rocket that can ddo exactly the same job.

Good point, but overkill usually comes with its own complications. A Mainsail launch stack is usually less responsive than a smaller rocket, and the sheer amount of thrust hitting that mission package at once could cripple the LV-N, especially as parts seem to be much more squishy after 0.21.

[Fel]

Yeah, it does happen if you go full thrust in atmosphere.

But for the unresponsiveness, I just add the large reaction wheel, and sometimes it even goes nuts because it turns way too much.

I do get the fact that I can be much more simple on my designs, but I get a lot of my fun from trying to fly those things, and all the better when they break because I put too much thrust.

Admitedly, I only made 1 mission outside of Kerbin and its moons, after more than 100h of gameplay, and I am mostly playing around with mods.

Like making a ball of fire from a 5m rocket that thrusts so much that you have reentry effects at launch.

Hey.... Are you gonna help him when he wants to get to Laythe but his rocket is so wide his monitor isn't big enough?

I can see the next thread - "You guys said build BIG but it won't take off/falls apart/explodes. HELP!!!" :)

@OP - hours. lots of 'em. Trial and error is the best part of KSP. There is huge satisfaction to be had in getting that finely tuned piece of rocketry into space or at it's destination. Sure it's a game... But it becomes much more than that after your first success. Much more.
