Ahahah congratulations! Now, that's one huge ship!

Okay I learned from all your responses and completely changed my plans and (thanks to some redditors too) I managed to get better at piloting and optimized the design A LOT. So here is how the rescue mission turned out! http://imgur.com/a/ZLkbC#0 Thanks everyone, you have been my ground control all along! Now I will keep using this rocket design to rescue all of the remaining kerbals that are not "busy" in my Mun base (and here is my base, I'm very proud of it http://imgur.com/a/WT5bP) Have a nice day!

Okay, that was very clear! I could not understand some of the replies here but yours was really good. Thanks eveyrone, I will keep trying! :okay: That is the part that discourages me when building rockets. About MechJeb and other mods, I like to keep the game vanilla because I feel like I should learn more stuff before starting to use gameplay influencing addons. I am using a few addons like the B9 pack and other stock-like parts because they will most likely be in the game anyway in the next update or two. Have a nice day!

Damn, that was a hard answer with hard questions... I am planning some rescue missions, it's not that I need that specific lander, It's just that the design looked "smart" (with no calculations of any type made AT ALL, because I have no idea where to start with that stuff, let's just call it "cool"). So what I need is a lander that can: - get around the Mun - land (possibly near someone to rescue!) - go around and save a couple more green demsels - go back to Kerbin and bring them home safely! And why not, I would love to understand a bit more of mass/thrust ratios and the relation with delta V. In the meantime, I will be just throwing stuff in the sky and still be amazed if I can actually accomplish anything at all

How did you calculate the delta V of my lander?

You guys are amazing, I learned so much in a few posts! @Francesco I would love to make my second stage last for as long as I can, just to make sure I can go around on the Mun with enough fuel to move around on the planet and rescue as many as I can.

Hey there! After all my munar landings I finally decided to start rescue missions for all those guys I got stuck on the Mun. Here is my noob problem: I have no idea how to dock, so refueling in orbit is still not an option for me. I made this http://imgur.com/a/gWewk#1 Lander wich I consider essential and minimalist. However, no matter how many tank/engine/booster combinations and designs I tried, I still have a hard time bringing enough fuel in orbit and beyond. Can you guys help me with the construction of a smart-designed rocket that can accomplish this "crazy" task? Have a nice day!
