Awesome i did it, i went to the mun and back with some adjustments, i think i understand how things works a little better, my next step or question would be, how to get farther away from kerbin, say i want to land on Duna, and go back, how should i approach that? looking at the Delta-V map on page 1, i need 7490m/s to get there? and how much to go back? if so that means i can use the same rocket to get to duna?... EDIT: The thing is that, the bigger i build my rockets the less efficient they are, i can't really do better than 8000m/s delta-v any advice?

I did that, i can land on the mun most of the time but i burn so much fuel so i don't crash that i don;t have enought to get back to kerbin... guess i'm not doing the landing right... but hey i landed i did it!!!

Waoh so many answers you people are great thanks a lot for all the help here i go with some more info: Boosters get me around 8-10k then i start my turn around 12k i aim for an orbit of 90-100 plan my circularization at the apoapse, i start to burn round 15-30 before eta, usually that stage dies after 50% of the burn i have to use my lander to finish the circularization, from there i just target the mun and i can make it there but not with enough fuel to land... I did try with liquid boosters got to the mun and i'm able to land but i go throu all my fuel while landing, i guess i need a landing tutorial for the mun i guess i'm wasting fuel... Thanks again for the help everyone

Hi, i'm new to the game and i have been reading the wiki a little, seen some vids, do some (explotions!!!... ehem...) testing with my rockets, but i can't make it to the Mun, land and return to kerbin, i have done a lot of math to get TWR, Delta-V and all that jazz but i don't understand why i can't make it, i'll try to describe everything so you can help me oh and i'm playing on carrer mode it's sweet!!! Stage I: Mk16 Parachute, Pod Mk1, 2x Z-100 Bateries, FL-R25 RCS Tank, 2x Goo things, 4x RCS Thrusters, 4x LT-1 Landing Struts, 5x Pegasus Ladders, LV-909 Engine and a FL-T400 Fuel Tank Delta-V= 1969.795 TWR = 1.025 Stage II: Stack Decoupler, FL-T200 + FL-T400 Fuel tanks and a LV-T30 Engine Delta-V= 1761.053 TWR= 2.964 Stage III: Stack Decoupler, FL-T800 Fuel Tank and a LV-T45 Engine Delta-V= 1837.362 TWR= 2.025 Stage IV: 4x Radial Decouplers, 4x AV-r8 Winglets, 4x Nose Cones and 4x Rockomax Boosters Delta-V= 2587.647 TRW= 3.437 Total Delta-V= 8031.710 The Isp i used on the Stages II and III was and averge from Vacum / Sea level Here a photo: https://skydrive.live.com/redir?resid=5FB025AC43809FB3!439&authkey=!AIcnYHunk9Mfw-k&v=3 And that doesn't do the job... i just get to make a round orbit and some that's it... please help me i don;t understand what i'm doing wrong... thanks in advance
