Hello everybody. I am kind of new to Kerbal Space Program, but I already have 36 hours of gameplay and I can make my way around... But I'm not a good rocket engineer I am in career mode in 0.23 and I got my first kerbal to the mun, but the problem is... That I didn't calculate the fuel right and Bob Kerman with the lander are stuck in the Mun, with no fuel and limited Life Support (I got only ONE shot at this). Now the complicated part: I am not advanced in the tech tree and I only got 1.25m Rocket parts. Fortunatelly I have all 1.25m fuel tanks and Engines, but I do not have RCS, only the simplest inline reaction wheel and AV-R8 Winglet, no precision engineering (small fuel tanks, RCS tanks, fuel ducts, etc) and no docking. I have the Stayputnik, basic eletric systems (small batteries and 1x6 and 2x3 solar panels), basic communications (communotron 16 and Comms DTS-M1) and LT-1 and LT-5 Micro landing struts. Mods I'm using: Remote Tech, KW Rocketry, B9 Aerospace (do not have any aerodynamics yet, so it doesn't make a difference), Ferram Aerospace Research, Deadly Reentry and TAC Life Support. I have a Simple but working Communications Satelitte Orbiting Kerbin, so sending probes to the Mun are not a problem (as I did send before... it's still there ) So could you help me build a Rocket with the limited parts I have that is able to Land on the Mun and come back?
