Lots of great designs! It took me while to get a good 3 kerbal lander, just try many different designs and you'll find something that works. I sent many landers to the moon, but always forgot enough fuel to bring everyone back... Using the damned aerospace crewtank I made 13 kerbal Mun lander, that has the ability to get everyone back to Kerbin under a parachute descent: I used Mechjeb for the detailed information, but its perfectly pilot-able without it. Of course Bill, Jeb, and Bob were in the in command capsule!
