Still very much in beginner mode, here. With some help from the forum, I'm now coming close to finishing the career tech tree. All my work so far has been in Kerbin orbit, Minmus and Munar landings. I've also successfully complete a pair each of orbit-and-return gravity probe missions to Kerbin's satellites. Over the last week, I've done lots of testing trying to land my Mun Lab with a rover. I have proven successful in adapting a 55 ton LKO lifter (based on screen shots of the LT branch of Munshine V), landing on the Mun and even demonstrated that return to Kerbin is completely possible with my return vessel. If only the Mun hadn't gotten in the way. The only trouble with my successful landing was that the legs on Mun Lab 01 compressed too much to provide enough clearance to drive (or push) the rover out from underneath. Since then, I've redesigned the lab with greater clearance and also more thrust. This morning I got Mun Lab 02 into Munar orbit and tried twice to land it, only to be thwarted by a combination of uneven terrain, achingly slow craft rotation and the resulting panic. If another redesign is needed, I will add some RCS. Still, with a little more practice, I am certain to land this beast, give the near successes I've already achieved. Everything I've read about Munar landings is true: try your hand on Minmus first. It's harder to get there - due to distance and orbital inclination - but it's far easier to land. I made two landings on Minmus before trying my first Munar landing. I suppose I may have to take a Mun Lab to Minmus as well. I've actually landed twice on each satellite, and the second Munar landing had a toy rover. This success is what lead me to want a larger, more robust lander with science instruments and a local lab for delivery. The plan is to ferry seismic and gravity data from multiple Munar biomes, transfer as much of it onto the return vessel as I can, and return for massive science.
