I purchased this one a little while back, have been slowly learning the ropes and making more and more progress. Most recently, I've developed a ship that successfully lands a kerbal on the Mun or Minmus and returns them.
My next three goals are to:
(1) Continue making landings on Mun and Minmus, landing in different biomes, so I can return with more and more Science. I'm getting TONS of science on these trips.
(2) Work on adding a Science Jr. to my lander so I can run more advanced scientific research, return with larger amounts of science.
(3) Try making flybys past Eve and Duna, not necessarily with a Science Jr but it'd be awesome if it DID include that.
I'll post more details later, and even later, screenshots of what I've used to accomplish what I've done. Anybody else play? What sorts of accomplishments have you made? Having trouble figuring something out? Maybe one of us can guide you along. Let's talk KSP!
