Well I am new to Kerbin. Just moved there from Earth. With that said I have only done a few missions and have not yet landed on Mun or Minmus. During my trials I have left a few space craft that cannot get back to Kerbin. So I have tried to save my Kerbals lost in space. I have 6 crafts that are stuck, 4 in Kerbin orbits and 2 in the Sun orbit. I have saved 2 Kerbals so far. I have 2 more to save in Kerbin orbit and then I will try to rescue the 2 orbiting the Sun. I love this game now that I am understanding the docking and maneuvering. I just now need to learn landings.
