Built and successfully landed my first Munar outpost, consisting of a Cupola, Lab, 2 person Lander, some Science batteries solar panels and 4 LV-909 engines to land it all. It's on the Mun in the Farside Crater. On landing, the 2 Kerbals EVA'd, planted flags did some science and took samples back to the Lab for processing. Now though, every time I go back there from the tracking station, the Lander explodes killing them both and leaving a pile of junk . What to do?
