So I just made my first trip to the surface of the Mun and was coming back. Unfortunately, I didn't have enough liquid fuel, so I had to use my RCS system to get back to Kerbin - and I had enough. I went into Munar orbit first then started my "burn" to get back to Kerbin. As I was about to get into Kerbin orbit, using my full RCS forward thrusters, my ship blew up. Any idea why? I mean it was a simple craft at that point with a command module with solar panels, two RCS tanks, and four thrusters. Do they overheat? I didn't see anything.
