I have been having problems trying to reenter and cannot seem to get it to work. I have been testing by starting at a 80km by 80km orbit and deorbiting to between 30-45km periapsis, but every time that I get to the middle layer of Kerbin's atmosphere, the temperature goes up too fast for the shield to get rid of the heat. The shield overheats and explodes with in a minute of entering the middle layer. I have been able to get down safely before with these same trajectories but I don't know what is going wrong. Also, most times that I load a craft onto the launchpad many of the modules load showing nearly full overheat bars that immediately start to reduce and usually my parachutes explode immediately upon the load. Can some one help me figure out what is going on and how to fix it.
