Just FYI:
I had a strange encounter on Maia A 7. While I was checking out a POI and flying into the center of it in about 1.2km height, I got distracted and started to fall. While I made my descent, I boosted up to get out of the gravity well as usual. After completion of the boost and getting back to 900m-ish, my heat started spiking for no reason I could see and I started taking heat damage. I panicked and crashed my asp into the dust of the 3.8g world.
I have no explanation for the heat so far. It should not be possible to be friction due to atmosphere, because Maia A 7 has none to create it I think. Otherwise we would not be able to land on it at this stage of horizons, right? I have crashed my ship on this godforsaken rock before and made similar maneuvers too without the heat spiking. I just wish I could have taken a look at that POI to see if it were anything out of the ordinary causing this before the ship broke apart...
This happened to me also, although I did not crash my ship, I think I managed to record the strange heat damage event. It was like I hit a hotspot. I was in my conda and thought it was just gravity causing my thrusters to overheat. Not sure if it was the same planet. Will check when I get to my PC
