ORBITER-FORUM will be temporarily closed at 2026-07-23 18:00 UTC while we complete some OF maintenance tasks. The amount of downtime is expected to take up to one hour, but probably less.
Patch 1.0.3 is up.
What exactly do the new radiators do?
I have a feeling that they are not used in an XR sense.
As in, you will not necessarily burn up without them simply from being in space/exposed to the sun?
Thermal:
* 1.0.3 features a revised thermal mechanic to better balance heating/cooling between pods and spaceplanes.
* Parts now have separate internal temperature and skin temperatures.
* Skin temperature is the temperature used for radiation and convection, as well as engine exhaust damage.
* Part internal temperature is increased by modules that generate heat and is used for part-part conduction.
* Part internal and skin temperature also conduct between each other.
*Solar panel efficiency is now calculated based on skin temperature.
* When in an atmosphere, there is a divide between the exposed (to convection) and unexposed skin temperatures.
* When not in an atmosphere, only one skin temperature is tracked; the two temperatures are unified on atmosphere exit.
* Radiative outflux and influx is tracked separately for exposed and unexposed areas of skin (since the shock temperature is much higher than ambient temperature).
