Thermal Control Is Radiation-Dominated and Non-Negotiable
In vacuum, there is no convection to fall back on — every watt leaves by conduction or radiation, on a mass and volume budget that leaves no margin for a redesign after launch.
Why thermal decides the outcome here
Orbital thermal cycling, solar view-factor changes every orbit, and mass constraints mean the thermal control system is designed once and has to be right. There is no field service call in orbit.
- Radiation-dominated heat rejection in vacuum
- Orbital thermal cycling with changing solar view factors
- Mass and volume constraints on thermal control hardware
- Cryogenic subsystem thermal isolation
- Qualification evidence with no in-orbit correction possible
- Surface-to-surface and solar radiation in vacuum
- Orbital thermal cycling and eclipse transients
- Conduction-only heat paths (no convection in vacuum)
- Cryogenic thermal isolation and multi-layer insulation performance
- ECSS-E-ST-31C (space engineering — thermal control)
Simulation shows the design. Measurement proves it.
