Electronics can get hot. On Earth, the heat can dissipate as convection through air, but unfortunately there is no air in space! This means that it is crucial to understand the thermal profile of all electronics on board so we can tackle heating and cooling problems on the satellite. Imaged here is a thermal image of our UHF communications board captured on a FLIR infrared camera while it is running at full capacity. The hottest component on the board heats up to 51.5 degrees Celsius.
