Electronics to be used in space must be hardened against: - radiation: electrons, protons, heavy ions (MOSFETs are very vulnerable) - cold temperatures (up to -235 degree celsius) - high temperatures (up to +250 celsius, and there's no air-cooling in space) The performance of electronics vary greatly depending on radiation amount and type, and temperature. You can absolutely not throw consumer electronics (GoPro) in deep space and expect it to function.
