I'm looking to research on mounted cameras on supersonic planes, sounding rockets and what cameras can survive the flight as temperatures go below upto -50 C. The range I'm looking at is about -25 to -50 C, what still functions without much worries and if there are things needed for them to work at such temperatures.
Edit: To clarify, we're working on an object that will be heading to the high altitudes and there's a point at 10 km altitude where temperatures go down to -50 C . We'd like footage at a decent fps, but we're willing to sacrifice it in case of poor performance at low temperatures. Batteries will not be a problem as they will be externally managed during the flight and can go to lower temperatures. We'd like no distortion and sufficient changes in exposure for various light brightness as the object travels through layers of atmosphere.
