How high must the internal temperature of the rover be to keep it functioning?
Thanks for your excellent question! For most of the electronics in the Warm Electronics Box (WEB), the minimum allowable flight temperature is -40 degrees Celsius. This happens to be the point at which deg. C equals deg. F, so this also corresponds to -40 deg. F. For the battery, the min allowable flight temperature limit is warmer, at -20 deg. C (or -4 deg. F). This is a challenge durning the cold Martian nights (hundreds of degrees below zero!), but our well-insulated WEB allows these internal temperature limits to be met. Thanks for your awesome question! Todd J.
