It seems that there hasn’t been any detailed specifications of the scientific instruments of the now-about-to-be-rolled-to-launch-pad of the Chinese Tianwen-1 Mars Orbiter and @PRCMarsRover missions in English from anywhere I have seen - at least till now!

Hopefully this will be useful for interpreting what abilities the orbiter and rover will have and also assists in public data analysis when they come later.
