Introduction:
The Supercam Instrument Onboard The Mars2020perceverance Rover [1, 2] Has The Capability Of Performing Several Active And Passive Techniques. Passive Spectroscopic Measurements Of The Atmosphere
Are Possible In The 0.4-0.85 (Vis) And The 1.3-2.6 (Ir)
Micron Ranges [3, 4]. Since Landing In Jezero Crater In
February 2021, Supercam Has Performed Numerous
Atmospheric Observations.
The Technique Used Is Called “Passive Sky”, And
Has Already Been Successfully Conducted By Chemcam On The Mars Science Laboratory Rover [5]. Supercam Extends On The Capabilities Of Chemcam, By
