Introduction:
Nomad Is A Suite Of Three Spectrometers Onboard The Exomars 2016 Trace Gas Orbiter, Designed To Measure The Constituents Of The Martian
Atmosphere In Unprecedented Detail [1]. The Three
Channels Observe Gas Species In The 200-650 Nm And
2.2-4.3 Μm Spectral Regions, In Nadir, Limb And Solar
Occultation Modes [2]. Nomad Has Been Operating
Continuously Since April 2016 And Has Already Generated A Wealth Of Data About The Atmospheric Constituents And Processes On Mars.

Lno Also Observes The Nightside Of The Planet Occasionally, Plus The Mars’ Limb On Both The Dayside
And Nightside To Search For Non-Lte Co2 Emissions.
Recently, Observations Have Been Made Of Phobos And Deimos: Phobos Is Certainly Observable By
Lno; However Deimos Is Potentially Too Small And
