The ExoMars Trace Gas Orbiter (TGO) is in orbit around Mars since 2016. The main goal of this mission is to understand methane and other atmospheric gases in the atmosphere of Mars.
Measurement instruments for Mars research on TGO:
- NOMAD:
A high resolution solar occultation and nadir spectrometer
A suite of three spectrometers designed to detect traces of the components of the Martian atmosphere and to map where they are on the surface - ACS:
Atmospheric Chemistry Suite
Three spectrometers for mapping gases, dusts and clouds - FREND:
Fine Resolution Epithermal Neutron Detector
An instrument for measuring the hydrogen content of the surface and subsurface - CaSSIS:
Colour and Stereo Surface Imaging System
A camera for taking high-resolution images of the Martian surface
