2. Mars Exospheric Neutral Component Analyser(MENCA) - it analyses neutral atom present in Mars' upper atmosphere
3. Mars Colour Camera(MCC) - it gives images of surface features
4. Lyman Alpha Photometer(LAP) - to measure relative abundance of deuterium and hydrogen in upper atmosphere
5. Thermal Imaging Infra Red Spectrometer - to study different mineral present on the surface
