- Data access : PSUP high level data distribution and visualization
- Top Ten discoveries of OMEGA:
- The Noachian crust exhibits globally distributed alteration to a variety of phyllosilicates, indicating the presence of water at neutral pH providing potentially habitable conditions
- Identification and mapping of sulfate-rich deposits of late Noachian/Hesperian ages
- The alteration mineralogy changed from phyllosilicate-bearing to sulfate-bearing deposits. The variation in mineralogy indicate a more arid and acidic environment with time
- Identification and mapping of various igneous minerals indicating complex formation and evolution of the crust and of volcanic provinces
- There is no evidence for extensive involvement of surface water in generating hydrated or hydroxylated minerals during the Amazonian period
- Direct detection of mesospheric CO2 ice and H2O ice clouds
- First detection of O2 1.27 μm nightglow emission and comparison with general circulation model
- Water cycle was constrained thanks to mapping and monitoring water in polar caps, frosts and atmosphere
- Global mapping of anhydrous minerals
- Olivine global distribution and new constraints on the magmatic and volcanic evolution
