Mars Express - cpshooter/geoML GitHub Wiki

Mars Express, the European Space Agency's (ESA) first planetary mission to Mars, was launched on June 2, 2003 and inserted in Mars orbit on December 26, 2003 (Bonello et al., 2005). Mars Express carries eight instruments for different science objectives, of which the OMEGA (Observatoire pour la Minéralogie, l'Eau, les Glaces et l'Activité) spectrometer (Bibring et al., 2004) is the most suitable instrument for studying the surface mineralogy of Mars. The instrument consists of three subsystems that cover the spectral ranges of 0.36–1.1 μm (VNIR), 0.93–2.7 μm (SWIR1) and 2.5–5.1 μm (SWIR2). Depending on the altitude of the satellite, the spatial resolution of OMEGA varies from 300 m to 4 km, which makes it an excellent instrument to study the mineralogy of large areas (Gendrin et al., 2005).
