The Mars Atmosphere and Volatile Evolution Mission (MAVEN) has observed the Martian upper atmosphere for several months. The Imaging Ultraviolet Spectrograph (IUVS) is able to measure the resonance line of the atomic oxygen at 130.4 nm. From this emission we are able to derive information of the oxygen content in the Martian upper atmosphere and its variability. Atomic oxygen is a key species to better understand the chemistry, heating, dynamics and escape of the Martian upper atmosphere.
