MAVEN NGIMS Mass Spectrum

Mass spectrum obtained by NGIMS showing the different neutral and ionized species in the upper atmosphere and ionosphere. Although the composition at these altitudes has been measured twice, by the Viking lander entry vehicles, MAVEN represents the first comprehensive measurements at these altitudes.
