MAVEN Neutral Gas and Ion Mass Spectrometer
While NASA rovers, landers, and orbiters have scrutinized the surface of Mars for decades, a key question to understanding the Red Planet's ancient habitability has hitherto gone unanswered: what happened to its atmosphere? NASA's MAVEN spacecraft will fill in this gap in the history of Mars, thanks in part to its Neutral Gas and Ion Mass Spectrometer, or NGIMS instrument. By studying the interaction of neutral gases and ions with the solar wind, NGIMS will observe current atmospheric escape processes on Mars and allow scientists to extrapolate back to the ancient atmosphere. The results could tell scientists just how long Mars was warm, wet, and hospitable, refining our understanding of its early potential for life.
MAVEN will use its Neutral Gas and Ion Mass Spectrometer to study the interaction of neutral gases and ions in the Martian atmosphere with the solar wind, helping scientists to understand how Mars has lost its atmosphere over time.
