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.

MAVEN Reveals Mars Argon Loss to Space
Read moreInfographic explaining the MAVEN argon results. Enlarge or click "download" for print-resolution versions. Also available in text-readable PDF for the visually impaired. || Solar wind and radiation are responsible for stripping the Martian atmosphere, according to results from NASA's MAVEN mission. By measuring light and heavy isotopes of argon in the Martian atmosphere, scientists have determined that the majority of the planet's air and water were removed to space by sputtering. In this process, ions from the Mars atmosphere get picked up by the solar wind and slammed into other atoms at the top of the atmosphere, knocking them into space. Scientists used measurements of light and heavy argon from MAVEN and NASA's Curiosity rover to determine that sputtering has removed 65% of Mars' argon to space, along with the majority of other gases like carbon dioxide. Over billions of years, this transformed Mars from a hospitable environment into the cold, dry planet that we see today.Learn more about the MAVEN argon loss finding. ||

MAVEN Particles & Fields Package
Read moreTo planetary scientists, the Martian atmosphere presents an intriguing mystery: today it's a thin, cold wisp of carbon dioxide with just one percent the pressure of Earth's atmosphere, but long ago it was thick and warm enough to support lakes and rivers on the Martian surface. How did Mars lose so much of its early atmosphere? Scientists think that the solar wind may be responsible, and NASA's Mars Atmosphere and Volatile EvolutioN (MAVEN) spacecraft is designed to find out. The instruments of MAVEN's Particles & Fields package will study the interaction of the solar wind with Mars's upper atmosphere, helping scientists to better understand how Mars became the freeze-dried planet that we see today. ||

MAVEN National Air and Space Museum Presentation
Read moreAncient riverbeds, crater lakes and flood channels all attest to Mars's warm, watery past. So how did the Red Planet evolve from a once hospitable world into the cold, dry desert that we see today? One possibility is that Mars lost its early atmosphere, allowing its water to escape into space, and NASA's Mars Atmosphere and Volatile EvolutioN (MAVEN) spacecraft will investigate just that. On September 25, 2013, MAVEN Principal Investigator Bruce Jakosky delivered a presentation at the Smithsonian National Air and Space Museum, discussing NASA's next mission to Mars. An edited version appears below. ||

MAVEN Imaging Ultraviolet Spectrograph
Read moreThe philosophy of NASA's Mars Program has been "Follow the water," but "Where did the atmosphere go?" is still a lingering question. Although fluvial features such as dry riverbeds are visible on Mars, the atmosphere today is too thin to support liquid water, implying that Mars once had a thicker atmosphere that was lost to space. NASA's Mars Atmosphere and Volatile EvolutioN Mission, or MAVEN, will test this hypothesis. As part of its remote sensing instrument package, MAVEN's Imaging Ultraviolet Spectrograph (IUVS) will look at isotopic hydrogen ratios in the upper atmosphere of Mars, helping scientists to determine just how much water once flowed across the Red Planet. ||

MAVEN Magnetometer
Read moreWhen you navigate with a compass you can orient yourself thanks to Earth's global magnetic field. But on Mars, if you were to walk around with a compass it would haphazardly point from one anomaly to another, because the Red Planet does not possess a global magnetosphere. Scientists think that this lack of a protective magnetic field may have allowed the solar wind to strip away the Martian atmosphere over billions of years, and now NASA's MAVEN spacecraft will study this process in detail with its pair of ring core fluxgate magnetometers. ||
