    "description": "When 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. || ",

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. || ",

            "description": "When you take a look at Mars, you probably wouldn't think that it looks like a nice place to live. It's dry, it's dusty, and there's practically no atmosphere. But some scientists think that Mars may have once looked like a much nicer place to live, with a thicker atmosphere, cloudy skies, and possibly even liquid water flowing over the surface. So how did Mars transform from a warm, wet world to a cold, barren desert? NASA's MAVEN spacecraft will give us a clearer idea of how Mars lost its atmosphere (and thus its water), and scientists think that several processes have had an impact.Learn more about these processes in the videos below! || ",

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. || ",

            "description": "The 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. || ",
