            "title": "Is This How Mars Lost Its Atmosphere?",
            "description": "Mars is losing its atmosphere. Over billions of years, the Red Planet has transformed from a potentially habitable world with lakes, rivers, and a thicker atmosphere into the cold, dry desert we see today. NASA’s MAVEN mission has been tracking this process in real time, catching Mars in the act of slowly sputtering its atmosphere into space.This phenomenon—called “atmospheric sputtering”—happens when high-energy particles from the Sun slam into Mars’s upper atmosphere, knocking atoms and molecules loose. Without a global magnetic field to protect it, Mars is especially vulnerable. MAVEN has shown that this atmospheric escape accelerates during solar storms, offering a powerful view of how the Sun shapes the evolution of planetary atmospheres.The data from MAVEN doesn’t just tell us about Mars—it helps us understand how atmospheres behave across the solar system and beyond. It’s a glimpse into what makes a planet stay habitable—or lose that potential entirely.For more information, visit https://science.nasa.gov/mission/maven/Credit: NASA's Goddard Space Flight Center Dan Gallagher: Lead ProducerPaul Morris: Producer / EditorDr. Shannon Curry: Scientist / IntervieweeWillow Reed: Public AffairsNancy Jones: Public AffairsGreg Shirah: Data VisualizerCindy Starr: Data VisualizerKel Elkins: Data VisualizerWalt Feimer: AnimatorMichael Lentz: AnimatorChris Smith: AnimatorJonathan North: AnimatorBrian Monroe: AnimatorLisa Poje: Graphic DesignerAdriana Manrique Gutierrez: Graphic DesignerKim Dongjae: Graphic DesignerErnie Wright: SupportAaron E.

            "description": "Pulsar J1023 is a member of an exceptional binary system containing a rapidly spinning neutron star. In June 2013, the pulsar underwent a dramatic change in behavior never before observed. Its radio beacon vanished, while at the same time the system brightened significantly in gamma rays, the highest-energy form of light.The stellar system, known as AY Sextantis and located about 4,400 light-years away in the constellation Sextans, pairs a 1.7-millisecond pulsar named PSR J1023+0038 — J1023 for short — with a star containing about one-fifth the mass of the sun. The stars complete an orbit in only 4.8 hours, which places them so close together that a high-energy \"wind\" of charged particles from the pulsar is gradually evaporating its companion. What's happening, astronomers say, are the last sputtering throes of the pulsar spin-up process, where a flow of matter from the companion has, over millions of years, dramatically increased the pulsar's rotation. J1023 now spins at about 35,000 rpm, but the gas stream from the companion is no longer continuous. Researchers regard the system as a unique laboratory for understanding how millisecond pulsars form and for studying details of how accretion takes place on neutron stars. || ",

            "description": "In late June 2013, an exceptional binary system containing a rapidly spinning neutron star underwent a dramatic change in behavior never before observed. The pulsar's radio beacon vanished, while at the same time the system brightened fivefold in gamma rays, the most powerful form of light, according to measurements by NASA's Fermi Gamma-ray Space Telescope.The system, known as AY Sextantis, is located about 4,400 light-years away in the constellation Sextans. It pairs a 1.7-millisecond pulsar named PSR J1023+0038 — J1023 for short — with a star containing about one-fifth the mass of the sun. The stars complete an orbit in only 4.8 hours, which places them so close together that the pulsar will gradually evaporate its companion. To better understand J1023's spin and orbital evolution, the system was routinely monitored in radio. These observations revealed that the pulsar's radio signal had turned off and prompted the search for an associated change in its gamma-ray properties.What's happening, astronomers say, are the last sputtering throes of the pulsar spin-up process. Researchers regard the system as a unique laboratory for understanding how millisecond pulsars form and for studying details of how accretion takes place on neutron stars. In J1023, the stars are close enough that a stream of gas flows from the sun-like star toward the pulsar. The pulsar's rapid rotation and intense magnetic field are responsible for both the radio beam and its powerful pulsar wind. When the radio beam is detectable, the pulsar wind holds back the companion's gas stream, preventing it from approaching too closely. But now and then the stream surges, pushing its way closer to the pulsar and establishing an accretion disk. When gas from the disk falls to an altitude of about 50 miles (80 km), processes involved in creating the radio beam are either shut down or, more likely, obscured. Some of the gas may be accelerated outward at nearly the speed of light, forming dual particle jets firing in opposite directions. Shock waves within and along the periphery of these jets are a likely source of the bright gamma-ray emission detected by Fermi. || ",

            "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! || ",

            "description": "Did ancient Mars have a thick atmosphere and cloudy skies? Did liquid water flow on its surface? It's hard to imagine either one on the dry, dusty Mars of today. But scientists think the conditions on Mars could have been quite different before the planet started to lose its atmosphere. Exactly how Mars' atmosphere thinned is still being investigated, but there are several possibilities. One is a process called sputtering, a kind of atomic billiards game in which high-energy particles from the sun collide with molecules in the atmosphere and knock them away. NASA's MAVEN mission, scheduled to launch in 2013, will study why and how quickly the atmosphere surrounding Mars turned into thin air. Watch the video to explore the idea that Mars' once-thick atmosphere sputtered away. || ",
