Understanding Saturn’s space environment: Looking backward, looking forwards

Editor’s Highlight—   With NASA’s Cassini Mission to Saturn now complete, this paper shows how the Cassini Plasma Spectrometer (CAPS) instrument contributed to our understanding of the Saturn space environment. The authors have used forward modeling to produce a new moments dataset that could be useful.... more

Statistical properties of solar wind reconnection exhausts

Editor’s Highlight— The analysis presented in this paper shows for the first time that the amount of increase in plasma density and ion temperature across solar wind exhausts depends on both the external plasma beta and the magnitude of the background guide magnetic field. This is an important new result.... more

How “Whistling” Plasma Waves Shape Earth’s Radiation Belts

Mark Zastrow, Freelance Writer

From Research Spotlights— The Van Allen radiation belts surrounding Earth shrink and swell due to plasma waves moving through them, an analysis of satellite data suggests. The defining scientific discovery of the early space age was the Van Allen radiation belts: regions of hazardous, highly.... more

New Explanation for "Meandering" Electrons Orbiting Earth

Mark Zastrow, Freelance Writer

From Research Spotlights— A new study proposes a simpler theory to explain a class of electrons zipping around the Earth, propelled by magnetic explosions. In 2015, NASA launched a fleet of four spacecraft that seek out the strange physics that happen at the fringes of Earth's magnetic field..... more

Spacecraft Returns Its First Data on Martian Solar Irradiance

Sarah Stanley, Freelance Writer

From Research Spotlights— Scientists demonstrate the capabilities and limitations of the mathematical model used to calculate solar irradiance using measurements from NASA’s Mars Atmosphere and Volatile Evolution (MAVEN).  Ancient riverbeds, mineral deposits, and abundant additional evidence.... more

Untangling Uranus’s topsy-turvy magnetosphere

BLOG— New observations of Uranus being buffeted by shock waves from the sun have revealed auroral activity and fresh clues to the workings of the seventh planet’s unusual magnetosphere, the region of space dominated by its magnetic field. Mapping out the magnetospheres of planets like Earth, Jupiter.... more
