Zhao Receives 2017 Fred L. Scarf Award
Hong Zhao will receive the 2017 Fred L. Scarf Award at the 2017 American Geophysical Union Fall Meeting, to be held 11–15 December in New Orleans, La. This award is given annually to “one honoree in recognition of an outstanding dissertation that contributes directly to solar–planetary science.”
How “Whistling” Plasma Waves Shape Earth’s Radiation Belts
The Van Allen radiation belts surrounding Earth shrink and swell due to plasma waves moving through them, an analysis of satellite data suggests.
How Lightning Creates "Killer Electrons" in Earth's Radiation Belts
New calculations show that lightning-triggered plasma waves in Earth's magnetosphere absorb energy from slow particles and energize electrons to levels that can damage satellites severely.
Global Positioning System Sparks New Data Revolution
Energetic particle data from the Global Positioning System constellation opens avenues for new research.

Where Curiosity Has Taken Us
The Curiosity rover, one of NASA's flagship missions, analyzes Martian geology, geochemistry, climatology, and radiation to assess whether Mars could have supported microbial life.
Human Radio Transmissions Create Barrier to "Killer Electrons"
An interaction between radio waves and the Van Allen radiation belts creates a bubble around the Earth that high-energy electrons can't penetrate.
