First Multi-Decade Simulation of the Earth’s Radiation Belt
A new simulation of the Earth’s electron radiation belts captures large-scale variations over nearly three solar cycles, and replicates primary cyclical features and extreme behaviors.
Hello, Goodbye: First Interplanetary CubeSats Zip Past Mars
The InSight lander safely arrived on Mars early last week. Two tiny spacecraft made up part of its communications array and transmitted landing data back to Earth.
Seeing Waves: GNSS Tracking of Waves in the Upper Atmosphere
Dense GNSS networks enable scientists to track large-scale waves traveling through the upper atmosphere, away from sources in the auroral zone and the day/night terminator.
Wireless Frequency Sharing May Impede Weather Satellite Signals
The delivery of weather satellite imagery is reliable today, but will it stay that way in the future?
Double Threat to Solar Panels in Space
Protons accelerated in solar storms and electrons accelerated in geospace storms can reduce space mission lifetimes. What is the likelihood of extreme events during geospace storms?
Global Ice Monitoring Satellite to Launch as Early as This Week
The soon-to-launch satellite will measure the height and thickness of sea ice, glaciers, ice sheets, and permafrost around the world to an unprecedentedly high precision.
Scientists Meet to Review Preparations for Satellite Launch
Center for Satellite Applications and Research JPSS 2017 Annual Science Team Meeting; College Park, Maryland, 14–18 August 2017
Illegal Seafood Supply Chains Can Now Be Tracked by Satellite
Researchers pinpoint more than 10,000 likely transfers of catches between fishing vessels and cargo ships at sea. Knowing where these transfers occur can help officials crack down on illegal activity.
Forecasting the Threat from the Sun
Ensemble techniques are opening a path toward space weather forecasts that give deeper understanding of the risk posed by each solar storm that approaches our planet.
