A recent celebration of the 60th anniversary of the launch of Explorer 1 reflected on the incredible progress and scientific insights from this and subsequent space missions.Read More »
High above Earth’s surface, air temperatures occasionally increase suddenly, producing widespread effects on weather, air chemistry, and telecommunications.Read More »Space Science & Space Physics
Scientists are blending output from multi-year model runs to improve temperature forecasts in regions where satellites experience “drag,” in the hopes of avoiding future spacecraft collisions.Read More »Space Science & Space Physics
Imperfect knowledge of high-latitude forcing of the coupled ionosphere-theremosphere system translates into uncertainty in the low-latitude and midlatitude response to a geomagnetic storm.Read More »Space Science & Space Physics
Most fast coronal mass ejections will be decelerated into ambient solar wind quickly in the inner heliosphere, but some of them continue the deceleration with an even larger amplitude beyond 1 AU.Read More »Space Science & Space Physics
A new model of geomagnetically induced currents revisits how space weather damaged a New Zealand grid transformer in 2001, and shows how much worse it could be in a space weather superstorm.Read More »Space Science & Space Physics
Space weather forecasting is benefiting, and can benefit much further, from concepts and tools already developed by the global meteorological community.Read More »Atmospheric Sciences
To help mitigate magnetic storm interference on electric power grid operations, extreme-value geoelectric fields have been mapped across the mid-Atlantic United States.Read More »Planetary Sciences
When it comes to Saturn’s space environment, summer wins over winter in controlling the periodic flows of electrically charged particles and magnetic fields.Read More »
