Each day, radio signals from key communications and navigation satellites travel freely through a layer of Earth’s atmosphere known as the ionosphere. Floating 50 to 400 miles (80 to 643 kilometers) ...

Fast, precise Global Navigation Satellite System (GNSS) positioning depends on how well models describe the ionosphere, the electrically charged region that bends and delays satellite signals.

The launch of a SpaceX rocket has punched a hole in the planet's ionosphere, leaving a red aurora-like glow in the night sky above California. The Falcon 9 rocket lifted off on Monday from Vandenberg ...

At the Space Weather Workshop in Boulder, Colorado, NASA-funded researchers have released to the general public a “4-D” live model of Earth’s ionosphere. Without leaving home, anyone can fly through ...

A new NASA study focusing on irregularities in Earth’s upper atmosphere may help scientists overcome disruptions in GPS communication. The findings provide an insight into the causes of the disruptive ...

WASHINGTON — A three-stage suborbital sounding rocket on March 3 launched an Air Force Research Laboratory experiment from NASA’s Wallops Flight Facility in Virginia. This was the first sounding ...

A plan to use millions of smartphones to map out real-time variations in Earth’s ionosphere has been tested by researchers in the US. Developed by Brian Williams and colleagues at Google Research in ...

Although Mars is sometimes described as the most Earth-like of all the planets, there are many differences between the two worlds that scientists are trying to understand. One of the less familiar ...

The powerful volcanic eruption in January 2022 created ripple effects throughout the world's atmosphere and oceans. Analysis of the Hunga Tonga eruption shows how signals from the ionosphere could ...

NASA is set to study the Earth's ionosphere during the upcoming total solar eclipse in the US, to better understand the Sun's relationship to the region of the atmosphere where satellites orbit and ...
