Accurate estimation of the ionosphere is essential for reliable Global Navigation Satellite System (GNSS) positioning, timing, and space weather applications. A key challenge lies in converting slant ...

NASA plans to launch rockets from Kwajalein Atoll to study high-altitude cloud-like structures. The mission, called SEED, begins on June 13 and targets Sporadic-E layers in the ionosphere. Sporadic-E ...

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) ...

An astounding gamma-ray burst, dubbed GRB 221009A, continues to amaze even though it has been more than a year since it was detected. Scientists from Italy have recently published a study that shows ...

Probing a planet’s ionosphere can be all about the timing. Confusion about how many layers of charged particles exist in the Martian atmosphere might be due to what time of day measurements were made.

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 ...

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 ...
