Like Earth, Mars is surrounded by an ionosphere—the part of its upper atmosphere where radiation from the sun knocks ...

Between 50 and 1,000 kilometers above our heads is the ionosphere, a layer of Earth's upper atmosphere consisting of charged particles: ions (atoms that have gained or lost a negatively charged ...

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 ...

The ionosphere is a layer of the atmosphere around 50 to 400 miles above, filled with charged atoms (ions). These ions reflect and refract radio signals, ...

Scientists studying the zone between Earth’s atmosphere and space have spotted unusual X- and C-shaped features that could thwart signals that keep our planet running smoothly.

CU Boulder will conduct a new mission to the ionosphere, ... The reason this layer of the atmosphere is relatively unexplored is because it’s difficult and expensive to keep a spacecraft in orbit.
