Latest Ionosphere Stories
Way up in the Earth’s atmosphere is a layer of charged particles called the ionosphere, which plays a crucial role in the transmission of radio and other signals.
A NASA-funded sounding rocket mission will launch from an atoll in the Pacific in the next few weeks to help scientists better understand and predict the electrical storms in Earth's upper atmosphere. These storms can interfere with satellite communication and global positioning signals.
NASA has awarded the University of California, Berkeley, up to $200 million to build a satellite to determine how Earth’s weather affects weather at the edge of space, in hopes of improving forecasts of extreme “space weather” that can disrupt global positioning satellites (GPS) and radio communications.
On April 16, 2008, a suite of NASA instruments was launched into space to study a unique region of Earth’s upper atmosphere: the electrically charged region called the ionosphere.
U.S. Naval Research Laboratory research physicists and engineers from the Plasma Physics Division, working at the High-frequency Active Auroral Research Program (HAARP) transmitter facility, Gakona, Alaska, successfully produced a sustained high density plasma cloud in Earth's upper atmosphere.
The world was on edge earlier this month when North Korea detonated an underground nuclear explosion meant to showcase to the world community the abilities of this beleaguered nation.
When talking about lightning, appearances of different lightning which occur along with thunderstorms will emerge in the minds of the people and these lightning occur in the troposphere.
To study a poorly understood phenomenon known as charge exchange, NASA scientists teamed up to build NASA's first wide-field-of-view soft X-ray camera using "lobster eye" technology.
At the very edges of the Earth’s atmosphere, where the Earth’s magnetic field begins, solar radiation strips electrons from the tenuous gas that is slowly leaking into space.
Arecibo Observatory -- The Arecibo Observatory is part of the National Astronomy and Ionosphere Center (NAIC), a national research center operated by Cornell University under a cooperative agreement with the National Science Foundation (NSF). The NSF is an independent federal agency whose aim is to promote scientific and engineering progress in the United States. NSF funds research and education in most fields of science and engineering. Additional support is provided by the National...
- A pivoted catch designed to fall into a notch on a ratchet wheel so as to allow movement in only one direction (e.g. on a windlass or in a clock mechanism), or alternatively to move the wheel in one direction.
