NASA's CINDI Celebrating Fifth Anniversary
2013-04-15 15:10:13

NASA 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. The instruments, known collectively as CINDI (Coupled Ion-Neutral Dynamics Investigation), fly aboard an Air Force Research Laboratory satellite called C/NOFS (Communications/Navigation Outage Forecasting System) to study this region that hovers some 60 to 400 miles above Earth. The ionosphere is...

Densest Artificial Ionospheric Plasma Clouds Produced Using HAARP
2013-02-26 10:34:33

U.S. Naval Research Laboratory 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. "Previous artificial plasma density clouds have lifetimes of only ten minutes or less," said Paul Bernhardt, Ph.D., NRL Space Use and Plasma Section. "This higher...

Scientists Use Radio Telescopes And GPS To Monitor Nuclear Tests
2013-02-20 19:02:30

Alan McStravick for redOrbit.com — Your Universe Online The world was on edge earlier this month when North Korea detonated an underground nuclear explosion (UNE) meant to showcase to the world community the abilities of this beleaguered nation. In a recent story published in The Guardian, reports surfaced North Korea is planning two additional nuclear tests just this year. UNEs were once commonplace, giving the testing nation the knowledge surrounding their nuclear capability. The...

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. However, in addition to lightning in the troposphere, there are kinds of lightning discharges which occur above the thunderstorms. Up to now, lightning discharges above storms include sprite, elves (Emissions of Light and VLF perturbation due to EMP Sources, elves), Blue jet and Gigantic jet etc, and all of...

April Flowers for redOrbit.com - Your Universe Online To study charge exchange, a poorly understood phenomenon that occurs when the solar wind collides with Earth's exosphere and neutral gas in interplanetary space, three NASA scientists teamed up to develop and demonstrate NASA's first wide-field-of-view soft X-ray camera. It is rare to have researchers from such diverse disciplines as heliophysics, astrophysics and planetary science teaming up, but that's exactly what happened at...

Venus Caught Looking Like A Comet
2013-01-30 04:35:17

[ Watch the Video: What is Venus? ] John P. Millis, Ph.D. for redOrbit.com — Your Universe Online 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. This region, known as the ionosphere is famously responsible for allowing terrestrial radio transmissions over great distances. During World War II, for example, radio operators would...

Solar Winds Affect Earth's Magnetosphere
2012-08-01 13:04:29

April Flowers for redOrbit.com — Your Universe Online Weather has always affected our lives, but we are increasingly reliant on technology that can be disrupted by space weather. Geomagnetic storms, which are major disturbances of the magnetosphere, cause high altitude flights to be rerouted, costing many thousands of dollars per flight; cause GPS errors of up to 151 feet; and affect the International Space Station and satellites. Geomagnetic storms and other space weather...

Jansky Very Large Array Achieves First Light
2012-07-22 07:59:27

redOrbit Staff & Wire Reports - Your Universe Online Researchers with the U.S. Naval Research Laboratory (NRL) and the National Radio Astronomy Observatory (NRAO) in New Mexico announced Friday that they had successfully achieved "first light" at low frequencies using the Jansky Very Large Array (JVLA) radio astronomy telescope. Using five of the JVLA's 27 230-ton, 25-meter diameter very high-frequency (VHF) dish antennas, NRAO astronomer Dr. Frazer Owen was able to map the radio...

Tiny 'Firefly' Satellite Used To Flash Straight Into Lightning and Thunderstorms
2012-07-20 15:50:45

'CubeSat' will help solve mysteries of terrestrial gamma ray flashes, 1,000 times more powerful than 'northern lights' Imagine a fully-instrumented satellite the size of a half-gallon milk carton. Then imagine that milk carton whirling in space, catching never-before-seen glimpses of processes thought to be linked to lightning. The little satellite that could is a CubeSat called Firefly, and it's on a countdown to launch next year. CubeSats, named for the roughly four-inch-cubed...

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...
