ESA Finds High-Energy Particles Charged In Polar Cusps
2012-06-08 04:46:56

Data gathered by several European Space Agency (ESA) spacecraft suggests that high-energy particles which fill cavities within the Earth's magnetic field are accelerated locally within the cusps themselves as they cross through areas characterized by different electric potential, the organization announced earlier this week. In a Tuesday announcement, the ESA said that the information, which was gathered during the Cluster mission in February 2003, shows that the particles are accelerated...

Researchers Document Auroral Turbulence Using Nanosatellite Radar Receiver
2012-03-23 07:20:41

Researchers from SRI International and the University of Michigan have taken the first-ever measurement of naturally occurring auroral turbulence recorded using a nanosatellite radar receiver. The research was done with support from the National Science Foundation (NSF) and NASA's Educational Launch of Nanosatellites (ELaNa) Initiative. The distinctive radar echoes recorded on March 8 were taken with the Radio Aurora Explorer (RAX) CubeSat. The RAX nanonsatellite measured turbulence over...

Organic solar cells may be a step closer to market because of measurements taken at the National Institute of Standards and Technology (NIST) and the U.S. Naval Research Laboratory (NRL), where a team of scientists has developed a better fundamental understanding of how to optimize the cells' performance. Prototype solar cells made of organic materials currently lag far behind conventional silicon-based photovoltaic cells in terms of electricity output. But if even reasonably efficient...

On Saturday, a team of U.S. researchers launched a two-stage rocket containing some 500 pounds worth of instruments through an aurora, with the hopes that they will be able to learn more about how the northern lights are created and about the complex relationship between the Earth and the Sun. According to Fairbanks Daily News-Miner Reporter Sam Friedman, the 46-foot NASA rocket was launched from the Poker Flat Research Range in Fairbanks, Alaska at 8:41pm on February 18. The rocket...

Russia Blames HAARP Transmitter For Phobos-Grunt Failure
2011-12-15 12:32:37

After abandoning efforts to save its Martian moon probe, Phobos-Grunt, that has been stranded in Earth´s orbit since early November, Russia is now focusing on where the blame lies for the expensive mishap. The accused: Alaska´s High-frequency Active Auroral Research Program (HAARP) transmitter. Phobos-Grunt, now considered a 7.5 ton heap of space debris, is expected to plunge back to Earth around January 9, two months after it became stranded, according to Russian space agency,...

Proba2-1-HR
2011-12-03 12:24:23

Researchers gathered for European Space Weather Week have been presented with the latest results from ESA´s own space weather station: the Proba-2 microsatellite. The unpredictably stormy Sun drives space weather: surges of charged particles can damage satellites, impede space-based services and affect terrestrial power networks. Less than a cubic metre, Proba-2 was launched on 2 November 2009 as a technology demonstrator but is now working as a science mission, having...

Image 1 - Lightning-Made Waves Leaking Into Space From Earth's Atmosphere
2011-11-29 10:08:34

[ Watch the Video ] NASA said on Monday that scientists have discovered lightning-made waves in Earth's atmosphere that leaked into space. The space agency's Vector Electric Field Instrument (VEFI) aboard the U.S. Air Force's Communications/Navigation Outage Forecast System (C/NOFS) satellite has detected Schumann resonance from space. Schumann resonance happens if waves are just the right wavelength from lightning, combining and increasing in strength to create a repeating...

Mystery of the Lunar Ionosphere
2011-11-15 10:19:36

[ Watch the Video ] Lunar researchers have been struggling with the mystery for years, and they may have finally found a solution. But first, what is an ionosphere? Every terrestrial planet with an atmosphere has one.  High above the planet´s rocky surface where the atmosphere meets the vacuum of space, ultraviolet rays from the sun break apart atoms of air.  This creates a layer of ionized gas--an "ionosphere." Here on Earth, the ionosphere has a big impact on...

FASTSAT Paints Detailed View Of Region Near Earth
2011-11-15 04:17:57

Space around Earth is anything but a barren vacuum. The area seethes with electric and magnetic fields that change constantly. Charged particles flow through, moving energy around, creating electric currents, and producing the aurora. Many of these particles stream in from the solar wind, starting out 93 million miles away on the surface of the sun. But some areas are dominated by particles of a more local source: Earth's atmosphere. These are the particles being watched by FASTSAT's...

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...
