Geotail Mission Celebrates 20th Anniversary
2012-07-28 08:59:52

Lee Rannals for redOrbit.com - Your Universe Online Twenty years ago, the United States relationship with Japan showed just how restored it was since the second world war, as the two countries' space agencies launched a joint mission together. The Geotail mission launched into space aboard a Delta II launch vehicle 20 years ago from this week, kick-starting a set of coordinated missions known as the International Solar Terrestrial Physics (ISTP) project. ISTP studied the magnetic...

Plasma Waves Move Faster Than Shockwaves

Lawrence LeBlond for redOrbit.com - Your Universe Online The Sun and the dynamic space weather system that envelops the Earth are what researchers are trying to get a better understanding of with the help of Heliophysics nuggets -- collections of early scientific results, new research techniques and instrument updates. More than 99 percent of the matter found in the universe resembles nothing like what we have here on Earth, according to scientists from NASA´s Goddard Space Flight...

New Research Better Understands Lunar Swirls
2012-07-19 13:42:14

Lee Rannals for redOrbit.com - Your Universe Online A study of "lunar swirls" on the moon may eventually lead to new developments in engineering to help protect astronauts in space. During the Apollo missions, scientists realized that lunar swirls were associated with localized magnetic fields in the lunar crust. NASA's Lunar Prospector focused on the regions and identified magnetic anomalies that had created fully formed miniature "magnetospheres" similar to what the Earth's...

NASA Mission Set To Study Plasma
2012-07-18 14:36:34

[ Watch the Video ] Lee Rannals for redOrbit.com - Your Universe Online A new NASA mission set to launch in August 2012 called the Radiation Belt Storm Probes (RBSP) will keep its eye focused on plasma. Ninety-nine percent of the universe is made of this electrified gas, but when it comes to the Earth it is more absent than present. There are two giant donuts of plasma surrounding Earth trapped within a region known as the Van Allen Radiation Belts. The belts are close to...

Engineers and scientists at the Lockheed Martin [NYSE: LMT] Space Systems Advanced Technology Center (ATC) have completed delivery of key hardware subsystems for NASA´s Magnetosphereic Multiscale mission (MMS). The delivery comprised four flight subsystems and one flight spare unit. The prime contractor Southwest Research Institute (SWRI) partnered with Lockheed Martin to develop and build the Hot Plasma Composition Analyzer (HPCA) as part of the MMS instrument suite. When it launches...

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...

Enceladus Plume Highlights 'Dusty Plasma'
2012-06-04 07:20:05

Recent findings from NASA's Cassini mission reveal that Saturn's geyser moon Enceladus provides a special laboratory for watching unusual behavior of plasma, or hot ionized gas. In these recent findings, some Cassini scientists think they have observed "dusty plasma," a condition theorized but not previously observed on site, near Enceladus. Data from Cassini's fields and particles instruments also show that the usual "heavy" and "light" species of charged particles in normal plasma are...

MESSENGER scientists have concluded that waves driven by the Kelvin-Helmholtz (KH) instability play a key role in driving Mercury's magnetosphere. In a paper published recently in the Journal of Geophysical Research, the team reports on frequent detections of such waves at the outer edge of the innermost planet's magnetosphere. The paper was selected as an Editor's Highlight by the journal editor, and its findings are scheduled to be featured as a Research Highlight in Eos, the weekly...

NASA Satellite Captures Spectacular Solar Eruption
2012-04-17 06:43:52

[ Watch the Video ] A NASA satellite yesterday captured spectacular images and video of a massive solar flare erupting from the eastern side of the Sun. The M1.7 (medium intensity) class solar “prominence eruption” produced a coronal mass ejection (CME) that was captured by NASA´s Solar Dynamics Observatory (SDO). The event occurred at 1:45 p.m. EDT on April 16, 2012. The ejection, impressive as it was, was only a moderate event by astronomy standards. Such flares...

Hannes Olof Gösta Alfvén (May 30, 1908 - April 2, 1995) was a Swedish plasma physicist born in Norrköping, Sweden. Alfvén received his PhD from the University of Uppsala in 1934. His thesis was titled "Investigations of the Ultra-short Electromagnetic Waves." He was originally trained as an electrical power engineer and later moved on to research and teaching in the fields of plasma physics. Alfvén made many contributions to plasma physics, including theories describing the...

Ring Current
2004-10-19 04:45:44

Ring Current -- A ring current is an electric current carried by charged particles trapped in a planet's magnetosphere. It is caused by the longitudinal drift of energetic (10-200 keV) particles. Earth's Ring Current Earth's ring current is responsible for geomagnetic storms. The ring current system consists of a band, at a distance of 3-5 RE(1), which lies in the equatorial plane and circulates clockwise around the Earth (when viewed from the north). The particles of this region...

Heliopause -- The heliopause is the boundary where our Sun's solar wind is stopped by the interstellar medium. The solar wind blows a "bubble" in the interstellar medium (the rareified hydrogen and helium gas that permeates the galaxy). The point where the solar wind's strength is no longer great enough to push back the interstellar medium is known as the heliopause, and is often considered to be the outer "border" of the solar system. The distance to the heliopause is not precisely...

Aurora -- The Polar Aurora are natural displays of light in the sky that can be seen with the unaided eye only at night. An auroral display in the Northern Hemisphere is called the aurora borealis, or the northern lights; in the Southern Hemisphere it is called the aurora australis. Auroras are the most visible effect of the sun's activity on the earth's atmosphere. The beautiful and often eerie curtains of light in the night time sky have been observed by people for millennia. An aurora...
