Major Review Passed For NASA Mission To Study Magnetic Explosions
2012-09-06 07:20:05

On August 31, 2012 , NASA's Magnetospheric Multiscale (MMS) mission proved it was ready for its next steps by passing what's called a Systems Integration Review (SIR), which deems a mission ready to integrate instruments onto the spacecraft. The MMS mission is due to launch in late 2014. It will observe a mysterious process called magnetic reconnection, which creates explosive bursts of energy and which powers a variety of space phenomena from the aurora to giant eruptions of radiation on...

Lee Rannals for redOrbit.com - Your Universe Online Scientists are warning that power grids, communications and satellites could be knocked out by a massive solar storm within the next two years. The sun will be reaching its peak in its 10-year solar activity cycle, putting the Earth at a greater risk from solar storms. During this peak, scientists say there is a heightened risk that a solar storm could knock out the communication systems that we rely on. "Governments are taking...

Cluster Examines Thin Current Sheets In The Magnetosphere
2012-08-02 05:08:15

April Flowers for redOrbit.com - Your Universe Online The Universe is filled with plasma, a charged gas consisting of ions and electrons. Thin sheets, or boundaries, with currents separate large plasma regions. These boundaries are where most of the exciting action in space happens. Scientists at the Swedish Institute of Space Physics (IRF) have measured the fundamental properties of one of the waves mixing and accelerating plasmas within these sheets. These thin current sheets are...

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...

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...

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...

Van Allen Radiation Belt -- The Van Allen radiation belt is a torus of energetic charged particles around Earth, trapped by Earth's magnetic field. The presence of a radiation belt had been theorized prior to the Space Age and the belt's presence was confirmed by the Explorer I on January 31, 1958 and Explorer III missions, under Doctor James Van Allen. The trapped radiation was first mapped out by Explorer IV and Pioneer III. Qualitatively, it is useful to view this belt as consisting...

Solar Wind -- Solar wind, a stream of particles (mostly high-energy protons ~ 500 Kev) that is continually ejected from the surface of the Sun. The composition of this plasma is identical to the Sun's corona, 73% hydrogen and 25% helium with the remainder as trace impurities, and is ionized. Near Earth, the velocity of the solar wind varies from 200km/s-889km/s. The average is 450 km/s. Approximately 3000 tons of material is lost from the Sun every hour as solar wind. Since solar...

Solar Flare -- A solar flare is a violent eruption that explodes from a star's photosphere with energies equivalent to tens of millions of hydrogen bombs. Solar flares from the Sun send out a streams of highly energetic solar wind that can present a radiation hazard to spacecraft outside of planetary magnetospheres and can disrupt radio signals on Earth. Solar flares were first observed on the Sun in 1859 by English astronomer Richard Carrington. They have also been observed to...
