Decades-old Mystery In Earth's Upper Atmosphere Solved
2013-12-18 14:51:49

University of California - Los Angeles New research published in the journal Nature resolves decades of scientific controversy over the origin of the extremely energetic particles known as ultra-relativistic electrons in the Earth's near-space environment and is likely to influence our understanding of planetary magnetospheres throughout the universe. Discovering the processes that control the formation and ultimate loss of these electrons in the Van Allen radiation belts — the rings...

Earth's Van Allen Belts Thrust Particles To Near The Speed Of Light
2013-12-04 14:38:49

Lee Rannals for redOrbit.com - Your Universe Online NASA’s twin Van Allen Probes have led to another new discovery of Earth’s mysterious radiation belts. Researchers used data from the NASA spacecraft to reveal that the high-energy particles populating the Van Allen radiation belts can be accelerated to nearly the speed of light. This finding comes on the heels of a related discovery showing similar particle acceleration but on a microscopic, rather than planetary, scale. “The...

Prairie View A&M And NASA Goddard Collaborate On Radiation Effects Research

NASA When Alvin Boutte presented his graduate work at the 2010 National Society of Black Engineers (NSBE) Aerospace Systems Conference in Los Angeles, Calif., he had no idea that he was about to connect with someone that would be instrumental in guiding his career. In attendance was Anthony Sanders from the Applied Engineering and Technology Directorate (AETD) at NASA’s Goddard Space Flight Center, Greenbelt, Md. The radiation engineering work that Boutte did at Prairie View A&M...

John P. Millis, PhD for redOrbit.com - Your Universe Online [ Watch the Video: Ultra-fast Electrons Explain Third Radiation Belt ] At the dawn of the space race, as two global powers jockeyed for technological supremacy, the ultimate goal was to be the first to send astronauts into space and onto the Moon. While space exploration is rife with challenges, one hurdle in particular brought into question whether man would ever leave low Earth orbit: the Van Allen radiation belts. These...

[ Watch the Video: Earth’s Plasmasphere and the Van Allen Belts ] April Flowers for redOrbit.com - Your Universe Online For more than half a century, the invisible bubble created by Earth's magnetic field - the magnetosphere - has been studied by space missions. The discovery of Earth's radiation belts in 1958 was one of the first scientific breakthroughs made by a spacecraft. The Explorer 1 satellite revealed two concentric, tire-shaped belts of highly energetic (0.1–10 MeV)...

Several Key Discoveries During Van Allen Probes’ First Year
2013-09-01 07:49:38

redOrbit Staff & Wire Reports – Your Universe Online NASA’s twin Van Allen Probes entered their second year of service Friday having already provided a wealth of new information about the layers of energetic charged particles located above our planet. According to the US space agency, data collected by the probes since their August 30, 2012 launch has already led to “several significant discoveries” about the Van Allen radiation belts -- some of which came within the first...

Mysterious Third Radiation Belt Around Earth
2013-06-21 05:07:13

April Flowers for redOrbit.com - Your Universe Online Scientists have long believed that the Van Allen radiation belts, discovered in the Earth’s upper atmosphere in 1958, consisted of two doughnut-shaped rings of highly charged particles. The inner ring is comprised of high-energy electrons and energetic positive ions, and the outer ring of high-energy electrons. This past February in the journal Science, however, a team of scientists reported the surprising discovery of a third,...

NASA’s BARREL Mission Released 20 Balloons To Help Answer Question About Space Weather
2013-05-21 12:07:08

NASA In Antarctica in January, 2013 — the summer at the South Pole — scientists released 20 balloons, each eight stories tall, into the air to help answer an enduring space weather question: when the giant radiation belts surrounding Earth lose material, where do the extra particles actually go? The NASA-funded mission is called BARREL for Balloon Array for Radiation-belt Relativistic Electron Losses and is led by physicist Robyn Millan of Dartmouth College in Hanover, N.H....

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...
