WASHINGTON, Aug. 29, 2014 /PRNewswire-USNewswire/ -- NASA's twin Van Allen Probes will celebrate on Saturday two years of studying the sun's influence on our planet and near-Earth space. The probes, shortly after launch in August 2012, discovered a third radiation belt around Earth when only two had previously been detected. http://photos.prnewswire.com/prnvar/20081007/38461LOGO The radiation belts are layers of energetic charged particles held in place by the magnetic field surrounding...

Karen C. Fox, NASA's Goddard Space Flight Center One of the great, unanswered questions for space weather scientists is just what creates two gigantic donuts of radiation surrounding Earth, called the Van Allen radiation belts. Recent data from the Van Allen Probes -- two nearly identical spacecraft that launched in 2012 -- address this question. The inner Van Allen radiation belt is fairly stable, but the outer one changes shape, size and composition in ways that scientists don't yet...

NASA All the superlatives associated with Orion's first mission this year – farthest a spacecraft for humans has gone in 40 years, largest heat shield, safest vehicle ever built – can be dazzling, no doubt. But the reason engineers are chomping at the bit for Orion's first mission is the promise of crucial flight test data that can be applied to the design for future missions.  Orion only has two flight test opportunities before astronauts climb aboard for the first crewed mission in...

NASA's BARREL Returns From Antarctica

Karen C. Fox, NASA Three months, 20 balloons, and one very successful campaign: The team for NASA's BARREL – short for Balloon Array for Radiation belt Relativistic Electron Losses -- mission returned from Antarctica in March 2014. In a new NASA Flickr gallery, the team shared their images from weeks of work in the constant sun of the South Pole summer. BARREL's job is to improve our understanding of the mysterious Van Allen belts, two gigantic doughnuts of radiation that surround...

[ Watch The Video: BARREL Team Launching 20 Balloons ] Karen C. Fox - NASA's Goddard Space Flight Center, Greenbelt, Md. In the bright light of Antarctica's summer sun, a NASA mission launched its first 18 science balloons between Dec. 27, 2013, and Feb. 2, 2014. BARREL, or the Balloon Array for Radiation belt Relativistic Electron Losses, plans to launch 20 balloons in total to help unravel the mysterious radiation belts, two gigantic donuts of particles that surround Earth....

Balloon Campaign In Antarctica Begins Its Second Year
2014-01-03 07:46:36

NASA The second year of an unprecedented balloon campaign in Antarctica has just begun. The NASA-funded mission – called the Balloon Array for Radiation belt Relativistic Electron Losses, or BARREL – is led by Dartmouth College in Hanover, N.H. The mission is unique, as it relies not on one gigantic balloon, but on many smaller ones, 20 in total. BARREL's job is to help unravel the mysterious radiation belts, two gigantic donuts of particles that surround Earth. The mission works in...

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...
