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...

Highlights For NASA's Solar Dynamics Observatory Third Year
2013-02-11 14:54:31

NASA [ Watch The Video ] On Feb. 11, 2010, NASA launched an unprecedented solar observatory into space. NASA's Solar Dynamics Observatory (SDO) flew up on an Atlas V rocket, carrying instruments that scientists hoped would revolutionize observations of the sun. If all went according to plan, SDO would provide incredibly high-resolution data of the entire solar disk almost as quickly as once a second. When the science team released its first images in April of 2010, SDO's data...

NASA Renames Radiation Belt Mission

April Flowers for redOrbit.com — Your Universe Online NASA announced the renaming of a recently launched mission to study the radiation belts to the Van Allen Probes in honor of the late James Van Allen, head of the physics department at the University of Iowa. Van Allen discovered the radiation belts encircling Earth in 1958. NASA announced the new name, previously the Radiation Belt Storm Probes (RBSP), at a ceremony at the Johns Hopkins University Applied Physics Laboratory...

Space Radiation Forecasts In Real Time
2012-10-16 14:06:24

Lee Rannals for redOrbit.com - Your Universe Online Astrophysicists have created the first online system for predicting and forecasting the radiation environment in near-Earth, lunar, and Martian space environments. The University of New Hampshire's Space Science Center (SSC) astrophysicists created the near real-time tool to provide critical information for potential manned missions to the moon and Mars. "If we send human beings back to the moon, and especially if we're able to go...

NASA Team Overcoming Image Degradation
2012-10-06 09:34:41

redOrbit Staff & Wire Reports — Your Universe Online A NASA satellite studying the sun saw its view obstructed by Earth for a brief period of time each day throughout much of the month of September. Those eclipses had an unusual effect on the images captured by the probe immediately afterwards, the U.S. space agency revealed on Friday. NASA's Solar Dynamics Observatory (SDO) moved into what is known as its semi-annual eclipse phase from September 6 through September 29,...

Radiation Storm Belt Probes

April Flowers for redOrbit.com - Your Universe Online With the August 30 launch of the Radiation Storm Belt Probes (RSBP), the mission teams at NASA's Kennedy Space Center and Cape Canaveral Air Force Station celebrated a job well done. The mission specialists at the Johns Hopkins Applied Physics Laboratory (APL) were celebrating too, but for many of them at Mission Operations Center (MOC) the job was just beginning. The first 60 days after launch are the commissioning phase of...
