Gonzalo: A book of First Class stamps http://bbgrocerymeatdeli.com/web-specials/ doxycycline order The radiation belts, named after their discoverer, James Van Allen, are comprised of an outer region of extremely high-energy electrons, with an inner region of energetic protons and electrons. The belts have been studied extensively since the dawn of the Space Age, because the high-energy particles in the outer ring can cripple or disrupt spacecraft. Long-term observation of the belts have hinted that the belts can act as efficient and powerful particle accelerators; recent observations by the Van Allen Probes (formerly known as the Radiation Belt Storm Probes)—a pair of spacecraft launched in August 2012—now seem to confirm this.
