The article discusses Project Argus, a series of tests in which the explosion of three low-yield nuclear bombs at high altitude over the South Pacific confirmed the theory that radiation follows the lines of force of the earth's magnetic field. The findings of the U.S. Army's Explorer IV satellite will be publicly announced on April 27-29, 1959 at National Science Foundation's annual meetings. The radiation emitted by Project Argus is sucked into one of the Van Allen belts in space.

The article reports on the structure and shape of Van Allen radiation belts based on the recent data from earth satellites and rockets in the U.S. Data from heavily instrumented earth satellites Explorer VII indicate that the northern rim of the outer belt passes over the northern part of the country. The energy distribution confirms the theory that the particles in the outer belt originate in the sun, rather than from the decay of neutrons liberated by cosmic rays.

Answers questions to the validity of the United States lunar landing. Inquiry to the survival of the astronauts after passing thru the Van Allen Radiation belts; Clarification of the absence of a blast crater under the Apollo 12 Lunar Lander; Contradiction of the flapping of flags in an airless lunar space.

The article reports that scientists investigating the Van Allen radiation belts revealed unexpected findings 96 days after launching two space probes and only 30 days after they became fully operational. According to the author, mission scientists at the annual meeting of the American Geophysical Union found that the belts are far more active and potentially dangerous than had been previously known.

The article discusses developments and trends in the field of astrodynamics for 2012. The National Aeronautics and Space Administration's (NASA) gravity recovery and interior laboratory (GRAIL) twin orbiters Ebb and Flow arrived at the Moon to mapped lunar gravity. NASA also launched the Radiation Belt Storm Probes to study the Van Allen radiation belt. The 13-ton Phobos-Grunt spacecraft was launched aboard a Zenit launcher but was trapped in an undesirable low Earth orbit.
