...From the earth's surface, space has long seemed hardly more than an emptiness between the earth and the stars. But space probers have found that it has a geography as complex as the maze of pipes and conduits under a downtown city street. Last week the Army Signal Research and Development Laboratory at Fort Monmouth, N.J. reported the discovery of a new and unsuspected duct of ionized particles that leads magnetic waves around the earth...

When the rocket-launched atom bombs of Project Argus were exploded last year 300 miles above the South Atlantic (TIME, March 30), most of the ionized particles the explosions created were picked up by the earth's magnetic field and lofted in arching curves around the earth in a man-made imitation of the Van Allen radiation belts. This effect was expected and was duly observed by U.S. scientists. But a team of the Army's Fort Monmouth men, led by Dr. Hans A. Bomke, was quietly watching for subtler effects. To pick up the faint traces they...

...thin, high, outer fringe of the atmosphere, the Fort Monmouth men explained, the atoms of gas are ionized by solar ultraviolet light into positively charged nuclei and negative electrons. Theory suggested that at a certain altitude above the earth this charged plasma should have a sort of elasticity that would permit hydromagnetic waves to pass along it, rather like mechanical waves traveling along a coil spring. The Fort Monmouth scientists found that the Argus explosions started just such waves in a layer of plasma about 1,500 miles high. The waves were about 1,000 miles long, and they traveled...

...scientists followed the waves halfway round the earth and then lost track of them. But since the Argus tests, the Fort Monmouth team has noticed other waves that travel in the same high duct of plasma, apparently started by electrified particles slamming in from the sun. The Signal Corps is continuing to study its newfound duct. But when its scientists are asked whether they hope to find practical uses in communication, their military chaperons stop the conversation...
