...meteors, performed magnificently, leaving an ionized trail at each night passage. The trail reflected the time signal strongly for as much as a minute. The bursts of reflected waves came from just the right places and at just the right times to fit the satellite's slowly shifting orbit...
...plan carefully what it feels can be accomplished in the next 25 years. Its scientists have already placed on Washington desks a four-phase plan that would put manned satellites into space within five years. An improved Atlas would, by mid-1959, put a reconnaissance satellite into orbit 350 miles up to transmit televised images to earth. This would be followed by a series of satellites that, by early 1960, would keep a 24-hour watch on every part of the earth's surface. By late 1960-provided the Government adopts the plan soon-Atlas would push a manned...

...Their apparent aim is to achieve a reputation for disinterestedness, their hope that eventually the underdeveloped countries will look to them for leadership and help. The economic bridgeheads, once established, can be expanded into an economic dependence that can eventually bind a country as firmly into the Communist orbit as any political pledge...
...Smithsonian scientists calculated the density of the upper atmosphere by studying the gradually shrinking orbit of Sputnik I. Under the old theory, Sputnik I should stay up for about 27 months before aerodynamic drag and gravity pull it down into air dense enough to destroy it by the heat of friction. But now the Smithsonian scientists think that the moon will set for good after only 3½ months, flare into destruction sometime around the middle of January...
