...With earth satellites already relegated to the category of "accomplished," Army and Air Force are racing to be first to try the next logical step into space: a shot at the moon. By later summer the Army will fire from Cape Canaveral a Jupiter-C or hopped-up Jupiter that Army Spaceman Wernher von Braun believes will hit the moon. Less optimistic Army missileers expect their missile will either graze the moon-and message back valuable readings on gases around it-or make a lunar orbit. But the Air Force will probably be able to try an orbiting moonshot first...
...exciting new parlor game among physicists is speculating about antimatter in bulk. The earth contains no antimatter because matter and antimatter destroy each other as soon as they meet. Antiparticles are now being created in the laboratory, but the trick of actually building antiatoms is likely to take a long time (TIME, April 21). Meanwhile, those who cherish the laws of symmetry are considering the possibility of distant anti-galaxies in space. Such weird other worlds, balancing galaxies of ordinary matter in the universe, may well exist...
Last week, in the British publication, Nature, Florida State University Physicist Philip J. Wyatt suggested one possible clue: "Of the many craters on the earth known to have been produced by fallen meteors, a few have left no signs of the meteor which caused them, apart from the huge holes created in the earth's crust." Could antimatter possibly have been involved? If so, says Wyatt, "no traces of the meteors would remain, due to the annihilation process." Best example is the huge meteor that blazed over southern Russia on the morning of June 30, 1908. Minutes later...
Test instruments revealed that the third stage of the rocket did not fire, and as a result, the projectile "failed to attain the speed required to send an object into orbit around the earth...
According to a Naval spokesman, the satellite contained an instrument designed to measure the sun's output of X-rays and broadcast its findings to earth. This research would aid in discovering the cause of sun-spot interference on radio waves...
