Gold has also demonstrated the possibility that dark regions on the moon are great dust layers, rather than massive flows of lava and has advanced an explanation of their origin. These dust clouds could have been formed, he said, by the constant bombardment of meteors pulverizing the surface...
Wide & Fast. Most laymen assume that the moon is the earth's only satellite, but astronomers make no such easy assumption. One of the planets, Saturn, is surrounded by millions of small objects that form its decorative rings, and the earth may have at least a few such followers. The solar system is littered with such homeless rubbish as asteroids, meteors and comets, and some of these may have settled into permanent orbits around the steady earth...
Working at Lowell Observatory, Flagstaff, Ariz., Dr. Tombaugh used some fancy apparatus: a Schmidt telescopic camera so sensitive that it could photograph a tennis ball, half-lit by the sun, 1,000 miles away, or a V-2 rocket at the distance of the moon. It covered a 13° field, 26 times the apparent diameter of the full moon, and a complicated driving mechanism swung it across the sky, fast for nearby satellites, slower for satellites farther away. On its plates the stars showed as streaks. A satellite, if one had been found, would have shown...
Excessive flight-time has worried spacemen ever since Jules Verne's "voyage" to the moon in a habitable projectile (see cut). Today's rocket speeds are good for trips in the solar system, but for interstellar voyages they are hopelessly slow. Conservative space enthusiasts accept the speed of light as the absolute speed limit in the material universe, and they know that even at this ultimate speed a spaceship can reach only nearby stars within a human generation. This seems to put a limit on man's interstellar mobility. But some optimistic scientists see hope in "time...
