Future spacecraft designed to cruise to the moon or Mars will have even more complicated control systems, on-course propulsion that can be turned on and off, and telescopes to track the earth, the sun and the target. If they intend to rendezvous with other spacecraft, they will probably carry...
Measuring the distance to Mars or other such far-out planets is far trickier; they are well beyond the useful range of available radar. Astronomers calculate the interplanetary distance by observing the time it takes for Mars to complete one orbit around the sun and comparing that time with the...
Artificial Planet. Trouble is, that the astronomical unit is known with even greater inaccuracy than the speed of light. As Mars curves around its orbit, its measured distance from the earth may be as much as 2,000 miles in error. Dr. Lowther hopes to clear up this unhappy situation...
The Radcliffe Chorale Society was indeed brave in taking on the Verses From the Book of Ruth composed by Claudio Spies in 1959. What mars the work is its stilted literalness, and the performance added to this monotony. Narrator Lee Bradley did not tell us a story: she just read...
For years scholars have known about this dating system, but tracing astronomical motions backward for more than 2,000 years is forbiddingly time consuming for slow-working human brains. So Mathematician Bryant Tuckerman of IBM got time on a 704 computer. In 40 hours of electronic calculation the 704 riffled...
