...voyage to Venus, for example, the space ship would start at 8 miles per second in the direction opposite to the motion of the earth (see diagram) * Since the earth moves at 18½ miles per second, the space ship's net forward motion would be 10½ miles per second (18½; minus 8 miles per sec.). This speed is too slow...
...toward Mars. To reach Mars, the space ship would take off in the same direction as the earth's motion. Its increased speed (8 plus 18½ equals 26½ miles per sec.) would make it spiral outward toward the rendezvous...
Invisible Demon. The obstacle to higher speeds was "compressibility," that invisible, ravening demon formed in the air by the plane's own motion. Long before an airplane itself reaches the speed of sound (770 m.p.h. at 68° F. at sea level), the air, which is speeded up by passing over its surfaces, touches locally that critical velocity. When it does, a "standing sound wave" may set up such vibration that the plane flies to pieces...
...enjoyed an especially good day, gaining 128 yards in 13 carries. Another Gannon effort, a nine-yard off-tackle slant in the fourth period, wound up in the Tiger end zone, but was called back by the officials, who claimed the Varsity had a back illegally in motion. Movies this week should support or quash that decision...
...submitted a request for discussion of "the presence of forces of U.N. member states on the territories of non-enemy countries" to U.N.'s General Assembly (scheduled to meet Oct. 23). Gromyko had made the same request in the Security Council last month. The Council had defeated the motion because of U.S. and British opposition; the U.S. had insisted that all foreign troops, including those on former enemy soil (where the Russians have most of their forces) be discussed...
