...presumably U.S. rocketmen are making progress. To judge from the photograph (the only information released), the Aerobee is much slimmer and lighter than the V2. It is probably an experimental model built, not to make any impressive altitude records, but to test improvements in motive power and control...
...good look at the "undreamed vistas" of space, Dr. Zwicky plans to use three kinds of projectiles: 1) large primary rockets, such as the V2, which will carry scientific instruments to the upper parts of the earth's atmosphere; 2) secondary rockets, which will be launched from the primary rockets to a height of 650 miles, and will also carry recording instruments; 3) flying missiles, "capable of flying off into interplanetary space, never to return," which will be hurled free at a speed of over seven miles a second...
Slimmer, Steadier. The Navy says with a straight face that the Neptune is only a peaceful research project. Its specifications give it a warlike look. It will be 45 ft. long-one foot shorter than the German V2, which is now considered obsolescent. It will be slimmer (32 inches in diameter instead of 65) and will weigh about six tons fully loaded, instead of the V-2's 14 tons...
...planned, the Neptune will burn the same fuels as the V2: alcohol and liquid oxygen. It will also carry hydrogen peroxide, which suggests that, like the V2, it will have a steam-driven pump to rush the fuel into the combustion chamber...
...miles before its momentum is exhausted. Its greatest speed coming down will be 8,200 ft. per second (4,833 m.p.h.). Maximum pay load: one ton. The Navy does not estimate publicly how far the rocket will travel horizontally. Since it rises nearly twice as high as the V2, it may be expected to exceed the V-2's 230-mile range...
