State of the Art. When Brainerd Holmes and his NASA associates talk about the C5, the basic tool of their moon mission, they are not bothered at all that it is still unfinished. No F-1 engine has been fired except on a test stand, and the J-2 hydrogen engine (also made by North American) is even farther from flight. None of this worries Holmes. Like most engineers, he is used to forecasting the technical future by figuring what can be accomplished with combinations and modifications of existing equipment. There is nothing in the C-5 Advanced Saturn...
Five of these mighty machines, which are now well into their final reliability tests, will lift each Saturn C-5 off the ground with 7,500,000 Ibs. of thrust. Then a second stage, with five J-2 hydrogen-burning engines (1,000.000 Ibs. total thrust), will take over. Between them, the two stages will be capable of putting a 240,000-lb. payload on an earth orbit 140 miles high. A third stage, with a single J-2 engine, will push 90,000 Ibs. to earth escape velocity and deliver that hefty payload at the moon...
Faint Current. Republic's tiny protons, which are the nuclei of hydrogen atoms, act exactly like small bar magnets. When they are placed in a magnetic field, they tend to line up like a bunch of compass needles. If the magnetic field changes direction, it tries to pull the protons around with it. But protons have a mysterious property called "spin" that makes them react like small spinning wheels. When the magnetic field changes direction, they do not follow obediently. Instead, they resist the turning motion, just as if they were gyro wheels...
Strauss battled for the hydrogen bomb against even stronger opposition. It included the four other members of the AEC, as well as J. Robert Oppenheimer, and most other scientists advising the commission. President Truman took the advice of Strauss (and others) and ordered the bomb to be built. In August 1952, seven months after the first U.S. test, the Russians exploded their first hydrogen bomb. Strauss resigned from the AEC in 1950, but in 1953 he was appointed AEC chairman by Eisenhower and served until...
...view, misses the irony that he became as evasive under congressional grilling as Oppenheimer did when queried about his Communist connections. But Strauss's critics should beware of charging him with arrogance; it was part and parcel of the doggedness that led Strauss to fight for the hydrogen bomb when more adaptable people had their heads in the sand...
