...times a year, Marsden said, "we get telegrams which lead nowhere. Last week, one man claimed to have discover- ed a colossal nova, but it turned out to be the planet Saturn. It usually taken a fey seconds of observation to find the false alarm...
Liquid hydrogen is the most effective rocket fuel ever developed. Some 40% more powerful than the kerosene fuel used in the Saturn booster, it will place the Apollo spacecraft in earth orbit, then be used again in the same flight to hurl the spaceship toward the moon. The trouble is, its virtues are not bought cheaply. Its extreme volatility and the - 423° F. temperature necessary to keep it in liquid form make it difficult to deal with both on the ground and in space. NASA spacemen had theorized that once weightless in orbit, liquid hydrogen would scatter around...
...question remained: would the theory prove practical in space? To find out, NASA engineers installed television cameras inside the SIV B's hydrogen fuel tank. All through the acceleration of blastoff, and while the Saturn I first stage was pushing the SIV B aloft, the TV screens at the Houston control center showed the liquid hydrogen settled and calm on the bottom of the tank, its surface barely rippling. After the first stage had dropped away and the SIV B's engine was fired to insert it into orbit, the level of the liquid hydrogen could be seen...
...speeds varying from I/10th to 1 m.p.h., the crawler inched along its steel treads while its 16-man crew co ordinated its activities through an intercom system. The angle of the crawler platform was constantly adjusted so that Saturn would never tilt more than 4 min. of 1° from true vertical. After negotiating a curve and a 3° slope leading to the launch pad, the crawler successfully delivered its cargo and workmen began bolting the umbilical tower and the Saturn 5 to the pad, getting the huge pair ready to train both ground crews and astronauts. When...
Shortly after dawn on the day of the rollout, a 456-ft.-high door in the Vertical Assembly Building slid slowly open. Inside the eight-acre, 52-story structure, the locomotive-size diesel engines of a giant crawler-transporter thundered into life. Positioned underneath the 36-story Saturn rocket and its umbilical tower-which were supported on six steel columns-the 2,750-ton crawler then gently raised its platform until it had lifted the rocket and tower. Then it ponderously moved its 6,000-ton cargo through the door, over a concrete apron that had been slicked down with...
