...both together to symbolize the mixing of blood. After swearing to hold the family above his religion, his country, and his wife and children, the inductee finishes the ritual. A picture of a saint or a religious card is placed in his cupped hands and ignited. As the paper burns, the inductee, together with his sponsor, proclaims: "If I ever violate this oath, may I burn as this paper...
...lunar surface. The crucial word from Houston was relayed by Michael Collins, Columbia pilot, when a burst of static momentarily cut Eagle off from the ground: "You are go for PDI [powered descent insertion]." Again Eagle's descent engine fired, beginning a twelve-minute burn that was scheduled to end only when the craft was within two yards of the lunar surface. One of the most dangerous parts of Apollo 11 's long journey had begun...
...electrical or oxygen systems, or a collision with a large meteor would almost surely result in tragedy. But lift-off was the most nerve-racking part of the mission. If the ascent engine had failed to start, Eagle would have been stranded on the lunar surface. Too short a burn would have tossed the module into a trajectory that would send it smashing back onto the lunar surface. Had the LM achieved an orbit with an apocynthion (high point) much less than 50,000 ft., Columbia would have been unable to reach it. As it turned out, departure from...
Continuing their flawless flight, the astronauts zoomed past the western rim of the moon at 5,645 m.p.h. They were whipped behind the far side and into lunar orbit by the moon's gravity and a 5-min. 57-sec. burn of the reliable SPS engine that reduced their speed to 3,736 m.p.h. When they emerged from behind the eastern edge, after 34 minutes during which radio communication was blocked, they had dropped into a 70-by 196-mile-high orbit...
...lunar module before its long separation from the command module. They paid particular attention to Eagle's propulsion systems?the tanks containing the hypergolic fuels that fire the descent and ascent engines, and the pressure gauges on the helium that forces the fuels into the combustion chambers, where they burn upon contact with one another. Efficient and businesslike, they completed the check 30 minutes ahead of schedule. Two minutes before the spacecraft disappeared behind the moon on its 13th revolution, Houston advised: "We're go for undocking." Tense minutes followed until the spacecraft emerged from the far side and Armstrong...
