Then, after 1½ revolutions of the earth, a five-minute blast from the S-4B sent the fifth U.S. manned lunar mission on a long glide toward the moon...
...conserving stratagem that should reduce some of the danger. On previous missions, the lunar lander separated from the mother ship while the two were circling the moon at an altitude of 69 miles. But Apollo 13's command vehicle, Odyssey, will be sent into a more elliptical lunar orbit that will drop it to a height of only nine miles before Aquarius is released. As a result, the lunar lander will use less fuel in its final descent and have enough left to hover a crucial 15 seconds longer before touching down. That extra time may well be necessary...
...years since that limerick was written by one of the Caltech scientists who built Explorer I, the men involved in the project matured and moved on to more ambitious space programs. But Explorer I, the first U.S. satellite, remained steadfastly in orbit, a seemingly immortal reminder of one of the most important discoveries of the Space...
