...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...
...moon arrived at the closest point in its orbit at 5 a. m. this morning (223,600 miles from earth), and it will only be a few hundred miles farther away tomorrow. Thus? Saturday's eclipse will be total, not acicular...
...coincidence, the moon's diameter will appear to be the same as the sun's tomorrow, but this is not always the case. Since the moon's orbit is not circular, there are times when the satellite passes in front of the sun but is so far from the earth that the cone of the umbra falls short of the earth's surface. When this happens, the moon will appear smaller than the sun, and at mid-eclipse, the sun will form a ring around the smaller moon-an annular eclipse...

Unlike Peking, Tokyo has a head start toward a delivery system; two weeks ago, the Japanese became the fourth member of the exclusive space club (others: the U.S., the Soviet Union and France) by putting a 20-lb satellite into orbit from a launch pad on Kyushu Island...
