Every Shot — A Hole In One / Chap. 8 p. 70<br />
239,000-mile trip at 16,692 miles in diameter. 13<br />
At the halfway mark the circle of uncertainty around the Moon would be 8346 miles in<br />
diameter. One could be over 4,100 miles off course and possibly only detect half of it. A<br />
burn to change inertial vector of 50 tons of a space ship by a few degrees, would certainly<br />
not be a small affair, because the center of mass would want to stay on that old course.<br />
Here on Earth our vehicles rub away inertial vectors by friction. A car does it with tires<br />
that scrub by friction on the roadway as it changes direction; an airplane by the resistance or<br />
friction of the air developed in banking; and a boat by the high friction of the water.<br />
However, in space there is no friction! Cancellation of the inertial vector requires a burn at<br />
right angles to the course powerful enough to accelerate the ship so that the center of mass is<br />
on a new vector heading for the lunar ring of entry. More importantly, an error of this<br />
magnitude would cause many more frequent adjustments in course.<br />
From the Earth, the Moon's area of this circle of uncertainty is 218,829,885 square<br />
miles. 14 To find the odds of hitting the entry target ring around the Moon we must first find<br />
the area of the plane surface of the Moon. It is 3,664,353 square miles. 15 Collins claims the<br />
ring of return to Earth is only 40 miles thick, and if I generously allow the ring of entry to the<br />
Moon to be 5 times that size (200 miles), the total area encompassed would be 5,147,185<br />
square miles. 16 Subtracting the Moon's area from this leaves us with a target area of<br />
1,482,832 square miles. 17 This seems rather large. However, in comparison with the<br />
218,829,885 square miles of uncertainty we find the probability for hitting that ring with<br />
only one burn to be — .67 percent. 18<br />
If <strong>NASA</strong> made no other corrections, as they claim, they would have only one chance in<br />
147 of sliding into the lunar ring of entry. This figure is derived by comparing the area of<br />
the lunar entry zone and the area of uncertainty. 19 To claim to have done exactly this, eight<br />
times in a row, against odds such as these, boggles the mind — not to mention Murphy's<br />
Law!<br />
It is even more unbelievable that Houston, at the long end of a 1.3-second transmission<br />
time lag, was supposed to make Go-No-Go lunar landing decision for each of the LEMs.<br />
This means that anything transmitted took 1.3 seconds to get to Houston, then after a decision<br />
was made, it took another 1.3 seconds to get the information back. Would you like to<br />
drive in traffic like that<br />
Harry Hurt writes how the LEM was roughly 7,000 feet above the Moon's surface<br />
waiting for the Go-No go decision from Houston. "According to ground based radar, the<br />
spacecraft was diving toward the lunar surface a good fifteen mph (twenty-three feet per<br />
second) faster than called for in the flight plan." 20 Wow! Their resolution in range was better<br />
than anything ever done before. Or since! Not only could that radar tell its exact altitude, it<br />
could also divine its velocity down to one foot per second. Wow!<br />
Despite all this exactness, the Eagle Lander of Apollo 11 fame missed the chosen landing<br />
spot. Michael Collins writes, "Of course, the ground can take its own measurements as<br />
well, but it has no way of really judging where the LM came down, except by comparing<br />
Neil and Buzz's description of their surrounding terrain (lurain) with the rather crude maps<br />
Houston has." 21 (By "ground" Collins means "mission control").<br />
