solid-state electronic detectors, which are sensitive to light. Like<br />

any other kind of computer hardware, these detectors are also very<br />

sensitive to radiation, <strong>and</strong> would have been next to useless on the<br />

Moon, even if they had been encased in metal. In that case, the<br />

older technology actually did a better job than would modern<br />

technology.<br />

3. Dust on the Moon’s Surface<br />

The surface of the Moon is dusty. Before any machines l<strong>and</strong>ed<br />

on the Moon, no one really knew what the actual surface was like.<br />

Scientific analysis showed that the Moon’s surface was rocky, <strong>and</strong><br />

we could even determine the composition of some of the rocks.<br />

However, the actual texture of the surface was unknown. It was<br />

conjectured by some that the intense sunlight, consisting of ultraviolet<br />

light unfiltered by an atmosphere, might break down the<br />

rocks into a dust. Micrometeorite hits might do the same. But no<br />

one knew for sure if the dust even existed, or how deep it might be.<br />

When the first soft l<strong>and</strong>ings were made by Soviet <strong>and</strong> American<br />

probes, it was found that the dust was only a few millimeters<br />

to centimeters thick. That was a great relief. No one wanted the<br />

Apollo astronauts to sink into a s<strong>and</strong> trap.<br />

The dust on the Moon is peculiar. It is extraordinarily fine, like<br />

well-ground flour. It is also extremely dry, like everything else on<br />

the Moon. Unlike the Earth, the Moon has virtually no water at<br />

all anywhere on the surface.<br />

Misunderst<strong>and</strong>ing the properties of this dust in an airless environment<br />

leads to the breakdown of the next hoax-believer claim,<br />

dealing with the l<strong>and</strong>ing of the lunar module (or LM), the oddlooking<br />

contraption used by the Apollo astronauts to l<strong>and</strong> on the<br />

Moon. The LM had four l<strong>and</strong>ing legs with disk-shaped feet at<br />

the ends, <strong>and</strong> between them was a powerful rocket used to slow the<br />

descent speed as the LM approached the surface.<br />

The conspiracy-theorists claim that the rocket had a thrust of<br />

10,000 pounds, <strong>and</strong> therefore should have left a substantial crater<br />

on the Moon’s surface. Also, that much thrust would blow away<br />

all the dust underneath it. How could the l<strong>and</strong>er’s legs <strong>and</strong> the
