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
