(9) By space navigation standards, quartz crystal clocks aren't very stable. After only an hour, even the best-performing quartz oscillators can be off by a nanosecond (one billionth of a second). After six weeks, they may be off by a full millisecond (one thousandth of a second), or a distance error of 185 miles (300 kilometers). That would have a huge impact on measuring the position of a fast-moving spacecraft.

(10) Atomic clocks combine a quartz crystal oscillator with an ensemble of atoms to achieve greater stability. NASA's Deep Space Atomic Clock will be off by less than a nanosecond after four days and less than a microsecond (one millionth of a second) after 10 years. This is equivalent to being off by only one second every 10 million years.

How does the author develop her point that atomic clocks are better than quartz crystal clocks for space navigation?

Final answer:

The author develops the point that atomic clocks are better than quartz crystal clocks for space navigation by comparing and contrasting their stability and accuracy.

Step-by-step explanation:

The author develops the point that atomic clocks are better than quartz crystal clocks for space navigation by comparing and contrasting the stability and accuracy of both types of clocks.

Quartz crystal clocks, while commonly used in everyday applications, are not very stable by space navigation standards. They can be off by a nanosecond after just an hour and can be off by a millisecond after six weeks, resulting in significant distance errors.

On the other hand, atomic clocks combine a quartz crystal oscillator with an ensemble of atoms to achieve much greater stability. NASA's Deep Space Atomic Clock, for example, is off by less than a nanosecond after four days and less than a microsecond after 10 years. This level of precision and stability is crucial for measuring the position of fast-moving spacecraft accurately.
