The earth's rotation upon its axis appears to be slowing slightly. However, this decrease is so minute that the length of a day will not be altered more than a fraction of a second in centuries. Our planet digresses from a straight line one-ninth of an inch every eighteen miles. If the turn was only a tenth of an inch, our globe would be too cold for life. Consider the complexities of space travel.
Success depends upon the precise movements of the heavenly bodies.
When America's astronauts traveled to the moon in July of 1969, intricate mathematical calculations had to be made in order to insure that they would arrive safely at their lunar destination. The moon is a moving target. It circles the earth at a speed of more than 2,000 miles per hour. Space officials had to know exactly where the moon would be at a given hour. Only the amazing mechanics of the solar system could have facilitated this achievement.
