Mars The Red Planet

Earthlings have always been fascinated by the planet, Mars. The "little green men from Mars" invading Earth has been the stuff of science fiction for decades. On October 30, 1938, Orson Welles did a dramatization of H. G. Wells's "War of the Worlds" on the Mercury Theatre on the Air radio show. During the four commercial breaks of the program, there were disclaimers aired telling the audience that the content was fictional. Still, panic erupted in towns across America.

There was a new 40-inch telescope being built by the University of Chicago in 1895. An astronomy professor, Samual Leland Phelps, wrote a book about the project called "World Making." In the book, the professor wrote, "It will be possible to see cities on Mars, to detect navies in [its] harbors, and the smoke of great manufacturing cities and towns...Is Mars inhabited? There can be little doubt of it...conditions are all favorable for life, and life, too, of a high order. Is it possible to know this of a certainty? Certainly." WellÖnot exactly, professor!

From observations of Mars from stationary observatories on earth, astronomers concluded that:

1. The reddish color of Mars is caused by red rocks and dust.

2. The polar ice caps increase and decrease according to seasons.

3. There are what were thought to be canals on the surface. (That has since been disproved)

4. There are areas of Mars that change color. (It was believed that this was vegetation, but that has been disproved, as well.)

5. Mars has an atmosphere.

Space probes, beginning with Mariner 4, 6, 7, and 9 from 1965 through 1971, and the Viking 1 and 2 probes in 1976, disproved many of the previously held beliefs about Mars. We are learning more about Mars all the time, and one important fact is that there aren't any little green (or any other color) men living on Mars.
