Is the Martian Moon Phobos a Satellite Made by Martians?

Today I found the origin of the theory that the moons of Mars, Deimos and Phobos, or anyway, Phobos might be hollow and therefore artificially made satellites.

In the late 1950s and 1960s, the unusual orbital characteristics of Phobos led to speculations that it might be a hollow artificial object.

Around 1958, Russian astrophysicist Iosif Samuilovich Shklovsky, studying the secular acceleration of Phobos’ orbital motion, suggested a “thin sheet metal” structure for Phobos, a suggestion which led to speculations that Phobos was of artificial origin.^[

The article goes on to say that “S. Fred Singer, then science advisor to U.S. President Dwight D. Eisenhower, came out in support of Shklovsky’s theory, stating that ‘[Phobos’] purpose would probably be to sweep up radiation in Mars’ atmosphere, so that Martians could safely operate around their planet.'”

“Very interesting,” is all I can say.
