Mechanix Illustrated

Magazine Overview

Title: Mechanix Illustrated
Issue Date: June 1951
Cover Headline: How Scientists Visualize The REAL Flying Saucer Men

This issue of Mechanix Illustrated delves into the speculative realm of extraterrestrial life, presenting how scientists and experts in 1951 envisioned alien beings based on the known or theorized conditions of various planets in our solar system. The magazine posits that these scientific visualizations are far more grounded and potentially more startling than the fanciful depictions often found in popular culture.

The Scientific Approach to Alien Life

The article begins by highlighting the growing scientific interest in detecting life beyond Earth. It notes that previously accepted theories are being discarded as new facts emerge, increasing the likelihood of life on other planets. The central question explored is: what kind of beings could inhabit these worlds, given their unique environmental parameters?

Expert Opinions on Extraterrestrial Forms

Several prominent scientists and experts are quoted, offering their insights:

• Dr. Henry Norris Russell (Princeton): Suggests that the number of inhabited worlds in the galaxy is considerable, with thousands being a more reasonable estimate than previously thought.
• H. Spencer Jones (Britain's Astronomer Royal): Believes that life on other worlds would likely develop in forms entirely unfamiliar and possibly beyond human conception.

Hypothetical Inhabitants of the Planets

The magazine then takes readers on a 'planet-hopping' tour, presenting imagined alien physiologies:

• Venus: Given its atmosphere of carbon dioxide and lack of oxygen and water, John W. Campbell, Jr. (editor of Astounding Science-Fiction) theorizes Venusians would have to breathe large amounts of air, leading to enormous lungs and barrel chests. Their diet of fats and hydrocarbons would necessitate large bellies and slow, lumbering movements, making a high culture unlikely.
• Mars: Major James R. Randolph (engineer, mathematician, and physicist) envisions Martians with slender limbs and large chests due to Mars's lower gravity. Their large mouths and nostrils would be adapted to a thin atmosphere, and their eyes would be dark-adapted. Their heads would appear disproportionately large compared to their bodies.
• Jupiter: Mr. Campbell suggests that Jupiter's gravity (two and a half to three times that of Earth) would necessitate massive muscular development. The perpetual darkness of its dense atmosphere would render eyes useless, leading to eyeless inhabitants who might perceive their surroundings through a 'built-in sonar system' similar to bats.
• Saturn, Uranus, and Neptune: Fletcher Pratt (military and naval analyst) posits that life on these cold, distant planets, with atmospheres rich in hydrogen, marsh gas, and ammonia but lacking oxygen, would require a nitrogen base. These creatures would need specialized organs to extract nitrogen and possess squat forms to cope with extreme gravity.
• Mercury: Kenneth Heuer (lecturer at the Hayden Planetarium) describes a Mercurian that would constantly follow the sun to stay in the habitable 'intermediate zone' between extreme heat and cold. Such a being would likely be four-footed, subsisting on lower vegetation like lichens, and possess a deep chest and large breathing orifices due to the tenuous atmosphere.
• Asteroids: Mr. Heuer also raises the possibility of 'mineral life' on the airless, waterless asteroids, suggesting that 'rock men' could exist, remaining stationary and communicating telepathically.

Recurring Themes and Editorial Stance

The recurring theme throughout the article is the power of scientific reasoning and imagination to construct plausible scenarios for extraterrestrial life. The editorial stance is one that encourages a rational, science-based approach to understanding the universe and its potential inhabitants, moving beyond mere fantasy. The magazine concludes by emphasizing that while direct contact with alien neighbors remains in the distant future, studying the heavens and using our imagination based on scientific observation is the current path to exploring these possibilities.
