Mars was a energetic vacation spot in early science fiction due to its proximity. When H. G. Wells wanted a hazard from outer house, The Battle of the Worlds naturally seemed towards Mars, as a spot near Earth and one with the power to impress curiosity. Carefully studied at opposition in 1877, Mars provoked in Giovanni Schiaparelli the prospect of a community of canals, certainly feeding a civilization that may nonetheless be alive. No marvel new applied sciences turned towards the Crimson Planet as they grew to become accessible to maneuver past seen mild and even try and make contact with its inhabitants.
All this involves thoughts this morning due to an intriguing story despatched alongside by my good friend Al Jackson, whose work on interstellar propulsion is well-known in these pages, as is his deep involvement with the Apollo program. Al had by no means heard of the incident described within the story. It occurred in 1924, when at one other Martian opposition (an orbital alignment bringing Earth and Mars as shut as they’ll get throughout its 26-month orbit), the U. S. Navy imposed radio silence nationwide for 5 minutes as soon as an hour from August 21 to 24. The plan: Permit observatories worldwide to pay attention for Martians.
Picture: The duvet of the Edgar Rice Burroughs novel that may have been on Mars fans’ cabinets when the 1924 opposition occurred. Burroughs’ depiction of Mars was massively in style in its day.
This was critical SETI for its day. A dirigible was launched from the U. S. Naval Observatory carrying radio tools for these observations, with the potential of relaying its indicators again to a laboratory on the bottom. A navy cryptographer was introduced in to watch the scenario, as attested by a provocative New York Instances headline from August 23 of that yr: “Code Knowledgeable Prepared for Message.; RADIO HEARS THINGS AS MARS NEARS US.”
All this was information to me too, and thus I used to be entranced by the brand new article, a Instances essay from August 20 of this yr, written by Becky Ferreira. As a result of one thing certainly occurred and was reported in August 28 of 1924, once more within the Instances: “SEEKS SIGN FROM MARS IN 38-FOOT RADIO FILM; Dr. Todd Will Research {Photograph} of Mysterious Dots and Dashes Lately Recorded.”
As Ferreira explains::
A sequence of dots and dashes, captured by an airborne antenna, produced a photographic report of “a crudely drawn face,” based on information reviews. The tantalizing outcomes and subsequent media frenzy infected the general public’s creativeness. It appeared as if Mars was talking, however what was it making an attempt to say?
“The movie reveals a repetition, at intervals of a couple of half hour, of what seems to be a person’s face,” one of many experiment’s leaders mentioned days later.
You could recall that when Frank Drake started Undertaking Ozma at Inexperienced Financial institution in 1960, he homed in on close by stars Tau Ceti and Epsilon Eridani. And comparatively quickly he obtained a robust sign, inflicting him to ponder whether or not detecting different civilizations could be simple should you simply pointed your antenna and started to pay attention. However the sign turned out to be from an plane within the skies of West Virginia, an early SETI frustration, for radio frequency interference (RFI) is a supply of fixed concern, as witness the stir induced briefly in 2019 by what gave the impression to be a sign from Proxima Centauri, however was not.
I don’t assume the 1960 RFI expertise obtained a lot media play, if any, although Undertaking Ozma itself obtained a sure diploma of protection. However the ‘face’ discovered within the Mars radio reception of 1924 would have induced newspaper readers in that yr to recall Guglielmo Marconi’s 1920 declare that he had detected indicators “despatched by the inhabitants of different planets to the inhabitants of Earth.” This was an period bristling with the brand new exploration of radio wavelengths, which if they might provide communications throughout a continent or ocean, might certainly make doable a sign from one planet to a different.
The curiosity was worldwide, as one other Instances headline makes clear, this one from August 23, 1924: “RADIO HEARS THINGS AS MARS NEARS US; A 24-Tube Set in England Picks Up Sturdy Alerts Made in Harsh Dots. VANCOUVER ALSO FAVORED At Washington the Translator of McLean Telegrams Stands by to Decode Any Message.”
Again to the ‘face’ discovered within the analysis effort on the American aspect of the Atlantic, dug out of knowledge relayed from the dirigible. It was an astronomer named David Peck Todd who went to work with inventor Charles Francis Jenkins, utilizing a radio from the Nationwide Electrical Provide Firm designed to help troops in fight. Jenkins would use it to choose up any indicators from Mars as detected by the airship. He had for his half constructed a ‘radio digicam’ that may convert the radio information into optical flashes that may be imprinted on photographic paper, and it was inside the outcome that what gave the impression to be a face emerged. But it surely was one which not everybody noticed.
Jenkins himself was unimpressed, as I realized from a narrative titled “Freakish Radio writings on Mars Machine” that ran within the Each day Information on August 27. Let me quote the small piece in its entirety:
C. Francis Jenkins, Washington inventor, is investigating to establish reason for a sequence of freakish writings obtained on his particular machine designed to report any doable radio indicators from Mars.
The movie report reveals an association of dots and dashes and photos resembling a human face.
“I don’t assume the outcomes have something to do with Mars,” Jenkins mentioned.
Slightly extra digging within the newspaper archives revealed that Jenkins advised Related Press reporters, as recorded within the Buffalo Night Instances that very same day (“Radio Alerts Proven on Movies, Puzzle Savants at Capital”) that he thought the outcomes got here from radio frequency interference, saying what seems to be a face is “a freak which we are able to’t clarify.” The picture was certainly a part of a repeating sample recorded on Jenkins’ machine, however folks had been studying into it what they wished to see.

So the place is the 38-foot lengthy roll of photographic paper that induced the ‘detection’ of a face from Mars? The unique, based on Ferreira’s analysis, appears to have been misplaced, however Yale College Library lists three photographs from its assortment of supplies on David Peck Todd beneath the title “Martian indicators recorded by Jenkins.” So we now have not less than three pictures of Jenkins’ work, however to me not less than, no face appears obvious.
Additionally in Buffalo, the Buffalo American ran a for much longer piece titled “Astronomers Scan Mars To Uncover Human Life” for its August 28, 1924 challenge, which appears to be like on the complete challenge of learning Mars, although with out point out of Jenkins’ work. It contains this attention-grabbing paragraph:
…maybe Mars does see what is going on on the earth. In the event you had been on Mars and seemed on the earth you’ll see a star twice as giant as Mars seems to Buffalo, because the earth is double Mars’ measurement. Within the far distance on the identical aspect of the sky could be the solar however it might solely be two-thirds as giant because it seems right here. On the opposite smart could be discerned an enormous mass of vapor 1,300 occasions as giant because the earth. That will be Jupiter, which has not solidified but. You’ll additionally see a few moons. They mild Mars at evening and are liable for the tides on its oceans.
The Buffalo American article takes us proper into the Barsoom of Edgar Rice Burroughs’ creativeness, which at the moment had reached, in its 10-book sequence, The Chessmen of Mars (1922). In the event you’re a hard-core Burroughs fan, you might keep in mind the chess sport (recognized on Mars as Jetan) by which people play the function of the chess items and struggle to the demise (Burroughs cherished chess). Regardless of the Buffalo American’s point out of oceans, even in John Carter’s day Barsoom was depicted as a spot the place water sources had been uncommon and tightly managed.
And simply why research Mars within the first place? The newspaper article explains:
They wish to know if the earth is the one celestial globe on which the Creator put human beings and if the planets and stars past had been designed merely for the folks on Earth to admire.
The Mars of the day was a rare place. In researching this piece, I got here throughout this from an article on the 1924 opposition by Rowland Thomas that ran within the St. Louis Submit-Dispatch:
For a while astronomers everywhere in the world have been getting ready to get close-ups of Mars with their telescopes. The observers at Lowell Observatory, Flagstaff, Ariz., the place the late Percival Lowell carried on his lifelong research of the planet which confirmed his perception that clever life exists on it, reported that on the southern hemisphere of Mars, the place the polar ice cap is now melting beneath the rays of what’s there a spring-tide solar, huge areas of what could also be continents, marshland, prairies and the beds of dired-up oceans are continuously altering in look.

The canals are right here proven stuffed, with the vegetation in vigorous progress. Portray by H. Seppings Wright (1850-1937).
We’re nonetheless fourteen years from Orson Welles’ “Battle of the Worlds” broadcast in October of 1938, which gave loads of time for early SETI curiosity to develop together with journal science fiction, which within the US started within the pages of Hugo Gernsback’s radio magazines beginning with The Electrical Experimenter and shifting on to Science and Invention, however would quickly declare its personal devoted title in Superb Tales, whose first challenge appeared in April of 1926. A nod as properly to a sprinkling of earlier SF tales in Avenue & Smith’s pulp The Thrill E-book.
Ferreira’s article is terrific, and I’m glad to listen to that she is engaged on a guide on SETI. It took Mariner 4’s flyby in 1965 to lastly show what the floor of Mars was actually like, and by then the interstellar SETI effort was simply starting to get consideration. I’m wondering how the Mars fans of 1924 would have reacted to the information that regardless of the SETI efforts of the following 100 years, we nonetheless haven’t any proof of intelligence or certainly lifetime of any variety on one other world?
