Mars was a lively destination in early science fiction because of its proximity. When H. G. Wells needed a danger from outer space, The War of the Worlds naturally looked toward Mars, as a place close to Earth and one with the ability to provoke curiosity. Closely studied at opposition in 1877, Mars provoked in Giovanni Schiaparelli the prospect of a network of canals, surely feeding a civilization that might still be alive. No wonder new technologies turned toward the Red Planet as they became available to move beyond visible light and even attempt to make contact with its inhabitants.
All this comes to mind this morning because of an intriguing story sent along by my 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 never heard of the incident described in the story. It occurred in 1924, when at another Martian opposition (an orbital alignment bringing Earth and Mars as close as they’ll get during its 26-month orbit), the U. S. Navy imposed radio silence nationwide for five minutes once an hour from August 21 to 24. The plan: Allow observatories worldwide to listen for Martians.
Image: The cover of the Edgar Rice Burroughs novel that would have been on Mars enthusiasts’ shelves when the 1924 opposition occurred. Burroughs’ depiction of Mars was hugely popular in its day.
This was serious SETI for its day. A dirigible was launched from the U. S. Naval Observatory carrying radio equipment for these observations, with the capability of relaying its signals back to a laboratory on the ground. A military cryptographer was brought in to monitor the situation, as attested by a provocative New York Times headline from August 23 of that year: “Code Expert Ready for Message.; RADIO HEARS THINGS AS MARS NEARS US.”
All this was news to me too, and thus I was entranced by the new article, a Times essay from August 20 of this year, written by Becky Ferreira. Because something indeed happened and was reported in August 28 of 1924, again in the Times: “SEEKS SIGN FROM MARS IN 38-FOOT RADIO FILM; Dr. Todd Will Study Photograph of Mysterious Dots and Dashes Recently Recorded.”
As Ferreira explains::
A series of dots and dashes, captured by an airborne antenna, produced a photographic record of “a crudely drawn face,” according to news reports. The tantalizing results and subsequent media frenzy inflamed the public’s imagination. It seemed as if Mars was speaking, but what was it trying to say?
“The film shows a repetition, at intervals of about a half hour, of what appears to be a man’s face,” one of the experiment’s leaders said days later.
You may recall that when Frank Drake began Project Ozma at Green Bank in 1960, he homed in on nearby stars Tau Ceti and Epsilon Eridani. And relatively soon he got a strong signal, causing him to ponder whether detecting other civilizations might be easy if you just pointed your antenna and began to listen. But the signal turned out to be from an aircraft in the skies of West Virginia, an early SETI frustration, for radio frequency interference (RFI) is a source of constant concern, as witness the stir caused briefly in 2019 by what appeared to be a signal from Proxima Centauri, but was not.
I don’t think the 1960 RFI experience got much media play, if any, though Project Ozma itself received a certain degree of coverage. But the ‘face’ found in the Mars radio reception of 1924 would have caused newspaper readers in that year to recall Guglielmo Marconi’s 1920 claim that he had detected signals “sent by the inhabitants of other planets to the inhabitants of Earth.” This was an era bristling with the new exploration of radio wavelengths, which if they could offer communications across a continent or ocean, could surely make possible a signal from one planet to another.
The interest was international, as another Times headline makes clear, this one from August 23, 1924: “RADIO HEARS THINGS AS MARS NEARS US; A 24-Tube Set in England Picks Up Strong Signals Made in Harsh Dots. VANCOUVER ALSO FAVORED At Washington the Translator of McLean Telegrams Stands by to Decode Any Message.”
Back to the ‘face’ found in the research effort on the American side of the Atlantic, dug out of data relayed from the dirigible. It was an astronomer named David Peck Todd who went to work with inventor Charles Francis Jenkins, using a radio from the National Electrical Supply Company designed to support troops in combat. Jenkins would use it to pick up any signals from Mars as detected by the airship. He had for his part built a ‘radio camera’ that would convert the radio data into optical flashes that would be imprinted on photographic paper, and it was within the result that what seemed to be a face emerged. But it was one that not everyone saw.
Jenkins himself was unimpressed, as I learned from a story titled “Freakish Radio writings on Mars Machine” that ran in the Daily News on August 27. Let me quote the small piece in its entirety:
C. Francis Jenkins, Washington inventor, is investigating to ascertain cause of a series of freakish writings received on his special machine designed to record any possible radio signals from Mars.
The film record shows an arrangement of dots and dashes and pictures resembling a human face.
“I do not think the results have anything to do with Mars,” Jenkins said.
A little more digging in the newspaper archives revealed that Jenkins told Associated Press reporters, as recorded in the Buffalo Evening Times that same day (“Radio Signals Shown on Films, Puzzle Savants at Capital”) that he thought the results came from radio frequency interference, saying what appears to be a face is “a freak which we can’t explain.” The image was indeed part of a repeating pattern recorded on Jenkins’ machine, but people were reading into it what they wanted to see.
Image: What remains of the 1924 ‘face on Mars’ detection, as captured through photography of the original paper roll produced by Jenkins in his lab. Credit: Yale University Library.
So where is the 38-foot long roll of photographic paper that caused the ‘detection’ of a face from Mars? The original, according to Ferreira’s research, seems to have been lost, but Yale University Library lists three images from its collection of materials on David Peck Todd under the title “Martian signals recorded by Jenkins.” So we have at least three photographs of Jenkins’ work, but to me at least, no face seems apparent.
Also in Buffalo, the Buffalo American ran a much longer piece titled “Astronomers Scan Mars To Discover Human Life” for its August 28, 1924 issue, which looks at the whole issue of studying Mars, though without mention of Jenkins’ work. It includes this interesting paragraph:
…perhaps Mars does see what is happening on the earth. If you were on Mars and looked at the earth you would see a star twice as large as Mars appears to Buffalo, as the earth is double Mars’ size. In the far distance on the same side of the sky would be the sun but it would only be two-thirds as large as it appears here. On the other wise would be discerned a huge mass of vapor 1,300 times as large as the earth. That would be Jupiter, which has not solidified yet. You would also see a couple of moons. They light Mars at night and are responsible for the tides on its oceans.
The Buffalo American article takes us right into the Barsoom of Edgar Rice Burroughs’ imagination, which at that time had reached, in its 10-book series, The Chessmen of Mars (1922). If you’re a hard-core Burroughs fan, you may remember the chess game (known on Mars as Jetan) in which humans play the role of the chess pieces and fight to the death (Burroughs loved chess). Despite the Buffalo American’s mention of oceans, even in John Carter’s day Barsoom was depicted as a place where water resources were rare and tightly controlled.
And just why study Mars in the first place? The newspaper article explains:
They want to know if the earth is the only celestial globe on which the Creator put human beings and if the planets and stars beyond were designed merely for the people on Earth to admire.
The Mars of the day was an extraordinary place. In researching this piece, I came across this from an article on the 1924 opposition by Rowland Thomas that ran in the St. Louis Post-Dispatch:
For some time astronomers all over the world have been preparing to get close-ups of Mars with their telescopes. The observers at Lowell Observatory, Flagstaff, Ariz., where the late Percival Lowell carried on his lifelong study of the planet which confirmed his belief that intelligent life exists on it, reported that on the southern hemisphere of Mars, where the polar ice cap is now melting under the rays of what is there a spring-tide sun, vast areas of what may be continents, marshland, prairies and the beds of dired-up oceans are constantly changing in appearance.
Image: Mars as conceived by astronomer Percival Lowell (1855-1916) and discussed by him in three books: Mars (1895), Mars and Its Canals (1906), and Mars As the Abode of Life (1908). The canals are here shown filled, with the vegetation in vigorous growth. Painting by H. Seppings Wright (1850-1937).
We’re still fourteen years from Orson Welles’ “War of the Worlds” broadcast in October of 1938, which gave plenty of time for early SETI interest to grow along with magazine science fiction, which in the US began in the pages of Hugo Gernsback’s radio magazines starting with The Electrical Experimenter and moving on to Science and Invention, but would soon claim its own dedicated title in Amazing Stories, whose first issue appeared in April of 1926. A nod as well to a sprinkling of earlier SF stories in Street & Smith’s pulp The Thrill Book.
Ferreira’s article is terrific, and I’m glad to hear that she is working on a book on SETI. It took Mariner 4’s flyby in 1965 to finally demonstrate what the surface of Mars was really like, and by then the interstellar SETI effort was just beginning to get attention. I wonder how the Mars enthusiasts of 1924 would have reacted to the news that despite the SETI efforts of the ensuing 100 years, we still have no proof of intelligence or indeed life of any kind on another world?
Only a hundred years ago…these reports and speculations must have sounded very convincing to our parents. And a century is trivial in the great scheme of things, both of my parents were born over a hundred years ago.
I recall reading reports of visual astronomers documenting green vegetation spreading from the Martian poles as the icecaps melted in spring–and of spectroscopy hinting at the presence of chlorophyll!. These observations were from way before my time, but were still being cited and debated as evidence of the canals when I was a student. I also recall reading about one astronomer glimpsing a huge white “W” shaped feature on the Martian surface during a moment of exceptionally clear seeing during a particularly close opposition. Was this the Martians trying to signal us by lighting fires, or using smoke? Serious proposals were made to light forest fires in the Siberian taiga to answer this signal
We must remember, that Mars is faint through the telescope, and only a time exposure could reveal detail on the slow photographic emulsions of that time. But the planet rotates, and long exposures were blurred! The planet is close enough for visual examination only at opposition, for a few weeks every few years, and our own atmosphere is turbulent and cloudy. Even back then, we knew dust storms frequently obscured the Martian surface, and these often seemed to coincide with the times the planets were in best alignment for telescopic inspection. Mars was always at the extreme limit of possible observation, always at the very edge of wonder.
None of us is immune to this sort of self-deception. I once recall seeing (through a telescope) a huge rectangular structure on the surface of the moon, like an immense bridge spanning a miles- wide crater! Of course, the next night it wasn’t there, just a trick of light and shadow and perspective.
But these reports can tell us more about ourselves than they do about the Martians. Someone could see a “face” in those Martian scans in 1924, but what makes us think Martians would even have faces? And we are still seeing humanoid faces on Mars today.
Victorian UFOs looked like balloons and gliders…we tend to see what we expect to see.
As witness the ‘phantom airship’ of 1897.
The stories about the phantom airships of 1897 are just as wild as the modern era UFO reports. They even include a dead alien supposedly buried in a small town after its airship crashed…

I recall reading in the wonderful popular book Astronomy with an Opera Glass, originally published in 1888, that people who saw Venus at the time did not mistake it for a device of some advanced ETI as later folks would, but rather a hot-air balloon strung up with electric lights by that Edison inventor fellow.

Great catch, Larry. Thanks for the link!
Here is the full quote from my description above, on page 2. Amazing how you only have to change a few items, and this could still be the case today…
A singular proof of popular ignorance of the starry heavens, as well as of popular curiosity concerning any uncommon celestial phenomenon, is furnished by the curious notions prevailing about the planet Venus.
When Venus began to attract general attention in the western sky in the early evenings of the spring of 1887, speculation quickly became rife about it, particularly on the great Brooklyn Bridge.
As the planet hung dazzlingly bright over the New Jersey horizon, some people appeared to think it was the light of Liberty’s torch, mistaking the bronze goddess’s real flambeau for a part of the electric-light system of the metropolis.
Finally (to judge from the letters written to the newspapers, and the questions asked of individuals supposed to know something about the secrets of the sky), the conviction seems to have become pretty widely distributed that the strange light in the west was no less than an electrically illuminated balloon, nightly sent skyward by Mr. Edison, for no other conceivable reason than a wizardly desire to mystify his fellow-men.
I have positive information that this ridiculous notion has been actually entertained by more than one person of intelligence. And as Venus glowed with increasing splendor in- the serene evenings of June, she continued to be mistaken for some petty artificial light instead of the magnificent world that she was, sparkling out there in the sunshine like a globe of burnished silver.
Yet Venus as an evening star is not so rare a phenomenon that people of intelligence should be surprised at it.
Here is a video on the phantom airships of 1897:
https://youtu.be/hmNWl96jjCI?si=Wy8XpgD8wPjghPe_
In the last years of the 19th Century, the public looked to the skies in excited anticipation of powered flight. The dream of manned flight had teased humanity for centuries, and now it seemed the dream was on the cusp of becoming a reality. And so when the good people of California, of Nebraska, of Wisconsin and Kansas, Iowa and Illinois, gazed up into the night’s sky and saw a mysterious airship, there was amazement. Yet, this phantom airship vanished into history, and we still don’t know who was behind it. What happened in the skies over the United States in 1896 and 1897? What is the truth behind the phantom airship seen by 100,000 people?
In this video, we will trace the phantom airship’s course across America, and ponder over three theories that might, or might not, explain this mystery.
For those who like to know these things:
Robert E. Bartholomew, ‘The Airship Hysteria of 1896-97’, Skeptical Inquirer, Vol. 14, (Winter 1990), pp. 171-181, and Robert E. Bartholomew, ‘Michigan and the Great Mass Hysteria Episode of 1897’, Michigan Historical Review, Vol. 24, No. 1, (Spring, 1998), pp. 133-141.
Initially, I was wondering how the 1924 signal was converted from a 1D stream to a 2D face. How would they know to think of breaking it up into lines like a tv signal that had not been invented yet?
But with the image of the signal, I do see what was meant by faces. The top stream can be seen as “hair”, with 2 “eyes” (and sometimes “eyebrows” below it). then a smudge that could be a “nose”, and a smudge below that is a “mouth”. In at least one case that smudge mouth looks like it is smiling.
So lots of repeating “faces” in the signal.
An appropriate example of humans seeing things that are not there, just as Lowell saw canals and vegetation, and with them he “logically” built a dying civilization, not unlike the scenario Wells had used for his “War of the Worlds”.
It is a lot easier to see the faces in that signal, than the compounds encoded in the “A Sign from Space” signal that took a long time to interpret successfully.
In 1924 there was enough radio equipment and probably unscreened electrical motors, that the US Navy could not enforce true radio silence even in the USA, let alone any signals from a distance bouncing off the ionosphere. A repeating signal like that received was mostly likely RFI from a machine. It would be ironic if the signal emanated from something on board the dirigible itself, such as a generator on the engines to power the radio equipment.
I remember reading somewhere that by the turn of twentieth century raster images were being transmitted through the Transatlantic undersea cable. European and American newspaper readers could see recognizable portraits of individuals across an ocean just hours after their assumption of notoriety.
@Hewnry,
Thanks for the correction. I had thought that such raster approach was later, Wikipedia confirms your memory. https://en.wikipedia.org/wiki/Wirephoto
If you have ever watched the charming TV series “Murdoch Mysteries” (AKA “The Artful Detective”) set at the turn of the 20th century, in Toronto, Det. William Murdoch is always inventing technologies ahead of its time that help solve a case, and this was one of those inventions. The series always named them in reference to later technologies, e.g. “Finger Marks” for fingerprinting.
Here is a collection of good articles on the Mars broadcasts of 1924, with the first ones having many relevant links on the subject. None of these are simple rehashes on the topic and all contain something of unique value to this fascinating essay:

Percival Lowell may have been off about the Canals of Mars. He may even have not been the best draftsman when attempting to reproduce what he saw through the telescope, but he was a very good writer. Check out this sample from his 1895 book Mars as the Abode of Life here:
https://avalonlibrary.net/ebooks/Percival%20Lowell%20-%20Mars%20As%20The%20Abode%20of%20Life.pdf
As for mind beyond the confines of our tiny globe, modesty, backed by a probability little short of demonstration, forbids the thought that we are the sole thinkers in this great universe.
That we are the only minds in space it takes indeed a very small mind to fancy. Our
relative insignificance commonly escapes us. If we reduce the universe to a scale on which we can conceive it, that on which the earth shall be represented by a good-sized pea, with a grain of mustard seed, the moon, circling about it at a distance of seven inches, the sun would be a globe two feet in diameter, two hundred and twenty feet away.
Mars, a much smaller pea, would circle round the two-foot globe, three hundred and fifty feet from its surface; Jupiter, an orange, at a distance of a quarter of a mile; Saturn, a small orange, at two fifths of a mile; and Uranus and Neptune, good-sized plums, three quarters of a mile and a mile and a quarter away, respectively.
The nearest star would lie two hundred and thirty thousand miles off, or at about the actual distance of our own moon, and the other stars at corresponding distances beyond that; that is, on a scale upon which the moon should be but seven inches off, the nearest star would still be as far from us as the moon is now.
When we think that each of these stars is probably the centre of a solar system on a grander scale than our own, we cannot seriously take ourselves to be the only minds in the universe.
But improbable as the absence of ultra-terrestrial life in a general way is, up to the
present time we have had no proof of its particular existence in worlds beyond our own.
Whether the observations I am now to describe have revealed something on the point I shall leave the reader himself to judge, after laying the facts before him; for it is with this in view that the present papers will deal with Mars, since any answer on this point is the most generally interesting outcome of a study of the planet.
That the observations also disclose the fact that the hitherto accepted period of its rotation proves to be too small by the hundredth of a second is a matter of far greater moment, of course, but one which leaves the average man comparatively cool.
That Mars, however, should be peopled by intelligent beings, although physically they be utterly unlike us, more goblins than men or animals, is a suggestion which appeals romantically, at least, to everybody.
To determine whether a planet be the abode of life, two questions about it must be answered in turn: first, are its physical conditions such as to render it habitable? and secondly, are there any signs of its actual habitation? Unless we can answer the first point satisfactorily, it were futile to seek for evidence of the second.
And here is the online version of Lowell’s work from 1906 titled Mars and Its Canals, complete with illustrations:

So glad to see your references here to Edgar Rice Burroughs’ Mars series, Paul.
So, yes, I guess include me as a “hard-core Burroughs fan,” lol.
I know that – this quite early – work sometimes is dismissed as pulp fiction; but, even if perhaps so, I don’t readily dismiss work that inspires and stirs the imagination.
Who knows how much Burroughs’ early work in the overall genre inspired and stirred the imaginations of later sci fi writers in their youth.
First we dream, and then we reach further.
In my family, A Princess of Mars – per his 1922 handwritten inscription on the flyleaf – was “Book 3″ in the budding library of my then maybe 12-year-old maternal grandfather (to be, of course), with whom I share two-thirds of my name.
His hard cover editions from the series – starting in 1917 by that particular publisher – were passed down to my generation and similarly inspired and stirred our imaginations.
Those books in part are why I ultimately began working during personal time, later as a lawyer, on a draft constitution for an eventual settlement of Mars – as a purportedly grown up version of the young boy who had been inspired by Burroughs’ Mars series.
And those books definitely are why I refer to that draft document as “A Constitution of Mars,” as an homage.
(Looking to try to get an initial installment – within, yes, a series – to you for possible editorial review for hopefully early 2025.)
It would be interesting to see the contemporaneous edition with the color cover art work from The Chessmen of Mars that you have in your first image.
The hard cover editions from my family’s library instead have more traditional book covers, i.e., book title and author with no cover art. But they include J. Allen St. John’s illustrations interspersed in the volumes in moderately glossy prints in black and white tones – with that particular cover art being found thus instead in black and white toward the end of my family’s 1922 Grossett & Dunlap edition of that volume.
Those illustrations were very much an integral part of the allure of the Mars series.
And they inspired as well a next generation of also graphic artists, including Frank Frazetta. I had been thinking that they were “Frazetta-like before Frazetta” – until I saw in doing background research for this note that Frazetta indeed was a disciple of St. John, as per Wikipedia. And Frazetta himself later did do a number of illustrations based upon the Mars series in the 1960’s and ‘70’s.
Burroughs’ – and St. John’s – work most definitely will remain part of the fabric of imagination that we have woven about one of our nearest planetary neighbors. And will remain so regardless of what science since has taught regarding the planet – ultimately to provide even more fuel for the imaginations of those who see its orangish red light seemingly so close in our night sky, particularly while in opposition.
I’m sure those Mars enthusiasts of 1924, including perhaps my then teenage grandfather (to be), would still – if they knew what we know now – be looking out to the heavens with enthusiasm.
Especially now that we know how many other worlds are out there – and no doubt are yet to be discovered out there – over and above Mars and our own solar system.
Doubting all the while that those worlds were hung there in the firmament “merely for the people on Earth to admire.”
Thanks so much, George. What a wonderful reminiscence. I have many fine memories of reading Burroughs when the paperback editions started flooding the newsstands back in the 1960s, and discovering Barsoom and the other science fictional venues, not to mention Tarzan. I remember how wonderful it felt knowing there were so many of these books out there, though I never did read the complete Burroughs corpus.
It is interesting that the cover by J. Allen St. John has been reused on the cover of different printings for nearly a century!
Chessmen of Mars covers.
Some staying power.
The bizarre Russian silent film _Aelita, Queen of Mars_ used the mystery radio signals as a topical way to drive the plot. A radio engineer at the Moscow radio station (who is, for reasons I won’t go into, disguising himself as a _different_ engineer at the Moscow radio station) detects the signals and in what looks like a long-weekend craft project, builds a rocket to go to Mars. He’s accompanied by a heroic Red Army veteran and a comic-relief secret police spy, because this is Bolshevik Russia after all. Various hijinks ensue, including a revolution and some of the most astonishing costume designs you’ve ever seen.
You cannot mention this film Aelita and tease readers about it then not show them where they can find and watch it…

A fascinating look at Mars via Disney from 1957. Even some professional astronomers were still wondering if Sol 4 has or had intelligent life…
https://youtu.be/lHVrY4B7uzY?si=4LHvCVGutY3vu0fV
The idea of “Martians” was discredited starting around this time. But what I call the “Lowellian” environmental Mars, defined as a Mars where you could walk around wearing only breathing gear and where there was plant life, persisted right up until the Mariner 4 flyby in July of 1965.
The Arthur Clarke novel “Sands of Mars” depicted such a Lowellian Mars. He wrote it around 1949.
The first SF novel I ever read, in 1953, was Red Planet , Robert Heinlein, 1949. It had ‘Lowell’s’ Old Mars as a setting. So did Bradbury’s Martian Chronicles , tho that was kind of Alternate Universe Old Mars. I can’t remember but seems Clarke did not have ‘Lowell’s’ Mars in Sands of Mars.
I am sure ‘Lowell’s’ Mars shows up in other SF stories 30s , 40’s and 50’s. By 1950, actually starting in the 1940’s SF authors were getting tired of the solar system, and most space travel stories went Interstellar.
I know that there was more Mars stories and Novels after Mariner 4 in SF , those had the New Mars.
It is interesting that by the early 1920s astronomers had cast doubt on the Canals. By 1950 in the professional astronomy community Old Mars was not the accepted model, but I guess, this was not the general knowledge to SF writers , I guess?
(One notes there an Old Mars anthology of SF short Stories using Old Mars , 2013 Old Mars. )
Hello
The brain’s ability to create images is known: it is the pareidolia…the imagination & enthusiam for new technologies during the 20’s does the rest.
Technically speaking, at the time when radio was still on simple analogue low frequencies, the signal seen on the Jenkins roll reminds me of the RFI generated by the huge electric turbines of unshielded or poorly shielded industrial machines. The H Ford page below also offers electric streetcar ; we were still in the electrical-industrial age…
On this link, you can see the receiver of Jenkins (a real radio strainer in wood ! :) and the message sent by the Navy : Henry will tell us what he thinks ;)
All this makes us smile today but what is interesting is precisely that the authorities have become involved in the game. Imagine today that governments decide to block for example all satellite communications for 1 hour on a simple assumption !
https://en.wikipedia.org/wiki/Pareidolia
https://www.thehenryford.org/explore/blog/reaching-for-mars
still some interesting information found in the very serious French magazine “science & vie” of September 1924. P49
We talk about this earth-mars conjunction and the author Lucien Rudaux specifies:”that the planets were in similar positions” – something that recurs about every 15 years – and indicates a very close distance of 55,577,000km. The article also talks about the difficulties of observing the earth’s atmosphere…the photos are from the time.

Jenkins & Todd & their devise here : https://www.shorpy.com/node/12482
humm…only electrical cables (in woven fabrics? ) and in 110v had to “pick up” everything that was lying around like RFI:) here we see the radio receiver which was intended for aviation who were therefore probably working on wavelengths 20; 40 and 80m (the antenna was used to lay the clothes for madam :) and the speaker on the table.
I suppose that the transcription of the signal on paper was the ancestor of the Belinograph so we should not be too surprised by the impulses we see on paper. The newspaper article is also interesting since it tells us that the US government had also contact Cuba; Venezuela etc.
A nice page of history.

Aelita is a film UFO that must be seen as innovative but the film must be placed in the context of Soviet Russia at the time. if there is an idea of SF, it is above all an apologia of communism and a critique of the capitalist world but there is also a kind of moral when one understands from where comes the famous message of March shown at the beginning of the film. I do not tell…
@Ljk, & Fred
My copy which looks a tad blurry, has a couple of interesting things.
1. The plans for the rocketship look rather like the Tsiolkovsky design in shape. [The actual inside set [shed?] does look ridiculous.]
2. As the ship speeds away from Earth, at least there are no stars in the sky. Unusual for SciFi films, even the fairly accurate 2001: ASO.
I will say that while the Russians/Soviets were pushing their revolution (about 5 years before the film was made), conditions looked rather bleak. Compare this to the USA which was doing fairly well at the time. The UK didn’t fare quite so well after WWI ended, but it wasn’t in the mess the Soviet Union was at the time. It was the Great Depression starting in 1930-1932 when Western economies went off the rails and Communism was seen at the time as a viable option to Capitalist economies. But since that didn’t happen until after the movie was made, I’m not clear why the Russian people were so enamored of the revolution, at least in terms of their standard of living. Was it so bad for most people that even this post-revolution economy was an improvement?
Rewatching this film after so many years, I was struck by some of the parallels to Fritz Lang’s “Metropolis” (1927) five years later.
Despite the message that the protagonists gave up spaceflight to focus on Earth, a decade or so later, Russian and Eastern European films were very much pushing the message of Cosmism and the successes of Communism.
Perhaps for reasons similar to why thousands of Soviet citizens mobbed Stalin’s casket at his funeral in acts of near worship, despite the fact that he imprisoned and murdered more of his own people than Hitler did in WW2.
Like many throughout history, the Russians suffering under the Czar hoped the new politics – especially the kind that says it is for putting the working class first – would change their lives for the better.
In addition, we often hear first and only from the victors, who of course want everyone to believe they are right and that everything is just peachy under their thumbs.
As for those who think staying on Earth forever is humanity’s ultimate destiny – just ask the dinosaurs how that worked out for them.
Dinosaurs had a pretty good run, surviving as a group for about 165 my. Arguably the avian dinosaurs, continuing as birds managed another 65 million years. How long have we humans had? More importantly, how long have we got left?
Longevity isn’t the criterion I would use for grading species. If we last another million years in some form but have settled in space and around other star systems, creating an immense base of knowledge and art, I think that would be very valuable in itself, more so assuming that an alien species in our footsteps could build on our works and reach new cultural highs.
@Alex
Paul will allow me a little page of history as a French disappointed Slavic :
> I’m not clear why the Russian people were so enamored of the revolution
Except for the enthusiasm of 1917, they were not. Let us recall that Europe was in war; the October revolution was then perceived as a way out towards peace in a new world. But from the 1920s and the beginning of repression (“purges”) the enthusiasm of the people fell. They had to — pretend — to survive in one of the worst political regimes that was put in place by Stalin.
As for the bourgeoisie of “white Russians” they were not more because they wanted to keep their privileges: imagine that at the time you had to suddenly share your house with 3; 4 6 families ! That is why “white Russians” emigrated to Paris or Germany in the 1910s before being massacred.
The rural and strongly believing Russian people did not have the capacity to perceive these things. he was promised “a better world” he could only hope. And if that was not enough, the propaganda and violence of the NKVD then the deportation to the Gulag quickly put the most reluctant to step. Soljenistyne explains it very well in “the archipelago”. It must be understood that 1) they had only a worldview 2) no way to communicate with the outside 3) they had no choice.
>at least in terms of their standard of living
the communist world was based on this belief of a “new world” of “new man”; of “new realism” etc. After 800 years of tsarism and serfdom, This propaganda spread in the minds of the people by Lenin from the end of the 19th century worked perfectly and even for a long time. From the 1920s to the 1960s – after the Khrushchev report – even the French intelligentsia was fooled: I think of our two actors Yves Montant & Simone Signoret fervent communist militant who tore their cards of the “party” After the revelations of the 20th Congress of the Communist Party of the Soviet Union.
The Soviet world was a closed system, locked. (see what Pasternak’s editor did to publish Dr Zhivago!) it was even worse under Stalin; we learn about it today… It raises the question of the diffusion of technological ideas in such a system.
>Was it so bad for most people that even this post-revolution economy was an improvement?
Yes it was: the Russian peasant could feed himself properly with the products of the farm even under the serfdom. For him, Communism was not welcome because the state took EVERYTHING from him for the Kolkhoze. Negation of private property in all its forms, even his cow became state property overnight (imagine a Texan owner who Washington would confiscate all his horses) The Russian city worker saw an improvement in his living standards and infernal working conditions, so he embraced ideology. The upper middle class lived very well and had no desire for communism. It must also be understood that no one knew what this “new world” would be; it was only idealized. It was not an evolution of society but a true violent destruction of the old world (rich or poor) to create something else. there was no place for Thought.
>the parallels to Fritz Lang’s “Metropolis”
That’s right but F. Lang imagined a futuristic world to criticize the technology while the innovation presented in “Ealita” is only the propaganda of power for this “new world” that every Russian “patriot” had to reach. However, the film questions illusions. I still do not reveal the end of the film but review it and look for where Aelita’s message comes from;)
what is interesting is that the idea of surpassing oneself, in the positive sense of emulation, has totally drifted into the Soviet world to lead to the worst -they have indeed surpassed themselves in number of deaths! ) whereas Tsiolkovky and many others had truly…revolutionary ideas that could have been exploited. In northern America, emulation worked much better with the population [for space conquete] probably because of prosperity and the absence of quasi-constraints. We could also compare it to China…but I’ll stop there.
Fred, of course. Always glad to oblige such a good correspondent.
Hi Paul,
It is always a pleasure to read your articles that are both technical and dream-like. The feedback is good and I learned a lot from all of you. Thank you. In France, the general public (<1%) is limited to endless comparisons of materials or discussions of little interest. On the other hand if we have some good "vulgarisateur" (the most famous here was H. Reeves) professional astronomy and technical industry remains closed environments. I am always pleasantly surprised to see on the site of NASA that there are astro games for little ones, this initiation allows vocations. It is also interesting to exchange a European vision and a North American vision. (you could send my email to Henry or Alex if they wish)
I have never been to the USA, just twice in Canada, but I must say that I would like to meet you and see your famous telescope & why not the SETI team ! I hope you will forgive me my mistakes in English, the automatic translators give me surprises and…I drew too many rockets in English class :)
I will look forward to the chance to meet you one of these days, Fred. Thank you for your continuing contributions to the site. You may want to try to make the Interstellar Research Group’s upcoming meeting in Luxembourg:

The deadline for abstracts is almost over, but you could certainly attend and meet many names who appear in these pages. I wish I could c.ome but I cannot travel just now. Keep an eye on irg.space for more information
Thank you, Paul. It’s not far from my home, I’ll check…
For a fictional viewpoint of this period after the October Revolution, I recommend the TV miniseries “A Gentleman in Moscow” based on the Amor Towles novel.
The novel is just superb. I haven’t seen the TV series, but Amor Towles is a terrific writer. His latest, Table for Two is likewise a gem, though a much different kind of work.
Jenkins & Todd worked with a receiver on ~6m wavelength or ~54.5 khz therefore in LF. Here page 23, an article that talks about the experience. We also learn that Todd had proposed a kind of light emitter to Mars formed by a mine crater filled with mercury in which there would be a light source…
http://www.bigear.org/CSMO/PDF/CS04/cs04all.pdf
Two other points are interesting and reflect the state of mind of the time: on the pictures of the graph, Todd writes that he “granted the receiver as much as possible”…they assumed therefore that the Martians would communicate on one frequency or it would be enough to tune ! (I imagine the SETI point today the radiotelescope, press the button of the filter DSP make a coffee and have E.T on live…it would be too easy :)
but more importantly, Todd & Jenkins were — listening — (it’s a receiver and not an emitter) so they assumed technologically advanced worlds. It will also be noted that this was obviously no problem for the army or government to chat quietly with March in 1924 while a few decades later there will be a violent controversy about whether or not to communicate with other civilizations E.T
a look well we can actually see faces lying and profile on the band of the top…I also see little pigs : https://ibb.co/n1kSYCM
What is really astonishing about this article is how limited and provincial our ideas about SETI were only a hundred years ago. A hundred years is nothing, just a blip in the history of humanity, not to mention the history of life in the galaxy. In 1924 people actually believed humanoid life on Mars was possible, that they would use radio technology, water their crops with canal water, in other words, they would be roughly analogous to us in biology as well as technical development. These pioneers were not the general public, we’re talking about government and military officials, scientists, radio engineers, etc.
Can you imagine how quaint and parochial our conversations here on Centauri-Dreams (and our learned articles in peer-reviewed publications!) will sound to SETI researchers in 2124? Even if the fundamental questions asked by the SETI community are still unanswered 100 years in the future, surely the questions themselves will be very different than than the ones we wrestle with now. The writings of Sagan and Shklovskii and Drake, from the 1960s, today seem hopelessly full of assumptions and wishful thinking..
Science progresses, even in the total absence of data.
@ Henry
>Science progresses, even in the total absence of data
I would say rather that it is the ideas and mentalities that change over time and advance – or regress – science. It is the good old debate of L. Munford or J. Ellul: is it the Human who creates the Science or the technological world that models the Human ?
I think there is an interaction between the two since the primate took a baton to take the honey in the tree trunk without being stung by bees:) Specificity of the human race ? What about our “Martians” ?
hi, Fred
It is interesting how you have chosen the ‘primitive’ ape-man ancestor as an example to illustrate your point. In the past, we have often depicted these as dumb brutes, crude, shuffling, grunting and barbaric. But archaeological evidence has taught us these creatures took care of their injured and aged fellows, and that they often buried their dead with ceremony and respect. They created works of art and artifacts of symbolic complexity, all hinting at a complex social structure and a philosophical sophistication.
We may be separated in time, and by centuries of biological and cultural evolution, but we also carry their DNA: they were human. It is not surprising we share much with them, and if it were possible to meet them face-to-face I am sure we would recognize them as our kin.
You may have noticed that one of the major themes in my comments here on C-D is that ETI, if it exists at all, will share no common history with us except perhaps some very basic biochemical and physical characteristics, and that we are not even capable of fully understanding what all those similarities and differences might be.
My fascination with the POSSIBILITY of extra terrestrial life and intelligence (and I’m not even sure it exists!) is dependent on that they will be very different from us. They will be strange, perhaps even horrifying, but certainly wonderful. I feel a need to understand just how they will differ from us, and how they will be in some ways the same. And I understand also how knowing that will tell me just what it means to be human.
Hello Henry
The idea of the primate/hominid with the stick – the 1st tool – seems to me very representative of the genesis of technology. There is much speculation about what it will be tomorrow but less about where it comes from ?
Will other worlds, if they exist, develop themself on this same basis? Not sur and I agree with you.
Being “human” is extension and constraint within a particular environment including the available body-mind complex and the matter-energy, time and space within which it functions.
For all we know, cetaceans may consider us rather stupid in spite of our remarkable physical endowment that includes four limbs. And their cognition may be beyond our ken.
“So long, and thanks for all the fish” as they depart the Earth before it is destroyed by the Vogon constructor fleet.

If you have a copy, “Mars and the Mind of Man” is worth looking at for its historical value. It is written by each of the participants at the meeting at Caltech just prior to the Mariner 9 mission’s arrival at Mars, with a postscript by each of the participants: Ray Bradbury, Arthur C. Clarke, Bruce Murray, Carl Sagan, and Walter Sullivan.
Sagan still seems to have hope that life, or a very different type, might still be found on Mars now that the seasonal color variations proved to be dust, not vegetation.
The Viking landers were the last to try to find life directly. After possibly one ambiguous experiment, NASA abandoned that approach and spent the following decades “following the water”. We still have not directly looked for life again on Mars. I hope future missions are not so timid, especially the [eventually!] upcoming ExoMars mission later this decade. It would be an irony if the Europa Clipper mission found evidence of life there first.
Oh, I definitely have a copy of Mars and the Mind of Man! A wonderful book and snapshot of exploring the Red Planet right before and after Mariner 9. I also definitely agree that NASA needs to be much more bold in finding extraterrestrial life. If they won’t, someone else certainly will.

The following comes from Mars Pioneers …
(1928 October 24):
Briton Gets ‘Messages’ After Radio to Mars,
But He Says He Must Wait to Decode Them
By The Associated Press.
CHISWICK, England, Wednesday, Oct. 24.—
Dr. Mansfield Robinson, who sent a wireless message to Mars early this morning, said at 4 o’clock that he had received certain messages, but would have to wait until they were decoded.
Dr. Robinson was at the laboratory of his scientific friend, Professor A. M. Low, trying to pick up signals from Mars on a high-powered radio set.
LONDON, Wednesday, Oct. 24 (AP).— Dr. Robinson, who is a psychic devotee, addressed his wireless dispatch to Compararu, the big-eared woman of Mars, through the big station at St. Albans.
The call was sent out at 2:15 A. M. and the engineers at St. Albans listened on a 30,000-meter wave length for a reply, but up to 3:30 had received none.
Since, however, communication between London and St. Albans at this hour of the morning is about as easy as communication with Mars, it might be premature to say that the listeners have nothing to report.
It was understood that Dr. Robinson also intended to listen for a reply at his home in Royden, Hertfordshire. The Daily Express sent a reporter there late last night, but he found the house dark. On the front door was pinned a paper bearing the word ‘‘Out.” Nothing daunted, the reporter knocked at the door until Mrs. Robinson came to it and said:
“If you have come about that message, I know nothing. I have refused to have any experiments in the house while I am in it.
“My husband has gone to London. I do not know whether anybody there will encourage him, but there will be no foolishness around this house.”
Then she closed the door.

Technosignatures: Effect Of COVID-19 Global Lockdown On Our Moon
By Keith Cowing
Status Report
MRAS
October 1, 2024
Systematic investigation of lunar night-time temperatures can possibly be thought as a stable platform to study Earth’s radiation budget and climate change as advocated earlier by several researchers.
In this study, we report an interesting observation possibly of changing Earth’s climate as experienced by the Moon, utilizing a rare and novel context of COVID-19 global lockdown. Lunar night-time surface temperatures of six different sites on the Moon’s nearside were analysed during the period 2017–2023.
Results showed an anomalous dip in the lunar night-time surface temperatures for all the sites during April–May 2020, the strict COVID-19 global lockdown period, when compared to the values of the same period during the previous and subsequent years.
Since the terrestrial radiation has also showed a significant reduction during that time, the anomalous decrease observed in lunar surface temperatures is attributed to the COVID-19 global lockdown effect.
Therefore, our study shows that the Moon has possibly experienced the effect of COVID-19 lockdown, visualized as an anomalous decrease in lunar night-time surface temperatures during that period.
These results can be substantiated further from Moon-based observatories in future, thereby making them potential tools for observing Earth’s environmental and climate changes.

Scientists seeking life on Mars heard a signal that hinted at the future
In 1924, a radio receiver built for the battlefields of World War I tested the idea that humans were not alone in the solar system, heralding a century of searches for extraterrestrial life. (Señor Salme/The New York Times)
By Becky Ferreira
At sunset on a late summer weekend in 1924, crowds flocked to curbside telescopes to behold the advanced alien civilization they believed to be present on the surface of Mars.
“See the wonders of Mars!” an uptown sidewalk astronomer shouted in New York City on Saturday, Aug. 23. “Now is your chance to view the snowcaps and the great canals that are causing so much talk among the scientists. You’ll never have such a chance again in your lifetime.”
That weekend, Earth and Mars were separated by just 34 million miles, closer than at any other point in a century. Although this orbital alignment, called an opposition, occurs every 26 months, this one was particularly captivating to audiences across continents and inspired some of the first large-scale efforts to detect alien life.
“In scores of observatories, watchers and photographers are centering their attention on that enigmatic red disk,” journalist Silas Bent wrote on Aug. 17, 1924. He added that it might be the moment to “solve the disputed question of whether supermen rove his crust, and whether those lines, which many observers say they have seen, really are irrigation canals.”
Scientists plotted for years to make the most of the Martian “close-up.” To aid the experiments, the U.S. Navy cleared the airwaves, imposing a nationwide period of radio silence for five minutes at the top of each hour from Aug. 21 to 24 so that messages from Martians could be heard. A military cryptographer was on hand to “translate any peculiar messages that might come by radio from Mars.”
Then, lo and behold, an astonishing radio signal arrived with the opposition.
A series of dots and dashes, captured by an airborne antenna, produced a photographic record of “a crudely drawn face,” according to news reports. The tantalizing results and subsequent media frenzy inflamed the public’s imagination. It seemed as if Mars was speaking, but what was it trying to say?
“The film shows a repetition, at intervals of about a half-hour, of what appears to be a man’s face,” one of the experiment’s leaders said days later.
“It’s a freak which we can’t explain,” he added.
A century has elapsed since the Mars mania of 1924, but the source of that strange signal remains a mystery. The original paper record is presumed lost, though digital copies have survived, ensuring that the crudely drawn face continues to stare out at us across time.
But the story of the 1924 Mars opposition is as much about the audacity of attempting a detection of extraterrestrial life as it was about the murky outcomes. Some things have changed, such as our technologies for studying the cosmos. But what endures is that sneaky feeling that we are not alone in the universe.
“We need some cosmic company out there, whether it’s in the form of gods or extraterrestrials,” said Steven Dick, an astronomer and former NASA chief historian who has written about humanity’s interest in aliens. “People go out and look at the night sky, and there’s all these thousands of stars, and they think, ‘Surely we can’t be the only ones.’”
“That’s a nice thought, but it’s not science,” he added.
The science, so far, includes the discovery that the basic building blocks of life are widely distributed in our galaxy. Researchers have also spotted thousands of planets orbiting other stars, including worlds roughly the size of Earth. And they know Mars was once habitable, a place with gushing rivers, freshwater lakes and substantive skies. They have even discovered possible biosignatures there, both from the past and in the present, although there is still no slam-dunk evidence of aliens there, or anywhere.
Humanity has learned so much about our world, and others beyond it, in a century. But that progress flowed in part from the attitudes that defined the 1924 Mars opposition as an important milestone in the history of our search for aliens — a moment when the physical proximity of two worlds exposed a deeper yearning for cosmic connection, and the will to actively seek that contact through scientific innovation, that is still very much with us today.
In the expansive collections of the Henry Ford Museum of American Innovation near Detroit, there is a boxy artifact that was designed for the trenches and battlefields of World War I. In August 1924, it wound up serving as an interplanetary communications prototype.
Kristen Gallerneaux, a sonic historian and a curator of communication and information technology at the Henry Ford, is a caretaker of many technological relics. But they have a special fondness for the device, a Navy-type model SE 950 radio, and its historic role as a would-be alien-detector.
“It is exactly my kind of object,” Gallerneaux said. “It feels like a buried history to me.”
Manufactured on March 26, 1918, by the National Electrical Supply Co., the hardy portable radio was designed to support troops in combat, but this unit was never battle tested. It ended up, instead, in the Washington laboratory of Charles Francis Jenkins, an inventor who played a key role in the development of television.
It might have been used in many postwar experiments, but its golden hour arrived before the 1924 Mars opposition when astronomer David Peck Todd enlisted Jenkins to solve a problem that still animates the community involved in the search for extraterrestrial intelligence: If messages from intelligent aliens are wafting through space, how might we capture them?
The astronomer and the inventor cobbled together an answer. During the opposition, a dirigible was launched from the U.S. Naval Observatory in Washington to an altitude of just under 2 miles. It carried an antenna, pointed at Mars, that relayed signals back from its aerial position to the SE 950 radio in Jenkins’ lab.
The data was then fed into the inventor’s “Radio Camera,” which converted radio signals into optical flashes that left imprints on a 38-foot-long roll of photographic paper. It was this process that produced the repeating pattern that many viewers interpreted as a face.
As some people longed for interplanetary validation, others worried about the wisdom of communicating with alien neighbors. A 1919 editorial titled “Let the Stars Alone” suggested that humans could be “unprepared” for “superior intelligences.”
Imagine if humans were to “cheerfully wireless to Mars, ‘two plus two is four,’ and Mars answers, ‘no, you’re wrong,’” the editorial posited. “What are you going to do about it?”
The opposition was an opportunity to road-test these competing ideas. From a hilltop in England, a group recorded “strange noises” that “could not be identified as coming from any earthly station.” In Vancouver, British Columbia, a signal “led radio experts here seriously to consider the theory that Mars is trying to ‘tune in.’”
Ultimately, the opposition produced no lasting evidence of Martian life, a result that vindicated scientific skeptics who had spent years pointing to the red planet’s absence of water or breathable air. Such truth seekers were often mocked.
“Some great talkers conclude that Mars must be uninhabitable,” French astronomer Camille Flammarion, a firm believer in intelligent Martians, wrote in March 1924. “This is not the reasoning of philosophers, but of fish,” he continued, comparing skeptics to fish who believe life out of water is impossible.
Today, a host of sophisticated technologies are revealing insights about the universe that nobody could have imagined 100 years ago. Rovers trundle across Mars, telescopes resolve chemicals in the clouds of faraway exoplanets and observatories scan space for messages across millions of radio frequencies.
But with regard to alien life, all of this ingenuity and investment has delivered the same basic result as that inscrutable readout of dots and dashes, mediated by a wartime radio born too late for combat, captured in 1924.

SIGNALING TO MARS BY BRAZILIAN RADIO
Dr. Robinson of London Repeats Effort
to Communicate With “Inhabitants” of Planet.
Special Cable to The New York Times.
SAO PAULO, Brazil, Dec. 15.—Beginning tonight at 11:30 another attempt will be made to communicate with Mars.
Dr. Richard Mansfield Robinson, who has made several unsuccessful attempts, including an experiment at the English Rugby radio station, is now using the sending station of the Companhia Radio Telegraphica Brasileira, in which the Radio Corporation of America has a large interest. The station is located on the outskirts of Rio de Janeiro. It will begin tonight and end Sunday at midnight.
The station will send signals with a potency of 500 kilowatts and with waves more than 21,000 meters long. Antennae two and one-half kilometers long are supported by twelve towers 250 meters high.
It will send messages with a call letter.
The text is “God is love; from earth to Mars.” The receiving station is prepared to receive a response.
Long waves with four seconds between the signals will be used because Dr. Robinson believes the Martians will understand better if the transmission is slow.
