The first face from Mars was received in a repeating pattern radio signal (described by some as dashes in groups of four) in 1924's Mars closest approach to Earth, that converted to an image looked like the strip below.
(Dr. Davis Todd, assistant Leo Stevens, and Percibal Lowell, Nikola Tesla)
During the years 1899-1924 three experimental scientists, Nikola Tesla, Guglielmo Marconi, and David Todd (working independently of each other) observed laboratory data and related phenomenon which suggested the possibility that they were monitoring interplanetary communications. During the same period (199-1924) the Russian theorist Konstantin Tsiolkovsky deduced a model of an intelligence existing independently of terrestrial influence.
Monitoring centered on Saturday night, when the two planets were at their closest. However, strange signals were reported even before the nearest approach of the planet. Radio operators in Vancouver reported on Thursday that they were receiving a series of "four groups of dashes in groups of four". Both the form and origin of the strange signals were unidentified, and a close watch was promised. In London a specially constructed 24-tube set picked up "harsh notes" of an unknown origin. WOR engineers in Newark, New Jersey reported similar sounds at nearly the same wavelength. A Bostonian reported a strange ringing, ending with an abrupt "zzip"..
Interesting research Mars rock, are you aware and if so what’s your opinion about the radio signals recorded in the mid 1920’s coming from Mars in one of its closest approaches to earth, and which, according to some stories contained irrefutable evidence of artificiality encoded in?
Of course the discoverers, although they fought hardly to have the news out, were target of a smear campaign and that was the end of it
