“Listen now for the sound that forevermore separates the old from the new!”*…
Telstar
Newton Minow, famed Chairman of the FCC during the Kennedy Administration, recalled visiting NASA with the President, who asked him about a satellite they were shown:
I told him that it would be more important than sending a man into space. “Why?” he asked. “Because,” I said, “this satellite will send ideas into space, and ideas last longer than men.”
Greg Roberts, a retired astronomer and ham radio operator (ZS1BI in Cape Town) has been observing and recording the sounds broadcast by satellites since 1957. He’s collected his recordings so that one can hear “ideas traveling through space,” for example, Telstar.

As we look to the skies, we might recall that it was on this date in 1781 that English astronomer William Herschel detected every schoolboy’s favorite planet, Uranus, in the night sky (though he initially thought it was a comet:; it was the first planet to be discovered with the aid of a telescope. In fact, Uranus had been detected much earlier– but mistaken for a star: the earliest likely observation was by Hipparchos, who in 128BC seems to have recorded the planet as a star for his star catalogue, later incorporated into Ptolemy’s Almagest. The earliest definite sighting was in 1690 when John Flamsteed observed it at least six times, cataloguing it as the star 34 Tauri.
Herschel named the planet in honor of his King: Georgium Sidus (George’s Star), an unpopular choice, especially outside England; argument over alternatives ensued. Berlin astronomer Johann Elert Bode came up with the moniker “Uranus,” which was adopted throughout the world’s astronomical community by 1850.
