"Science fiction represents the modern heresy and the cutting edge of speculative imagination as it grapples with Mysterious Time---linear or non-linear time."
- Frank Herbert

| An 'ad' on the lunar surface that can be seen by its audience on Earth. |
It started out as a perfectly innocent experiment, meant to add to the store of human knowledge. Just an extension of an experiment tried on Earth, or rather in the atmosphere high above the surface. Sodium ejected at a high altitude dispersed in a scientifically useful manner.
| "...The
sodium cloud will be completely invisible while it’s rising up through
the darkness of the Moon’s shadow.
Then, quite suddenly, it will flash
into brilliance as it enters the sun’s
rays, which are streaming past over
our heads right now as we stare
up into space. No one is quite sure
how bright it will be, but it’s a
pretty safe guess that you’ll be able
to see it in any telescope bigger
than a two-inch. So it should just
be within the range of a good pair
of binoculars...”
Then a sudden yellow glow began to spread across the sky, like a vast and unwavering aurora that became brighter even as we watched. It was as if an artist was sprawling strokes across the stars with a flame-filled brush. And as I stared at those strokes, I suddenly realized that someone had brought off the greatest advertising coup in history. For the strokes formed letters, and the letters formed two words — the name of a certain soft drink too well-known to need any further publicity from me. How had it been done? The first answer was obvious. Someone had placed a suitable cut stencil in the nozzle of the sodium bomb, so that the stream of escaping vapor had shaped itself to the words. Since there was nothing to distort it, the pattern had kept its shape during its invisible ascent to the stars. I had seen sky-writing on Earth, but this was something on a far larger scale. The next morning, every newspaper on the planet carried that famous photo of the crescent Moon with the luminous slogan painted across its darkened sector. The letters were visible, before they finally dispersed into space, for over an hour. By that time the words were almost a thousand miles long, and were beginning to get blurred. |

Thanks to Winchell Chung for suggesting this item in a comment sixteen years ago!
Compare to atmospheric advertising from In the Year 2889 (1889) by Jules Verne, the Orbiting Casino Advertising Sign from One Against The Legion (1939) by Jack Williamson and the permanent skywriting from Soap Opera (1953) by Alan Nelson.

'Deveet unhooked his catch and laid it on the bank beside him. It was a metal fish.'
'...waldoes in the screen followed in exact, simultaneous parallelism.'
'Seen close it was not completely flexible, but made instead of pivoted and smoothly finished segments.'
'...great rectangular slabs of muscle, slung into a rectangular frame.'
'If the biological robots were not living creatures, they were certainly very good imitations.'
"Everybody and his dog, it seemed, wanted to live out in the country; transportation and communication were no longer isolating factors."
