Lalande 25372 is a Spectral Class M star, a faint red dwarf not visible to the naked eye from Earth, Sol. Lalande 25372 lies fifteen point nine light years from Sol, about fifteen degrees north of the celestial equator and not quite opposite the vernal equinox. It has planets, but this does not make Lalande 25372 unique. Like most of the planets found in space, neither mad dogs nor Englishmen would have anything to do with them—willingly. They are suitable only for the hapless wight whose erring foot has unhappily landed on the tender official toe.
The planet Flatbush, Lalande 25372, received its name from an obscure medieval reference to a form of punishment known as "Walking a beat in Flatbush," if we are to believe MacClelland's authoritative volume The Origin of Place Names.
Observed through the multipane window of the Station, Flatbush, Lalande 25372, was a pleasant enough planet, provided one could ignore the fact that there was not a sign nor trace of vegetation from the Installation Building to the horizon. A couple of hundred yards from the building there was a pleasant looking lake. The lake was indeed water, but it contained dissolved substances that would have poisoned a boojum snark. The warm wind of Flatbush rippled the surface of the lake, but no square yard of sail would be hoisted until someone first built a gas mask that would filter out the colorless gases that turned silver black. Fluffy clouds floated across the sky, but they rained down a mess that etched stainless steel.
Out There, near the perimeter of Man's five-parsec range of operations, subelectromagnetic detector beams scoured the sky. Taking the most pessimistic standpoint—the least possible combinations of Nature's infinite variety of environment—Nature's own profligacy with life-forms still demanded that somewhere, Out There, another race was plying the spaceways.
Someday this hypothetical race was certain to touch wings with mankind.
When that took place it was the duty of the Bureau of Operations to detect them, to intercept them, and to warn the men of Earth, Sol, that Mankind was no longer alone. The fact that the subelectromagnetic detecting beams had been sweeping space for a couple of hundred years without detecting anything had no bearing on the future. The beams must be maintained so long as a human man remained alive in space.
In addition to the detector beams, the outlying planets carried astrogation beacons. They were subelectromagnetic lighthouses, so to speak, that rang across space with known direction and ranging telemetered signals. Someday, Man hoped to fill the space lanes with spacecraft and the planets with interstellar commerce.
Someday there might be another Marie Celeste plying its course with its crew inexplicably missing. But if this ever happened, it was not going to happen without the Space Service knowing precisely how many and which spacecraft were operating through that volume of space before, during, and after D-for-Disaster Day and M-for-Mysterious Minute.
The equipment, of course, was automated to modern perfection, with multi-lateral channels that would take over in case of component failure. Its factor of reliability was well above six or seven nines of perfection. But to admit that this perfection was adequate would have deprived the Space Service of a convenient minor penal detail to take care of brash junior officers. Manning such a station provided the junior officer with a wealth of time to contemplate his sins, and to mend his evil ways.
