Missile Gap

The disk is vast — so huge that it defies sanity. Some estimates give it the surface area of more than a billion earths. Exploration by conventional means is futile: hence the deployment of the NP-101 Persephone drone, here seen making a proving flight over land mass F-42. The NP-101 is a reconnaissance derivative of the nuclear-powered D-SLAM Pluto missile that forms the backbone of our post-Move deterrent force. It is slower than a strategic D-SLAM, but much more reliable: while D-SLAM is designed for a quick, fiery dash into Soviet territory, the NP-101 is designed to fly long duration missions that map entire continents. On a typical deployment the NP-101 flies outward at thrice the speed of sound for nearly a month: traveling fifty thousand miles a day, it penetrates a million miles into the unknown before it turns and flies homeward. Its huge mapping cameras record two images every thousand seconds, and its sophisticated digital computer records a variety of data from its sensor suite, allowing us to build up a picture of parts of the disk that our ships would take years or decades to reach. With resolution down to the level of a single nautical mile, the NP-101 program has been a resounding success, allowing us to map whole new worlds that it would take us years to visit in person.

At the end of its mission, the NP-101 drops its final film capsule and flies out into the middle of an uninhabited ocean, to ditch its spent nuclear reactor safely far from home.

A bull's-eye diagram. The centre is a black circle with a star at its heart; around it is a circular platter, of roughly the same proportions as a 45 rpm single.

A rough map of the disk. Here is the area we have explored to date, using the NP-101 program.

(A dot little larger than a sand grain lights up on the face of the single.)

That dot of light is a million kilometers in radius — five times the distance that used to separate our old Earth from its moon. (To cross the radius of the disk, an NP-101 would have to fly at Mach Three for almost ten years.) We aren't even sure exactly where the centre of that dot lies on the disk: our highest sounding rocket, the Nova-Orion block two, can barely rise two degrees above the plane of the disk before crashing back again. Here is the scope of our knowledge of our surroundings, derived from the continental-scale mapping cameras carried by Project Orion:

(A salmon pink area almost half an inch in diameter lights up around the red sand grain on the face of the single.)

Of course, cameras at an altitude of a hundred thousand miles can't look down on new continents and discern signs of Communist infiltration; at best they can listen for radio transmissions and perform spectroscopic analyses of the atmospheric gasses above distant lands, looking for gasses characteristic of industrial development such as chlorofluorocarbons and nitrogen oxides.

This leaves us vulnerable to unpleasant surprises. Our long term strategic analyses imply that we are almost certainly not alone on the disk. In addition to the Communists, we must consider the possibility that whoever build this monstrous structure — clearly one of the wonders of the universe — might also live here. We must contemplate their motives for bringing us to this place. And then there are the aboriginal cultures discovered on continents F-29 and F-364, both now placed under quarantine. If some land masses bear aboriginal inhabitants, we may speculate that they, too, have been transported to the disk in the same manner as ourselves, for some as-yet unknown purpose. It is possible that they are genuine stone-age dwellers — or that they are the survivors of advanced civilizations that did not survive the transition to this environment. What is the possibility that there exists on the disk one or more advanced alien civilizations that are larger and more powerful than our own? And would we recognize them as such if we saw them? How can we go about estimating the risk of our encountering hostile Little Green Men — now that other worlds are in range of even a well-equipped sailboat, much less the Savannah-class nuclear powered exploration ships? Astronomers Carl Sagan and Daniel Drake estimate the probability as high — so high, in fact, that they believe there are several such civilizations out there.

We are not alone. We can only speculate about why we might have been brought here by the abductors, but we can be certain that it is only a matter of time before we encounter an advanced alien civilization that may well be hostile to us. This briefing film will now continue with an overview of our strategic preparations for first contact, and the scenarios within which we envisage this contingency arising, with specific reference to the Soviet Union as an example of an unfriendly ideological superpower…
