Rama could not possibly be made of condensed matter. No star-sized mass could penetrate so deeply into the solar system without producing disturbances which would have betrayed it long ago. The orbits of all the planets would have been affected; that, after all, was how Neptune, Pluto and Persephone had been discovered. No, it was utterly impossible for an object as massive as a dead sun to sneak up unobserved.

In a way, it was a pity. An encounter with a dark star would have been quite exciting.

While it lasted…

3. Rama and Sita

The extraordinary meeting of the Space Advisory Council was brief and stormy. Even in the twenty-second century, no way had yet been discovered of keeping elderly and conservative scientists from occupying crucial administrative positions. Indeed, it was doubted if the problem ever would be solved.

To make matters worse, the current Chairman of the SAC was Professor (Emeritus) Olaf Davidson, the distinguished astrophysicist. Professor Davidson was not very much interested in objects smaller than galaxies, and never bothered to conceal his prejudices. And though he had to admit that ninety per cent of his science was now based upon observations from space-borne instruments, he was not at all happy about it. No less than three times during his distinguished career, satellites specially launched to prove one of his pet theories had done precisely the opposite.

The question before the Council was straightforward enough. There was no doubt that Rama was an unusual object—but was it an important one? In a few months it would be gone for ever, so there was little time in which to act. Opportunities missed now would never recur.

At rather a horrifying cost, a space probe soon to be launched from Mars to beyond Neptune could be modified and sent on a high-speed trajectory to meet Rama. There was no hope of a rendezvous; it would be the fastest fly-by on record, for the two bodies would pass each other at two hundred thousand kilometres an hour. Rama would be observed intensively for only a few minutes—and in real close-up for less than a second. But with the right instrumentation, that would be long enough to settle many questions.
