2001_ A Space Odyssey - Arthur C. Clarke [25]
“That’s all I have to say. Now I’m ready for your report.”
He walked back to his seat; the Administrator said, ‘Thank you very much, Dr. Floyd,” and nodded, rather brusquely, to his Chief Scientist. On cue, Dr. Michaels walked up to the rostrum, and the lights faded out.
A photograph of the Moon flashed onto the screen. At the very center of the disk was a brilliant white crater ring, from which a striking pattern of rays fanned out. It looked exactly as if someone had hurled a bag of flour at the face of the Moon, and it had spattered out in all directions.
“This is Tycho,” said Michaels, pointing to the central crater. “On this vertical photograph Tycho is even more conspicuous than when seen from Earth; then it’s rather near the edge of the Moon. But observed from this viewpoint — looking straight down from a thousand miles up — you’ll see how it dominates an entire hemisphere.”
He let Floyd absorb this unfamiliar view of a familiar object, then continued: “During the past year we have been conducting a magnetic survey of the region, from a low-level satellite. It was completed only last month, and this is the result — the map that started all the trouble.”
Another picture flashed on the screen; it looked like a contour map, though it showed magnetic intensity, not heights above sea level. For the most part, the lines were roughly parallel and spaced well apart; but in one corner of the map they became suddenly packed together, to form a series of concentric circles — like a drawing of a knothole in a piece of wood.
Even to an untrained eye, it was obvious that something peculiar had happened to the Moon’s magnetic field in this region; and in large letters across the bottom of the map were the words: TYCHO MAGNETIC ANOMALY-ONE (TMA-1). Stamped on the top right was CLASSIFIED.
“At first we thought it might be an outcrop of magnetic rock, but all the geological evidence was against it. And not even a big nickel-iron meteorite could produce a field as intense as this; so we decided to have a look.
“The first party discovered nothing — just the usual level terrain, buried beneath a very thin layer of moon-dust. They sank a drill in the exact center of the magnetic field to get a core sample for study. Twenty feet down, the drill stopped. So the survey party started to dig — not an easy job in spacesuits, as I can assure you.
“What they found brought them back to Base in a hurry. We sent out a bigger team, with better equipment. They excavated for two weeks — with the result you know.”
The darkened assembly room became suddenly hushed and expectant as the picture on the screen changed. Though everyone had seen it many times, there was not a person who failed to crane forward as if hoping to find new details. On Earth and Moon, less than a hundred people had so far been allowed to set eyes on this photograph.
It showed a man in a bright red and yellow spacesuit standing at the bottom of an excavation and supporting a surveyor’s rod marked off in tenths of a meter. It was obviously a night shot, and might have been taken anywhere on the Moon or Mars. But until now no planet had ever produced a scene like this.
The object before which the spacesuited man was posing was a vertical slab of jet-black material, about ten feet high and five feet wide: it reminded Floyd, somewhat ominously, of a giant tombstone. Perfectly sharp-edged and symmetrical, it was so black it seemed to have swallowed up the light falling upon it; there was no surface detail at all. It was impossible to tell whether it was made of stone or metal or plastic — or some material altogether unknown to man.
“TMA-1,” Dr. Michaels declared, almost reverently. “It looks brand new, doesn’t it? I can hardly blame those who thought it was just a few years old, and tried to connect it with the third Chinese Expedition, back in ‘98. But I never believed that — and now we’ve been able to date it positively, from local geological evidence.
“My colleagues and I, Dr. Floyd, will stake our
