The race didn't end because the ship and asteroid were no longer constantly accelerating. Whatever the general thought of it and however he modified his own plans, as far as the accidentals were concerned the emphasis had merely shifted. Exploration. It didn't matter who got to the system first—it was who found the inhabited or inhabitable planets.
The ship had slightly more speed even when, by mutual consent, both cut the strength of the drive. Slowly it pulled level and then began to creep ahead. But the scanner nullified the advantage. The astronomical equipment of the ship, superior though it was, was not adequate to observe the planets in detail from this distance. Before the ship could locate planets and catalogue the characteristics it would ultimately have to slow down and waste days or weeks searching the specks of light to decide which were worth closer investigation.
With the mass sensitive scanner there was no such problem. Six planets for Alpha and seven for Proxima with, for a while, the possibility that one or two more might be on the far side of the respective suns. Within weeks, relative to the asteroid, much longer for stationary objects, that possibility was eliminated. Six and seven planets there were and no more.
In one respect the scanner wasn't perfect. Nona was shown where it failed to perform satisfactorily and, after looking it over with mild curiosity, took it completely apart, altering a number of circuits. When she reassembled it again it had exactly the same limitations.
Jordan switched it on and brought the planet in focus. He changed the dial setting and the image blurred, scattering a coruscating rainbow of brilliant light. Once again he patiently adjusted the dials and the planet returned to normal. "That's as close as we can get," he said. "I'd estimate about fifty thousand miles out."
"Try the fourth planet, the Saturn type," suggested Docchi.
Minus rings but with several satellites a large planet replaced the smaller one they had been looking at. After vainly trying to get closer Jordan gave his opinion. "A hundred and fifty thousand miles from the surface. This thing's mass sensitive, that's all—proportional to the mass. It won't resolve an image close to the surface of a planet. Notice that we couldn't get nearer than a few million miles of the sun—but we could slide right into a little thing like a ship."
Reluctantly Docchi nodded. "We'll have to be satisfied with it as it is. Nevertheless I think it can be made to approach the surface of any mass, even the sun."
"Nona couldn't do it," said Jordan.
Docchi smiled. "I think she's more interested in her husband at the moment. Besides, what did she have to work with? Odds and ends of parts that really aren't suited for what they have to do. It would be different if she had an unlimited supply of gravity generating parts, or could get what she needs made to order."
