Ford shook his head. “I’ve been listening but I could never learn it. I’m not a pilot”
“Huh? How did you get here?”
“Oh. I do have a license, but I haven’t had time to keep in practice. My chauffeur always pilots me. I haven’t figured a trajectory in many years.”
Lazarus looked him over. “And yet you plotted an orbit rendezvous? With no reserve fuel?”
“Oh, that. I had to.”
“I see. The way the cat learned to swim. Well, that’s one way.” He turned back to speak to Libby, was interrupted by Barstow’s voice over the announcing system:
“Five minutes, Lazarus! Acknowledge.”
Lazarus found the microphone, covered the light under it with his hand and answered, “Okay, Zack! Five minutes.” Then he said, “Cripes, I haven’t even picked a course. What do you think, Andy? Straight out from Earth to shake the busies off our tail? Then pick a destination? How about it, Slayton? Does that fit with what you ordered Navy craft to do? “No, Lazarus, no!” protested Libby. “Huh? Why not?”
“You should head right straight down for the Sun.”
“For the Sun? For Pete’s sake, why?”
“I tried to tell you when I first saw you. It’s because of the space drive you asked me to develop.”
“But, Andy, we haven’t got it.”
“Yes, we have. Here.” Libby shoved the satchel he had been carrying toward Lazarus.
Lazarus opened it.
Assembled from odd bits of other equipment, looking more like the product of a boy’s workshop than the output of a scientist’s laboratory, the gadget which Libby referred to as a “space drive” underwent Lazarus’ critical examination. Against the polished sophisticated perfection of the control room it looked uncouth, pathetic, ridiculously inadequate.
Lazarus poked at it tentatively. “What is it?’ he asked. “Your model?”
“No, no. That’s it. That’s the space drive.”
Lazarus looked at the younger man not unsympathetically. “Son,” he asked slowly, “have you come unzipped?”
“No, no, no!” Libby sputtered. “I’m as sane as you are. This is a radically new notion. That’s why I want you to take us down near the Sun. If it works at all, it will work best where light pressure is strongest.”
“And if it doesn’t work,” inquired Lazarus, “what does that make us? Sunspots?”
“Not straight down into the Sun. But head for it now and as soon as I can work out the data, I’ll give you corrections to warp you into your proper trajectory. I want to pass the Sun in a very fiat hyperbola, well inside the orbit of Mercury, as close to the photosphere as this ship can stand. I don’t know how close that is, so I couldn’t work it out ahead of time. But the data will be here in the ship and there will be time to correlate them as we go.”
Lazarus looked again at the giddy little cat’s cradle of apparatus. “Andy … if you are sure that the gears in your head are still meshed, I’ll take a chance. Strap down, both of you.” He belted himself into the pilot’s couch and called Barstow. “How about it, Zack?” “Right now!”
“Hang on tight!” With one hand Lazarus covered a light in his leftside control panel; acceleration warning shrieked throughout the ship. With the other he covered another; the hemisphere in front of them was suddenly spangled with the starry firmament, and Ford gasped.
Lazarus studied it. A full twenty degrees of it was blanked out by the dark circle of the nightside of Earth. “Got to duck around a corner, Andy. We’ll use a little Tennessee windage.” He started easily with a quarter gravity, just enough to shake up his passengers and make them cautious, while he started a slow operation of precessing the enormous ship to the direction he needed to shove her in order to get out of Earth’s shadow. He raised acceleration to a half gee, then to a gee.
Earth changed suddenly from a black silhouette to a slender silver crescent as the half-degree white disc of the Sun came out from behind her. “I want to clip her about a thousand miles out, Slipstick,” Lazarus said tensely, “at two gees. Gimme a temporary vector.” Libby hesitated only momentarily and gave it to him. Lazarus again sounded acceleration warning and boosted to twice Earth-normal gravity. Lazarus was tempted to raise the boost to emergency-full but he dared not do so with a shipload of groundlubbers; even two gees sustained for a long period might be too much of a strain for some of them. Any Naval pursuit craft ordered to intercept them could boost at much higher gee and their selected crews could stand it. But it was just a chance they would have to take … and anyhow, he reminded himself, a Navy ship could not maintain a high boost for long; her mile-seconds were strictly limited by her reaction-mass tanks.
The New Frontiers had no such oldfashioned limits, no tanks; her converter accepted any mass at all, turned it into pure radiant energy. Anything would serve-meteors, cosmic dust, stray atoms gathered in by her sweep field, or anything from the ship herself, such as garbage, dead bodies, deck sweepings, anything at all. Mass was energy. In dying, each tortured gram gave up nine hundred million trillion ergs of thrust. The crescent of Earth waxed and swelled and slid off toward the left edge of the hemispherical screen while the Sun remained dead ahead. A little more than twenty minutes later, when they were at closest approach and the crescent, now at half phase, was sliding out of the bowl screen, the ship-to-ship circuit came to life. “New Frontiers!” a forceful voice sounded. “Maneuver to orbit and lay to! This is an official traffic control order.”
Lazarus shut it off. “Anyhow,” he said cheerfully, “if they try to catch us, they won’t like chasing us down into the Sun! Andy, it’s a clear road now and time we corrected, maybe; You want to compute it? Or will you feed me the data?”
“I’ll compute it,” Libby answered. He had already discovered that the ship’s characteristics pertinent to astrogation, including her “black body” behavior, were available at both piloting stations. Armed with this and with the running data from instruments he set out to calculate the hyperboloid by which he intended to pass the Sun. He made a half-hearted attempt to use the ship’s ballistic calculator but it baffled him; it was a design he was not used to, having no moving parts of any sort, even in the exterior controls. So he gave it up as a waste of time and fell back on the strange talent for figures lodged in his brain. His brain had no moving parts, either, but he was used to it.
Lazarus decided to check on their popularity rating. He switched on the ship-to-ship again, found that it was still angrily squawking, although a little more faintly. They knew his own name now-one of his names-which caused him to decide that the boys in the Chili must have called traffic control almost at once. He tut-tutted sadly when he learned that “Captain Sheffield’s” license to pilot had been suspended. He shut it off and tried the Naval frequencies … then shut them off also when he was able to raise nothing but code and scramble, except that the words “New Frontiers” came through once in clear.
He said something about “sticks and stones may break my bones-” and tried another line of investigation. Both by long-range radar and by paragravitic detector he could tell that there were ships in their neighborhood but this alone told him very little; there were bound to be ships this close to Earth and he had no easy way to distinguish, from these data alone, an unarmed liner or freighter about her lawful occasions from a Naval cruiser in angry pursuit.
But the New Frontiers had more resources for analyzing what was around her than had an ordinary ship; she had been specially equipped to cope unassisted with any imaginable strange conditions. The hemispherical control room in which they lay was an enormous multi-screened television receiver which could duplicate the starry heavens either in view-aft or view-forward at the selection of the pilot. But it also had other circuits, much more subtle; simultaneously or separately it could act as an enormous radar screen as well, displaying on it the blips of any body within radar range.
