“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 old-fashioned 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.
