They crowded into a carriage on tracks set into the inner wall of the outer hull. She observed thick layering of foamlike material, evidently insulation. Heat loss could be a formidable problem in deep space, as would heat gain, if the ship moved into close orbit about a star.
Suddenly the vehicle was moving, accelerating to frightening velocity. The stanchions supporting the inner decks moved past at such a rapid rate they began to take on the appearance of the strings of a giant Mintakan harp plant, or the trunks of forest vines in Yael’s memory of her home planet. How glad she was to be riding instead of running! Slammer followed behind, having no problem with the velocity.
Then the carriage climbed. At first this increased her weight, making her sagging flesh chafe against a suit built for a male torso, but soon it lightened as they came into the region of decreased gravity. Melody realized that they had passed the officers’ section and were heading into the sword-blade—the solar collector. The ship narrowed, forcing the ascent though they remained at the hull. If the job were near the axis, gravity would be mild. Thank the God of Hosts!
They coasted to a stop and jumped out. Now they ran down a short passage to a vast airlock. Melody felt dizzy and uncoordinated. Not the effect of the intoxicant, she decided, but the half-gravity of this region. This business of gravity constantly changing with elevation was intellectually comprehensible, but took some getting used to in practice. The men, however, seemed to be used to it.
Slammer joined them. Now at last Gary noticed her. “Yael!” he cried. “You can’t come out here!”
Melody shrugged. “Why not?”
“Hurry it up,” another suited figure snapped. “We’re slow already. Crew B will pick up merits.”
There must be competitive interactions between crews, encouraging better performance. Good system, Melody thought.
Gary hesitated only momentarily. “All right, Yael, stay tight on my tail. I don’t have time now to take you back to your level. If anything happened to you…”
The lock closed. Pressure diminished, making her suit become rigid, although it was still flexible at the joints. Then the outer lock opened, swinging outward, and the huge dome that was one indentation of the tripartite sword-blade lay before them.
Dome? It should be a valley, thought Melody. But then she realized: Centrifugal gravity drew toward the outside, not the center. The lock opened from a bubble in the sword-handle; the entire ship was over her head. It just didn’t seem that way from the inside.
The others went out, moving with peculiar dragging dancelike steps. Melody tried to follow—and found that the magnetic boots of the suit were holding her rooted to the deck.
“Go on out,” the man behind her said gruffly. “Haven’t you ever been on-hull before? We have to clear the lock.” He did a tap dance around her and was out.
Melody imitated his motions, and found that only the heel parts of her spaceboots were magnetic; the toe parts had no pull. Thus by pressing down on one toe she was able to draw the heel free without threatening her overall balance. Or so she thought. But suddenly it let go, causing her to lurch frighteningly. Fortunately her other foot held firm. She was grateful the pull was so strong; no danger of falling off accidentally.
Clumsily, she heeled-and-toed after the last man. She was able to diminish the lurches by levering each heel up just so, not too much or too little. The man walked right around the curved lock until he was hanging from the top, then stepped out on the hull itself. Melody, still preoccupied with her walking, discovering how to lengthen her stride so as to make her heels pull up automatically behind, did not fully realize what was happening until she felt the blood impacting in her head. She was inverted!
Now she was hanging precariously from the huge hull. The half-gravity pull seemed like double-gravity; one slip and she would fall into the bottomless well of space! She was abruptly terrified.
But with an effort of will she reoriented. She was not hanging, she was standing, the great mass of the ship below her. Before her was now the valley of solar reflection. Yes, that was better!
“Here we are in a suit on the Ace of Swords,” Melody said to Yael. “A suit of space and of Tarot.” But the host was too frightened of the vacuum overhead to respond to the pun.
The surface of the blade was mirror-bright, a concave reflector that focused the sun’s rays on a suspended trough collector above it. From a distance the trough had been invisible, but now it loomed above like a guyed moon. At the moment it was dark, because this face of the sword was opposite the sun, but Melody knew that very soon that would change as the rotation of the ship brought this mirror sunside.
“It’s in the trough,” Gary’s voice said in her headphone. “Meteorite severed one guy. See it listing there?” He pointed, and indeed Melody could see it: the trough bent to the side. “We have to reconnect that wire before the next pass and tie it fast. We’ll have maybe five minutes. If that focused energy hits us…”
Melody understood. The light of the nearby star was powerful, and focused it would be hundreds of times as strong; that was the point of this setup. A man in that region would be fried, his suit exploding from the heat.
“Here she comes!”
The sword accelerated, seeming almost to yank Melody free of the deck. “What?” she exclaimed involuntarily.
“The blades are geared to orient squarely on the sun,” Gary explained tersely. “An even rate of turning would lose as much as fifty percent of the available energy due to imperfect angles of reception, missing the trough, and so on. So it clicks over the lean aspects more quickly. Uses up some energy, but gains much more. The whole blade’s on a separate axle, of course. We could stop it turning entirely if we had to, without messing up ship’s grav. But since the troughs are held in place by centrifugal force, that’s not advisable ordinarily.”
“I had no idea there was such sophistication in space,” Melody said, genuinely impressed. Indeed, it was evident that her prior education had been scant. She had thought that the philosophical reaches of Tarot encompassed most of what was important. Next time the Ace of Swords appeared in a reading, she would react to it with a vastly changed perspective!
“A thousand years of experience,” he said nonchalantly. “Look—sunrise.”
Mighty Etamin was rising rapidly over the valley horizon. The double star was too brilliant to look at directly, but she followed its progress by the moving shadows. It shoved its way almost directly overhead. Then the gearing slowed the rotation, causing Melody to fall abruptly to the side, and the star stood almost still.
Melody was intrigued. “It used to be a fable, about making the sun stand still,” she murmured.
Gary spoke to the others. “I’ll jet out with the replacement cord as soon as the sun sets. Put the safety on me, and haul me in in a hurry if I run late. I’m too young to fry.”
Efficiently they attached jet-pack and safety line to him. Then as the star commenced its movement offstage, Gary took off. Like a shooting star he streaked into the half-dusk, trailing two lines, the jets augmenting the initial boost of centrifugal force. As he passed through the slanting beam of the vanishing star, the light refracted from portions of his suit in a splay of rainbow colors, a splendid effect.
“Superman,” Yael remarked.
Gary angled the jet at apogee just as the star set. He maneuvered for what seemed like an unconscionably long time before coming to rest. Melody realized that space jetting was more tricky than it looked, especially with the drag of lines changing the vectors. Several minutes passed before he got the old wires removed and the new ones threaded. Then the sword rotated again.
