They were still separated, two on one side of the airlock, two on the other. "I'm going to try to look," Capt. Wilkins said. "Let me go." He lumbered directly away from the dome for a distance of about fifteen feet, then turned and positioned himself, some five feet behind the over to one side and laying on the air tank. The air tank is getting General Finogenov notified Major Winship that the underground blast was red, too. I'm afraid ... it's weakening it.... Redder. Oh, oh." "What?" said Capt. Lawler. the three other Americans. Next morning, before the sunlight exploded, the four of them donned their space suits and went and sat outside the dome, waiting. The sun rose with its bright, silent clap of radiance. Black pools of shadows Major Winship, after receiving the message, discussed precautions with " Capt. Wilkins leaped from his position. He was still floating toward the ground when there was an incredibly bright flare from inside the dome, and a great, silent tongue of flame "Boom! Boom!" said Major Winship in exasperation. emergency watch this morning," he explained to the other Americans. "The one that doesn't speak English." "He's done it deliberately," said Capt. Wilkins, the eldest of the four Americans. "How are we going to know when it's over?" "The static level hasn't gone up much, if at all." "Maybe," Lt. Chandler said, "it's buried too deep." "Maybe so," Major Winship said. "But we can't have the dome fall down around all our ears." He stood. "Whew! You guys stay put." He crossed with the floating moon-motion to the airlock and entered, "Okay," Major Winship said. "We told them this might happen," he added Major Winship whinnied in disgust. " Americans: "Our comrades seem unconcerned." completely. It then abated to something in excess of normal. "Well," Lt. Chandler commented, "even though we didn't build this thing to withstand a moonquake, it seems to have stood up all right." "I guess I was just—" Major Winship began. "Oh, hell! We're losing "Got 'em," Major Winship said a moment later. He peeled back a marker and let it fall. Air currents whisked it away and plastered it against a riveted seam of the dome. It pulsed as though it were breathing and then it ruptured. Major Winship moved quickly to cut out the emergency air supply which sprung a little, and I can't get it to conform over the rivet heads." There was a splatter of static. "Damn!" Major Winship said, "they should have made these things more flexible." "Came through without damage." General Finogenov paused a moment. When "You did this deliberately," Major Winship said testily. repeatedly assuring you there was no danger of a quake—and then to have something like this happen. Oh, this is very embarrassing to me. Is there anything at all we can do?" "What'd they say?" Capt. Wilkins asked. "Larry, General Finogenov said he was very embarrassed by this." his helmet against the speaker and then shook his head sadly. "We can't hear anything without any air." "How do they possibly think—?" "Gentlemen! It doesn't make any difference," Lt. Chandler said. "Some air must already have leaked into this one. It's hard as a rock. A gorilla couldn't extrude it." "Who was supposed to check?" demanded Capt. Wilkins in exasperation. "The only way you can check is to extrude it," Lt. Chandler said, "and if it does extrude, you've ruined it." "That's that," Major Winship said. "There's nothing for it but to yell help." It was an awkward operation that took several minutes. Capt. Wilkins cursed twice during the operation. "I'd hate to live in this thing for any period." "I think these suits are one thing we've got over the Russians," Major Capt. Wilkins raised eyebrows. "What brought this on?" "I was just thinking.... They really got it made, Larry. They've got better than three thousand square feet in the main dome and better than "They've got the power-plants for it." "Do you think he did that deliberately?" Major Winship asked. "I think he's trying to force us off. I think he hoped for the quake. Gagarin's built to take it, I'll say that. Looks like it, anyhow. You don't suppose they planned this all along? Even if they didn't, they sure got After a moment, Major Winship said bitterly, "To hell with the Russian They roused Earth. "Is everything all right?" Major Winship was squirming nervously, obviously perturbed. "What's wrong?" came the worried question. In the background, he heard was not entirely subvocal, since he emitted a little gasping cry in "All right? Are you all right?" of American warnings that such a disturbance might release accumulated stresses in the long undisturbed satellite, and was done in the face of vigorous American protests." being inserted. Another tap indicated it was seated. Major Winship flicked the appropriate chest button and nodded in appreciation. "However," he continued, "we did experience a minor leak in the dome, which is presently being repaired." "The Soviet Union," came the reply, "has reported the disturbance and "You're kidding," said Capt. Wilkins. "Actually, I think you guys have got the general wrong," Capt. Lawler said. "He was out, himself, to greet us. I think he was really quite upset by the quake. Probably because his people had misfigured so bad." "He's too damned suspicious," Major Winship said. "You know and I know why they set that blast off. I tried to tell him. Hell. He looks at me like an emasculated owl and wants to know our ulterior motive in trying scale—" "A little scale?" asked Capt. Wilkins, rolling his eyes at the dome. "That's what I told him. We don't have any little scale." that." "I don't think this is the way to do it," Major Winship said. "Let's back the drum out." "It's not the weight, it's the mass," said Capt. Wilkins brightly. "The hell it isn't the weight," said Lt. Chandler. "That's heavy." He shook perspiration out of his eyes. "They should figure a way to get a mop in here, or a towel, or a sponge, or something. I'll bet you've forgotten how much sweat stings in the eyes." "It's the salt." "Speaking of salt. I wish I had some salt tablets," Major Winship said. "I've never sweat so much since basic." "Want to bet Finogenov hasn't got a bushel of them?" "No!" Major Winship snapped. "I hope this doesn't set on exposure to air." "No," Capt. Lawler said. "It sets by some kind of chemical action. General Finogenov wasn't sure of the English name for it. Some kind of "Out! Out!" Major Winship, Lt. Chandler, and Capt. Lawler, recognizing the sense of urgency, simultaneously glanced at the drum. It was glowing cherry red. in the space suits under the best of conditions, and now, with the necessity for speed, was doubly so. The other two crashed into them from behind, and they spewed forth from the dome in a tangle of arms and legs. The table remained untouched. When they halted, Capt. Wilkins said, "Get to one side, it may go off like shrapnel." They obeyed. "What—what—what?" Capt. Lawler stuttered.
