They were still separated, two on one side of the airlock, two on the other. "I can see it," he said. "It's getting redder. It's ... it's ... melting, yes. Melting down at the bottom a little. Now it's falling over to one side and laying on the air tank. The air tank is getting red, too. I'm afraid ... it's weakening it.... Redder. Oh, oh." General Finogenov notified Major Winship that the underground blast was bright flare from inside the dome, and a great, silent tongue of flame table was sent tumbling. The flame was gone almost instantly. "There went the air," Capt. Lawler commented. Progress. When—boom?" "Boom! Boom!" said Major Winship in exasperation. "Boom!" said Pinov happily. "Boom—boom!" said Pinov. Americans. "How are we going to know when it's over?" shadows evaporated. One by one they clicked on their cooling systems. In the airless void of the moon, the blast itself would be silent. A "Nope." probably over by now." "No. I've got to cool off." "The shot probably went off an hour ago." "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, "Charlie! Charlie!" "It's—" "I guess it's over," said Major Winship, getting to his feet. "Wait a 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 pressure. Where's the markers?" "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 had cut in automatically with the pressure drop. "You guys wait. It's "We've lost about three feet of calk out here," Capt. Lawler said. "I can see more ripping loose. You're losing pressure fast at this rate." Major Winship pressed the sheeting over the leak. "How's that?" "Not yet." "I don't think I've got enough pressure left to hold it, now. It's 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." to slide downward, then it fell away completely and lay limply on the floor. "Major Winship! Hello! Hello, hello, hello. You A Okay?" "This is Major Winship." "Oh! Excellent, very good. Any damage, Major?" "Little leak. You?" "Came through without damage." General Finogenov paused a moment. When no comment was forthcoming, he continued: "Perhaps we built a bit more seismic data out of that shot.... Well, to hell with them, let's get this leak fixed. Skip, can you get the calking compound?" "Larry, where's the inventory?" his helmet against the speaker and then shook his head sadly. "We can't hear anything without any air." "That's right, isn't it." "Let's see. Squeeze the tube until the diaphragm at the nozzle ruptures. Extrude paste into seam. Allow to harden one hour before "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 "You got any concentrate? I'm empty." cursed twice during the operation. "I'd hate to live in this thing for any period." 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 twelve hundred square feet in each of the two little ones. And there's "Is everything all right?" Capt. Wilkins's lips were desperately forming the word "Leak?" Air, Major Winship said silently. Leak? Bottle! Bottle! Bottle! It was a frog-like, unvocal expletive. "... Freedom 19! Hello, Freedom 19! Come in!" "All right? Are you all right?" Soviet Union fired an underground atomic device for the The turn was uncomfortably tight and complicated by the restraining cables. Capt. Wilkins began replacement of the air bottle. "These protests have proved well founded," Major Winship continued. "Immediately following the detonation, Freedom 19 was called on to withstand a moderately severe shifting of the Lunar surface. No personnel were injured and there was no equipment damage." 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 has tendered their official apology. You want it?" "It can wait until later. Send it by mail for all I care. Vacuum has destroyed our organic air reconditioner. We have approximately three weeks of emergency air. However, Base Gagarin reports no damage, so that, in the event we exhaust our air, we will be able to obtain the necessary replacement." be able to deliver replacements in about ten days." "I will forward a coded report on the occurrence," Major Winship said. "Let us hear from you again in ... about three hours. Is the leak repaired?" "The leak has not yet been repaired. Over and out." He nodded to Capt. Wilkins and leaned back. Methodically, Capt. Wilkins set about disconnecting the major from the why they set that blast off. I tried to tell him. Hell. He looks at me It took the four of them to roll the drum inside, rocking it back and forth through the airlock. At that time, it was apparent the table was interposing itself. back the drum out." Eventually, they accomplished the moving. They wedged the drum between the main air-supply tank and the transmitter. They were all perspiring. "It's the salt." "No!" Major Winship snapped. "Watch it! Watch it! You almost hit me in the face plate with that!" "Now what, Skip? The instructions aren't in English." "You're supposed to dump the bucket of stuff in. Then clean the area for about ten minutes or so. Then you apply it. It sets for service in "I hope this doesn't set on exposure to air." "No," Capt. Lawler said. "It sets by some kind of chemical action. plastic." "Let's come back to how we're going to clean around the leak," Major an epoxy! Let's get out of here." "Out! Out!" He and the Major reached the airlock at the same time and became 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. like shrapnel." They obeyed.
