General Finogenov notified Major Winship that the underground blast was scheduled for the following morning. Major Winship, after receiving the message, discussed precautions with 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. "Help?" " Nyet ," said Major Winship, exhausting his Russian. "When?" "Boom—boom!" said Pinov. "Ah, it's all Russian. A moth's wing of dust would, perhaps, rise and settle beyond the horizon: no more. "I'll try again," Major Winship said and switched to the emergency channel. He crossed with the floating moon-motion to the airlock and entered, closing the door behind him. His foot was lifted for the second step when the floor beneath him rose and fell gently, pitching him forward, off balance. "Well," Lt. Chandler commented, "even though we didn't build this thing to withstand a moonquake, it seems to have stood up all right." 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.

The Soviet base was situated some ten miles toward sunset at the bottom of a natural fold in the surface. At that point, the best pathway angled left and made an S-shaped descent to the basin. Major Winship, with his deficient reefer, remained behind. "I'll load you," Capt. Wilkins volunteered wearily.
