The engineer did not look out the ports at all. He watched the screen before him. There was a vertical line across the side of the lighted ship. A blip moved downward across it, showing their height in thousands of miles. After a long time the blip reached the bottom, and the vertical line became double and another blip began to descend. It measured height in hundreds of miles. A bright spot--a square--appeared at one side of the screen. A voice muttered metallically, and suddenly seemed to shout, and then muttered again. Bordman looked out one of the black ports and saw the planet as if through smoked glass. It was a ghostly reddish thing which filled half the cosmos. It had mottlings, and its edge was curved. That would be the horizon. The engineer moved controls and the white square moved. It went across the screen. He moved more controls. It came back to the center. The height-in-hundreds blip was at the bottom, now, and the vertical line tripled and a tens-of-miles-height blip crawled downward. There were sudden, monstrous plungings of the landing-boat. It had hit the outermost fringes of atmosphere. The engineer said words it was not appropriate for Aletha to hear. The plungings became more violent. Bordman held on, to keep from being shaken to pieces despite the straps, and stared at the murky surface of the planet. It seemed to be fleeing from them and they to be trying to overtake it. Gradually, very gradually, its flight appeared to slow. They were down to twenty miles, then. Quite abruptly the landing-boat steadied. The square spot bobbled about in the center of the astrogation-screen. The engineer worked controls to steady it. The ports cleared a little. Bordman could see the ground below more distinctly. There were patches of every tint that mineral coloring could produce, and vast stretches of tawny sand. A little while more, and he could see the shadows of mountains. He made out mountain-flanks which should have had valleys between them and other mountain-flanks beyond, but they were joined by tawny flatnesses instead. These, he knew, would be the sand-plateaus which had been observed on this planet and which had only a still-disputed explanation. But he could see areas of glistening yellow and dirty white, and splashes of pink and streaks of ultramarine and gray and violet, and the incredible red of iron oxide covering square miles--too much to be believed. The landing-boat's rockets cut off. It coasted. Presently the horizon tilted and all the dazzling ground below turned sedately beneath them. Then came staccato instructions from a voice-speaker, which the engineer obeyed. The landing-boat swung low--below the tips of giant mauve mountains with a sand-plateau beyond them--and its nose went up. It stalled. Then the rockets roared again--and now, with air about them, they were horribly loud--and the boat settled down and down upon its own tail of fire.
