Space Platform by Murray Leinster

Joe sat on the porch of Major Holt's quarters in the area next to the Shed. It was about eight-thirty, and dark, but there was a moon. And Joe had come to realize that his personal disappointment was only his personal disappointment, and that he hadn't any right to make a nuisance of himself about it. Therefore he didn't talk about the thing nearest in his mind, but something else that was next nearest or farther away still. Yet, with the Shed filling up a full quarter of the sky, and a gibbous moon new-risen from the horizon, it was not natural for a young man like Joe to speak purely of earthly things.

"It'll come," he said yearningly, staring at the moon. "If the Platform gets up day after tomorrow, it's going to take time to ferry up the equipment it ought to have. But still, somebody ought to land on the moon before too long."
