Grim Green World

Why had five spaceships, each tested again and again right down to its tiniest rivet, started for the Moon and ended up in Hell?
I lit the last cigarette I would ever smoke and took my airsuit out of the compartment under the control-board. The two-man cubicle was coffin-cold even under the blast of sunlight pouring through the forward port, and the air smelled of stale tobacco and machine oil. Beside me Charlie Kosta's voice droned into the communicator, winging back two-hundred thirty thousand miles to the listening millions of Earth.
Our air is nearly gone, Charlie said. We have about twelve minutes left for deceleration, but we'll never make landing. The Luna V is riddled like a sieve, spewing out heavy-water fuel along with her air ... it's a miracle that a chunk hasn't crashed through our fuel pile or the communicator—or through us. That's what blew up the first four ships, we know now ... if men ever reach the moon they'll first have to develop some sort of armor that will turn this barrage of meteoric dust.
I got my feet into the plastoid suit and pulled it on, letting the transparent headpiece dangle over one shoulder like a parka hood. Charlie watched me with his tight grin, waiting through the three-second lag of time for Earth's answer. Some high-ranking general down there had pushed aside the Moon Foundation scientists to make himself heard; his voice came over the hiss of static with a tinny, frantic ring.
Meteoric dust couldn't possibly pierce that alloy hull! It was tested over and over—
We waited him out, knowing that his frenzy was not for us nor for the success of space flight. He was concerned, like all the military, only with the establishing of a moon base to overlook Earth, an all-commanding launching site that would control a world. Once that base was established, the ferment of war would come to a bitter end; one nation would own the planet.
But you didn't test the hull out here, Charlie said patiently when the general had finished. You can't imagine the speed of these particles. We've no protecting atmosphere to vaporize them, as Earth has, and they streak through the ship so fast that they seem to strike both sides of the hull at once.... I'm cutting you over to Leonard Nugent now. Ready, Len?
