“Let the watch officer do that. You go down and get some sleep. I’ll ease her over until we get close enough to use the optical range finder.”
“Thanks, I will.”
Within a few minutes the word had spread around the ship that Eighty-eight had been sighted. Libby crowded into the starboard troop deck with a throng of excited mess mates and attempted to make out their future home from the view port. McCoy poured cold water on their excitement.
“By the time that rock shows up big enough to tell anything about it with your naked eye we’ll be at our grounding stations. She’s only about a hundred miles thick, yuh know.”
And so it was. Many hours later the ship’s announcer shouted:
“All hands! Man your grounding stations. Close all airtight doors. Stand by to cut blowers on signal.”
McCoy forced them to lie down throughout the ensuing two hours. Short shocks of rocket blasts alternated with nauseating weightlessness. Then the blowers stopped and check valves clicked into their seats. The ship dropped free for a few moments — a final quick blast — five seconds of falling, and a short, light, grinding bump. A single bugle note came over the announcer, and the blowers took up their hum.
McCoy floated lightly to his feet and poised, swaying, on his toes. “All out, troops — this is the end of the line.”
A short chunky lad, a little younger than most of them, awkwardly emulated him, and bounded toward the door, shouting as he went, “Come on, fellows! Let’s go outside and explore!”
The Master-at-Arms squelched him. “Not so fast, kid. Aside from the fact that there is no air out there, go right ahead. You’ll freeze to death, burn to death, and explode like a ripe tomato. Squad leader, detail six men to break out spacesuits. The rest of you stay here and stand by.”
The working party returned shortly loaded down with a couple of dozen bulky packages. Libby let go the four he carried and watched them float gently to the deck. McCoy unzipped the envelope from one suit, and lectured them about it,
“This is a standard service type, general issue, Mark IV, Modification 2.” He grasped the suit by the shoulders and shook it out so that it hung like a suit of long winter underwear with the helmet lolling helplessly between the shoulders of the garment. “It’s self-sustaining for eight hours, having an oxygen supply for that period. It also has a nitrogen trim tank and a carbon dioxide water-vapor cartridge filter.”
He droned on, repeating practically verbatim the description and instructions given in training regulations. McCoy knew these suits like his tongue knew the roof of his mouth; the knowledge had meant his life on more than one occasion.
“The suit is woven from glass fibre laminated with nonvolatile asbesto-cellutite. The resulting fabric is flexible, very durable; and will turn all rays normal to solar space outside the orbit of Mercury. It is worn over your regular clothing, but notice the wire-braced accordion pleats at the major joints. They are so designed as to keep the internal volume of the suit nearly constant when the arms or legs are bent. Otherwise the gas pressure inside would tend to keep the suit blown up in an erect position and movement while wearing the suit would be very fatiguing.
“The helmet is moulded from a transparent silicone, leaded and polarized against too great ray penetration. It may be equipped with external visors of any needed type. Orders are to wear not less than a number-two amber on this body. In addition, a lead plate covers the cranium and extends on down the back of the suit, completely covering the spinal column.
“The suit is equipped with two-way telephony. If your radio quits, as these have a habit of doing, you can talk by putting your helmets in contact. Any questions?”
“How do you eat and drink during the eight hours?”
“You don’t stay in ’em any eight hours. You can carry sugar balls in a gadget in the helmet, but you boys will always eat at the base. As for water, there’s a nipple in the helmet near your mouth which you can reach by turning your head to the left. It’s hooked to a built-in canteen. But don’t drink any more water when you’re wearing a suit than you have to. These suits ain’t got any plumbing.”
