The Recluse
Chapter V: Vacuum
by Rich Reifsnyder
"Warning: depressurization. Air pressure at 68% of
normal..."
Murphy’s Law states "Anything that can go wrong,
will go wrong." Jason Blake was discovering that the hard
way: though the odds against it happening on his voyage
were several thousand to one, a meteoroid had breached the
hull of his fragile capsule. He had less than thirty seconds to
don his spacesuit before the reduced pressure would pull the
air out of his lungs.
His first reaction was to hyperventilate, to saturate his
blood with oxygen while he still could. It would be impossible
to hold his breath in once the cabin was in vacuum. To the
side of the cockpit seat was his spacesuit.
He grabbed the pants, and slapped the buckle of his
safety belt to free himself from the seat. The suit was made
of spandex, which provided skintight pressure and was safer
than the balloon suits NASA used to hold in an atmosphere.
He tugged hard on the suit; the legs of his sleepwear bunched
up painfully around his shins.
He grabbed the upper
garment, which for safekeeping
had the helmet already latched in
place, and as he slipped it on he
found it more and more difficult
to breathe. Finally he sucked in
as much air as possible, held it
for several seconds, and forced it
out explosively. He could no
longer breathe.
He prayed that the
backpack with the two oxygen
tanks was full. He couldn’t
remember whether he had checked
it after his last EVA. His throat was constricting; he couldn’t
even gasp. He shut his eyes to prevent them from rupturing
and fumbled around for the rigid tube that connected to the
oxygen tank. He guided it into the valve over his neck.
The blast of cold oxygen burned his throat but soothed
the pressure in his lungs. "Warning: depressurization. Air
pressure at 7% of normal," chanted the computer over his
suit radio. His task now was to find the leak in the hull and
seal it.
He suddenly became aware of a new kind of pressure.
He thought at first it was a heart attack, but then realized
that, in the reduced pressure, the small amount of nitrogen in
his blood was bubbling and vaporizing in his blood vessels.
It was the bends.
He could barely move his fingers, and the pain was
spreading to his chest, stomach, legs, and even his neck. With
this sort of pain he would only have a few minutes to seal the
leak before he blacked out, not the hours afforded him by the
oxygen tanks.
He opened a closet and picked out one of his books.
His fingers were on fire as he grabbed the pages of the books
and ripped them out. He let them drift in midair and hoped
they were large enough not to clog the air ventilators.
He found another spacesuit oxygen tank and opened
the valve full blast. Then he held it toward the wall, so that
the air would fill the room without whipping the pages around.
As he watched, the paper flapped in the breeze, but several
sheets were converging at a point near the hatch. They slapped
into the hull, and then a hole a few centimeters in diameter
was ripped in them.
Blake closed the oxygen valve, located the hull repair
kit and drifted over to the leak with the kit and the oxygen
tank. He pulled the paper away, and stuffed it through the
hole, one page at a time, so he could be rid of them. He
rummaged through the repair kit and found a single disc patch.
It was an insulation-filled wheel of carbon fiber, ten
centimeters in diameter and a centimeter thick. He sprayed
epoxy in a ring on one surface of the patch using a squeeze
tube, and a layer of binder in a ring around the little hole in
the hull. He pressed the disk in place.
Then he opened the
oxygen valve yet again to
partially pressurize the cabin.
The pressure, with any luck,
would hold the disk in place. He
sprayed epoxy around the edge
of the patch and then a layer of
insulation foam. He waited for
two minutes, the pain in his
joints throbbing.
He wasn’t sure if the
epoxy was dry but couldn’t
stand it any longer. He sailed
through the ship turning the
ventilators back on to flood the
cabin with fresh oxygen and nitrogen. Soon he could hear
the computer calling its notices from outside is helmet in
addition to the suit radio: "Air pressure at 90% of normal.
Air pressure at 95% of normal. Air pressure normal."
He took off his helmet and inhaled deeply. The pain in
his joints had diminished to a dull ache. He inspected the
patch, carefully prodded it to see if the epoxy had bonded.
He heard the radio chime; it was a call from Mission
Control. "Jason, please report in! We’ve just received a
broadcast that you’re losing atmosphere. Please report in so
we can advise you on the solution."
Blake smiled, then broke out into raucous laughter.
"Don’t worry about a thing, MC, the situation is under
control." He had performed the first spacecraft repair without
Earth ground support in human history.
With only one month to go in his interplanetary voyage,
he knew he would enjoy smooth sailing.
