Bracing himself against the curving steel hide of the shell, he pushed at
the vision-plate. But he could exert little effort. Lack of gravity,
inability to brace himself securely, made the task a hard one. Rising to
his feet, he stamped his heavy boots against the glass, but the plate
refused to budge.
As a last desperate effort, he might use his guns, blast his way into the
shell. But that would be long, tedious work... and there would be a certain
danger. There should be, he told himself, an easier and a safer way.
Suddenly the way came to him, but he hesitated, for there lay danger, too.
He could lie down on the plate, turn on the rocket tubes of his suit and
use his body as a battering ram, as a lever, to force the stubborn hinges.
But it would be an easy matter to turn on too much power, so much power
that his body would be pounded to a pulp against the heavy quartz.
Shrugging at the thought, he stretched flat on the plate, hands folded
under him with fingers on the tube controls. Slowly he turned the buttons.
The rockets thrust at his body, jamming him against the quartz. He snapped
the studs shut. It had seemed, for a moment, that the plate had given just
a little.
Drawing in a deep breath, he twisted the studs again. Once more his body
slammed against the plate, driven by the flaming tubes.
Suddenly the plate gave way, swung in and plunged him down into the
laboratory. Savagely he snapped the studs shut. He struck hard against the
floor, cracked his helmet soundly.
Groggily he groped his way to his feet. The thin whine of escaping
atmosphere came to his ears and unsteadily he made his way forward. Leaping
at the plate, he slammed it back into place again. It closed with a thud,
driven deep into its frame by the force of rushing air.
A chair stood beside a table and he swung around, sat down in it, still
dizzy from the fall. He shook his head to clear away the cobwebs.
There was atmosphere here. That meant that an atmosphere generator still
was operating, that the ship had developed no leaks and was still airtight.
He raised his helmet slightly. Fresh pure air swirled into his nostrils,
better air than he had inside his suit. A little highly oxygenated,
perhaps, but that was all. If the atmosphere machine had run for a long
time unattended, it might have gotten out of adjustment slightly, might be
mixing a bit too much oxygen with the air output.
He swung the helmet back and let it dangle on the hinge at the back of the
neck, gulped in great mouthfuls of the atmosphere. His head cleared
rapidly.
He looked around the room. There was little that he had not already seen. A
practical, well-equipped laboratory, but much of the equipment, he now
realized, was old.
Some of it was obsolete and that fitted in with all the rest of it.
A framed document hung above a cabinet and getting to his feet, he walked
across the room to look at it. Bending close, he read it. It was a diploma
from the College of Science at Alkatoon, Mars, one of the most outstanding
of several universities on the Red Planet. The diploma had been issued to
one Caroline Martin.
